OpenSSH Heartbeat/Watchdog Patch 4.4p1 (Default)

Section: Unix

Added: Thu, Jun 19th 2003 20:23 UTC (5 years, 5 months ago)

Updated: Sun, Oct 1st 2006 04:24 UTC (2 years, 1 month ago)

About:
OpenSSH Heartbeat/Watchdog Patch adds a heartbeat (keepalive) function to ssh(1). If the output channel has been silent for more than a specified time, a null message (SSH_MSG_IGNORE) is sent to the server as a heartbeat. The heartbeat is useful for keeping connections over IP masquerade/NAT boxes, firewalls, etc. This patch also adds a watchdog timeout function to sshd(8). The combination of the heartbeat and the watchdog timeout is very useful for detecting a link which is down over unreliable connections such as a wireless network.

Release focus: Minor feature enhancements

Changes:
This version was adapted to OpenSSH 4.4p1. The documentation patch has been incorporated.

[»] usefulness ?
by mmu_man - Mar 11th 2005 23:24:19

I don't have problems anymore with my NAT router after I added "-o ServerAliveInterval=60" to the ssh command line setting up the tunnel here (using 3.9p1). Is that thing really needed ?

This patch might be useless if you are lucky enough to have no SSH1 server around you. More importantly, this patch (especially the latter half part) was originally developed to be used with the Authenticating Gateway.
