SPCHK (Server Port Checker)

This script is quite similar of SUP, however this one is so much more flexible. It's not just to keep a service running, it was made to check if a port in the server is listening. If its port is down, the Server Port Checker will execute a command setted by you, such as, your PHP script, service or even another script which may send an email to the server administrator.
