I've finally decided to see if I can get rid of all
my SELinux errors. A great help in this was installed the

This is on FC7...

I am unable to get rid of the following error
regarding fetchmail not being able to access .fetchmailrc in home
directories.

I have used the suggested commands to "relabel"
things... but the error messages persist. :-(

What am I missing?

Summary
SELinux is preventing the /usr/bin/fetchmail from
using potentially mislabeled files (/home/don/.fetchmailrc).
Detailed Description
SELinux has denied /usr/bin/fetchmail access to
potentially mislabeled file(s) (/home/don/.fetchmailrc). This means that SELinux will not allow /usr/bin/fetchmail to use these files. It is common for users to edit files in their home directory or tmp directories and then move (mv) them to system directories. The problem is that the files end up with the wrong file context which confined applications are
not allowed to access.
Allowing Access
If you want /usr/bin/fetchmail to access this files,
you need to relabel them using restorecon -v /home/don/.fetchmailrc. You might want to relabel the entire directory using restorecon -R -v
/home/don.

Don,

I am no expert here on selinux, but when I have run
into problems with it, I try the suggestions:

# restorecon -v /home/don/.fetchmailrc.

Did that.. it was suggested in the message fro the troubleshoot package...

You might want to
relabel the entire directory using
# restorecon -R -v /home/don.


Ditto....

If this do not work like you are stating, the next
step is to try the two commands as su - SuperUser
Mode: # touch ./autorelabel
# reboot


Ah ha! Thank you.... I did that last night, and this morning those message have stopped.

Thank you. :-)
and if that does not work check the selinux policy to
see that it is the latest one. Selinux is difficult
many times, but there are some kind users on this list
and the fedora-selinux-list that are very helpful. You may also read the pages on the Wiki
http://fedoraproject.org/wiki/SELinux

http://fedoraproject.org/wiki/SELinux/Troubleshooting

If you have set the selinux mode to permissive and
then made the respective changes that the
setroubleshoter encouraged you to do and then started
selinux in enforcing mode and you get denied avcs
again, you may need to file a bug report against the
package(s)

fetchmail-6.3.7-2.fc7 or Policy RPM: selinux-policy-2.6.4-40.fc7

Regards,

Antonio
