Thread: cPanel Tech Advisory: BIND: Red Hat and CentOS

There is a bug in version of the BIND DNS server distributed by RedHat and CentOS that might cause BIND to have problems restarting. cPanel has released an auto-fixer for this problem.

Recent versions of Bind distributed by RedHat and*CentOS enable strict zone checking at startup time. This setting can potentially cause problems for Bind users with a large number of zone files or syntax errors in individual zone files. In these circumstances, users may experience an inability to restart Bind after a shutdown.*cPanel has produced and distributed an autofixer for this condition. This repair will run automatically on all systems with updates enabled. However, cPanel checks only occur at specific times and depending upon update schedules, users experiencing issues restarting Bind may benefit from manually executing the code to disable strict zone checking.

You may safely execute the autofixer at your discretion by running the following command:**

/scripts/autorepairbind_disable_checkzone

There are 2 ways to manually restart BIND to test for this problem. One way is by typing this command into the shell as root:

Code:

service named restart

The other way is by going to WHM --> Restart Services --> DNS Server (BIND/NSD)

If it restarted without a problem, you will see this:

Stopping named: . [ OK ]
Starting named: [ OK ]

If it fails, you will see this:

Stopping named: . [ OK ]
Starting named: [ FAILED ]

I wonder if this is what was causing me issues on one of my servers.

I had the same problem .. may be they would release some patch

They did. If your cPanel hasn't been upgraded yet, do so with this command from the shell:

Code:

/scripts/upcp

Then run this command:

Code:

/scripts/autorepairbind_disable_checkzone
