I thought I saw something more definitive about the issue than the email here, like it was something that changed in smbclient argument parsing but I can't find it now. In my setup, debugging was complicated a bit by the fact that I have a domain and password server set up in my /etc/samba/smb.conf file that I want to be used by samba as a server on the same machine. However, smbclient also picks these up and will fail authentication against local accounts on the target machines unless pointed to a different config file with the -s option. -- Les Mikesell [EMAIL PROTECTED] - Take Surveys.

Could this be related to an smbclient problem reported earlier
where incrementals fail authentication? I'm attaching the
concluding email from that thread.

Thanks, Les, for the reply. I've been busy, and that's one of the
things I've checked.
What it comes down to, isSamba 3.0.23-1 broke my system. I'd setuid
the smbclient and mount.cifs commands on disk; it complained until I
removed that permission bit from those files. That didn't fix the
backuppc problems (though I held my breath as I tested again).
[It turns out smbmnt is /not/ based on "libsmb" - which is why samba was
complaining and bailing - nothing based on this library can be suid
anymore, fyi...so I simply setuid that executable. Bob's your uncle.]
Prepare for this upgrade, folks! They're trying to improve the world
over at Samba-land, and we're gonna be hurtin' until we figure all this out.
I still have no idea why logins only fail on incrementals.
I've upgraded to BackupPC v3.0.0beta0, but the smbclient command lines
for SMB-based incremental, full, and restore are the same as in past
versions :-/ No satisfaction there. I tested anyway, but you already
know how that story turns out.
I've been through the entire release notes for this version of Samba -
my prev version was 3.0.14a-2 (fedora core-4) - and there are literally
thousands of changes. My eyes are bleeding. Nothing jumped out at me,
no eureka moment...
We need a Linux kernel approach for samba, it would seem, where
even numbers and odd numbers are used for stable versions and for
massive changes, respectively - and those unstable versions are not
pushed out to every computer in the world!
Is anyone else running this version of samba? If so, is it working for
you? I'll work this problem from both endsif anyone has any info, I
would be grateful.
I'd go back, but the idea is that sofwtware changes are *for the
better*, and the Samba guys have as good a rep as anyone. I'm going to
try to fix this before I punt and downgrade.
I'm simply running a full backup on each machine that has not been
backed up for the last week or so! I would have punted days ago if
I didn't have this escape hatch.
Complicating things is the fact that I have this half-a-terabyte volume,
and it's 95% full, because I have it retaining nearly every backup I've
ever doneso I really reduced the retention figures, and now
BackupPC_trashClean is going nuts - it's already returned nearly 4
GB...and I have this feeling it'll be running all night - or all weekend :-)
More as it happens
Thought for the day: Fedora makes "trailblazers" of us all, I think,
when you have an untested combination of software - like BackupPC and Samba!

The only way a NT_STATUS_LOGON_FAILURE can occur is if the authentication for your user/pass is denied by SMB on the Windows XP box. If it's wrong for incremental, it's wrong for full backups as well, since it's the same setting. You might want to re-create the root$ share now that Use Simple File Sharing is turned off, as sometimes SMB likes to have its configuration recreated after certain settings change. Also, I would mention that if your username has an empty password associated with it, you may experience strange behavior using Samba as a transfer method, because users without passwords may be considered 'guests' through that protocol and arbitrarily be denied access to some directories.

[BackupPC-users] Found a Bug
Hi I have BackupPC 3.0.0.0 Beta3. I have a windows 2000 server with a few shares. I have set up backuppc to backup a share called root$. BackupPC will do a full dump of windows 2000 but refuses to do incremental backups. I have installed printer monitoring software on some of our servers that require me to turn of "Use simple file sharing" in windows Xp, when I do this full backups work on the Xp machines but suddenly incremental backups are refused. The reason: I have inserted the username and password required to make backups and it works, full and inrcremental. When turning "Use simple File Sharing" of - incremental backups fail with the message: "backup failed (session setup failed: NT_STATUS_LOGON_FAILURE)". My printer monitoring server require that "Use simple File Sharing" is turned off. Thanks - Take Surveys. Earn Cash.
