Chapter 7. Troubleshooting 237
• Windows 95 may remember MAC addresses: if you have changed MAC addresses, reboot the router and
the PC.
• In Windows 3.1., check that the TCP driver is installed correctly. Ping (
ping
command) your PC’s IP
address from the PC.
• Successful “pinging” results let you know that the TCP driver is working properly.
• If you have changed an IP address to map to a different MAC device, and
ping
or IP fails, reboot your
PC.
•Use the
iproutes
command to verify which router’s name is the default gateway (this cannot be 0.0.0.0).
IPX Routing
• Check that IPX routing has been enabled and that the remote end is enabled for IPX routing.
• Validate that the IPX WAN network number matches the remote router’s WAN network number.
• Check that IPX SAPs correctly identify the servers and applications on the remote network and have
valid network numbers, node numbers, etc.
• Check that every SAP has a router to its internal network.
• Check that the IPX routes (network numbers, hops, and ticks) seeded into the routing table for network
segments and servers beyond the remote router are correct.
• Validate that the IPX WAN network number matches the remote router’s WAN network number.
• Check that the IPX routes (network numbers, hops, and ticks) seeded into the routing table for network
segments and servers beyond the remote router are correct.
• Check that IPX SAPs correctly identify the servers and applications on the remote network and have
valid network numbers, node numbers, etc.
• Be sure to reboot if IPX addresses, routes, SAPs or control has been changed.
• If the router fails to negotiate IPX:
• Make sure that at least one WAN number is not equal to zero at one end of the link.
• The server must have an IPX route to the remote LAN.
• The Novell server needs to have
burst mode
turned on.
• Large Internet packets have to be turned on:
• Novell 3.12 and later:
• Client needs VLM.EXE, net.cfg: large Internet packets=ON, Pburst=5
• If you can’t see the server SAPs:
• Check the frame types using the
eth list
command and ensure that they are the same on both routers.
• Check that the Ethernet cable is correctly plugged in.
• Make sure that the Novell server is up.
