Determining what ports Tomcat is running on

I've recently had problems connecting to a Tomcat server setup by another developer. In order to troubleshoot these problems, I wanted to use netstat to see what ports were being bound to, but apparently server sockets don't come up by default. If you really want to see what server sockets are in use on your machine, use the following :

netstat -lntp

The undocumented 't' option will cause netstat to show server sockets.
