Is there any program or service that can monitor a port on a dedicated server? (game server) that can notify me on my cell phone via text message, aim message, or voice message when a server goes down (port monitoring) or something?
My phone provider gives me an e-mail address where all e-mails
are forwarded to my cell. I use nagios which e-mails me everytime
a service is down.
If your provider doesn't offers this I'm sure there are services that will
do this for you. a google "email to sms" will give you a place to start.
