Snort Error

[Messay <ramesis1 () yahoo com>]

I am somewhat a novice with Snort on Linux. I have installed  snort-2.0.2.tar.gz and libpcap-0.7.2.tar.gz on Linux 8.2. 
I'm running a laptop with 3com pcmcia card. 
(model: 3CCFE575CT). I have win xp on the same machine and have no problems with snort (win version)
I have followed all proper directions for installing snort on Linux and have received no errors during the process. 
However when I try to run snort i get the following error
============
Error: Failed to lookup for interface: no suitable device found. Please specify one with -i 
switch. Fatal Error, Quitting...
============
If anybody has any information or suggesting regarding the error I would appreciate some feedback. Thanks
