Public bug reported: Binary package hint: samba
Our environment uses a CUPS server that is separate from the machine running Samba; the Samba machine has an /etc/cups/client.conf with the ServerName of the CUPS server. In this setting, Samba does not notice when you add or remove a CUPS printer, although 'lpstat -v' and so on on the machine running Samba will show the changed printer list. Reloading Samba (smbd) does not change this situation; only restarting smbd makes Samba update the printer list. It is possible that this bug also happens if the CUPS server is running on the same machine as the Samba server, but I have not tested that. Ubuntu release: Ubuntu 10.04 LTS 32-bit x86, with all current updates. Samba version: 2:3.4.7~dfsg-1ubuntu3.6 CUPS version: 1.4.3-1ubuntu1.3 (This probably reproduces on all architectures, but I haven't tested.) How to reproduce: - configure a CUPS server machine and set up a printer. - install a stock Ubuntu 10.04 machine. Create an /etc/cups/client.conf on it that has 'ServerName <IP-of-CUPS-server>'. Verify that Unix printing works. - Install Samba: 'apt-get install samba smbclient' - edit /etc/samba/smb.conf to add 'printcap cache time = 10' to the '[ global ]' section. Restart Samba. - Use 'smbclient -L localhost' to verify that you see the printer from your CUPS server. - add a printer to your CUPS server. Wait 30 seconds and run 'smbclient -L localhost' again, and see that it does not show the new printer. 'lpstat -v' and printing to it from Unix will work, though. - optionally, 'reload smbd' and repeat the 'smbclient -L localhost' to demonstrate that the reload did not change the situation. - 'service smbd restart', repeat 'smbclient -L localhost', and the new printer is now present. - delete the printer on the CUPS server, and rerun 'smbclient -L localhost'; Samba still lists the printer. (The convenient way to add a new printer is just to add a new name for your existing printer, duplicating destination settings and so on.) What I expected to happen: 'smbclient -L localhost' lists the new printer when it is added and does not list it when it is removed. This behavior is a regression from Ubuntu 8.04 (samba version 3.0.28a-1ubuntu4.14). I have not tested intermediate non-LTS releases to determine where the problem first appears. Since your Samba bug reporting page specifically asks for this information: $ dpkg-query -W -f='${Package} ${Version} ${Source} ${Status}\n' | grep samba libsmbclient 2:3.4.7~dfsg-1ubuntu3.5 samba install ok installed libwbclient0 2:3.4.7~dfsg-1ubuntu3.5 samba install ok installed samba 2:3.4.7~dfsg-1ubuntu3.5 install ok installed samba-common 2:3.4.7~dfsg-1ubuntu3.5 samba install ok installed samba-common-bin 2:3.4.7~dfsg-1ubuntu3.5 samba install ok installed smbclient 2:3.4.7~dfsg-1ubuntu3.5 samba install ok installed The Samba log files in /var/log/samba contain no information; log.smbd and log.nmbd have only startup notices, and the log.<client> file is empty (0 length). I can include them if you really need them. I'm attaching 'smbclient -L' output, and also /etc/samba/smb.conf and 'testparm -s' output, although the latter two will probably be mostly pointless (since I've given instructions on how to construct the smb.conf above). ** Affects: samba (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787755 Title: Samba does not notice added or removed CUPS printers -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
