I have some 80 sites hosted on my Raq4r under the same IP address. I now have to change this as I am getting a new IP.... rather then go to each individual site and change the IP from the GUI, is there a faster way I can do this so that it will change all 80 at once?
If the old IP is the MAIN SITE IP, they will change automatically when you change the main site IP. If they are a different IP than the main site IP, you'll need to do it manually through the GUI.
If you run your own DNS, you can edit the /etc/named/records file directly with a search and replace to change it (be sure to back it up first), then save changes in the GUI to reload... so that will save you a little time... but you're stuck doing it the long way as far as the actual virtual sites go.
