Re: port 6051: hacked?

A followup from myself:

First,
thanks for all the answers. 
To summarise:

neither lsof, nor netstat or fuser gave a sign that any program on my
server listens on that port. I have aide running on this machine so i
am quite sure that the the programs are intact. 

>From what Kristof Goossens and Nikolay Hristov say, i guess there is a
firewall at the provider, that is blocking the port, which seems to be
used by arcserve.

As for "Why so many open ports?", well, i turned the firewall off for
scanning :-)

I am now quite shure that there was no breakin, but will follow the
suggestion by Jean-Francois Dive an let a sniffer run...

Thanks again,
Ramin
