I did a telnet from my windowsmachine. My linux works as a
firewall/gateway/mailserver/etc. So yes from the same IP.

I managed to set up Suse, I managed to setup exim, I managed to setup a
firewall/gateway. But that took me ages. I'm not at all familiar with linux so
please explain how I would even setup a TCP dump.
I have ethereal to see wants going on on my ethernetcards but that's it.
I've read in the archives something about a verbose mode. What does that do?
