Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Update zone file Serial numbers

Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc.

Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this.

Make sure your server's date is correct, otherwise insert your own serial number.

rndc reload

should usually follow this command.

What others think

This is cool. But I have been using emacs (zone-mode) for this purpose, incase if someone did not know. :. When ever you save the db file emacs automatically increment the SOA number.

Nice, i think i will have to give emacs a try for editing individual zone files!

I find this is useful for doing a mass update, which sometimes the situation can call for.
