If you are using XP you might want to try the netstat program in a command
(dos) window. It's usually included in a routine XP installation.

netstat -n will give you a listing of active ports.

use netstat /? to give you the list of other options available for the
command.

Type netstat -a 10 at the command prompt.


Port scanning is a somewhat different matter.

Same for at least W98 up. Also see ipconfig.

you mention cports.exe by Nir Sofer. It's good .
there are these convenient programs. a well known one by sysinternals.
But,
I'm waiting for a program that'll tell me source/dest ip. i.e.
client/server ip.

not local/remote.

Local/remote won't tell me if it's incoming or outgoing. I don't mind
if it says local/remote along with incoming/outgoing. But they don't.

The date/time that connections are initiated would be useful.

I'd be interested in any ideas.

2 programs i've noticed come close..

ethereal - but you have to add an expression to it - to only show
connections initiated, and it is overkill really. it's a packet
sniffer. It's more GUI than necessary, it doesnt' make a convenient
port logger.

maybe
win NT port logger called "MS Port Reporter"- the issue I barely recall
with that is it only let you view the log as a file when you stop it,
it may not give process names, it prob gave time - which is good, i'm
not sure if it said incoming or outgoing. source/dest. At least it
gives the time , which is a feature missing frmo these GUI netstat like
snapshot like programs.
