OpenSSH Heartbeat/Watchdog Patch enhances ssh(1) by adding keepalive functionality to ensure constant connectivity.
In addition to the heartbeat function, the OpenSSH Heartbeat/Watchdog Patch also includes a watchdog timeout function for sshd(8). The watchdog timeout function works in tandem with the heartbeat function to quickly detect any down links that could be an issue, particularly over unreliable connections such as wireless networks.
The latest version of the OpenSSH Heartbeat/Watchdog Patch has been adapted to work with OpenSSH 4.4p1, and the relevant documentation patches have been incorporated. Overall, the patch's features make it a valuable tool for anyone who frequently relies on ssh(1) connections, particularly those who work with potentially unstable networks.
