smbclient (1.9.18p3) dies or needs killing when used for backups (via Amanda)
Has anyone noticed that there appears to be a few
problems with regards to Samba and in particular the
usage of smbclient, which can do one of the following :
1) Complete & udder death of the NT networking subsystem
(which requires a reboot to cure)
2) smbclient appears to lose its connection with the
host being contacted and eventually needs to be
killed.
I'm not too sure how to go about trouble-shooting
the problems above, and I'm not too sure if they
are even related to each other. But I do know that
when I try to backup even 5 NT boxes via Amanda,
that at least one will fail.. I ran backups again
last night, and below is just the top of the output
that was stuffed into my mailbox (of about 14Mb).
Now, in this particular case, notice that two
instances of smbclient failed to complete -- one with
a data timeout (see #2 above), and the other I'm not
real sure about it.. The "strange" lines are normal,
and I'm not concerned about them at this point in time!
If ANYONE has any ideas on how to proceed, I'd be
interested in hearing it! Keep in mind that I know
very LITTLE about the SMB protocol, but perhaps for
the timeout problem, I should be specifying the
keepalive feature to be used -- I currently am not
using it. Also, I've attached my current top portion
of my smb.conf file.

See http://www.eng.auburn.edu/users/cartegw/samaba_ntdom_faq.html for a draft of a NTDOM FAQ. Only catch is that you have to set "encrypt passwords = yes" which will require you to keep a separate list of accounts on the UNIX box. Hope this helps, j- ________________________________________________________________________ Gerald ( Jerry ) Carter Engineering Network Services Auburn University jerry@eng.auburn.edu http://www.eng.auburn.edu/users/cartegw "...a hundred billion castaways looking for a home." - Sting "Message in a Bottle" ( 1979 )

It was sort of an all or none situation. Either all validation is done via an external PDC, or all via NIS, or all via smbpasswd, etc...> PLEASE Help us! :) People who have accounts on our PDC, but aren't in our > shadow password can't login right now.________________________________________________________________________ Gerald ( Jerry ) Carter Engineering Network Services Auburn University jerry@eng.auburn.edu http://www.eng.auburn.edu/users/cartegw "...a hundred billion castaways looking for a home." - Sting "Message in a Bottle" ( 1979 )
