Hi ng,

i've two linux systems (A and B).
I can successfully ping  A from B and vice versa.

A simple TCP-Connection from A to B is failing.
I'm using the following TCP SimpleServer and SimpleClient Examples:
http://homepage.uibk.ac.at/~c703350/csockets/simpleclient.c
http://homepage.uibk.ac.at/~c703350/csockets/simpleserver.c

The TCP/IP stack should be ok, since a TCP connection with this program
is working from A<=>A and B<=>B and from A<=>C

Does anyone has a hint what could be the problem?


Firewall on B perhaps? Or on A for that matter.
