Hi Falko, This time I tried Debian Sarge 3.1 instructions on my Kanotix RC-11 version. Everything went fine not even a single error. Also I omitted Courier section. After installing ISPConfig and logged in as admin. I selected the Services section and found the following:- Web-Server: Online FTP-Server: Online SMTP-Server: Online POP3-Server: Offline BIND-Server: Online mySQL-Server: Online and my nmap on localhost shows the following, i could not see any 110 port in it. Could you please tell me what might have gone wrong and how can I now get the Pop3 service running, which in the above ISPConfig would change from Offline to Online. Please see my nmap output below:- Code: [email protected]:~# nmap localhost Starting nmap 3.93 ( http://www.insecure.org/nmap/ ) at 2005-10-22 20:45 BST Interesting ports on localhost.localdomain (127.0.0.1): (The 1659 ports scanned but not shown below are in state: closed) PORT STATE SERVICE 21/tcp open ftp 25/tcp open smtp 53/tcp open domain 80/tcp open http 81/tcp open hosts2-ns 443/tcp open https 631/tcp open ipp 953/tcp open rndc 3306/tcp open mysql Nmap finished: 1 IP address (1 host up) scanned in 0.218 seconds [email protected]:~# Please help me to get this one right.
