I recently setup a Linux machine in my dorm and I would like to be able to access it via SSH. I'm on a college campus that has several subnets to manage the machines connected wirelessly to the network. Because of this, the subnet of the machines and their IP changes frequently.
Since the machines will likely be on different subnets, I can't SSH by entering the IP address. Is there any way to set up SSH via an internet service or something similar that would forward me to my machine?
