Details

Description:

I'm using the line:
hosts: files dns wins
in '/etc/nsswitch.conf' file.

I'm starting the 'samba' daemon and I've changed the file '/etc/conf.d/samba' to use this line:
SAMBA_DAEMONS=(smbd nmbd winbindd)

When I try to resolve a hostname in a terminal with some command like 'ping', 'ssh', etc, with the package 'samba-3.5.0-1' ('/lib/libnss_wins.so' ?) the terminal just outputs 'Aborted'.

I downgraded to the following packages:
pacman -U samba-3.4.6-1-i686.pkg.tar.gz smbclient-3.4.6-1-i686.pkg.tar.gz

And it started working nicely.

Reverting to the lastest version of these packages the problem comes back.

As a work around I'll be using the older version cited above.


Please ask if more information is needed.

I've installed abs and built the lastest version of 'samba' using the following source tar:
http://us1.samba.org/samba/ftp/stable/samba-3.5.1.tar.gz
And the problem persisted with this newer version.

Also this will make nautilus report a dbus error when trying to navigate a samba share in another machine. Log reports that

gvfsd-smb[2864]: segfault at c35dec79 ip b7749068 sp b67e4b60 error 5 in libsmbclient.so.0[b72e1000+5a2000]

Force a downgrade to 3.4.6 solves the ping problem and the nautilus/dbus problem (making use of windows share possible again).

Last update to samba and smbclient blocks me to use internet or any command that alows use of internet (will produce an "Aborted" message on ping or pacman for example)

Still forcing downgrade to 3.4.6 works. (at least until a fix is available in repositories)

Upgrading to gnome 2.30 forcess a samba update. The samba update is still buggy.

Workaround: delete "wins" parameter in /etc/nsswitch.conf

The net will be normal again, but you can't resolve windows names anymore, so some users (mostly users/admins that need compatibility with windows machines) are screwed if they update gnome or samba).

The issue is fixed in samba 3.5.2-1 in testing repository.
