Checking the Local Routing Tables

Use the netstat command to display the local routing tables:

# netstat -r

The following is sample output:

Make sure there is a routing table entry for each possible destination network. In particular, PPP devices, listed under Interface, should be matched with the appropriate host names listed under Gateway. The Gateway entry should, in turn, be matched with the correct entry under Destination.

Otherwise, if you are using static routing, add the appropriate static routes. If you are using dynamic routing with in.routed:

1. Verify that in.routed is running by typing:

   # ps -e | grep route

   If the routing tables still don't look correct, become superuser and continue with the next steps.

2. Kill in.routed by typing the process ID you got from ps -e as the argument to kill. For example, if 1384 was the process ID, you would type:

   # kill 1384

3. Flush the routing tables as follows:

   # /usr/sbin/route -f

4. Restart in.routed:

   # /usr/sbin/in.routed
