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

[Carlos Carrero Gutierrez]

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).
