Red Hat Bugzilla – Bug 617208
printers are not found after system boot
Last modified: 2015-05-04 21:20:36 EDT
Description of problem:
When I boot-up the system and I enter gnome printing dialog, I do not see any of network printers. I must do "sudo service cups stop; sudo service cups start" and then printers are there and all works just fine. This worked just fine in F12. I had the same problem in F10 or F11 (not sure).
I have only "BrowsePoll ourcupserver:631" line added into default /etc/cups/cupsd.conf
Change the LogLevel in /etc/cups/cupsd.conf to debug
and next time you boot-up please look into /var/log/cups/error_log
if you can find some useful info.
E [10/Jan/2011:14:54:11 +0100] [cups-polld cups.brq.redhat.com:631] Unable to connect to cups.brq.redhat.com on port 631: Host name lookup failure
My wild guess here is that cupsd starts before network parameters are set and doesn't get the new settings when NM configures the network. Adding res_init() where cupsd tries to connect might help. Or implement a support for NetworkManager ;)
btw, I use: cups-1.4.6-1.fc14.x86_64
*sigh* We already call res_init() in all the documented situations where we ought to, and in some that are not documented especially for glibc. Maybe there's another undocumented situation now. :-(
It's really sad that glibc can't handle this on it's own, but I'm no glibc specialist, so there might be a reason... So, do you need some additional info?
No need, I've managed to reproduce it here. It looks like getaddrinfo() now returns EAI_NONAME instead of EAI_NODATA in this situation.
Should be fixed in cups-1.4.6-2.fc13.
cups-1.4.6-2.fc13.x86_64 works fine, thx!
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '13'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 13's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 13 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
