Re: What are these ports for?



Hi Joern,
thats embarrassing - the server is built, installed and maintained by me
(and I didnt even know what ports are open there).

I used:
fstat | grep internet
and:
sockstat -l
- as Jeremy told me and cannot find any of these ports open though.

Filtered means they are not accessible at all?? Maybe thats just some
thing from #nmap -sS domainname.com ? Kind of confusing though.

Or is it 'filtered' by default via ipfilter what I use? But I surely
didnt put it into /etc/ipf.conf - very mysterious.

Thanks,
herb langhans
