Network connections monitor


I was googling for a connection monitor but I couldn’t find anything related to what I need.

My question is simple - is there any linux app or applet which is able to show (monitor) incoming and outgoing connections assuming it’s a direct internet access?

I was using a firewall on a system off Redmont which was able to show every connection, listening ports of services if some were opened etc.

Thanks in advance

You are not interested in traffic, but connections, right?

Anyway, you sound as if you asking for something like netstat. It will probably dump a lot more information than you want on to the screen, but a read of the man page will probably give you tools to control it.

For something like the connections on which the system is listening, try ‘netstat -l’ or ‘netstat -a’ for all.
