Description edo 2009-12-01 09:45:17 UTC
Summary:

SELinux is preventing /usr/bin/kismet_server "read" access on psched.

Detailed Description:

SELinux denied access requested by kismet_server. It is not expected that this
access is required by kismet_server 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

You can add these rules for now using

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