tunnelkeeper

TunnelKeeper keeps SSH tunnels open

Install it as a service with tunnelkeeper install.

Edit the config file /opt/tunnelkeeper/etc/tunnelkeeper.conf. If you make changes to tunnelkeeper.conf, run systemctl restart tunnelkeeper.

There are 3 sections:

settings

• debug [0..3]: Debug logging levels 0 (no logging) to 3 (too much logging).
• timeout: Echo check timeout for watched connections.

ssh

• It's an ssh config file, so see man ssh_config for information. TunnelKeeper will connect to each host listed, and make sure every connection in tunnelkeeper.conf stays open in the background.
• There are 2 options that aren't available in normal ssh config files:
  • Watch : Enables an echo test on the host at regular intervals.
  • Password : Uses screen to log in with a password. This is insecure, since the password is in plaintext, so use passwordless auth if possible.
