TCP IP Ports

okay, here is an easy one.  I don’t want to let up on posting, so if I don’t have anything i’m currently working on (that seems interesting), I will post some stuff from my troubleshooting folder. 😛

This is just a common mapping of popular tcp ports.  this can help if you are wanting to open a firewall or just ran a netstat and saw you had connections you didn’t know about.  I will use this basically as a reference:
