SELinux is preventing /usr/bin/python access to a leaked /var/asl/tmp/asl.lock
file descriptor.

Detailed Description:

[denyhosts.py has a permissive type (denyhosts_t). This access was not denied.]

SELinux denied access requested by the denyhosts.py command. It looks like this
is either a leaked descriptor or denyhosts.py output was redirected to a file it
is not allowed to access. Leaks usually can be ignored since SELinux is just
closing the leak and reporting the error. The application does not use the
descriptor, so it will run properly. If this is a redirection, you will not get
output in the /var/asl/tmp/asl.lock. You should generate a bugzilla on
selinux-policy, and it will get routed to the appropriate package. You can
safely ignore this avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ

Comment 1 Daniel Walsh 2010-06-16 17:09:16 UTC
This looks like you edited the denyhosts.py file?

What is /var/asl?
