>Detailed Description:

>SELinux is preventing iptables (iptables_t) "append" to
>/var/log/cobbler/cobbler.log (var_log_t). The SELinux type var_log_t, is a
>generic type for all files in the directory and very few processes (SELinux
>Domains) are allowed to write to this SELinux type. This type of denial usual
>indicates a mislabeled file. By default a file created in a directory has the
>gets the context of the parent directory, but SELinux policy has rules about the
>creation of directories, that say if a process running in one SELinux Domain
>(D1) creates a file in a directory with a particular SELinux File Context (F1)
>the file gets a different File Context (F2). The policy usually allows the
>SELinux Domain (D1) the ability to write, unlink, and append on (F2). But if for
>some reason a file (/var/log/cobbler/cobbler.log) was created with the wrong
>context, this domain will be denied. The usual solution to this problem is to
>reset the file context on the target file, restorecon -v
>'/var/log/cobbler/cobbler.log'. If the file context does not change from
>var_log_t, then this is probably a bug in policy. Please file a bug report
>(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against the selinux-policy
>package. If it does change, you can try your application again to see if it
>works. The file context could have been mislabeled by editing the file or moving
>the file from a different directory, if the file keeps getting mislabeled, check
>the init scripts to see if they are doing something to mislabel the file.
>
>Allowing Access:
>
>You can attempt to fix file context by executing restorecon -v
>'/var/log/cobbler/cobbler.log'
>
>The following command will allow this access:
>
>restorecon '/var/log/cobbler/cobbler.log'
