I'm having a brain freeze, and I hope someone can help me.

I host nameservers here, but some domains are on another server. What do I need to do (either in Ensim, or from the command line) to have my nameservers point to an IP address elsewhere?

Thanks,
Alden

My brain unstuck and I figured it out:
Go to DNS-->Zones in Ensim
Add Zone (add the domain name and use the name servers you have)
After that, click on Display Record List for the newly added domain (the little icon that looks like a miniature version of:
. _____
. _____
. _____
. _____
)
Click Add A Record
Put in IP Address.
Click on Add MX Record
Put in URL for mail server
Click on Add A Record
Put in URL for mail server and IP address of mail server.

Ta-da!

I run my email, DNS, and game server on same box and hosting on a shared hosting package (want to migrate it once I get around to figuring out phpsuexec and all that stuff).

My method is a little different though it consists of going:

cd /var/named/chroot/var/named/zones
cp somesite.com newzone.com
vim newzone.com
*edit appropriately*
:w
:q
service named restart

I'm either a geek, or I'm old fashioned. I plan to code a full blown control panel system though.

Thanks for that. I'm a bit of a DNS newbie, although, I've been coding/running servers for years. I've been playing around with named on a server that won't affect much, but I wanted the crutch of the control panel. Good to know where to find stuff to back up my DNS zones, though!
