SELinux causes web server response timeouts on the Unitrends system

SUMMARY

This article provides troubleshooting for when SELinux causes web server response timeouts on the Unitrends system.

ISSUE

Make sure that SELinux is disabled for proper operation of the Unitrends appliance. If the Red Hat SELinux feature is enabled, it will cause the web service responses not to be sent, and accessing the Unitrends interface will time out. This is disabled at Unitrends by default, but sometimes this can be re-enabled by certain CentOS or Red Hat Enterprise Linux core update packages.

To resolve this error:

  1. Edit the /etc/sysconfig/config file so that SELINUX=disabled, then reboot.

Here is a script to automate this procedure:

sed -i -e 's/^SELINUX=[a-z]*/SELINUX=disabled/' /etc/sysconfig/selinux

Note: With Unitrends release 7.2, this will be automated in the unitrends-rr-7.2.0*.rpm installation.
