Possible to edit multiple DNS zones

[andrewm]

I'm about to move servers and I want to lower the TTL value on all the domains in my WHM - there are about 100.

Is there any way of modifying all these at once, or am I going to have to edit each DNS zone manually?

Thanks

When I need to do things like that, I just download the files, open them in a good text editor like cutehtml or notetabpro, and use search/replace, then upload the new files. Takes a total of about 5 minutes for 100 files.

If you prefer from shell, see this thread.

Thanks.

Which files do I need to download though - all the named.db files?

Yes
Should be /var/named/[domain].db

Just make sure you upload and download in ascii not binary.

From shell:

(first, backup all of your files

then:

find /var/named -type f -exec \
sh -c 'gawk "$0" "$1" > "$1.tmp"; mv "$1.tmp" "$1"' \
'{gsub("oldvalue","newvalue"); print $0}' '{}' \;


Just replace oldvalue and newvalue with the appropriate values.

So, if you wanted to change "expire" from 3600000 to 600 .....

find /var/named -type f -exec \
sh -c 'gawk "$0" "$1" > "$1.tmp"; mv "$1.tmp" "$1"' \
'{gsub("3600000","600"); print $0}' '{}' \;

YOU ARE AWESOME!!

how about:

replace '36000' '6000' -- *.db

Lots easier and command line. No script needed.

Bear in mind that if you touch a zone file you should always increment the SERIAL number too.
