Q. I’ve configured BIND named TSIG as documented here. It worked for some time, but my /var/log/messages got the errors as follows:

zone example.org/IN: refresh: failure trying master 71.22.11.22#53 (source 0.0.0.0#0): clocks are unsynchronized: 9 Time(s)
zone example.org/IN: refresh: failure trying master 71.22.11.22#53 (source 71.22.11.22#0): clocks are unsynchronized: 9 Time(s)

How do I fix these errors under Debian Linux 64 bit etch server?

Posted on in Categories , , , , , , , , , , , , , last updated July 18, 2008

I’ve nameserver like ns1.example.com and ns2.example.com. I’d like to provide Vanity DNS for each domain such as ns1.yourdomain.com and ns2.yourdomain.com.

How do I setup vanity DNS using BIND 9 under UNIX / Linux?
