Description Arvid Requate univentionstaff 2012-11-14 17:39:22 CET
Bei allen Samba4 CLI-Tols erhält man aktuell die folgenden zwei Zeilen im Output:

WARNING: No path in service IPC$ - making it unavailable!
NOTE: Service IPC$ is flagged unavailable.

Es sollte grprüft werden, ob der IPC$ share noch notwendig ist (Vermutlich nicht mit RC2, wo der smbd mit /var/lib/samba/private/smbd.tmp/fileserver.conf gestartet wird).

Generell sollte man dann mal die base.conf und smb.conf Templates nach nicht mehr unterstützten Optionen durchsehen und dafür ggf. separat Bugs anlegen:

Comment 1 Arvid Requate univentionstaff 2013-02-11 20:05:36 CET
Behoben in univention-samba4 in errata3.1-0 und ucs3.1-1.

Advisory: 2013-02-07-univention-samba4.yaml
Comment 2 Arvid Requate univentionstaff 2013-02-18 18:23:20 CET
Trat vorher z.B. bei "samba-tool ntacl sysvolcheck" auf.
Comment 3 Stefan Gohmann univentionstaff 2013-02-21 16:21:36 CET
As discussed, please move it to UCS 3.2.

Comment 6 Arvid Requate univentionstaff 2015-01-22 16:28:48 CET
/etc/samba/base.conf of univention-samba4 defines a share [IPC$] which doesn't have an associated "path" option. This share definition was required in the early "s3fs" configuration of Samba4. Now it is probably obsolete. The Samba config parser checks are now more strict and output this message. It can be ignored and should be removed at some point.

Thanks for the background info!
Snitched your description and placed it in the SDB article <http://sdb.univention.de/1297> ;)

This message is logged to log.samba 4 times every 10 minutes, we should fix that:

Please fix this, it clutters every log file!
Comment 10 Michael Grandjean univentionstaff 2015-09-17 16:52:52 CEST
This is also quite annoying to explain in technical trainings and workshops.

Comment 12 Arvid Requate univentionstaff 2015-10-06 22:58:30 CEST
Ok in cases where samba4/service/smb=s3fs (aka the current default), the [IPC$] share definition is not written any longer.

UCS 4.1-0 changelog adjusted accordingly.
