Description Peter Belew 2011-02-22 00:58:01 UTC
SELinux is preventing /usr/bin/uptime from 'read' accesses on the file /var/run/utmp.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that uptime should be allowed read access on the utmp file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep uptime /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-02-22 09:35:40 UTC
Reading utmp file from apache is not something we want to support.

You have to add custom poliyc to allow this.

# grep uptime /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
