Description Chris Recker 2010-01-22 21:23:37 UTC
Summary:

SELinux is preventing /usr/bin/python "connect" access.

Detailed Description:

[smoltSendProfil has a permissive type (smoltclient_t). This access was not
denied.]

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