Description Dima Tsozik 2010-03-21 22:16:44 UTC

SELinux is preventing /usr/bin/nautilus "execute" access on linux.bin.

Detailed Description:

SELinux denied access requested by nautilus. It is not expected that this access
is required by nautilus 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

To the roles directory.

Dima did you intend to use confined users?

Comment 2 Dima Tsozik 2010-03-22 23:56:44 UTC
No, I incidentally added my user name to the list of SELinux policy user templates. Yesterday I removed my user name from this list and haven't seen any issues with this host since then,
 Thank you,
