Package: cups-browsed Version: 1.11.6-3 Severity: normal We have a central cups print server (and one client offering a queue for a not network-connected printer) and about 50 identically configured clients running a current stable using it to print. On one specific client sometimes all printer queues stop working, giving the error message 'No destination host name supplied by cups-browsed for printer "name of the queue", is cups-browsed running?'. Restarting the cups and cups-browsed services does not fix the behaviour; most of the times a reboot does, but not always.
Comparing the two browsed debug logs of the affected and and unaffected client I notice after printing (or trying to print) a test page, that the affected one is missing the lines, showing that the cups server contacted it. I'll attach the excerpt of the cups debug log showing the last connection attempts (of forty before cups gives up) below. Changes to queues on the server get communicated through to cups by cups-browsed so communication in that direction seems to be working. Both cups and cups-browsed on the client are currently running with the debug logs enabled, so if you need any more info I'll hopefully be able to provide it. Probably just a coincidence but I'll mention it: The user of the affected client is the only one of ours that's running KDE as desktop. -- System Information: Debian Release: 9.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-5-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages cups-browsed depends on: ii cups-daemon 2.2.1-8 ii init-system-helpers 1.48 ii libavahi-client3 0.6.32-2 ii libavahi-common3 0.6.32-2 ii libavahi-glib1 0.6.32-2 ii libc6 2.24-11+deb9u1 ii libcups2 2.2.1-8 ii libglib2.0-0 2.50.3-2 ii libldap-2.4-2 2.4.44+dfsg-5+deb9u1 ii lsb-base 9.20161125 Versions of packages cups-browsed recommends: ii avahi-daemon 0.6.32-2 cups-browsed suggests no packages. -- Configuration Files: /etc/cups/cups-browsed.conf changed: LogDir /var/log/cups DebugLogging file BrowseRemoteProtocols cups BrowseAllow 141.66.176.24 BrowseAllow cups.zblmath.fiz-karlsruhe.de BrowsePoll 141.66.176.24 BrowsePoll cups.zblmath.fiz-karlsruhe.de -- debconf-show failed /var/log/cups/error_log: D [17/Jan/2018:12:56:41 +0100] [Client 52] Closing connection.
