I have the Bacula backup system running and SELinux is interfering.

The problem arises when Bacula runs a script that invokes /usr/bin/hostname before one of the backups.

12-Apr 00:05 dir_backup JobId 122: BeforeJob: /usr/local/sbin/sshbacula: line 13: /usr/bin/hostname: Permission denied

This succeeds when SELinux is in permissive mode.

It is a very minor problem but I cannot fix it without running SELinux in permissive mode or by running Bacula unconfined entirely.

How do I allow Bacula to execute the hostname binary?

  • What was in the audit log? – Michael Hampton Apr 11 '18 at 22:20
  • I have not checked but I am pretty sure that it is because /usr/bin/hostname has the hostname_exec_t context and Bacula is then not allowed to run it. I'm not sure if possible, but can I somehow allow Bacula access to hostname_exec_t? – Lasse Halberg Haarbye Apr 14 '18 at 01:28
  • Let's not make wild guesses. You can get a good answer and know you have solved the problem if you actually get the real data from the audit log and work with that. – Michael Hampton Apr 14 '18 at 01:56
