Figure 5-1 Troubleshooting Networks that Use Repeaters
The same concept holds for communication through a gateway. If you suspect a gateway
problem, try the following procedures:
• To determine if you are set up to communicate with the desired node, execute the
following:
netstat -r
• To obtain routing statistics, execute the following:
netstat -rs
The statistics could indicate a bad route, suggesting a problem with a gateway node.
To identify such errors, do the following:
• Check with the node manager of the gateway node to ascertain proper operation
of the gateway.
• You can detect problems with the X.25 line by the number of errors shown when
you execute the following:
x25stat -f -d /devicefile
For more information on troubleshooting gateways, see the appropriate link manual.
For information on repeaters, see the HP-PB LAN Interface Controller (LANIC) Installation
Manual.
Troubleshooting Tips
This section provides useful tips for troubleshooting the Internet Services software.
When troubleshooting problems with the Internet Services, you need a reference point
to work from. For example, does the problem exist on the remote system or on the local
system? However, the terms local and remote are limited in their description of complex
communications, such as when a local system logs on to a remote system and then the
remote system logs back on to the local system. At that point, which is the local system
and which is the remote system?
