Description Louis van Dyk 2010-01-26 20:48:10 UTC

SELinux is preventing certwatch (certwatch_t) "write" to ./cache (var_t).

Detailed Description:

SELinux denied access requested by certwatch. It is not expected that this
access is required by certwatch and this access may signal an intrusion attempt.
It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for ./cache,

restorecon -v './cache'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
( Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (
against this package.

I have a USB printer: Samsung CLP-310.  I have installed the Samsung "UnifiedLinuxDriver_1.00.tar.gz" driver for the printer.  When I submitted the print job, this error appeared.

You are reporting an F10 problem on an F12 machine.

Comment 4 Louis van Dyk 2010-01-28 10:57:50 UTC
My apologies.  I was running F10 on a machine and ran preupgrade to get it to F11.  Then I ran preupgrade to get it to F12.  When I installed the printer driver and printed my first job I got the error.  So I am puzzled as to why it asked for this, but I am sorry for wasting your time.

Comment 5 Daniel Walsh 2010-01-28 14:01:29 UTC
No problem.  Just go through setroubleshoot and delete the old avc messages. I am working on an udpdate to setroubleshoot to do this automatically.
