SELinux is preventing /usr/sbin/sshd "name_bind" access .

Detailed Description:

[sshd has a permissive type (sshd_t). This access was not denied.]

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

Comment 1 Daniel Walsh 2010-04-22 17:22:42 UTC
Why is sshd trying to bind to port 8080?

Comment 2 bugzilla 2010-04-22 17:28:20 UTC
I Guess it was a remote tunnel I created, that caused this error.

Comment 3 Daniel Walsh 2010-04-23 12:27:18 UTC
Sorry, I now see that we are allowing this in F13.


I think you want to grab the ssh.if and maybe ssh.te from F13 and back port to F12.
