Dealing with a security problem on Fedora 16. These are instructions to fix problem. How do I change the label? [I am a new user.

"SELinux is preventing /usr/bin/brprintconf_dcpj125 from write access on the directory /opt/brother/Printers/dcpj125/inf.
***** Plugin catchall_labels (83.8 confidence) suggests ********************
If you want to allow brprintconf_dcpj125 to have write access on the inf directory
Then you need to change the label on /opt/brother/Printers/dcpj125/inf
restorecon -v '/opt/brother/Printers/dcpj125/inf'"

If this is some proprietary software from Brother, I'm guessing they did not include security context with their files. Since you're running SELinux, this creates an issue. Restorecon would only work if there was a context to restore to, which is doubtful. You'll have to change the context to something appropriate; see the man page for chcon.

the SE error masage informs you to the fix
the fix in the massage works 99.999% of the time
note the SINGLE ' quote ' mark used

Just in case it doesn't work minimally provide the complete /var/log/audit/audit.log message, plus 'rpm -qf /usr/bin/brprintconf_dcpj125' plus 'ls -alZ /usr/bin/brprintconf_dcpj125 /opt/brother/Printers/dcpj125/inf'.
