MC,
can you please try:
netstat -a | grep 3299
alternatively you can use is a tool called lsof, which you can download.

MC,
sorry for second post!
Have found the latest version of lsof at:

Hi

Just use the command

# lsof | grep 3299

It will show you the program/command that is using the TCP Port 3299 .

Hi Miguel,

If you have lsof simply run the below-listed command, which will show the process that is listening on that port as well the current network sockets:

# lsof -iTCP:3299

cheers!

If you don't have lsof installed on the system, you can do:

netstat -n |grep 3299

this won't show you the process, but if it returns anything, will show you if it's being used. If it returns nothing, that means the port is not in use only at that time. If you have applications on the system that use tcp sockets, you may want to check with the application vendors or any of your coworkers who work with the apps about where the configurations files are to see if that port has been set-up for use.

Miguel -
While I use netstat as other have mentioned, my weapon of choice is ndd for the additional information the output contains.

i.e.
ndd -get /dev/tcp tcp_status | grep ce3

ce3 being the hex value for 3299

The output will identify what the port is connected to as in remote ip and remote port.
