Try the --timeout option, which will make rsync exit if no progress is made for a specified time period. This is probably easier and more reliable than coding your own timeout. > The command "ps ax | grep 'rsync' | grep -v grep" is not enough because > the rsync and ssh process can be running but the connection to the > remote server is no longer ESTABLISHED and the backup is no longer > proceeding. > > Then perhaps the command "netstat -A | grep '192.168.1.10' | grep > 'ESTABLISHED' | grep -v grep" would be helpful.

If you decide to go this route, you can get the pid of the ssh process holding the connection by passing --program to netstat and then check whether its parent (for the local ssh) or child (for the remote ssh) is an rsync process. -- Matt -- Please use reply-all for most replies to avoid omitting the mailing list.
