Troubleshooting the Term Server

1 Reseting the Term Server

Resetting Term Server to Factory Defaults

  1. Remove power connector from the term server.

  2. Press and hold the small square button, labeled 'reset' next to power jack.

  3. Connect power to termserver, while continuing to hold in reset button.

  4. Continue to hold reset button until the POWER LED blinks on and off in a 1:5:1 sequence. If you interrupted the continuous hold momentarily, by slip/mistake, the 1:5:1 will not appear. If this is the case repeat till LED blink sequence is as noted. Once this LED is on continuosly, it has received its IP from host. NOTE: now use the browser interface described above to set port mode to RealPort.

The need for this activity is required each time to initiate the rarp requests. Our default configuration will be RealPort

When all is configured and operating correctly, the power and Ethernet UP LED should be continuously on, and the Ethernet activity LED will periodically flicker.

2 Troubleshooting communication to the Term Server

The following assumes that the host ethernet port and all cabling is working.

Required services on top of working ethernet:

/etc/rc.d/init.d/dgrp_daemon

/etc/rc.d/init.d/rarpd

If all is OK, check the port status with the following command:

'/etc/rc.d/init.d/dgrp_daemon status' the following output should be seen:


          #---------------------------------------
# Avail
# ID Major State Ports
#---------------------------------------
1 253 READY 4
        

If the digi daemon is running, but the ethernet link is not up 'Avail Ports' will show '0'. Also perform a grep on /var/log/messages for dgrp: 'grep -i dgrp /var/log/messages'. Status messages will show up here.

  1. Verify contents of /etc/ethers. Context: 'xx:xx:xx:xx:xx:xx 1.1.1.1' where xx's=mac address of term server, and 1's equal the IP in the hosts /etc/hosts file. Here is an example of t19's ethers file: 00:40:9D:22:C6:77 10.0.19.7

  2. Make sure rarpd is up and running. Do with '/etc/rc.d/init.d/rarpd status'. The follow is an example of output.

    root@t19]# /etc/rc.d/init.d/rarpd status

    rarpd (pid 1275) is running...

    [root@t19]#

  3. Do a 'tail -f /var/log/messages', looking for rarpd to log any requests it sees. Actually this is how I read the mac address of the device I am connecting. mac addresses unknown are logged here.

  4. do a 'tail -f /var/log/messages', looking for rarpd to log any requests it sees. Actually this is how I read the mac address of the device I am connecting. mac addresses unknown are logged here.

    username: root

    passwd: dbps

  5. Select Config, then Port and configure all ports to 'RealPort' mode, verses 'Terminal' mode. Select Admin and select reboot.

  6. When term server is back up, restart digi daemon, using '/etc/rc.d/init.d/dgrp_daemon restart'. Watch in /var/log/messages above for its messages.

  7. TPS reset should now work, allowing scans.
