I'm new do Fedora and when ever I install the operating systems I am never able to ssh. Whenever I do something like ssh [email]git@github.com[/email] , I get this error Could not resolve hostname github.com: Name or service not known. I'm able to do 'host github.com' and do 'ping github.com' Both respond as you would expect with the ip.

Can you please post the output of ssh -v and the full command you are trying to try? –  Pratik Amin May 21 '11 at 2:04

can you show us the output of iptables -L? pretty weird if you can ping the hosts (and it responds) but you can't access it.. –  boris quiroz May 21 '11 at 4:52
    
Also, can you please post the line from /etc/nsswitch.conf that starts with hosts, plus the current content of /etc/hosts –  wolfgangsz May 21 '11 at 10:49

Your ssh may try to resolve IP6 and time out doing this. If you are not using IP6 try disabling IP6 in /etc/ssh/ssh_config by changing AddressFamily from 'any' to 'inet'.
