Hi Steve,
   sorry for jumping on the thread. I am on kernel 2.6.27 and there is
a big possibility  I haven't really understood your command.

You gave

tcpdump -s0 -w <output>.cap host <youripaddress>

I used :-

tcpdump -s0 -w output.cap host 59.95.28.28

(ouput.cap most probably is a file-name and the IP Address is the IP
Address being assigned by my provider)

but both for this I get

tcpdump: no suitable device found

Doing a cursory look at dmesg came across this .

[37479.042325] tcpdump uses obsolete (PF_INET,SOCK_PACKET)

My ifconfig.

$ ifconfig

As can be seen the active connection here is eth1.

The connection is between ethernet card and router.
