Description Oliver 2009-11-29 21:12:19 UTC
Zusammenfassung:

SELinux is preventing /usr/libexec/cups-pk-helper-mechanism "connectto" access
on /var/run/cups/cups.sock.

Detaillierte Beschreibung:

[cups-pk-helper- hat einen toleranten Typ (cupsd_config_t). Dieser Zugriff wurde
nicht verweigert.]

SELinux denied access requested by cups-pk-helper-. It is not expected that this
access is required by cups-pk-helper- 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.

Zugriff erlauben:

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

Comment 1 Daniel Walsh 2009-11-30 21:40:04 UTC
Were you running some cups program as a user rather then as a service?

Comment 2 Oliver 2009-12-01 06:28:03 UTC
I'm not sure. The probleme appears since i was trying to install a third party printer driver by samsung.

Comment 3 Daniel Walsh 2009-12-01 14:23:45 UTC
Has it happened since?  And does everything seem to work correctly now?

You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
