Is Linux installed on the same PC as the cablem modem was connected too?  
Some (all?  Is this a DOCSIS thing?) Cable inet provides use the MAC of 
the ethernet card,  if you switch ethernet cards it may stop working.

Masq.  But without any fancy stuff you should be able to ping from the 
box directly connected to the cable modem.  Does the interface come up?  
Is the IP the same as if you were connected under windows/from the 
windows box.  Run winipcfg in win9x and see what the interface looks like 
when it's functioning.  If your ISP uses DHCP you can run "/sbin/pump -i 
eth0 --status" as root to see if anything coughed up. (assuming the cable 
modem is attached to eth0).  Some provides use weird things like PPPoe 
(will work under Linux with a little wrestling) or even "PPTP over ATM 
cell" (I have no idea how the hell that works), just because a more 
complicated solution must be better.

Not me (DSL!), but yes.

Careful, some people on this list are very touchy about digressions.  The 
fact that I'm not launching into a political diatribe is quite 
impressive, and I DEMAND kudos for my restraint!
