Package: autossh
Version: 1.4a-3
/usr/share/doc/autossh/README.Debian says:
[...]
Note: if your ssh client/server version is recent enough you can
obtain similar behaviour by setting ClientAliveCountMax and
ServerAliveInterval in /etc/ssh/sshd_config. See sshd_config(5).
This echoes a recommendation made by autossh's author, and it is
supposedly a superior method of accomplishing connection monitoring.
Given this, and that you know the range of SSH versions that will be
installed along side this Debian package (which should all be new enough
to support this...unless you're trying to support non-openssh clients
like dropbear), I recommend eliminating the random port selection logic
in the wrapper script, and instead have the wrapper script (pre)append
SSH options to implement the above.
Something like:
if [...existing code to skip this if -M or AUTOSSH_PORT is set...]
export AUTOSSH_PORT=0
monitor=("-o" "ServerAliveInterval ${AUTOSSH_POLL:=300}")
fi
exec /usr/lib/autossh/autossh "${monit...@]}" "$@"
Technically, it needs to be a little more sophisticated, as it should
insert "${monit...@]}" after the occurrence of a "--" parameter, if it
exists.
