Unable to print after upgrade from Fedora Core 5 to 6

I upgraded from Fedora Core 5 to 6 with Yum using the DVD image as a local repository. The printer is Canon iP4200 that is connected to a Windows XP machine on the local network. Before I upgraded to Fedora Core 6, I was able to print to the printer. Now when I print, cups says that the job is in "printing" status and stays that way indefinitely. Below is the output from /var/log/cups/error_log.

Code:

E [28/Oct/2006:12:31:11 -0400] [Job 121] Can't load /etc/samba/smb.conf - run testparm to debug it

E [28/Oct/2006:12:31:11 -0400] PID 9698 (/usr/lib/cups/backend/smb) stopped with status 1!

I tried testparm and it returned 0 indicating there is no error in smb.conf.

This is the permission settings on smb.conf:

Code:

-rw-r--r-- root root system_u:object_r:samba_etc_t /etc/samba/smb.conf

This is the boolean settings for SELinux:

Code:

# getsebool -a | grep cups

cupsd_config_disable_trans --> off

cupsd_disable_trans --> off

cupsd_lpd_disable_trans --> off

I am able to use smbclient to verify that the printer is available on the network.

Edit:
From /var/log/cups/error_log at an earlier time, there is another error message that appears to be important.

Code:

E [28/Oct/2006:12:27:58 -0400] Unable to set ACLs on root certificate "/var/run/

cups/certs/0" - Operation not supported

I am able to temporarily fix this when I set SELinux to permissive by using the command "setenforce 0", I am able to print. I will have to watch for news on SELinux rules on printing for a permanent fix.

Thanks.

For those of you who have the same problem, the bug is in SELinux and has been resolved in selinux-policy-2.4.3-9.fc6. See https://bugzilla.redhat.com/bugzilla....cgi?id=214839 for more detail.

I've updated to selinux-policy-2.4.6-13.fc6, and I still get this error... Any other ideas?

Are you getting the same errors in /var/log/cups/error_log as I did?

Yep, I'm getting the exact same error... Nothing has fixed it yet.

I'm also using selinux-policy-2.4.6-13.fc6 and had no problem with printing to that network printer. Check that /var/run/cups/certs/0 has the correct permissions and security context.

You should get this output when running the command as root:

Code:

# ls -lZ /var/run/cups/certs/0

-r--r-----  root sys user_u:object_r:cupsd_var_run_t  /var/run/cups/certs/0

If your output matches the above, then there is no problem with permissions and context of /var/run/cups/certs/0, and the problem is somewhere else. In this case, post the output of /var/log/audit/audit.log at the approximate time that you attempted to print.

Nope, I've got the following:

[root@Dingo plugins]# ls -lZ /var/run/cups/certs/0
-r--r----- root sys system_u:object_r:cupsd_var_run_t /var/run/cups/certs/0

How do I fix this?

Figured it out... Just used:

Code:

chcon -u user_u 0

And that fixed my printing issues!

Thanks
