Hello there ! I was so proud with my own DNS working well for 2 days but recently when i restarted the computer, the bind9 didn't restart ! When i make Code: /etc/init.d/bind9 restart it shows this : Code: * Stopping domain name service... rndc: connect failed: connection refused ...done. * Starting domain name service... ...done. One clue is that i changed the certificates like in this Falko's explanations : http://www.howtoforge.com/forums/showthread.php?t=2700&page=2&highlight=openssl Does it deals with that or any authorisations settings ? One more thing : i had a dyndns name (burtnet.dyndns.org) that i abandon in those last days and when i connect the ispconfig interface : it doesn't load pages well and still make reference of this dyndns url in spite of having my new domain inside my /home/admispconfig/ispconfig/lib/config.inc.php : Code: $go_info["server"]["server_url"] = "https://petiteboitesansfond.net:81/"; thanks guys !
