Troubleshooting Telnet Configuration

If you have trouble configuring the LAN/GPIB Gateway using Telnet with the default IP address of 192.0.0.192:

1Verify that the route command was performed properly. Use netstat -rto display the network routing tables.

2Verify that the Gateway is on the same local subnet as the client system from which you are Telneting. If not, consult your Network Administrator to determine if the default IP address will work from a separate subnet or to find a client system on the same local subnet that you can use.

3After the Gateway is powered on, press the Config Preset button on the back panel of the LAN/GPIB Gateway and verify the LAN Conn LED is flashing slowly.

4If the Telnet to the default 192.0.0.192 IP address does not work, try pressing the Config Preset button again. Depending on how your network is configured, the button may need to be pressed twice before the default IP address will be properly recognized and routed on the network. Or, one of the network values may be improperly configured on the Gateway, blocking a successful connection.

Troubleshooting BOOTP Configuration

If you are have trouble configuring the LAN/GPIB Gateway using the BOOTP configuration method:

1Verify that the Gateway’s configuration values are correct in the /etc/bootptab file for your BOOTP server.

2Verify that the BOOTP server system is configured to run the bootpd daemon. See the Administering ARPA Services manual for more information.

3Look for bootpd daemon errors in the syslog file on the syslog server for the BOOTP server.
