Symptoms

Logs /var/log/messages shows the following warning when Named is started:

    named[12326]: could not open entropy source /dev/random: file not found
    named[12326]: using pre-chroot entropy source /dev/random

Cause

Named is running in chroot environment and system cannot find /var/named/run-root/dev/random file.

Resolution

This warning may be ignored, because system will use /dev/random file instead. But it want to avoid this warning, please create /var/named/run-root/dev/random as below:

    [root@dns2 ~]# mkdir -p /var/named/run-root/dev
    [root@dns2 ~]# mknod /var/named/run-root/dev/random c 1 8
    [root@dns2 ~]# chmod 644 /var/named/run-root/dev/random
