Re: Trying to set context on a FIFO for nut_upsmon_t process

Robert,

If your application fails due to selinux policy, you could check /var/log/audit/audit.log.
If the audit.log contains denial, please post or attach the log here.
It should show what kind of policy your application needed in order to execute it.

SELinux is not allowing me to set the needed context on a FIFO that will be written by a nut_upsmon_t process. Runnin sesearch to find suitable types yields:
   allow nut_upsmon_t nut_upsmon_t:fifo_file { append getattr ioctl lock open read write };
But, when I try to run "chcon -t nut_upsmon_t /path/to/fifo" I get "permission denied" and an SELinux alert than complains
   If you want to change the label of .alertFIFO2 to nut_upsmon_t, you are not allowed to since it is not a valid file type.
   Then you must pick a valid file label.
   Do
   select a valid file type.  List valid file labels by executing:
   # seinfo -afile_type -x
That returns info for files, not FIFOs.

Once again, SELinux is causing me more problems than any virus would.
