Hello, sorry for the late answer, I just try to catch up with my mailing lists …

I did write an init script for eisfair-1¹ roughly one year ago.

I assume like this: * run the daemon * start at least two client connections from somewhere * see the process list * kill the deamon * see the process list again > A bootscript restart or stop option should do the same; it should send > SIGTERM to all the rsync server processes. Why should it? Don't the worker processes terminate when their transmissions are complete? I would assume it's enough to restart the "main" daemon. > Similarly a bootscript status > option should report not only the status of the process recorded in the PID > file but also of any worker processes. Interesting thought. How would you implement this? > This seems so obvious I am surprised not to have found comprehensive prior > art so wonder if I have overlooked something basic ... ? I don't find it that obvious, as explained above. I would just restart the daemon in case of a changed config for example to make new connections possible. I wouldn't touch running rsync operations, because these must not be restartet, must they? If you're interested in my script, you could extract it from http://www.pack-eis.de/dl.php?l=9592/rsync.tar.bz2 – this archive contains a / folder structure, you should find the script in /etc/init.d 8-) Greets Alex ¹ http://www.eisfair.org/ -- »With the first link, the chain is forged.
