[LUNI] Networking question -please help

[Richard Reina]

Constantin,
 
 Thank you very much for your reply I tried the following:
 
 #:/sbin/service network stop
 unplug the cable from the router and into the LAN switch
 #:/usr/sbin/setup and manually set it to a valid LAN IP
 #:/sbin/service network start
 #:/sbin/service iptables restart
 
 but still can't ping any local machines.  I'm using Centos.  Thanks so much for the help thus far.  Any other suggestions on how I can accomplish this would be much appreciated.

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:

Stopping the network service should clear your arp table.
You might want to restart the firewall so it will pick up the new 
settings. For example, in Mandrake, restarting the network does not 
restart the firewall (shorewall).
