[tcpdump-workers] tcpdump problem

[Mercia Eliane Bittencourt Figueredo]

Hello,

I am trying to generate some traces. I am working with linux-2.4.9-ac5 ,
 tcpdump-2001.09.21 and  libpcap-2001.09.21 .
I have tried to use some expressions for filter packets, but it does not work...
I did some tests:


[root@gandalf tcpdump-2001.09.21]# tcpdump -i atm0|more
