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]firstname.lastname@example.org[/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.
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'.
