Hi,

I would like to know how can I list all the ports (TCP especially) configured on a machine ? In which files they are defined ?

TIA

Simply open a CMD window and type:

NETSTAT -A

This will show all your listening and connected ports.

I love TCP Mon from www.sysinternals.com  It shows you all ports open, as well as whethere they are listening, established, or time-wait.  It's real time so you can have it open and watch as TCP and UDP ports open and close.  They've got lots of other goodies at this site, some of the best tools I've found.

Active Ports will show you all ports TCP and UDP that are open on the system, and what process has them open, as well as displaying the local and remote IPs for each connection. I use this when I think a box has been compromised to see what's listening on the network.
