1: Introduction 1.1 Product Overview The Lantronix ETSs (ETS4P, ETS8P, ETS16P, ETS16PR, ETS32PR, and ETS422PR) are Multiport Device Servers that provide shared network access to terminals, devices, console ports, and printers for a variety of network protocols and operating systems. The ETS supports the TCP/IP, IPX (NetWare), Local Area Transport (LAT), AppleTalk (EtherTalk), and Microsoft LAN Manager protocols.
Terms Introduction 1.3 Terms In this manual, the following terms are used to describe parts of a network. See the Glossary for more detailed explanations of these terms. host A computer, sometimes referred to as a CPU, attached to the network. The term host node Any intelligent device directly connected to the Ethernet network and having its own Ethernet addresses, such as a host, an Ethernet printer, or a terminal or print server. Devices connected to the ETS are not nodes.
Introduction Server Features Connectivity The Server connects terminals directly to the network, which conserves physical ports on the host, allows the terminal to access more than one host, and simplifies terminal cabling. Multiple Session Support Users can open multiple outgoing LAT, Rlogin, and Telnet sessions, and can easily switch among active sessions. Up to eight sessions are supported per connected terminal. Each session can be connected to any host and can use any supported protocol.
Server Features Introduction Command Line Interface A simple but powerful command interface is provided for both users and system managers. The ETS operating code is downloaded automatically at power-up, making software upgrades as easy as copying a file. The ETS stores its operating software permanently on-board, so it does not need to download code unless new versions become available. Servers can also be configured to request a downloaded configuration file at boot time.
Introduction ❍ How To Use This Manual An IP security table, which allows the server manager to restrict incoming and outgoing TCP/IP connections to certain ports and hosts. This allows managers to restrict Server access to a particular local network segment or host. It also allows restrictions for SLIP access to the network. DHCP Support The Server can obtain an IP address from a DHCP server at boot time.
How To Use This Manual Introduction ◆ Chapter 12, Command Reference, lists the ETS command set in detail, including syntax, options, errors, examples, and where to find related information. ◆ Appendices provide supplementary information, including Technical Support contact information, troubleshooting tips, and pinout information. Note: 1-6 Installation and cabling are covered in your Server’s Installation Guide.
2: Concepts The ETS provides two major functions: outgoing sessions, which are basically interactive connections to other nodes, and incoming connections to services, such as printer and modem support. 2.1 Services Services are the basic method of connecting to the ETS from any host or another server. In general, a service is required on the ETS before any job or connection queueing will take place. See the Server Configuration chapter for details on creating and using services. 2.
Network Protocols Concepts 2.2.3 RS-422 The ETS422PR supports RS-422 on all of its ports. RS-422 is different from RS-232 or RS-423 in that it is a differential or balanced line interface standard. It is designed for longer cabling distances (approaching 4,000 feet) in noisier electrical environments, and it can be used in multi-drop networks with one driver and up to ten receivers. The maximum speed of the RS-422 ports on the ETS422PR is 230.
Concepts AppleTalk 2.4 AppleTalk AppleTalk is a protocol used primarily by Apple Macintoshes to access network resources such as file servers and printers. AppleTalk is also available for UNIX, NetWare, and other operating systems. The AppleTalk protocol can be run over Ethernet (EtherTalk), Token Ring (TokenTalk), or LocalTalk, which is a medium speed network type built into every Macintosh.
LAN Manager Concepts Zones, like nodes, originate from and are configured on AppleTalk routers. One zone on each network will be chosen by the router as the default zone. If there are no AppleTalk routers on the network, there will be only one zone (the default zone) of which all nodes are members. If no zone name has been previously defined on the ETS, or if the defined zone is no longer valid, the ETS will join the default zone and no other configuration is needed.
Concepts LAT LAN Manager node lookups take a text resource name and resolve it into a hardware address. For this reason, node and resource names must be unique on the network, and the ETS will print an error message if any configuration that violates this rule is attempted. Note: NetBIOS can be run over TCP/IP, but the ETS does not support this mode of operation. 2.
LAT Concepts In general, all services offered by the ETS are associated with one or more ports; exceptions to this rule will be noted later. Figure 2-2 shows an example of services offered on a network.
Concepts TCP/IP Suppose Bob is logged into port 4 on his ETS and the server manager has given port 4 access to groups 1, 7, 13, and 105. Bob, or anyone else using port 4, can only access services that have one of those group numbers. Suppose Bob wishes to access a modem on a different server. If the server to which the modem is attached allows access to groups 8, 12, 16, 42, and 105; Bob will be allowed to use the modem because he and the modem service have group 105 in common.
TCP/IP Concepts 2.7.2 Telnet Telnet is an industry-standard network protocol. Networks that support Telnet can (and do) stretch for thousands of miles and contain thousands of hosts. The theory behind Telnet is that a user anywhere on the network can access a foreign host and start a terminal session. The user does not have to worry about what kind of computer or operating system he is dealing with, and the remote host does not need to know the type of terminal the user is using.
Concepts TCP/IP 2.7.2.2 Rlogin In addition to Telnet, ETS users can use the Rlogin application to connect to remote TCP/IP hosts. Rlogin is similar to Telnet, but it can be configured to allow trusted users to log into a host without password verification. For this reason, Rlogin can be a security problem, and is not enabled on all sites. TCP/IP Server Parameters on page 4-5 explains how to set up Rlogin access and discusses the methods of user verification.
TCP/IP Concepts Text names make it unnecessary to remember long strings of address numbers. For example, suppose user Bob wishes to log into a host named “alex.weasel.ctcorp.com.” The other hosts on the network have no knowledge of which piece of hardware is associated with this name, so the ETS must translate the name into a numeric address, such as 199.25.172.6. After the name is translated (or resolved), the connection can be attempted. See Set/Define Server Domain on page 12-65 for more information.
Concepts TCP/IP If your ETS has boot mode DHCP support, the ETS will attempt to acquire an IP address via DHCP at boot time. If it succeeds, the ETS will save the IP address into NVR and continue with the boot process. Once running, the ETS’s operational code will attempt to acquire the same IP address from the DHCP server. If for some reason the runtime DHCP request fails (for example, if there is no response for 15 seconds), the ETS will use the address saved in NVR.
TCP/IP Concepts 2.7.6 Serial Line Internet Protocol (SLIP) The SLIP protocol allows hosts to communicate via TCP/IP over a serial line instead of Ethernet. Due to the point-to-point nature of serial lines, only two hosts can communicate over a single line. SLIP is most frequently used for dialup modem lines, where a SLIP-equipped TCP/IP host can dial into the ETS, begin a SLIP session, and thus gain access to the network attached to the ETS.
Concepts TCP/IP The SLIP section of the Server Configuration chapter covers SLIP setup and other restrictions. 2.7.7 Simple Network Management Protocol (SNMP) The ETS supports the SNMP network protocol, which allows hosts on the network to query nodes for counters and network statistics and change some parameters on those nodes. The form of these requests is documented by RFC 1098.
TCP/IP Concepts 2.7.9 LPR Support The ETS and many UNIX systems implement the lpr (Berkeley remote printing) protocol, a protocol that makes it very easy to add print hosts to a system. To add the ETS as a print host, add the ETS’s IP address to a host table and add the ETS’s service name as a print queue. No special host software or other configuration is needed. ETS services can be accessed via the normal lpr commands on the host. Print jobs can be forwarded multiple “hops” in the network.
Concepts LAT and TCP/IP Connectivity Ping Sends a TCP/IP request for an echo packet to another network host to test network connections. Send Enables users on Telnet session to send explicit Telnet control characters, such as Abort Output (AO), Are You There (AYT), and more. 2.8 LAT and TCP/IP Connectivity The service capabilities of the ETS also allow translation between LAT and Telnet protocols.
NetWare Concepts 2.9 NetWare Novell’s NetWare software allows you to link computers together and provide file and printer sharing. It is typically used to network DOS-based PCs, but is starting to appear under UNIX and other operating systems. NetWare is built around file servers, which handle user logins, provide network resources, and control security. At least one file server, such as a PC or UNIX host, is required in any NetWare environment.
Concepts Sessions 2.10 Sessions When a user connects to a service on the network (LAT, Telnet, or Rlogin), he or she creates a session. A non-networked terminal with a dedicated line from the terminal to the CPU is typically limited to a single session—users must log out of the current session before they can connect to new host or service. With the ETS, however, this restriction is eliminated. A user can have several open sessions at a time, although only one is displayed on the screen.
PostScript Concepts See Set/Define Server Session Limit on page 12-80 and Set/Define Port Session Limit on page 12-50 for more information. 2.11 PostScript Many printers (including all LaserWriters and other AppleTalk compatible laser printers) use a printing language called PostScript. Unlike other printer protocols, which typically accept ASCII characters and print them verbatim, PostScript is also a programming language.
Concepts Security The ETS allows ports to be configured with the Dialup and/or DTRwait characteristics. Dialup will tell any LAT service that a port is connected to a modem; the remote node may decide to disallow the connection based on that flag for security reasons. The DTRwait characteristic will force the ETS to de-assert DTR on a port until a user actually connects to the port. This connection can be either an interactive login from a device on the network or a LAT or Telnet service connection.
Security Concepts ◆ Incoming logins can be selectively disabled and/or password protected via the Set/Define Server Incoming command. ◆ The IP security table can be used to restrict logins to the ETS. ◆ Ports used for network logins can be “preconfigured” with a standard set of characteristics for each login. For more information about security measures and restriction options, including some ETS features that are used for more than security reasons, see the Server Configuration and Ports chapters.
Concepts Security 2.13.2 Event Reporting/Logging The ETS can be configured to report various errors and events either to the serial console port or to a network host via TCP/IP (using the syslogd facility), LAT, or NetWare. Events that can be logged include user logins, modem events, printer state changes, system boots, system resets, and a full record of commands issued on the ETS. See Set/Define Logging on page 12-25 for more information.
3: Getting Started This chapter provides background information to get you started using the ETS. Topics include methods used to initially set up the ETS as well as ongoing maintenance issues, such as rebooting and restoring factory default settings. This chapter assumes the following: ◆ The ETS has booted properly and is running its operational code ◆ The ETS is connected to the Ethernet ◆ For IP network users, the ETS has been assigned a valid IP address.
Configuration Methods Getting Started 3.1.2 Using a Web Browser The ThinWeb Manager web browser interface allows you to log into and configure your ETS using a standard web browser with JavaScript enabled. Simply type the ETS IP address or resolvable text name into the browser’s URL/Location field. Figure 3-1: Sample Web Browser Login Once you have connected to the ETS, you will see the Lantronix ThinWeb Manager interface.
Getting Started Entering and Editing Commands 3.2 Entering and Editing Commands In examples throughout the manual, ETS commands and keywords are displayed in uppercase for clarity. They may be entered in upper, lower, or mixed case. The Command Reference chapter displays the syntax of each command, and includes restrictions, known errors, and references to related commands. Optional parameters are enclosed in straight brackets [ ].
Restricted Commands Getting Started Table 3-1: Command Line Editing Keys, cont. Note: Key Purpose Up Arrow or Ctrl-P Recalls the previous command Down Arrow or Ctrl-N Recalls the next command !text Recalls the last command starting with text !! Recalls the last command Line editing is disabled on hardcopy (printer) ports. 3.3 Restricted Commands To prevent unauthorized users from changing server-wide characteristics, some commands require privileged (superuser) status.
Getting Started List Abbreviating Keywords Displays the unit’s permanent settings. Note that some settings that are Listed will not take effect until the unit is rebooted. 3.4.3 Clear and Purge Clear Removes an item immediately, but not permanently. When the unit is rebooted, the old setting will again be in effect. Purge Removes an item permanently, but generally does not take effect until the unit is rebooted.
Maintenance Issues Getting Started 3.6.2 Changing the Server Prompt The prompt each user receives (the Local> prompt) is configurable in a variety of ways. For a basic prompt, enter a command similar to the following. The resulting prompt is shown on the next line. Figure 3-6: Configuring User Prompt Local> SET SERVER PROMPT “Server>” Server> Note: The remote console port prompt cannot be changed.
Getting Started Editing the Boot Parameters 3.6.4 Restoring Factory Defaults Should it become necessary, the ETS can be restored to the default settings installed at the factory. This will restore everything—the ETS will function as though it just came out of the box. Be certain you wish to do this before you start. As mentioned in Section 3.6.3, you can use the Initialize command to reboot the server to its factory default settings. Figure 3-10: Restoring Factory Defaults Local>> INITIALIZE FACTORY 3.6.
System Passwords ◆ Getting Started NetWare fileserver name Boot parameters are edited with Set/Define Server commands. Figure 3-11: Editing Boot Parameters Local>> DEFINE SERVER LOADHOST 192.0.1.8 SOFTWARE “newload” Note: The loadfile name must be placed in quotes to preserve case. 3.8 System Passwords There are three important passwords for the ETS: the privileged password, the login password, and the maintenance password. All three are discussed in the following sections. 3.8.
Getting Started Configuration Files When you are finished entering the privileged commands, it is a good idea to turn off privileged status with the Set Noprivileged command so that you do not inadvertently change settings. 3.8.2 Login Password Each port can be configured to require a login password when in character mode. Users will be prompted for this password when attempting to log into the port.The Local> prompt will not be displayed until the correct password is entered.
Configuration Files Getting Started 3.9.1 Using EZWebCon EZWebCon will examine the current configuration of your ETS, translate this information into a series of commands, and save the commands in a file. This file can be downloaded to configure the ETS. Refer to EZWebCon’s on-line help for more information. 3.9.
Getting Started Configuration Files 3.9.2.2 Configuring the Host The configuration file can be downloaded from a TCP/IP host (via TFTP), from a VMS host (via LAT), or from a NetWare fileserver. In any case, some host configuration will be necessary. ◆ For TFTP loading, enable TFTP loading on your host and place the configuration file in a download directory. ◆ For LAT downloading, install the ets$configd service handler on your VMS hosts. The service handler code is included on the distribution CD-ROM.
Configuration Files Getting Started 3.9.2.4 Download Sequence If the configuration file cannot be downloaded at boot time, the server will retry the download if configured to do so. This behavior is governed by the Startupfile Retry limit. A Retry limit of zero means the ETS will retry forever until it can download the file. Otherwise it will try a specific number of times, then continue booting.
4: Server Configuration After powering up the ETS for the first time, you will want to configure it for everyday use. Most of the parameters discussed in this chapter only need to be set once and can be left alone until a major change is needed. Please refer to the Glossary for more information about unfamiliar terms. Note: IP parameters must be specified before Telnet can be used, and an IP address must be configured before EZWebCon can be used.
AppleTalk Server Parameters Server Configuration 4.1.2.1 Preconfiguring Virtual Ports Incoming LAT or Telnet/Rlogin logins to the ETS do not have a physical port associated with them, since they can appear and disappear at random. Therefore, each such connection receives a virtual port at the time of connection which disappears after logout. These virtual ports are created from a template port, which is the set of characteristics that every network login receives.
Server Configuration LAT Server Parameters 4.3 LAT Server Parameters Two groups of LAT parameters can be specified in order for the ETS to communicate on the network: the ETS’s identification information (its identification string and name) and network timers. In addition, a node limit can be set if desired. 4.3.1 Server Identification Select a short, unique and descriptive name for the ETS, as well as a more descriptive string to be used as the identification string.
NetWare Server Parameters Server Configuration 4.4 NetWare Server Parameters Several NetWare parameters can be configured to ensure that your ETS functions properly on an IPX network. First, Set/Define Server NetWare Loadhost can be used to specify the fileserver from which to download operational code. Figure 4-7: Defining a NetWare Loadhost Local> DEFINE PROTOCOLS NETWARE LOADHOST “loadserv” Other configurable parameters are discussed in the following sections. 4.4.
Server Configuration TCP/IP Server Parameters By default, the ETS will only query local fileservers, but this may still be too many in a large network. The Clear/Purge Protocol NetWare Access command allows you to remove items from the access list. The Set/Define Protocols NetWare Reset command can be used if necessary to force the ETS to rescan all fileservers for pending jobs.
TCP/IP Server Parameters Server Configuration You can also configure a backup host in case the primary one fails. Figure 4-12: Configuring Backup Hosts Local> DEFINE SERVER SECONDARY NAMESERVER 192.0.1.193 Local> DEFINE SERVER SECONDARY GATEWAY 192.0.1.195 4.5.3 Local Host Table If your environment uses a few TCP/IP hosts regularly, you may wish to add hosts to the local host table so that nameserving text names is not necessary (and numeric addresses do not have to be used).
Server Configuration TCP/IP Server Parameters ◆ Until the port is actively running SLIP, it can be used normally as a service port or a login port. If a modem is attached to the port, users can connect to the port and dial out. The port changes to SLIP interpretation only after receiving the Set SLIP command. ◆ After the SLIP session is started, the Local mode of the ETS is not reachable again until the port is logged out, thus terminating the SLIP session.
TCP/IP Server Parameters ◆ Server Configuration The remote SLIP hosts should not need extra routing configuration. The only possible change needed is to make the default route point to the ETS as shown below. You may also wish to configure gateway hosts on the ETS if non-local TCP/IP sessions will be started. Figure 4-15: Specifying Default Route % su # route add default ETSname metric ◆ SLIP connections can be restricted via the Set/Define Server SLIP Password and Set/Define IPsecurity commands. 4.5.
Server Configuration TCP/IP Server Parameters Conversely, the command sequence below will result in a SLIP session that uses the user’s MTU value of 500. Figure 4-20: User’s Settings Taking Precedence Local> DEFINE SLIP DEFAULT MTU 1000 FORCE DISABLED Local> SET SLIP ADDRESS 192.0.1.20 MTU 500 The Force option applies only to the IPaddress, MTU, and Broadcast options. If no IP address is configured (either as a port setting or server default) or specified by the user, the connection will fail.
TCP/IP Server Parameters Server Configuration Port 4 will treat all serial data as SLIP packets until the Autostart option is removed and the port is logged out. The exception to this case is if the port also has Modem Control enabled. If so, a drop in the DSR signal will terminate the SLIP session, and the session will not restart until DSR is re-asserted. A password can be configured to restrict access to SLIP sessions.
Server Configuration ◆ TCP/IP Server Parameters The display also shows counters for fragmentation, reassembly, and packets dropped due to congestion on the SLIP line. The IP errors field shows incoming packets that were discarded due to protocol problems including checksums errors, header problems, and incorrect source hosts. The ETS will discard any packets from the SLIP session that are not from the initially-configured host. 4.5.5.
Creating Services Server Configuration 4.6 Creating Services A service is any resource that can be accessed locally or via the network. For example, a host is a service to which terminals can connect. The ETS can offer its attached devices to the network as services.A Lantronix service is also known as a remote printer name or remote queue name on many operating systems. Autobaud should not be enabled for any port that offers a service.
Server Configuration Creating Services In Figure 4-27, the service rating is non-zero, indicating that the service is available for connections. If the service rating were zero, the service would not be available. This can happen if the port is not configured for Dynamic or Remote access, if connections are disabled, or if the service/port is in use.
Creating Services Server Configuration ◆ Log the port out so that the Define commands take effect. ◆ Create a print service on the port that allows connections and queueing by default, and enable the server send out an identification string in network multicasts.Create a print service on port 2, and enable the ETS to send out an identification string in network multicasts. ◆ Save the service so that it will be enabled after the next server reboot. 4.6.
Server Configuration Creating Services Table 4-1: Service Options, cont. Option Function Postscript If enabled, queries the printer (via Ctrl-D exchanges) to make sure it is ready for a new job before starting any job. Any service supporting only a PostScript printer should also have this flag enabled. PSConvert If enabled, encapsulates text sent to the service in a PostScript wrapper. This allows text-only queues to print to PostScript devices. RTEL Enables or disables RTEL access to the service.
Security Server Configuration Since modems do not log the user out when a connection is finished, you will probably want to have the Break or Local key available so you can return to the ETS command line; see Set/Define Port Local for more information. If you wish to disconnect from the modem session, use the Disconnect or Logout command. If a port and modem are to be used to allow dial in connections, you may wish to make the port Secure.
Server Configuration Security Like other configurations, security table entries can be Set or Defined. To add an entry to the table, specify an IP address (or range), which direction(s) to restrict, and a list of affected ports. Figure 4-33: Setting Server Access Local> SET IPSECURITY 192.0.1.255 OUTGOING DISABLED PORT 4-7 In order, the command in Figure 4-33: 1 Affects addresses from 192.0.1.1 through 192.0.1.254 using the 255 “wildcard” network address segment.
Event Logging Server Configuration 4.7.2.1 Using the Security Table There are two basic rules for checking a TCP/IP connection for legality. First, a more specific rule takes precedence over a less specific one. For example, if connections to 192.0.1.255. are disabled but connections to 192.0.1.78 are enabled, a connection to 192.0.1.78 will succeed. Second, in the absence of any rule that restricts a connection, access is allowed.
Server Configuration Event Logging VMS Ensure that the ets$configd process is running. Ensure that the priority level *.notice is defined in the syslog.conf file. UNIX Set up the logging facility on the host. See the syslog man pages for more information. Novell Using the PCONSOLE utility, add the ETS name as a printserver. Note: See Chapter 8 for more information on NetWare and PCONSOLE. 4.8.
5: Ports All Lantronix products have two types of ports: physical and virtual. ◆ There is one physical port for every serial or parallel connector on the ETS. Physical ports are numbered starting with 1. Devices connected to the physical ports are governed by characteristics set up for the individual ports with the Set/Define Ports commands explained in this chapter. ◆ There is one virtual port on every ETS.
Port Commands Ports Before a user can Telnet from the network to a ETS port and dial out using an attached modem, the port must be set for dynamic or remote access. To log into a port locally and Telnet to a remote host, set the port for local or dynamic access. To configure port access, use the Define Port Access command. Access must be configured with Define commands since the configuration is reset to the saved values every time a user logs in or connects to a service on that port.
Ports Port Commands Note: The ETS and the device with which it is communicating must agree on the type of flow control used. 5.1.2.2.1 Hardware Flow Control (RTS/CTS) When hardware flow control is used, the flow of data is controlled by two serial port signals (typically RTS and CTS). Two connected devices will assert and de-assert RTS and CTS to indicate when they are ready to accept data. For example, the ETS will assert RTS when it is ready to accept data.
Port Commands Ports Refer to Flow Control on page 5-2 for a description of the different flow control methods. Choose the method that’s most compatible with the serial device and applications you’ll be using. 4 Configure Flow Control Configure your serial device to use the selected method of flow control. Refer tothe device’s documentation for instructions. Configure flow control on the ETS using the Set/Define Port Flow Control command. Figure 5-8 displays an example.
Ports Port Commands To specify a preferred Telnet host, use the Set/Define Port Preferred Telnet command. Figure 5-12: Specifying a Preferred Telnet Host Local>> DEFINE PORT 2 PREFERRED TELNET 192.75.1.0 Environment strings can be added to the commands to specify additional connection information for a preferred connection. The following example tells the ETS to use the remote host’s FTP port (port 21) for the connection, and to use Passall mode.
Modems Ports Each virtual port is created with a default set of characteristics. The Set/Define Port commands (starting with Define Port Access on page 12-27) can be used to customize a virtual port during the Telnet/Rlogin session; however, these customizations cannot be saved. The port reverts to the default set of characteristics once the session is closed.
Ports Modems 1 The modem and ETS wait for a connection. The ETS provides DTR to the modem so that the modem will accept any incoming calls. The modem does not provide DSR to the ETS since it is not connected via the phone line. 2 The modem receives a call, asserts the Ring signal, and then asserts Carrier Detect (CD) to signal it accepted the connection. 3 The ETS sees its DSR input signal go high when the modem asserts DSR and/or CD.
Modems Ports 5.2.2.1 DSR (Data Set Ready) for Automatic Logouts An ETS port can be configured to automatically log itself out when DSR is no longer asserted; in other words, the port logs out when the modem is disconnected. This can help ensure port security because users are prevented from unplugging terminal lines and using sessions that are still active. 5.2.2.2 DSR for Controlling Remote Logins The DSR signal can also be used to determine whether or not a remote login to a port will be permitted.
Ports Modems Ports that support V.32bis should be set to 19200 baud. Also, ports that use compression should be set one or two speeds higher than the modem’s speed. For example, a port supporting a 2400 baud modem with compression should be set to 4800 or 9600 baud. 2 Use the autobaud feature of the ETS; the ETS will adjust its speed to that of the modem. Flow control isn’t strictly required in this configuration.
Modems Ports 5.2.7 Modem Configuration Checklist These items should be verified after any modem configuration. Note that some options might not be provided on the modem in question. ◆ The modem must disconnect immediately when DTR is dropped. ◆ The modem must assert CD (or DSR, if connected) when connected to another modem and must not assert CD when disconnected. The modem may optionally assert CD during outbound dialing.
Ports Other Port Characteristics Dial into the ETS again. The port should have been reset, and should no longer be connected to the network host. If not, the modem is incorrectly asserting DSR/CD, or there is a wiring problem. If outbound calls are to be supported, connect to the modem’s service with the Connect command. In many cases the Connect Local command is a quick shortcut: dial a remote modem. After the modem connects, log into the remote system.
Other Port Characteristics Ports 5.3.3 Device Type The Type characteristic specifies the device types compatible with a particular port. Type can be one of the following: ANSI, Hardcopy, or Softcopy. To set a type, use the following command: Figure 5-19: Configuring the Device Type Local> SET PORT 3 TYPE ANSI The command above specifies that the port is compatible with VT100-type devices. For further explanation, see Set/Define Port Type on page 12-54. 5.3.
Ports Other Port Characteristics 5.3.7 Port Messages Various degrees of “verbosity” are available for ports receiving ETS messages. Messages from other users on the ETS can be enabled or disabled with the Broadcast flag. If the serial line connecting a terminal to the ETS is an unsure connection, setting Loss Notification will cause an audible beep if a character is lost.
Security Ports 5.4 Security Between the various password protections on the ETS and the access control provided by service groups, security should not be a problem; almost any access restriction can be enforced. For ports that need a higher level of security, the Set/Define Port Security command allows the ETS manager to restrict a port user’s actions on the ETS. Ports set this way are called secure ports.
Ports Security Each Set Menu command takes three parameters: an entry number to determine its place in the menu, an option name that the user will see in that command slot, and the command string that will be executed if the user selects that entry. For example, the command displayed in Figure 5-28 will put an entry in menu position five.
Security Ports 5.4.5 Automatic Logouts Ports can be configured to log out automatically when the DSR signal is dropped to prevent users from accessing other sessions by switching physical terminal lines. Ports can also be configured to log out automatically or when they’ve been inactive for a specified period of time. 5.4.5.1 DSRlogout When a device connected to the ETS is disconnected or powered off, the DSR signal is dropped.
Ports Security If the Dialback call should fail for any other reason before the 80-second timeout (for example, if the number dialed is busy), a second caller may be able to log into the ETS. This possibility can be virtually eliminated by two steps: 1 In the Dialback string itself, issue a command to ignore incoming calls. An example of this command is ats0=0dt555-1234. 2 Re-enable incoming call answering after the DTR signal is dropped (that is, after the dialback session has ended).
6: Using the ETS A connection to a service or host is called a session on that host. One of the most useful features of the ETS is that it allows you to have multiple sessions on different hosts, and gives you easy access to all of them. Active sessions can include LAT, Telnet, or Rlogin connections, or any combination of the three. This chapter explains interactive sessions on the ETS.
Configuring Your Port Using the ETS You may remain logged into the ETS (with or without active sessions) perpetually, with a few possible exceptions. ◆ If you leave connected sessions for long periods of time, a host may log you out. Many hosts are set to log off users after a set period of inactivity; this will not affect your login to the ETS, but you will have to log into the remote host again. ◆ The ETS supports an inactivity logout timer of its own.
Using the ETS Connecting to Services ◆ Authorized Groups configures all the service groups the port can possibly use. Use the Set/Define Port Authorized Groups command to specify which of the Authorized groups are actually enabled. ◆ Autobaud lets the ETS attempt to automatically set the port’s speed and parity based on the first characters typed at login (they must be Returns). Autobaud works if the port is at least 1200 baud and is using eight bit characters, or seven bit characters with even parity.
Connecting to Services Using the ETS You can also force a connection to an explicit host and specify exactly which port (if applicable) to use on that host. This may be necessary because more than one host on a local network can provide a service. For example, the following command will attempt to connect to the printer service on a specific port of host vax8.
Using the ETS Connecting to Services If necessary, you can specify a login to an explicit port on the remote host by adding :xxxx to the end of the hostname or IP address. For example, the following command attempts a Telnet connection to TCP port 2005 on the specified host, rather than the default Telnet port. Figure 6-5: Specifying a Port Number Local> TELNET 192.0.1.90:2005 On some Telnet connections, padding of Newline characters may be a problem.
Default Services Using the ETS 6.3.5 Connecting to the Server from UNIX Hosts If incoming TCP/IP logins are enabled (again, see the Set/Define Server Incoming command), users can log into the ETS from another UNIX host. They can also use Rlogin to connect to a LAT or TCP/IP service offered by the ETS. To log into the ETS using Telnet, type either of the following commands at the UNIX prompt where IP_address is the address of the ETS and etsname is the name of your ETS.
Using the ETS Session Management You can specify Telnet services as either text names or numeric IP addresses. TCP/IP hosts on a network are unique across the network, so there is no need to differentiate Telnet nodes with the Node and Destination parameters. A default Telnet service is different from a default LAT service.
Local Server Commands Using the ETS Pressing the Backward or Forward switch key is identical to going back to Local mode and typing the command explicitly. However, the switch keys also function in Local mode—if you press the defined Forward key from the local prompt, it is the same as typing Forwards as a command. Unlike the Break key, Forwards and Backwards are not assigned to any particular key by default. They must be explicitly configured.
Using the ETS Status Displays If you do not want to receive broadcast messages, you can enter Set Port Broadcast Disabled to refuse them on your own port. 6.6.2 Lock The Lock command can be used to disable access to your port without actually logging out. If you Lock your port, you will be asked for a password and a verification of the password; the latter is used to ensure that you typed the password correctly.
Status Displays Show Hosts Using the ETS Displays the TCP/IP hosts known to the ETS. These are hosts that were resolved with a connect attempt, seen with rwho broadcasts, or explicitly added to the host table with the Set/Define Telnet Hosts command. The Host, Node, and Service displays allow you to use “wildcards” in place of host names. Wildcards are characters that can be substituted for a single character or a series of characters.
Using the ETS Status Displays Show SLIP Shows current and default SLIP connection information, and packet counters for current SLIP sessions. Show SNMP Shows the SNMP community names and access types. Show Telnet Shows all of the current TCP/IP nodes that the ETS can see, including hosts listed in the host table, hosts learned through rwho broadcasts, and hosts resolved after Connect/Telnet requests. Show Users Displays the users on the ETS.
7: TCP/IP Host Setup The EZWebCon configuration software is the easiest way to configure teh Server. See your Installation Guide for more information on using the EZWebCon software. Servers servicing TCP/IP print queues must have the TCP/IP protocol enabled (the default). To verify that TCP/IP is enabled, enter the List Protocols command. The server must have an IP address before configuration; see your Installation Guide for more information.
LPR Printing RTEL TCP/IP Host Setup Lantronix supplies RTEL host software, which requires installation and configuration on the host but provides more functionality than remote-LPR. It allows the host’s lp or lpr printing system to transparently use the ETS print devices, and also allows the creation of named pipe devices on the host that map to the ETS’s ports. The RTEL backend filter interfaces with the host-based spooling system. It receives data from the spooling system and sends the data to the ETS.
TCP/IP Host Setup LPR Printing 7.2.1 LPR Basics LPR is supported on many machines. To create a print queue, 1 Add the host print queue name into /etc/printcap. 2 Specify the remote node name (the host name of the ETS) and the ETS service. Note: There are slight variations in LPR configuration for AIX, HP, SCO UNIX, Solaris, and Windows NT hosts; after reading this section, refer to the following sections for platform-specific configuration information.
LPR Printing 5 TCP/IP Host Setup Print to the queue using normal lpr commands. Figure 7-4: Printing from a BSD system % lpr -PETS_PRT /etc/hosts 7.2.2 LPR on Windows NT 3.5.1 (and later) This section assumes that TCP/IP, Simple TCP/IP, and Microsoft TCP/IP printing have been installed on the Windows NT host. 1 In the Control Panel, double-click the Printers icon. 2 Double-click the Add Printer icon. 3 In the window that appears, choose My computer and click Next.
TCP/IP Host Setup 5 LPR Printing Select LPR Port. Note: If LPR Port is not an option, refer to your Windows NT documentation for instructions on installing the Microsoft TCP/IP Printing service. 6 Enter the name or IP address of your ETS on the first line, and enter the name of your ETS print service on the second line. 7 Select the manufacturer and printer type. 8 Enter the queue name.
LPR Printing 9 TCP/IP Host Setup If applicable, choose Shared and select the type of operating system that the printer will be working with. (First confirm that the print queue is working.) 10 Test the printer by choosing Yes and clicking Finish. 7.2.3 LPR on AIX Hosts LPR is available on machines running IBM’s AIX operating system versions 3.2 and higher. Print queues on AIX hosts can be configured using either UNIX commands or the System Management Interface Tool (SMIT) application. 7.2.3.
TCP/IP Host Setup LPR Printing The device name is simply the queue name with a “d” added. Print to the queue using normal lp syntax. Figure 7-6: Printing to a Queue % lp -dETS_PRT filename 7.2.3.2 Using SMIT The System Management Interface Tool (SMIT) allows you to enable LPD printing and create print queues. 1 At the host prompt, type SMIT. 2 From the main window in the application, choose Print Spooling. 3 Choose Manage Print Server and Start the Print Server Subsystem (lpd daemon).
LPR Printing TCP/IP Host Setup 7.2.4 LPR on HP Hosts LPR is supported in HP/UX versions 9.0 and greater. Print queues on HP hosts can be configured using either UNIX commands or the System Administration Manager (SAM) application. 7.2.4.1 Using UNIX Commands To configure and use a print queue using LPR: 1 Become the superuser.
TCP/IP Host Setup 1 LPR Printing Ensure that the Berkeley remote printing files and executable programs are installed on the host machine. If not, issue the mkdev command to install them. Figure 7-8: Installing Print Files # mkdev rlp The mkdev rlp command should only be installed once. If it is used repeatedly, serious problems will result with the machine. Note: 2 Create the remote printer using the following command.
Reverse Telnet (RTEL) Note: TCP/IP Host Setup Due to problems in the Solaris queueing system, LPR is not reliable on Solaris machines. Users with Solaris hosts should use the RTEL software provided by Lantronix. 7.3 Reverse Telnet (RTEL) If LPR is not adequate for an application (for example, if banners are needed before jobs or more flexibility is needed in printing), the supplied RTEL software can be configured on the host.
TCP/IP Host Setup 2 Reverse Telnet (RTEL) Set your current directory to the RTEL directory. Figure 7-12: Restoring RTEL software # mkdir /tmp/rtel # cd /tmp/rtel # tar xvf /cdrom/products/servers/rtelv4_2_2/rtel_src.tar Note: The word “cdrom” in the example above should be replaced with the name of the current distribution CD-ROM. For MS-DOS, the source code will be in a single tar archive file (rtel_src.tar). This file contains all of the source code, but does not contain any executables.
Reverse Telnet (RTEL) TCP/IP Host Setup When multiple print queues (possibly on more than one host) point to the same ETS queue, the hosts will provide local queueing, but you may still have multiple jobs attempting to access the ETS. In this case, the ETS will provide queueing among the hosts. Jobs from multiple hosts are handled in order, regardless of size or priority. This may explain why a particular host’s queue seems to stop for an extended time.
TCP/IP Host Setup Reverse Telnet (RTEL) Figure 7-14: Installing the Backend Filter # cd /usr/spool/rtel # ./mkprt Installing a print queue requires root privileged. Do you want to continue the installation [yes] Please enter the name of the print queue to create: hp4 A printcap entry for hp4 needs to be created.
Reverse Telnet (RTEL) TCP/IP Host Setup Table 7-1: Print Options, cont. Note: Option Functionality Formfeed Formfeeds (ASCII 0xC, Ctrl-L) are appended to the end of the job. This option should not be used with the PostScript or Binary options. None No options are enabled Postscript A Ctrl-D (ASCII 4) is used to terminate a print job, rather than the standard formfeed (ASCII 12). Options must be specified in lowercase characters; multiple options can be specified separated by commas.
TCP/IP Host Setup Reverse Telnet (RTEL) The command line parameters will be verified when the RTELPD daemon is started. The daemon process will then wait for input to arrive on the pipe device. When input data is detected, a connection attempt will be made to the target terminal server port, and if it is successful, data will start moving through the path. If the specified service or port is currently busy, the daemon process will wait until the service or port is available and then try again to connect.
Reverse Telnet (RTEL) Note: TCP/IP Host Setup See the supplied RTELPD man page for a complete list and description of the RTELPD options. Figure 7-17: Installing the RTELPD Daemon Process # cd /usr/spool/rtel # ./mkpipe Installing a pipe device requires root privileges. Do you want to continue the installation [yes] This install script will create a named pipe as the interface to the RTEL software. This pipe will be used as the output device for your printing system.
TCP/IP Host Setup Reverse Telnet (RTEL) 7.3.6 Creating a BSD Print Queue Using RTELPD To create a generic BSD print queue using the RTELPD pipe daemon, 1 Create a named pipe as shown in Figure 7-17. 2 Edit the /etc/printcap file and insert an entry in the following form to create a simple queue. Figure 7-19: Editing the /etc/printcap File rtel_prt:\ :lp=/dev/rtp1:| :sd=/usr/spool/lpd: Note: 3 See the RTELPD man pages for specific examples of configuring a print queue for each supported system type.
TCP Socket Connections TCP/IP Host Setup 7.3.8 RTEL Troubleshooting The job_status diagnostic file in the /usr/spool/rtel directory may help locate problems. The file contains any errors that occurred on a particular print job, such as job aborted, invalid service name, and so on. This file should be examined if the RTEL queue is not performing correctly.
TCP/IP Host Setup PostScript Configuration 7.5 PostScript Configuration To print PostScript jobs, you must enable the PostScript attribute on the service being used. Figure 7-22: Enabling the PostScript Attribute Local>> DEFINE SERVICE ETS_P1 POSTSCRIPT ENABLED A very common problem when printing PostScript jobs from UNIX queues is including non-PostScript data, such as header or banner pages, as part of the job. When printing from a UNIX host machine, verify that header and trailer pages are not sent.
8: NetWare Host Setup NetWare print queues may be configured using PCONSOLE or QINST, which are both provided on the distribution CD-ROM. The method that you use to set up print queues will be determined by the version of NetWare that you are using and whether you use Bindery Emulation or NetWare Directory Services (NDS). If you are running NetWare version 4.0 or greater, refer to the Creating NDS Print Queues with PCONSOLE section. If you are running versions 2.x, 3.x, or version 4.

9: LAT Host Setup The EZWebCon configuration software is the easiest way to configure the ETS. See your Installation Guide for more information on using the EZWebCon software. Note: A LAT license number, which can be obtained from your dealer or Lantronix, is required for all multi-port server units. You will not be able to use LAT functionality until you enter the license number and reboot the unit. Servers servicing LAT print queues must have the LAT protocol enabled (the default).
Printing from LAT LAT Host Setup To create and start a LAT queue using a LAT application port, enter the following command. Figure 9-2: Creating and Starting the Queue $ INITIALIZE/QUEUE/START/ON=LTAnnnn:/PROCESSOR=LATSYM/RETAIN=ERROR queue_name A print request would look like this: Figure 9-3: Print Request $ PRINT/QUEUE=queue_name filename.txt To connect to the Server service from the VMS host, use a command similar to the following: Figure 9-4: Connecting From VMS Host $ SET HOST/DTE lta45 9.1.1.

Technical Support is also available via Internet email at support@lantronix.com. A.
B: Troubleshooting Before troubleshooting your ETS, ensure that all physical connections are secure. Refer to the Installation chapter of your Installation Guide for connection instructions. Your Installation Guide may also contain additional troubleshooting information. Many unexplained errors are the result of having duplicate IP addresses on the network. Ensure that your ETS has a unique IP address before proceeding.
BOOTP Troubleshooting Troubleshooting B.3 BOOTP Troubleshooting If the BOOTP request is failing and you have configured your host to respond to the request, check these areas: Table B-3: BOOTP Troubleshooting Area to Check Explanation BOOTP is in your system’s /etc/services file BOOTP must be an uncommented line in /etc/services. The ETS is in the loadhost’s /etc/hosts file The ETS must be in this file for the host to answer a BOOTP or TFTP request.
Troubleshooting Modem Configuration Checklist Most modem problems are caused by cabling mistakes or incorrect modem configuration. However, the following items should be verified after any modem configuration, and re-checked when there is modem trouble. ◆ Set the modem to disconnect immediately when DTR is de-asserted. ◆ Set the modem to assert CD (or DSR, if connected) when connected to another modem. It must not assert CD when disconnected. The modem may optionally assert CD during outbound dialing.
C: Updating Software Current software files (ETS*.SYS) are available on the distribution CD. Software updates and release notes for the ETS can be downloaded directly from the Lantronix development systems via the Lantronix World Wide Web site (www.lantronix.com), or via anonymous FTP through the Internet (ftp.lantronix.com). C.1 Obtaining Software C.1.1 Via the Web The latest version of ETS*.SYS can be downloaded from the Lantronix Web site.
Reloading Software Updating Software To log into the FTP server, enter a username of anonymous and enter your full email address as the password. The following text will be displayed: Figure C-1: Sample FTP Login 230-Welcome to the Lantronix FTP Server. 230230-IMPORTANT: Please get the README file before proceeding. 230-IMPORTANT: Set BINARY mode before transferring executables. 220230-Direct questions to support@lantronix.
Updating Software Reloading Software Downloading and rewriting the Flash ROM will take approximately two minutes from the time the Initialize command is issued. If the download file cannot be found or accessed, the ETS can be rebooted with the code still in Flash ROM. The OK/ACT LED will blink quickly while the ETS is booting (and reloading code) and then slowly when it returns to normal operation.
Troubleshooting Flash ROM Updates Updating Software C.2.1.3 MOP The ETS*.SYS filename is the only parameter that the ETS needs to reload via MOP. Make sure the service characteristic is enabled on the host’s Ethernet circuit, copy the ETS*.SYS file to the MOM$LOAD directory, and reload the ETS using the Initialize Reload command. Note: If an error message is displayed indicating an invalid record size on the VAX console, re-transfer the ETS*.SYS file in binary mode. C.
Glossary AppleTalk AppleTalk was developed by Apple Computer to allow networking between Macintoshes. All Macintosh computers have a LocalTalk port running AppleTalk over a 230kbit serial line. AppleTalk also runs over Ethernet media (via EtherTalk) and Token Ring network media (via TokenTalk). Due to dynamic addressing and powerful name directory services, installing an AppleTalk device is generally as simple as attaching it and turning it on. ARP Address Resolution Protocol.
console Glossary the IP address of a load host (usually itself), and the name of the download file. The dumb node needs only know its own hardware address, as this is what the BOOTP server uses to decide whether it can help the node and what information to provide. BOOTP implementations usually have a configuration file (such as /usr/etc/bootptab) that lists the hardware and IP addresses of BOOTP clients, as well as the download file they should use.
Glossary gateway gateway A TCP/IP host that can access two or more different Ethernet networks. As such, it can forward messages across networks that other hosts would not be able to access. The host generally has multiple IP addresses, one for each network. For example, a gateway might “live” at addresses 192.0.1.8 and 193.0.1.8. Hosts wishing to forward messages may address the messages to the gateway which will then pass them on to the other network. For example, if an ETS at address 192.0.1.
LAT LAT Glossary Local Area Transport. LAT is a Digital Equipment Corporation proprietary network communication protocol. The protocol is based on the idea of a relatively small, known number of hosts on a local network sending small network packets at regular intervals. LAT will not work on a wide area network scale as TCP/IP does, as it cannot distinguish large numbers of nodes. For local networks, however, LAT is usually faster and less prone to pauses than TCP/IP.
Glossary MTU MTU Maximum Transmission Unit. The MTU of a link is the maximum packet size, in bytes, that can be transmitted across the link. For Ethernet, this is 1536 bytes. For SLIP lines, it can be variable, based on each host’s ability to receive and reassemble packets. The RFC for SLIP suggests an MTU of 1006 bytes, but this is not a requirement. multicast A message that is sent out to multiple devices on the network by a host.
PostScript Glossary PostScript A printer/display protocol developed by Adobe Corporation. PostScript is actually a printing and programming language used to display text and graphics. Unlike line/ASCII printers, which print character input verbatim, PostScript printers accept an entire PostScript page, and then interpret and print it.
Glossary ROM ROM Read-Only Memory. This kind of memory device retains its information even when its power source is removed. A ROM version of the ETS does not need to download code, since it carries the entire executable code in ROM. Frequently the ROM is provided as flash ROM, which can be reprogrammed if the software needs to be updated. router Hosts on large networks that are connected to more than one network and route messages to the correct destination nodes.
session session Glossary Any connection to a network service. The network service can be an interactive login to a LAT or TCP/IP host, a connection to a modem on the Server or another server, or something else. Users on the Server can have more than one session active at one time, allowing them to quickly switch between hosts or connections. Sessions are kept in a list, and can be switched with the Forward and Backward commands. They can be listed with the Show Session command.
Glossary tap tap A point on the network backbone where other devices can be attached. If the network is thought of as a freeway, the taps on the network are the on and off ramps to the freeway (and like freeway access ramps, taps are usually where network problems occur). Taps may be of several types, including simple “T” connectors or “Vampire” taps that attach directly to a network cable. TCP/IP The standard network protocols in UNIX environments. They are almost always implemented and used together.
transceiver Glossary transceiver The physical device that interfaces between the network and the local node. When talking about networks, the term transceiver generally refers to any connector that actively converts signals between the network and the local node. An example of a transceiver is a MAU. TSM Terminal Server Manager. TSM is a software package that allows terminal servers on a network to be remotely managed from another node.
