Description Douglas E. Warner 2010-07-25 15:30:17 EDT
The new version of syslog-ng (bug#598961) is having these errors show up in the applet:


Summary:

SELinux is preventing /sbin/syslog-ng "create" access on syslog-ng.ctl.

Detailed Description:

SELinux denied access requested by syslog-ng. It is not expected that this
access is required by syslog-ng 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:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Douglas E. Warner 2010-07-25 15:36:22 EDT
There are temp packages here (v3.1.1):
http://www.silfreed.net/download/repo/packages/syslog-ng/

I'll be committing the changes to rawhide branch shortly since things are looking good other than the selinux permissions.
Comment 2 Daniel Walsh 2010-07-26 07:57:46 EDT
Fixed in selinux-policy-3.8.8-5.fc14
