If anyone faces a freeze with Ubuntu where you cannot do anything, then this will certainly be helpful if you want to reboot the OS as cleanly as possible without damaging their HDD's or losing their data.
If you do a lot of tweaking to the panels in Gnome or KDE, you've probably run into an instance where you enabled a plugin or changed a setting and need to restart to see the effect (or maybe you locked something up). Instead of logging out or rebooting, we'll just reload the process.
Autossh is a program to start an instance of ssh and monitor it, restarting it as necessary should it die or stop passing traffic. The idea is from rstunnel (Reliable SSH Tunnel), but implemented in C. Connection monitoring is done using a loop of port forwardings. It backs off on the rate of connection attempts when experiencing rapid failures such as connection refused.
