you can also answer this on google for $80 http://answers.google.com/answers/threadview?id=457267 For some I cannot connect to ftp, pop, smtp, mysql -- all ports other than 80, ssl and ssh, from outside the network. I can connect only to "localhost " but cannot from outside. Here is an example trying to connect to ftp from my home pc : Same happens when I connect to ftp, mysql, anything other than ports 80, ssl, ssh. I can connect to mysql only when I set it to operate on port 80 (and stop httpd of course) Moreover, the root server does not connect to other servers. I tried downloading from other servers, and using curl -- all failed. Even my php scripts cannot conenct to anywhere; or when I try to use apache as a proxy server, connecting to another server -- I get connection falures. I can connect to localhost only - wget localhost works fine.. Server has Fedora Core 2 Linux Plesk 7.5 Reloaded. The iptables are empty, plesk firewall setting allow everything.. Still all ports bloked. I used nmap to scan ports on the server - www, ssh, plesk - are the only open ports!! I just got the server from 1&1. Please advise how I can fix it. Thanks!
