Canals: Help manage SSH tunnels

Canals eases the process of creating and managing SSH tunnels. Behind the scenes, Canals creates SSH tunnels using the standard OpenSSH library, but it helps with making the process more forward and by remembering those tunnels between usages.

SSH tunnels tend to die after some time. it's sad but true. but we can do something to try and keep them alive as long as possible. Edit your ~/.ssh/config file (and if it doesn't exist, create it) and add the following 2 lines:

Host *
  ServerAliveInterval 60

so in the end:

$ cat ~/.ssh/config
Host *
  ServerAliveInterval 60

$ chmod 600 ~/.ssh/config
$ chown uesr:group ~/.ssh/config

(where user:group is your user:group on your system)
