Introduction 1 - Introduction The MSS1-T and MSS1-T2 are multiprotocol micro serial servers that provide Ethernet connections for personal computers, terminals, modems, and devices that would not otherwise be connected to a network. The MSS100 additionally provides Fast Ethernet support. NOTE: In this manual, all MSS models will be referred to as Òthe MSSÓ or Òthe ServerÓ unless a distinction needs to be made between the models.
Terms Introduction The PDF versions of the MSS manuals are located in the manuals directory of the CD. Use the Adobe Acrobat Reader (widely available on the Internet at no charge) to read and print all or parts of the manual from the PDF Þle. 1.1 Terms In this manual, the following terms are used to describe parts of a network. Host A computer attached to the network. The term host is generally used to denote interactive computers, or computers that people can log into.
Introduction Software The MSS also implements basic Simple Network Management Protocol (SNMP) functionality. SNMP commands enable users, usually system administrators, to get information from and control other nodes on a local area network (LAN), and respond to queries from other network hosts. The MSS allows conÞguration of one community name with read/write access. ¥ IPX/ SPX (NetWare) The MSS provides IPX/SPX access to the serial device from NetWare and any other IPX/SPX nodes.
Configuration Introduction When using IPX or LAT, it is possible to power up the MSS and have it work properly with no additional conÞguration required. TCP/IP users must give the unit an IP address. NOTE: For more information about methods used to configure an IP address, see IP Address Configuration in. Lantronix has provided EZWebCon software to help users install and conÞgure the MSS. It is also possible to conÞgure the MSS settings by logging into it over a network via Telnet or Rlogin.
Installation MSS Components 2 - Installation This chapter covers the installation of the MSS in an Ethernet network and the attachment of a serial device. Basic knowledge of networking installation is assumed. Read this section completely before continuing. 2.1 MSS Components The MSS front panel has a male DB25 serial connector. The following Þgure shows an MSS1 front panel. The MSS100 rear panels is more narrow.
Installation Installation Four or Þve LEDs are located on the top of the unit. Table 2-1 explains their functions.
Installation Installation As you follow the installation steps, refer to the numbers in Figure 2-3. 1. Select a location. The MSS should be positioned close to the device it will be servicing. Since powering down the unit will terminate any active sessions, it may be desirable to place the server in a location secure from user access. Also be aware of the unitÕs environmental operating limits and cabling requirements. See Appendix D for details. 2. Connect the MSS to a serial device.
Installation Installation NOTE: Be sure to use the MSS1 6V power supply for your MSS1 and the MSS100 5V power supply for your MSS100. Using a power supply with the wrong voltage will damage the MSS. Check to see if the Power and Link LEDs on the front of the server light. If not, unplug the server and check the power supply, then check the Ethernet connection and plug the server in again. If the LEDs still do not light, refer to Appendix B, Troubleshooting. 2.2.
Installation Is It Working? 2.3 Is It Working? If the MSS appears to be working and the unit is connected to the network, there are three ways to conÞrm that it is working correctly: ¥ If there is a terminal attached, press the Return key and log in. If you are able to log in, the server is running normally. ¥ If an IP address has been conÞgured for the MSS (see IP Address ConÞguration on page 3-2), ping the MSS from a TCP/IP host. Figure 2-4: Pinging the MSS unix% ping 192.0.1.
Getting Started 3 - Getting Started This chapter covers all of the steps needed to get the MSS on-line and working. There are three basic methods used to log into the MSS and begin conÞguration. 1. Incoming (Remote) Logins: EZWebCon is the preferred conÞguration method for TCP/IP and IPX users. For TCP/IP and LAT users, other remote login options are available (see Telnet on page 3-6). 2.
IP Address Configuration Getting Started 3.1 IP Address Configuration When using IPX or LAT, it is possible to power up the MSS and have it work properly with no additional conÞguration required. However, for TCP/IP use, an IP address must be conÞgured for the MSS before any TCP/IP functionality is available. There are three ways to conÞgure the IP address: 1. Using EZWebCon 2. Using an ARP entry and the ping command from a network host 3. Using a host DHCP, BOOTP, or RARP server 4.
Getting Started IP Address Configuration NOTE: The ARP/ping method only works during the first two minutes of MSS operation. After two minutes, an alternate method must be used or the MSS must be rebooted. On a UNIX host, create an entry in the hostÕs ARP table and substitute the intended IP address and the hardware address of the server, then ping the server (see Figure 3-1). This process typically requires superuser privileges. Figure 3-1: Entering ARP and Ping (UNIX) # arp -s 192.0.1.
IP Address Configuration Getting Started Figure 3-3: Changing the IP Address % telnet 192.0.1.228 Trying 192.0.1.228 Lantronix Version n.n/n (yymmdd) Type Help at the ‘Local_>’ prompt for assistance. Enter Username> gopher Local> SET PRIVILEGED Password> system (not echoed) Local>> CHANGE IPADDRESS 192.0.1.228 Any host wishing to access the MSS will have to be told the MSSÕs IP address. This is typically conÞgured in the unix Þle /etc/hosts or via a nameserver.
Getting Started Incoming Logins Figure 3-4: Entering the IP Address at the Local Prompt Local> SET PRIVILEGED Password> system (not echoed) Local>> CHANGE IPADDRESS 192.0.1.228 If the MSS has encountered a problem with the Ethernet network, it will send an alert message to the console and wait ten seconds to detect serial port activity before attempting to Þnish booting.
Serial Port Logins Getting Started 3.2.3 Other Incoming TCP/IP Logins 3.2.3.1 Telnet To log into the MSS, type ÒTelnetÓ followed by the MSS IP address. The MSS must have an IP address assigned. Figure 3-5: A Telnet Connection % telnet 192.0.1.88 3.2.3.2 Rlogin Rlogin allows users to connect to a remote device as if they were on the local network. Rlogin is enabled by default. Figure 3-6: An Rlogin Connection % rlogin 192.0.1.88 3.2.
Getting Started Remote Console Logins 3.4 Remote Console Logins The MSS enables a TCP/IP user to conÞgure the server via a single Telnet connection to the remote console port, designated as port 7000. Connections to the console port cannot be disabled. This ensures that administrators will always be able to log into the port. To connect to the remote console port, use the Telnet command followed by the MSSÕs IP address and the remote console port number.
Logout Getting Started 3.5.2 SPX The MSS and the target device must advertise themselves via SAP announcements. To view all available SPX devices (those advertising themselves) type Show Nodes SPX at the Local prompt. Then type ÒSPXÓ followed by the target deviceÕs SAP name. Figure 3-10: SPX Connection Local> SPX sap_name 3.5.3 LAT To connect to a LAT service, type the word ÒLATÓ followed by the name of the desired host or service.
Basic Configuration Command Set 4 - Basic Configuration Certain parameters must be conÞgured before the MSS can function in the network. EZWebCon is the recommended way to communicate with and conÞgure the MSS. This chapter shows an additional method of conÞguration: the command line interface and MSS command set. NOTE: Instructions for using EZWebCon are included on the distribution CD-ROM. EZWebCon also has on-line help to assist you with configuration. 4.
Protocol Configuration Basic Configuration If another user is currently the privileged user for the MSS, use the Set Privileged Override command to forcibly become the privileged user. To relinquish privileged status, enter the Set Noprivilege command. The privileged password can be changed with the Change Privpass command. Specify a new password of up to six alphanumeric characters. Figure 4-2: Changing Privileged Password Local>> CHANGE PRIVPASS “walrus” 4.2.
Basic Configuration Protocol Configuration A default domain name can also be conÞgured for the purpose of name resolution. When a user types a host name, the MSS will add the domain name and attempt the connection. Ex: ¥ Gateway: TCP/IP networks rely on gateways to transfer network trafÞc to hosts on other networks. The MSS will learn which hosts are gateways for the local network by listening to broadcasted IP routing packets, or it can be explicitly told which hosts are gateways.
Serial Port Configuration Basic Configuration 4.3.3 LAT Parameters ¥ Server IdentiÞcation String: The MSS can be given a descriptive identiÞcation string of up to 40 characters so that users on a LAT network can identify the MSS. Ex: ¥ Service Groups: The MSS serial port and the services on the network each belong to one or more service groups. Devices can only connect to services if they both belong to a common service group.
Basic Configuration ¥ Autobaud: The autobaud feature can be enabled or disabled (the default). When enabled, the MSS will automatically attempt to match its speed to that of the remote device upon connection. Ex: ¥ CHANGE STOPBITS 2 Parity: The MSS supports even and odd parity, as well as settings of Mark, Space, and None (the default). Ex: ¥ CHANGE CHARSIZE 7 Stop Bits: The MSS can use 1 stop bit (the default) or 2.
Serial Port Configuration ¥ DTRwait: DTRwait delays the MSS from asserting DTR until the port is actually in use, whether due to a login or a network connection. It is disabled by default. Ex: ¥ CHANGE INACTIVE LOGOUT ENABLED Inactivity Timer: When Inactivity Logout is enabled, the port will automatically log out after an idle period of 1 to 120 minutes, depending upon the speciÞed timer value. The default is 30 minutes.
Basic Configuration Serial Port Configuration A dedicated service is conÞgured the same way as a preferred service. No dedicated service is conÞgured for the MSS by default. Ex: CHANGE DEDICATED LAT:LN=vax8:LD=0005 NOTE: Because dedicated connections leave no easy way to log into the server, configuring the MSS serial port for dedicated service is not recommended unless incoming logins are enabled. Otherwise, only Telnet console port connections are possible.
Using the MSS Incoming Connections 5 - Using the MSS This chapter explains how to use the MSS interactively and with host applications. Host-initiated (incoming) connections include: ¥ Making socket connections to TCP/IP and IPX/SPX hosts. ¥ Making LAT connections to VMS, Ultrix, and OSF/1 hosts. ¥ Using host applications with the MSS. ¥ Using the code examples included with the MSS.
Incoming Connections Using the MSS 5.1.1.1 TCP/IP Socket Connections The MSS supports TCP/IP socket connections to ports 2001 and 3001. Opening a TCP session to port 3001 will form a raw TCP/IP connection to the serial port. Port 2001 can be used when Telnet IAC interpretation is needed. To specify a connection to a socket, use the Telnet command followed by the MSS IP address (or resolvable name) and the desired socket number. Figure 5-1: TCP/IP Socket Connection % TELNET mymss:2001 5.1.1.
Using the MSS Incoming Connections NOTE: The procedure is similar for DEC UNIX LAT. If heavy input or output loads are expected on the LTA port, you can set alternate type ahead to reduce ßow control on the ports. Figure 5-4: Reducing Flow Control $ SET TERM/PERM/ALTYPEAHD LTAnnnn To connect to the MSS serial port from a VMS host, use the command below and include the appropriate LAT application port number: Figure 5-5: Connecting to the MSS $ SET HOST/DTE ltannnn 5.1.
Interactive Connections Using the MSS 5.1.4 Code Examples The MSS distribution CD-ROM includes examples of code for TCP/IP and SPX/IPX applications. Refer to the Readme Þle included with the code examples for further information and instructions. 5.2 Interactive Connections Interactive mode refers to entering commands at the Local prompt. Commands can be used to conÞgure the MSS, connect to remote services, manipulate a connection, or receive feedback. 5.2.
Using the MSS Interactive Connections 5.2.1.3 Backward and Forward Switches The Backward and Forward commands, when entered in local mode, allow users to navigate through current sessions. The Change Backward Switch and Change Forward Switch commands deÞne keys that can be used to switch sessions without returning to local mode. The MSS intercepts and processes these switch keys; it does not pass them to the remote host. No backward or forward switch keys are enabled by default.
Interactive Connections Using the MSS 5.2.1.4 Disconnect and Resume Users need a method of controlling and disconnecting sessions from local mode. For example, if a session on a remote host freezes or hangs while executing code, the user can exit the session using the Break key, then terminate the connection by entering the Disconnect command at the Local prompt. A user may resume a session after returning to local mode by entering the Resume command.
Using the MSS Interactive Connections Sometimes the presence of Newline characters creates a problem during a Telnet session. When the MSS Telnet padding feature is enabled with the Change Telnetpad command (the default), the server will automatically pad carriage returns with null characters. This behavior works for most applications and is recommended in the Telnet RFC. 5.2.2.2 Rlogin Rlogin allows a user to log into a remote host as if he or she were a local user.
Interactive Connections Using the MSS 5.2.2.4 LAT LAT devices broadcast their services to the network along with ratings, which are estimates of how busy the services are. Ratings range from 0 to 255; a 255 rating means that the service can accept connections while a zero rating means that the service is in use and connection attempts will be denied. By default, connection attempts are made to the highest-rated service bearing a given name.
Using the MSS Interactive Connections 5.2.3 Status Displays These eleven commands display information about the current conÞguration and operating status of the MSS. The following sections describe what a user will see when typing the Show commands in interactive (local) mode. 5.2.3.1 Show Hostlist This command shows the current contents of the host table used for multihost mode connections. Host entries are numbered from 1 to 8. 5.2.3.
Interactive Connections Using the MSS 5.2.3.7 Show Server Characteristics This command displays network-related server identiÞcation information including the MSSÕs hardware address, node address, IP address, domain, any conÞgured gateways and nameservers, and the subnet mask. In addition, inactivity and retransmission limits, password restrictions, and the types of incoming logins permitted are shown. 5.2.3.
Using the MSS Emulating a Direct Serial Connection 5.3 Emulating a Direct Serial Connection Two MSS serial servers can be connected to emulate a direct serial connection on a LAN. Servers connected in this way can pass data only. They will not be able to pass status signals (DSR, DTS, CTS/RTS, etc.) or preserve timing between characters. The basic network conÞguration for this virtual serial line is shown in Figure 5-14.
Multihost Mode Using the MSS In UDP mode, each MSS would have to be conÞgured to both send packets to and accept packets from the other MSS. The conÞguration is as follows: mss_a Local>> CHANGE DEDICATED TCP 192.168.5.10:4096U Local>> CHANGE AUTOSTART ENABLED Local>> CHANGE ACCESS DYNAMIC mss_b Local>> CHANGE DEDICATED TCP 192.168.5.2:4096U Local>> CHANGE AUTOSTART ENABLED Local>> CHANGE ACCESS DYNAMIC Setting up Dedicated hosts ensures that the units will always talk to each other.
Using the MSS Multihost Mode 5.4.1 Configuring Multihost Mode To conÞgure the MSS for multihost mode, Þrst set the MSS for a dedicated multihost connection using the Change Dedicated Hostlist command. Figure 5-15: Setting the MSS for Multihost Mode Local>> CHANGE DEDICATED HOSTLIST NOTE: When a dedicated connection is enabled, local mode hotkeys for session manipulation are disabled. Next, conÞgure the list of hosts with which to communicate using the Host Add command.
Multihost Mode Using the MSS There are a few important things to note about multihost connections: ¥ The MSS will pingTCP and UDP hosts before sending packets to make sure the remote hosts are alive. If they are alive, the MSS makes the real connection and passes the data. If any of them arenÕt alive, the MSS doesnÕt connect or retry. ¥ If one of the host connections is terminated prematurely, the MSS will attempt to reconnect at preset intervals.

Troubleshooting Problems and Error Messages B - Troubleshooting This Appendix discusses how to diagnose and Þx errors quickly yourself without having to contact a dealer or Lantronix. It will help to connect a terminal to the serial port while diagnosing an error to view any summary messages that will be displayed. NOTE: When troubleshooting, always ensure that the physical connections (power cable, network cable, and serial cable) are secure.
Problems and Error Messages Troubleshooting Table B-1: Problems and Error Messages, cont. Problem/Message Error Remedy The MSS completes its There is a problem with the power-up and boot serial connection or the setprocedures, but up of the serial device. thereÕs no noticeable serial activity. Check the terminal setup and the physical connections, including the cable pinouts (see Appendix C). Try another serial device or cable, or cycle power on the MSS.
Troubleshooting BOOTP Troubleshooting B.2 BOOTP Troubleshooting BOOTP failure does not disable the unit from booting. If the BOOTP request fails even though you have conÞgured your host to respond to the request, check the following areas: Table B-2: BOOTP Troubleshooting Area to Check Explanation Is BOOTP in your /etc/services Þle? BOOTP must be in the /etc/services Þle as a real TCP/IP service. It must not be commented out.
TFTP Troubleshooting Troubleshooting B.3 TFTP Troubleshooting If the TFTP request fails even though you have conÞgured your host to respond to the request, check the areas discussed in the following table. Table B-3: TFTP Troubleshooting Area to Check Explanation Is TFTP enabled on Ensure that the /etc/inetd.conf Þle has an uncommented line the loadhost? enabling the TFTP daemon. Machines may have the TFTP daemon line commented out. If the /etc/inetd.
Troubleshooting Entering Commands at the Boot Prompt For example, a typical TCP/IP conÞguration might use the following commands: Figure B-1: BCP Command Examples Boot> CHANGE IPADDRESS 192.0.1.229 Boot> CHANGE SOFTWARE /tftpboot/MSS1.SYS Boot> CHANGE LOADHOST 192.0.1.188 Boot> CHANGE SECONDARY LOADHOST 192.0.1.22 Boot> FLASH % Initialization begins in 5 seconds..... These commands set the MSS IP address, the software loadÞle, and the loadhostÕs IP address (as well as that of a backup loadhost).
Entering Commands at the Boot Prompt Troubleshooting Ð Ipaddress ip_address specifies this serverÕs IP address. Uses the standard numeric format. Ð Loadhost ip_address specifies the host to attempt to load the file from. The IP address should be in standard numeric format (no text names are allowed). Ð Netwserver fileserver specifies the NetWare fileserver from which the MSS will attempt to load the loadfile.
Troubleshooting Modem Configuration Checklist B.5 Modem Configuration Checklist Most modem problems are caused by cabling mistakes or incorrect modem conÞguration. However, the following items should be veriÞed after any modem conÞguration, and re-checked when there is modem trouble. ¥ The modem must disconnect immediately when DTR is de-asserted. ¥ The modem must assert CD (or DSR, if connected) when connected to another modem. It must not assert CD when disconnected.
Pinouts DB25 Connector C - Pinouts In the following diagrams, unlabeled pins are not connected. C.1 DB25 Connector The Þgure below shows the pin connections of the MSS DB25 connector. Figure C-1: Pinout of DB25 Serial Port RX (in) TX (out) Ground CTS (in) RTS (out) DSR (in) CD (in) DTR (out) C.2 RJ-45 Connector Lantronix servers are RS-423 compliant, and are thus limited by the equipment at the remote end of the serial line.
Modem Wiring Pinouts C.3 Modem Wiring C.3.1 DSR (Data Signal Ready) versus CD (Carrier Detect) By default, most modems assert CD only during a valid connection. In this case the modemÕs CD pin may be wired to the ServerÕs DSR pin. Alternately, many modems can be conÞgured such that DSR acts like CD. In this case, the modemÕs DSR pin may be wired to the ServerÕs DSR pin. C.3.2 DTR (Data Terminal Ready) The MSS normally asserts DTR.

Reloading MSS Software ¥ Updating Software Use the Show Server Bootparams command to check the MSS settings and verify that the correct download Þle has been conÞgured before using the Initialize Reload command to reboot the server and reload the code. NOTE: It is very important to check the MSS settings before using the Initialize Reload command; this ensures you are reloading the correct software file. The reloading sequence is as follows: 1.
Updating Software Reloading MSS Software D.2.2 TCP/IP Downloading involves the Trivial File Transfer Protocol (TFTP), and optionally BOOTP. The MSS will make a BOOTP query each time it boots. If a host provides BOOTP support, it can be used to set the ServerÕs IP address and loadhost information. Add the ServerÕs name, IP address, hardware address, download path, and loadÞle name to the BOOTP Þle (usually /usr/ etc/bootptab).
Troubleshooting Flash ROM Updates Updating Software D.3 Troubleshooting Flash ROM Updates Many of the problems that occur when updating Flash ROM can be solved by checking the following: NetWare The loadÞle must be in the login directory; the MSS cannot actually log into the Þleserver. TFTP The Þle and directory must be world-readable. The loadhost name and address must be speciÞed correctly, and their cases must match those of the Þles on the host system.
