prog for scanning used ports

Hello,

I'm searching for a tool that can scan my local ports for traffic.
Something like tcpdump. It has to run on console.
After a run, the tool should reports me, all used ports for tcp,udp
connections during this run on my local computer.



thanks
Peter

I think maybe mrtg

You might like 'netwatch' (http://www.slctech.org/~mackay/netwatch.html)
or 'iptraf' (http://iptraf.seul.org/). Or maybe 'netstat -tuc' is all
you need?

For local interfaces, netstat -a will list all listening ports, all
socket connections, and status of those connections. An AWK or perl
script should put that data into a readable and trackable form.

You could also consider netstat -a -c 60 >> /tmp/netstat.log

which would write the output from netstat once a minute into
/tmp/netstat.log

You could analyse it from there, adjust the timings, etc.

Hello,

thanks to all of you for your posts.
I'm going to test your suggestions.

We set up a game server. There is no documentation for the configuration of
the firewall.
We only found some ip-ranges, but I do not think that all of this ports are
necessary.
We will see.

Peter
