Use lsof. If you don't have it, get it here:

Moreever you can use nmap as well for checking out the ports opened on your server. Try Google for nmap.

Well,basically you can use :

"netstat -an | grep "LISTEN" shows ports that LISTEN to incoming connection

"netstat -an | grep "EST" will show established (active) connections

This doesn't mean it doesn't work. It means you didn't find it. You could use the absolute path: /usr/local/bin/lsof

It does not matter what directory you are in. Typing lsof requires that the full path for this command is one of the paths shown in $PATH. If not, the command will not be found. If lsof is actually installed on your system, start with the common locations:

find /usr/local /usr/contrib /opt -name lsof

Then you type the fullpath to the command:

/usr/local/bin/lsof

Or you change the file: /etc/PATH to add /usr/local/bin (or whatever is needed) so that the fullpath can be found.
