what this happens ?

Answer 1

the domain linux.sys65dns.com isn't valid. if this if from a mirrorlist, try a yum clean all and try it again.

Answer 2

Troubleshooting steps (assuming this is your locally hosted repo):

1. Rומ yum clean all and try to install ntp again. For testing purposeד try to install a different package.
2. If the above fails, try to ping your server: ping linux02.sys65dns.com
3. If the above, try to open this in a web browser to check if port 80 is working fine or you can telnet as well.
4. If not, check the apache service on your server and if port 80 is open. You can also check the ports.conf to see if apache is configured to work on port 80 or a different port.
