[LUNI] Networking question -please help

[Mark Stuart Burge]

This might be a little late, but how many pcmcia slots do you have in 
the laptop ?
You could just run two interfaces, one set up for the lan and one set up 
for the wan.
Just switch the cable over when you want to change.

When I execute /sbin/ifconfig after trying to put the machine on the LAN ( via the method described below ) everything looks exactly the same as the other LAN machines but no pinging is possible.  I'm don't know how to clear the ARP tables.  Can someone suggest some additional steps that would help me switch this laptop over from the internet to the LAN without rebooting?  So far I execute:
