Samba: smbd fails to start

[ucfagls]

Hi,

Having reset-up a print server from installation disks today, I did something stupid and blindly copied the contents of /etc/samba from the previous installation into the new installation. (New installation is a fresh FC4 updated to latest updates using YUM)

Now smbd refuses to start (nmbd starts OK). I am currently using a blank smb.conf file and the smb.conf file from the old installation. testparm doesn't report any errors in the smb.conf from the old installation.

This is what I see in the shell when restarting smb:

/sbin/service smb restart

Shutting down SMB services:                                [FAILED]
Shutting down NMB services:                                [  OK  ]
Starting SMB services: /etc/init.d/functions: line 83:  2945 Aborted  $nice $*
                                                           [FAILED]
Starting NMB services:                                     [  OK  ]

And this is the relevant part of the log file:

Can anyone see what is wrong and how I can rectify this problem?

Thanks in advance,

Long story short?

/sbin/restorecon -v /etc/samba/secrets.tdb
/sbin/restorecon -v /etc/samba/smbpasswd

Fixed.

Thanks for this - will give it a try when I find a minute to look at this machine again. Will post back what I find, but TIA.

Actually, this fixed it in a short term kind of way. When the context was set for those files, it allowed Samba to start, but the actual shares apparently have to have a context applied to them as well, which was causing a lot of errors to pop up in the log with "The file '/home/raid5' could not be found." and from Windows clients, the share would appear in the network browser, but was unconnectable, reported as a permissions error. Not having enough time to fiddle with it at the time, I instead disabled SELinux for samba. I was really racking my head over this one too, because I've set up Samba a lot of times, and the idea that somehow Share level security on a 777'd directory structure, with public and guest enabled was still somehow causing permissions errors drove me nearly mad.

I ended up simply disabling it with
'setsebool -P smbd_disable_trans 1'

Maybe I'll play with it some more when I get back from my trip. I'm very interested in SELinux, but I have yet to find a good solid set of resources to help identify problems with it.
