autossh - Automatically restart SSH sessions and tunnels

Update: Version 1.4f incorporates a number of changes and fixes to signal handling and exit conditions. The most notable changes are that it will exit properly when killed while waiting between ssh restarts, and it will now restart rather than exiting when the child ssh process is killed.

Previous update: Version 1.4e always sets the first poll time equal to the poll time, unless the first poll time is explicitly set with AUTOSSH_FIRST_POLL.

Previous update: version 1.4d fixes file descriptor issues when started without standard input available (for example, in system initialization scripts).

Previous update: version 1.4c disables the "gatetime" behaviour when -f is used, updates the list of OpenSSH options it knows about, and adds some fixes to configure.

Previous update: version 1.4b fixed a bug in polling, added a max lifetime option and a compile-time option to touch the pid file on each connection test.

BUILD

If you use OpenBSD or FreeBSD, autossh is available in the ports tree, and as a package that can be FTP'd down. Cygwin and some Linux distros also have it available as a package.
