Such a protocol exists and is usable (I tried it). Create a named console n the DIR config with the same name as the client (typically client-fd). You can use ACLs tolimit the permissions this console has to the barest minimum. Then use the 'setip' command from a console installed on the client. I'm pretty sure you could integrate this into a logon script for windows. > It's not something I have to deal with, because my stuff is all fixed IPs. Dynamic IPs and automatically updating DNS is probably the best solution. It doesn't work with Bacula only, but allows other network programs to find the clients they need.
