I have a debian lenny server using webmin to manager bind 9 dns server.
I need to change the A records for 50 domains.
Is there a way to do in bulk mode without modify each domain ?
John underestimates Webmin.
Browse to the BIND DNS module in Webmin
Select the zones you want to update in the "Existing DNS Zones" (check the boxes beside them)
Click "Update Records in Selected"
On the resulting form, set the following:
Record type to update: Address (this is the default)
Current value to change: address you want to alter
New value: new IP address
Click "Change Records"
You may also need to click the Apply changes link in the top right corner of the BIND module home page in order to reload the BIND zone files after making the change.
Additional documentation for the BIND module in Webmin can be found here: http://doxfer.com/Webmin/BINDDNSServer
I don't believe this is possible using a simplistic interface such as Webmin provides. Easily enough done at the command line though. Using whatever tools you're comfortable with do a search and replace.
