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?
Do you need to access it from outside the campus network? Or just internally (from within the campus network)? – Isaac Dontje Lindell – 2013-01-20T21:53:28.243
I need it internally, but I figured that since I'll be on a different subnet it will pose similar issues as accessing it from off-campus. – Alex Bardasu – 2013-01-20T21:55:28.760
There is likely a firewall blocking inbound connections from the outside Internet. Internally, you might see if your campus network gives a DNS name for connected clients. My campus maps computers that request an IP into a DNS name with the format
%machine_name%.dynamic.%college_name%.edu
. Perhaps your network has something like that? – Isaac Dontje Lindell – 2013-01-20T21:58:31.423I get a similar address when I do a "host <ip>". I'll give it a try when I get off work and see if that gets me anywhere. Thanks! – Alex Bardasu – 2013-01-20T22:01:31.730
The one issue that I occasionally run into is that it doesn't update immediately when the computer moves around. That shouldn't be an issue on a machine that stays in the same place. – Isaac Dontje Lindell – 2013-01-20T22:14:21.040
