Wireshark · Ethereal-users: [Ethereal-users] TCP Filter problem

[Ron Apuzzo <admin@xxxxxxx>]

I downloaded the latest ethereal version 0.10.11 today. I can see all TCP 
and other traffic fine. Then I tried to put in a very simple filter "tcp 
port 23" and tried to telnet from host A(ethereal host) to host B. The 
result is only traffic from host A->B(23) was captured but not from 
B(23)->A. Promiscuous mode was turned off.

When I tried other TCP ports, same result! it never captured incoming 
traffic to the host running ethereal. Again with no filter I would see 
traffic from both directions which makes me believe that this is the 
problem of ethereal filtering. This is 100% reproducable.

Any hints or suggestions that I could try? I just want to capture traffic 
from A:xxxx <-> B:fixed_port but I want to capture both ways.

Thanks in advance for any inputs,
-Ron
