Linux (RHEL) and ports...

Hi,

One of our applications running on RHEL is not working as expected - the application supplier has advised that a port is not allowing the correct traffic.

I know the port is open for incoming connections (checked with nmap and telnet) however is there a way I check the port is open for outgoing connections?

Iptables is disabled, so is SELinux.

Thanks
