[Pkg-samba-maint] Bug#612672: samba: fails to set up IPC$ share due to canonicalize_connect_path failure

[Alan Schwartz]

Package: samba
Version: 2:3.5.6~dfsg-3
Severity: important


Upgraded lenny to squeeze. Samba configuration that used to work
on lenny no longer works. Replaced it with a minimal configuration,
still doesn't work.

Symptoms: smbclient -L localhost does not list shares, and log file
gives an error message related to IPC$ share's path:

# smbclient -L localhost
Enter root's password: <enter>
Anonymous login successful
Domain=[ALANSZ] OS=[Unix] Server=[Samba 3.5.6]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME

Logfile /var/log/samba/log.smbd reports:

[2011/02/09 15:16:49.532999,  0] smbd/service.c:988(make_connection_snum)
  canonicalize_connect_path failed for service IPC$, path /tmp

The /etc/samba/smb.conf is, in its entirety:

[global]
workgroup = ALANSZ
passdb backend = smbpasswd
netbios name = TALA

[araw]
path = /opt/shared
read only = No

This configuration file passes testparm:
# testparm -s /etc/samba/smb.conf
Load smb config files from /etc/samba/smb.conf
rlimit_max: rlimit_max (1024) below minimum Windows limit (16384)
Processing section "[araw]"
Loaded services file OK.
Server role: ROLE_STANDALONE


Online searching finds several reports of this problem potentially
related to the value of TMPDIR when smbd is started. The new squeeze
/etc/init.d/samba unsets TMPDIR, which seems like the right thing
to do.

/tmp exists on this system with the usual debian permissions.
I have also tried creating /root/tmp, /var/lib/samba/tmp,
and /var/run/samba/tmp with similar permissions, to no avail.
