I got a program JumboLinux DNS from a Person 6 years ago. It worked great untel 2 years ago, at that time I paid $25 down loaded it again but never checked the disk, come find out now that had no bootup on it, so after a week of telling him, He finally put a good copy on line. I downloaded it and it works. After installing it I found three problems with the programs are very different. The second is i need to know how to change the root name from localhost.localdomain to The third problem is to start adding the domain name. to the DNS records. Can someone help?
