I need to see open connections this moment - With Iptables i can only see logs

What about "netstat -nputa | grep ESTABLISHED"?. If I have understood correctly, that is what you need.

Hi, i use Iptables and i would like to find a tool or software in order

to see my open connections. In doesn't care if it's a gui or not, and it

can be not interactive (of course).

Wireshark capture paquets but i can't be constantly searching if a

paquet is correct or not.

Somebody could help me?

Thank you very much, and sorry (i am doing crossposting).

I think that you forgot to cross post to the Suse and Gentoo lists.

There is netstat -tulpen will show you open connections and by which program
(the program feature will only work if you run as root), but is not continuous,
i.e if you want an update you will need to run it again.
