I have installed Webmin 1.550 on Ubuntu 10.4 LTS and then installed Virtualmin on top of that. I have not done much to set up Webmin (including DNS), and have proceeded to the Post Installation Wizard for Virtualmin. I get through the first few frames and encounter this when it checks for resolvability:
Primary nameserver cannot be resolved from the rest of the Internet : epsilon.scubaboard.com has address 18.104.22.168 Host epsilon.scubaboard.com not found: 3(NXDOMAIN)
Pinging epsilon.scubaboard.com brings back 22.214.171.124 is is one of several IPs I have bound to the server through /etc/network/interfaces.
As background, this is my 11th server in my dedicated rack at Atlantic.net. It is the first server I have ever configured and its my first time using Webmin/Virtualmin. I have grown to loathe Plesk and cPanel just doesn't give me the warm fuzzies. I have two DNS servers, sblb1.scubaboard.com and sblb2.scubaboard.com that do nothing but provide dns for scubaboard.com. ScubaBoard is the largest forum for Scuba Divers and is my main source of income. Epsilon is to be used as a LAMP server and will ultimately replace sb400.scubaboard.com, a LAMP server using Plesk.
