Living behind a firewall can be a lonely and disparaging place to be. Using ssh's port forwarding capabilities has become an essential task to get through the day. Every few months something is closed off, and I add one more item to my morning startup routine. Opening ports to IRC, streaming music, and most recently mail are the first order of business at my business.
I have a machine in my home's DMZ, and my router will let all ssh traffic go to that machine. There is not a lot on that machine, it just provides extra help to my home machines, and lets my play with Ubuntu Linux.
To connect to IRC, I set host as
locahost instead of
host in Gaim. Every morning I issue the command:
ssh -C -N -f -L 6667:irc.gnome.org:6667 firstname.lastname@example.org
I just login to my IRC account, and ssh sends all my irc traffic over ssh to my computer that can talk over port 6667.
I can connect to irc.freenode.net at the same time. I use
6668:irc.freenode.net:6667 and get the port to
6668 and host to
locahost in Gaim.
To listen to Indy Pop Rocks
on SomaFM, I set its address as
http://localhost:8076 in Totem. I
ssh -C -N -f -L 8076:server1.somafm.com:8076 email@example.com
to do the routing. I could also be streaming from one of my home
computers using icecast. I would use something like
8080:transmitter.local:8080 to see it.
