Description Jimmy Rentz 2010-11-28 21:27:24 UTC
Summary:

SELinux is preventing /sbin/ifconfig "search" access for.
NOTE: For some reason ddclient was left out of the message.  I am guessing this is why I didn't see ddclient mentioned as the target RPM package in the sealert output.

Detailed Description:

SELinux denied access requested by ifconfig. It is not expected that this access
is required by ifconfig 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 Miroslav Grepl 2010-11-28 23:40:02 UTC
Jimmy,
could you execute

# semanage permissive -a ddclient_t

Try to use ddclient and after that execute

# ausearch -m avc -ts recent

and please attach AVC messages which you are seeing. Thanks.
