1: Introduction 1.1 Product Overview The Lantronix Print Servers (EPS, MPS, and LPS models) are multi-protocol print servers that provide shared network access to printers for a variety of network protocols and operating systems. The print servers generally support the TCP/IP, IPX (NetWare), and Local Area Transport (LAT), AppleTalk (EtherTalk), and Microsoft LAN Manager protocols. They can queue multiple pending jobs and service those jobs in the order in which they are received from hosts.
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 Server are not nodes.
Introduction Server Features Easy Configuration The EZWebCon utility (provided on CD-ROM) allows users to configure the Server from a any host machine running the Java Virtual Machine (JVM). Note: You must be Supervisor to run the EZWebCon utility on a NetWare client.
How To Use This Manual Introduction ❍ Automatic session logouts when a port is disconnected or a device is turned off. ❍ Password protection for privileges, ports, services, maintenance commands, and the remote console. DHCP Support The Server can obtain an IP address from a DHCP server at boot time. SNMP Support The Server supports the Simple Network Management Protocol (SNMP), which can be used by network managers to monitor network load and error conditions.
2: Concepts 2.1 Services Services are the basic method of connecting to the Server from any host or another server. In general, a service is required on the Server before any job or connection queueing will take place. See the Server Configuration chapter for details on creating and using services. 2.2 Network Protocols A network protocol describes the data contained in Ethernet packets. The network protocols provided by the Server are completely separate, other than the use of the Ethernet data layer.
AppleTalk Concepts The Server supports only the Printer Access Protocol (PAP) and therefore cannot create outgoing AppleTalk sessions—only incoming print requests are accepted. Any services on the Server with AppleTalk enabled will show up as LaserWriters in Macintosh Chooser windows and are associated with an available zone (explained in Section 2.3.2).
Concepts LAN Manager 2.3.3 Name Binding Protocol (NBP) NBP is used by AppleTalk to advertise resources, such as printers and fileservers, to the network. Any resource that other users can access will have NBP information that must be communicated to other nodes. The items in the Chooser window reflect the NBP resources on the network. NBP and the Chooser organize resources by three levels: name, type, and zone. Names are arbitrary strings assigned by users, such as Kathy or MyPrinter.
LAT Concepts 2.5 LAT Digital Equipment Corporation’s LAT (Local Area Transport) networking software is designed to ease the process of accessing and managing local area networks. LAT is significantly different from other protocols in two important ways. First, LAT is not routable. There is no way to divide LAT networks into smaller subnetworks and use routers to reduce traffic between nodes. Second, LAT is a timer-driven protocol.
Concepts TCP/IP LAT multicast messages contain a rating for each service offered. Ratings range from 0 to 255; 0 means the service is unavailable, while 255 means the service is available and has no current users. Ratings for a given service may change over time. For example, the rating for a computer accepting logins will generally change as its workload changes. Conversely, ratings for a modem are typically either 0 (in use) or 255 (not in use).
TCP/IP Concepts A unique IP address must be specified on the Server before any of the TCP/IP functionality is available. See your Installation Guide for more information on configuring the IP address. A DHCP server can be used to temporarily assign a leased IP address to the Server. See Dynamic Host Control Protocol (DHCP) on page 12-6 for more information. 2.6.
Concepts TCP/IP The Server will respond to queries for unknown MIBs with a “not in MIB” error to the requesting host. RFC’s 1065, 1066, and 1098 offer additional information on SNMP queries and the structure of the MIBs. See Set/Define SNMP on page 12-61 for more information about configuring MIB usage. Traps are sent to a host when an abnormal event occurs on the Server. The Server can generate limited forms of three SNMP traps.
NetWare Concepts Note: To see a list of Server processes, enter the command “finger finger.” Netstat Displays the status of the routing tables and current network sessions. Ping Sends a TCP/IP request for an echo packet to another network host to test network connections. 2.7 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.
Concepts PostScript 2.7.2 Access Lists Since NetWare networks can have hundreds of fileservers, the network needs a way to reduce the number of Server queries, both to reduce network traffic and to prevent long delays in servicing active queues. By using access lists (created with the Set/Define Protocols NetWare Access command on page 12-31) you can control which file servers the Server will and won’t poll for print jobs.
Security Concepts 2.9 Security Several methods can be used to control access to the Server and restrict user behavior once logged in. For example: ◆ 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 Server. ◆ Ports used for network logins can be “preconfigured” with a standard set of characteristics for each login.
3: Getting Started This chapter provides background information to get you started using the Server. Topics include methods used to initially set up the Server as well as ongoing maintenance issues, such as rebooting and restoring factory default settings. This chapter assumes the following: ◆ The Server has booted properly and is running its operational code ◆ The Server is connected to the Ethernet ◆ For IP network users, the Server 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 Server using a standard web browser with JavaScript enabled. Simply type the Server 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 Server, 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, Server 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 All keys used for entering and editing commands are listed in Table 3-1. Table 3-1: Command Line Editing Keys Note: Key Purpose Return Executes the current command line Delete Deletes the character before the cursor Ctrl-A Toggles insert mode (insert or overstrike; overstrike is the default).
Getting Started Save Abbreviating Keywords Makes a group of commands entered with the Set command permanent. For example, users can enter several Set commands to configure a service, then Save the service. Settings that are made with both Set and Save behave as if they were configured using Define commands. See Save on page 12-11 for more information. Note: Define Makes a permanent change that generally doesn’t take effect until the unit is rebooted.
Maintenance Issues Getting Started 3.6.1 Changing the Server Name The Server is initially configured with a server name. However, you can give the Server a custom name of up to 16 alphanumeric characters using the following command: Figure 3-5: Changing the Server Name Local>> DEFINE SERVER NAME “PrintServer” The Server name string must be enclosed in quotes if lowercase letters are used.
Getting Started Editing the Boot Parameters 3.6.4 Restoring Factory Defaults Should it become necessary, the Server can be restored to the default settings installed at the factory. This will restore everything—the Server 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.
System Passwords ◆ Getting Started NetWare fileserver name Boot parameters are edited with Set/Define Server commands. Figure 3-10: 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 Server: 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 Server, translate this information into a series of commands, and save the commands in a file. This file can be downloaded to configure the Server. 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 Server 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 Server 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 Server 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 Server to communicate on the network: the Server’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 Server, 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 Server 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 Server 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 Server to rescan all fileservers for pending jobs.
Creating Services Server Configuration 4.5.3 Host Limit The Set/Define Server Host Limit command is used to set the number of remote TCP/IP hosts for which the Server will store information. In large network environments, this will keep Server network overhead down. The host limit applies only to hosts that were not explicitly set in the host table (for example, hosts seen using rwho). Figure 4-13: Setting a Host Limit Local> DEFINE SERVER HOST LIMIT NONE 4.
Server Configuration Creating Services 4.6.1 Creating a Simple Service (A Line Printer) Connections, queueing, banner, and formfeed options are enabled by default when you enter a Set Service command, so it is not necessary to configure them explicitly. NetWare, and RTEL access are provided by default, but LAT and AppleTalk access have to be explicitly enabled. The port providing the service must also allow remote access, so it must have access set to Dynamic or Remote.
Creating Services Server Configuration 4.6.2 Setting Up a Service With Group Codes Local ports can be given a list of LAT service groups that they are authorized to use. The access list will deny the ports access to services that do not belong to any matching authorized groups. For example, you may wish to limit connections to a printer or to a certain set of ports on a server.
Server Configuration Creating Services 4.6.4 Enabling Other Service Options In addition to TCPport and Telnetport, several other service options can be enabled on a service: Table 4-1: Service Options Option Function AppleTalk Enables or disables AppleTalk access to the service. Macintosh computers, for example, will see the service name in their Choosers if they are on the same zone/network as the Server.
Security Server Configuration 4.6.5 Setting Up a Modem Service The example displayed in Figure 4-18 is rather detailed, but once you have created a service or two, the process should become largely intuitive. Remember that the Show/Monitor/List Services commands are available to show you exactly what has been set up so far. If you are unsure or think you may have made a mistake, delete the service (using Clear/Purge Service) and start from scratch.
Server Configuration Security 4.7.1 Controlling Incoming Sessions The Set/Define Server Incoming command allows or denies incoming LAT or Telnet connections. It can also require incoming users to enter the Server login password to log in from the network. The following commands allow LAT and Telnet users to log into the Server without having to enter a password.
Security Server Configuration The IP address must be four segments of 0-255 each. A 255 in any segment applies to all numbers in that range such that 192.0.1.255 includes all addresses of 192.0.1.n. A trailing zero in any address is shorthand for “all addresses in this range are disabled, for both directions and for all ports.” The following two commands are equal. Figure 4-22: Set IPsecurity Command Local> SET IPSECURITY 192.0.1.0 Local> SET IPSECURITY 192.0.1.
Server Configuration Event Logging 4.7.3 SNMP Security Since SNMP can be used to change Server settings, a way to prevent unauthorized Set commands is needed. The Server provides a security mechanism for restricting SNMP access to the unit that is linked to the SNMP community name used. To prevent easy access to the allowed community names, the Show SNMP and List SNMP commands are restricted to privileged users.
Event Logging CONSOLE Server Configuration Indicates events should be logged to the Server serial console port (designated as port 1). 4.8.3 Event Classes The event classes that can be logged are: Commands All commands issued on the Server will be reported (verbose output). Network All users logging in from or out to the network will be reported. Printer Changes in printer status lines will be reported. Security All logins and Set Privileged events are reported, as well as any password failures.
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 Server. 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 Server.
Port Commands Ports 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. Figure 5-3: Configuring Connection Type Local>> DEFINE PORT 2 ACCESS DYNAMIC If a connection to a service is failing, check the port’s access mode first. 5.1.
Ports Port Commands 5.1.2.2.2 Software Flow Control (XON/XOFF) XON/XOFF controls the flow of data by sending particular characters through the data stream. The characters sent to signify the ability or inability to accept data are Ctrl-Q (XON) and Ctrl-S (XOFF).
Port Commands Ports For more information about flow control command syntax, see Set/Define Port Flow Control on page 12-19. 5.1.2.3 Parity, Character Size, and Stop Bits The default character size of 8 data bits can be changed to 7 data bits. Similarly, the default stop bit count of 1 bit can be changed to 2 bits. Parity is normally None, but can also be Even, Mark, Odd, or Space.
Ports Other Port Characteristics 5.2 Other Port Characteristics 5.2.1 DTRwait The DTRwait flag governs whether a port provides DTR when idle. [[[Normally DTR is always asserted. In general, this allows modems to answer an incoming call, as many modems will not answer a call unless DTR is asserted.]]] If you enable DTRWait, the Server will deassert DTR until the port receives a connection request.
Security Ports 5.3.2 Preventing Access Until DSR Is Asserted The Signal Check characteristic can be used to prevent remote connections to a port unless DSR is asserted. This is often used to prevent Telnet logins to a port until the device attached to the port (for example, a terminal) asserts the DSR signal, indicating that it is connected and powered on. Figure 5-14: Enabling Signal Check Local>> DEFINE PORT 3 SIGNAL CHECK ENABLED 5.3.
6: Using the Server 6.1 Logging In and Out 6.1.1 Logging In Each port on the Server can support a device such as a printer. Use the following steps to log into the Server: 1 Telnet into the Server. 2 If the Server manager has enabled password protection you will see the words Login Password>. Type the login password and press the Return key. 3 If this port has no permanent username associated with it, the Server will respond with Username> .
Local Server Commands Using the Server ◆ Access controls whether the port is accessible to local equipment (Local), remote users such as a local printer or dial-out modem (Remote), or both (Dynamic). Dynamic access is used for dial-in/dial-out modems, or for devices such as teletypes that can be used both interactively and as print devices. ◆ Name sets the port’s name for identification purposes (not to be confused with the username, which identifies who is using the port).
Using the Server Status Displays Show Ports Shows the current setup of your port. Settings such as flow control, parity, default preferred hosts, and username are shown, as well as enabled settings. The display will also show printer status: either on-line and ready to accept jobs, or in a non-ready state such as ACK, Busy, or Error. Show Protocols Shows an overall view of the network protocol counters, unless a parameter is added to the command.
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 Server print devices, and also allows the creation of named pipe devices on the host that map to the Server’s ports. The RTEL backend filter interfaces with the host-based spooling system.
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 Server) and the Server 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 -PServer_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 Server on the first line, and enter the name of your Server print service on the second line. 7 Select the manufacturer and printer type.
LPR Printing TCP/IP Host Setup 8 Enter the queue name. 9 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.
TCP/IP Host Setup LPR Printing 7.2.3.1 Using UNIX Commands Using LPR on AIX hosts involves a slightly different configuration procedure. The queue configuration file is /etc/qconfig and the format of the entry is different, as shown in the example below. Note the lack of colons (:) and the required white space.
LPR Printing TCP/IP Host Setup 5 From the next dialog box choose the desired type of remote printing. 6 Add the following information to the Add a Standard Remote Print Queue dialog box: A The name of the print queue to add B The name of the Server unit C The name of the Server service D The type of print spooler on the remote server, and E A description of the printer on the remote server. A dialog box will appear with the message “Added print queue.
TCP/IP Host Setup LPR Printing 1 At the HP prompt, type SAM. 2 From the main application window, choose Printers and Plotters. Click Open and choose Printers/ Plotters. 3 In the Actions pull-down menu, select Add Remote Printer/Plotter. 4 Enter the name of the print queue to add, the name of the Server unit, and the name of the Server service 5 Print to this queue using normal lp syntax (see Figure 7-6). 7.2.5 LPR on SCO UNIX Hosts LPR is supported in SCO V3.2 release 4 with TCP/IP versions 1.
Reverse Telnet (RTEL) TCP/IP Host Setup 4 When prompted for the queue name, enter the name of the service on your print server. To change the queue name at a later time, manually edit the printcap file. 5 Print to this queue using normal lp syntax (see Figure 7-6). 7.2.6 LPR on Sun Solaris Hosts The following commands configure a BSD print queue on a Solaris 2.3 system. These commands require that you are the superuser and in the bourne shell.
TCP/IP Host Setup Reverse Telnet (RTEL) The backend filter simply accepts data from the queue manager (LPD for BSD, lpsched for SYSV, and qdaemon on AIX) and moves that data over the network to the terminal/print server. The backend filter can perform simple reformatting of the job, such as tab expansion, to expansion, and banner pages. It cannot, however, perform complicated tasks such as PostScript conversion. See the RTELbackend man page for more information.
Reverse Telnet (RTEL) TCP/IP Host Setup Figure 7-13: RTEL Installation # ./lpinstall Installing the RTEL software package requires root privileges.
TCP/IP Host Setup 3 Reverse Telnet (RTEL) Execute the mkprt script. The following example illustrates the process on a BSD-type system. When it is completed, the queue (hp4) should be able to process requests. 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 The options area specifies which if any of the print options are enabled. The available choices are listed in Table 7-1. Table 7-1: Print Options Note: Option Functionality Banner A banner page is printed before each job. The banner will show the date, name of the job, and name of the user who requested it. Binary No Line Feed processing is performed. This is useful for non-text files (such as plotter or graphics files).
TCP/IP Host Setup Reverse Telnet (RTEL) 7.3.5 Setting up the RTEL Named Pipe Daemon The basic concept behind the RTELPD daemon is to allow a UNIX system to use its own output filter programs that provide special purpose post-processing and then write the data into a named pipe device. The RTELPD daemon will read the data from the pipe and send it out over the network to a terminal or print server port. Note: The output filter in this case is either provided by the host system or is custom software.
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 Server_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.
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.
Printing NetWare Host Setup B If you have email access, send email to nds-info@Lantronix.com. You will receive a blank registration form that can be completed and returned to Lantronix. C If you do not have Internet access, contact a Lantronix sales representative for assistance. Contact information is provided in Appendix A. 2 Enable NDS on the Server by entering theSet/Define Protocols NetWare DSLicense command along with the string that you received via step 1.
NetWare Host Setup Printing Pserver can also be configured manually via PCONSOLE on the file server(s). PCONSOLE is useful, for example, when you want to see exactly what is being configured by the QINST utility. Some basic familiarity with PCONSOLE is assumed in the examples. Rprinter is set up via the PCONSOLE utility on the file server(s). Again, basic familiarity with PCONSOLE is assumed in the examples. 8.3.
Printing NetWare Host Setup A Log in as Admin on the file server you will be changing and type PCONSOLE at the F: prompt to start the utility. B From the main menu choose Quick Setup. The Quick Setup window will appear. Enter the name of the Server, the name of the service used for printing, the name of the print queue, and any other necessary information at the prompts. Figure 8-7: Quick Setup Print Server: Server_xxxxxx New Printer: Server_xxxxxx_PCL New Print Queue: printq ...
NetWare Host Setup 2 Printing In the Directory Tree windows, navigate to and select the context in which you want to install the printer. Figure 8-8: Context Window 3 From the Menu Bar, select Tools: Print Services Quick Setup. Figure 8-9: Quick Setup Menu Option 4 In the Quick Setup dialog box, enter the necessary information. Figure 8-10: Quick Setup Dialog Box A In the Print Server Name field, enter the name of your Lantronix server.
Printing NetWare Host Setup 5 Click Create. 6 Print a test document using the new print queue. 8.3.3 Creating Bindery Print Queues with QINST The QINST utility is the recommended way to configure Bindery print queues.

9: LAT Host Setup The EZWebCon configuration software is the easiest way to configure the Server. 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.
LAT Host Setup Printing from LAT For example, if you want to create a new LAT device LTA1234 that accesses print service printer1 on the Server named server1 using VMS queue remote_prq, enter the commands shown in Figure 9-8. Figure 9-8: Creating LAT Device $ RUN SYS$SYSTEM:LATCP LCP> CREATE PORT LTA1234/APPLICATION LCP> SET PORT LTA1234/NODE=server1/SERVICE=printer1 LCP> EXIT The Server name must match the name in the /Node field in the LATCP Set Port command shown above.
Troubleshooting 2 LAT Host Setup Create the reset module (a file named a file named EOJ.TXT) using a text editor. Place a Ctrl-D in this file and insert it into the system device control library. Figure 9-13: Creating Reset Module $ library/replace sys$library:sysdevctl.tlb eoj.txt 3 If the system device control library does not exist, create it. Figure 9-14: Creating a Control Library $ LIBRARY/CREATE/TEXT SYS$LIBRARY:SYSDEVCTL.TLB 4 Enter the INIT/QUEUE command to create the queue itself.
LAT Host Setup Troubleshooting ◆ On your Server, verify that the server and port/service names specified match the names obtained via Show Port LTAnnnn, and ◆ If using a service, verify that the service is available by issuing the following Server command: Figure 9-17: Show Service Command Local> SHOW SERVICE service_name CHARACTERISTICS The service port should be the port to which the printer is physically connected. The service rating should be non-zero to signal that the service is available.

LAT licensing To use LAT you must obtain a LAT license from your dealer or from Lantronix. Then use the Define Protocol LAT License command on your Server.
10: AppleTalk Host Setup The EZWebCon configuration software is the easiest way to configure the Server. See your Installation Guide for more information on using the EZWebCon software. The following sections cover command line print configuration for AppleTalk hosts. Note: Macintoshes that do not support EtherTalk will need either an Ethernet card or a LocalTalk-to-EtherTalk router to use the Server 10.
Printing from a Macintosh AppleTalk Host Setup 10.1.2 Macintosh Service Configuration To print from a Macintosh: 1 Create a service and enable both AppleTalk and PostScript. Figure 10-3 shows a parallel service named mps_prt. Figure 10-3: Enabling AppleTalk and PostScript on a Service Local>> DEFINE SERVICE mps_prt APPLETALK ENABLED POSTSCRIPT ENABLED 2 Once you’ve created the service, it should be visible in the Chooser of any Macintosh that is in the same zone as the Server.
AppleTalk Host Setup Troubleshooting Macintosh Printing Files containing embedded bitmap graphics may not print correctly even if the text surrounding the graphics does. This is because the bitmaps are actually binary data in this case, and binary data cannot be printed via serial or parallel interfaces.

Bi-directional communication Lock the printer in PostScript mode and issue the Test Service PostScript Count n command. This sends a job to the printer and waits for the response.
11: LAN Manager Host Setup The EZWebCon configuration software is the easiest way to configure the Server. See your Installation Guide for more information on using the EZWebCon software. Note: The Server must be added as a Windows NT printer before it can accept print jobs from a Windows NT host. An Server servicing LAN Manager print queues must have the LAN Manager protocol enabled (the default). To verify that LAN Manager is enabled, enter the List Protocols command. 11.
Printing Methods LAN Manager Host Setup 2 In the Printer Name box, enter a printer name of up to 32 characters. 3 In the Driver box, select Other to install a printer driver, then select the desired printer driver from the pull-down menu. 4 Enter a description string in the Description box. 5 If applicable, choose the Share this printer on the network option. (This is not recommended until the print queue is confirmed to be running properly.) 6 In the Print To box, scroll to the Other option.
LAN Manager Host Setup Printing Methods 11 Click the OK button in the remaining print dialog boxes to return to the Print Manager dialog. 12 If you’d like this printer to be the default printer, click on the Default pop-up menu and scroll to the printer’s name. Figure 11-6: Print Manager Window EPS_PRT 13 The printer is now ready to accept jobs. 11.1.2 NetBIOS To install NetBIOS, first create a service with LAN Manager enabled.
Windows NT Troubleshooting LAN Manager Host Setup 4 The Windows NT node will attempt to connect to the Server; if it cannot do so, it will inform you of the problem. At this point, all references to LPTn (the port specified with the NET USE command above) will go to the service that you created. For testing purposes, you can try to use a copy command. 5 To make the lpt redirect permanent, enter the following command.
LAN Manager Host Setup Windows NT Troubleshooting On some versions of Windows NT, editing the timeout period does not actually change the 45 second timeout period. If you are unable to change your timeout period, try using LPR instead. ◆ Windows NT supports printing via AppleTalk and LAN Manager. However, the Server and NT AppleTalk implementations are not compatible at this time; the Server cannot accept AppleTalk jobs from Windows NT hosts.

A: Contact Information If you are experiencing an error that is not listed in Appendix B: or if you are unable to fix the error, contact your dealer or Lantronix Technical Support at 800-422-7044 (US) or 949-453-3990. Technical Support is also available via Internet email at support@lantronix.com. A.
B: Troubleshooting Before troubleshooting your Server, 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 Server has a unique IP address before proceeding.
DHCP Troubleshooting Troubleshooting B.2 DHCP Troubleshooting Table B-2: DHCP Troubleshooting Area to Check Explanation DHCP is enabled on the Server. Use the Set Server DHCP Enabled command. If you manually enter an IP address, DHCP is automatically disabled. Make sure the DHCP server is operational. Check to see that the DHCP server is on and is functioning correctly.
Troubleshooting RARP Troubleshooting B.4 RARP Troubleshooting Table B-4: RARP Troubleshooting Area to Check Explanation The Server name and hardware address in the host’s /etc/ethers file The Server name and hardware address must be in this file for the host to answer a RARP request. The Server name and IP address in the /etc/hosts file The Server name and IP address must be in this file for the host to answer a RARP request.
PostScript Problems Troubleshooting PostScript printers will silently abort jobs if they detect an error. Table B-6: PostScript Troubleshooting Area to Check Explanation The Server is communicating with the printer To test a PostScript printer, use the Test Port 1 PostScript Count 2 command. This command will send 2 pages of PostScript data out the parallel port. Watch the indicators on the printer to verify that the Server is communicating with the printer.
C: Updating Software Current software files (MPS.SYS) are available on the distribution CD. Software updates and release notes for the Server 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 MPS.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 C.2.1.1 TCP/IP Before the Server downloads the new software, it will send DHCP, BOOTP, and/or RARP queries (all are enabled by default). Next, the Server will attempt to download the MPS.SYS file using TFTP (Trivial File Transfer Protocol). Note: EZWebCon can also be used to reload software. See the Readme in the EZWebCon directory on the distribution CD-ROM.
Troubleshooting Flash ROM Updates Updating Software C.3 Troubleshooting Flash ROM Updates Many of the problems that occur when updating the Flash ROM can be solved by completing the following steps. Table C-1: Flash ROM Troubleshooting Protocol Area to Check NetWare Ensure the file is in the login directory. Since the Server cannot actually log into the file server, it has very limited access to the server directories. TFTP Check the file and directory permissions.
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.
DHCP Glossary DHCP Dynamic Host Control Protocol. DHCP allows nodes on the network to lease IP addresses from a DHCP server. If the node has been configured to query a DHCP server, the node will receive a temporary IP address each time it boots. When a node is no longer using the IP address, it goes back into the pool of available IP addresses for the next query. download The transfer of a file or information from one network node to another.
Glossary LAT many other nodes and networks a node can “see” on its network, addresses are either assigned to nodes (in the case of large, cross-country networks) or chosen randomly (for small networks that do not connect to the outside world). Each software address should be unique across all the networks it can access. See network address. LAT Local Area Transport. LAT is a Digital Equipment Corporation proprietary network communication protocol.
nameserver Glossary nameserver A device that translates (or resolves) text hostnames (such as alex.ctcorp.com) into their numeric IP address equivalents (such as 192.0.1.55). IP addresses can be routed easily since hosts on the network know how to map numeric addresses to exact hosts. Hosts have more trouble with names, and this is where name servers come in.
Glossary RARP RARP Routing Address Resolution Protocol. RARP allows a node to broadcast a message asking for an IP address given its hardware address. If a RARP server has been configured to reply to this node, it will tell the node what its IP address should be. Note that RARP provides less information than BOOTP, but is more widely implemented. repeater A network device that repeats signals from one cable onto one or more other cables, while restoring signal timing and waveforms.
rwho rwho Glossary A UNIX feature that enables network hosts to know what users and systems are on the network without actively connecting to them. If rwho is enabled on a host, it both sends and receives network broadcasts containing this information. The packets generally contain the host’s name, IP address, and the number and names of the users on the system.
Glossary tap 192.8.12.34 would be considered as part of a different network, however, since the network mask comes out to be 192.8.0.0 which does not match the previous two masks. In this second case, the gateway host would be used—if it had not been defined, the connect attempt would fail. If the subnet mask is not set explicitly with the Set/Define Server Subnet Mask command, the Server will assume a mask based on its IP address and thus the apparent network type. This mask will be 255.255.255.
Thinwire Glossary Thinwire Thin, co-axial cable similar to that used for television/video hookups and typically used with BNC-type connectors. Thinwire cable is much easier to route and work with than Thickwire, but it should not be run more than 185 meters (~600 feet) without using a repeater to reinforce the signal. Thinwire connectors are usually seen on terminal servers, personal workstations, networked printers, and in networks where the nodes are all relatively close to each other.
