selinux does not like crontab :(, default_t, kde



Dear all,

I have resolved one problem(Not getting internet at startup by default), but have not fixed the crontab one and other(s):

This one does not go away :(


Summary:

SELinux is preventing crontab (admin_crontab_t) "read write" unconfined_t.

Detailed Description:

SELinux denied access requested by crontab. It is not expected that this access
is required by crontab 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) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

I can't modify my crontab file:

[olivares riohigh ~]$ crontab -l

Authentication service cannot retrieve authentication info
You (olivares) are not allowed to access to (crontab) because of pam configuration.
[olivares riohigh ~]$

if I disable selinux, I can modify it and view it, but not with selinux enabled.  

I got greeted with the following:


Summary:

SELinux is preventing access to files with the default label, default_t.

Detailed Description:

SELinux permission checks on files labeled default_t are being denied. These
files/directories have the default label on them. This can indicate a labeling
problem, especially if the files being referred to are not top level
directories. Any files/directories under standard system directories, /usr,
/var. /dev, /tmp, ..., should not be labeled with the default label. The default
label is for files/directories which do not have a label on a parent directory.
So if you create a new directory in / you might legitimately get this label.

Allowing Access:

If you want a confined domain to use these files you will probably need to
relabel the file/directory with chcon. In some cases it is just easier to
relabel the system, to relabel execute: "touch /.autorelabel; reboot"

Startup did not take the 20 seconds, it took like 8 to 10 minutes with the relabeling and still see the same things.  Is there an update that will fix this or do I have to disable selinux or boot in permissive in order to have a working machine.  

Please help this is no longer fun as it once was.

Regards,

Antonio
