amanda not using smbclient for samba clients?
2007-11-28 01:49:09
I've been through the docs a bunch of times to try to figure out what
exactly I'm doing wrong but either I'm not doing anything wrong
(unlikely) or there's something I keep thinking is right but isn't (more
likely). When I run a check on the Amanda setup, it queries the samba
client (a Mac OS X computer) but tries to communicate via Amanda ports
rather than trying to mount and check the samba share. Here's the
output as well as disklist and amanda.conf. I'm guessing that the
problem is the disklist but the problem is non-obvious to me.
