Hi guys. I insalled perfect ubuntu server 12.04 LTS (http://www.howtoforge.com/perfect-server-ubuntu-12.04-lts-nginx-bind-dovecot-ispconfig-3) Everything went "perfect" until last last instruction which is Afterwards you can access ISPConfig 3 under http(s)://server1.example.com:8080/ or http(s)://192.168.0.100:8080/ ( http or https depends on what you chose during installation). Log in with the username admin and the password admin (you should change the default password after your first login): I can only login from my IP or internal IP (192.168.2.140) but not from server1.mydomain.info. I logged to ISP by IP but I didn't do anything for now. I want to solve "login by domain" problem first. So the facts are: I have hosted mydomain.info at hosting company and page is working mydomain.info is registered at gogdaddy and primary DNS is ns1.hostcompany.com secondary DNS is ns2.hostcompany.com I want to have my web page on my new server just for backup in case host company server is down. I have 1 IP. So I assume 1. primary DNS for mydomain.info should stay the same but the secondary DNS should be changed from ns2.hostcompany.com to server1.mydomain.info (server1.mydomain.info is hostname of my server) 2. name server server1.mydomain should be registered at godday Since 2 name server must be registered can I just add server2.mydomain.info and enter the same IP because I have only 1 external IP. Does registrars (in this case godaddy) require any records to be added prior registering name server. Is it possible to register name server at diferent registrar? Is it ok that server si subdomain of web page or it is better to have one domain just for server (and not also for web page) In short what steps need to be taken in order web page to work (not just web server itself to work). I think this will be very usefulf for all begginers to find everthing on one place. If this steps are already wiritten on some other post I will be greatfull for link. Thank you very much!
