It's *DEFINITELY* not! Read the errors!

ping yahoo.com
ping: unknown host yahoo.com


squid service is running
but i can not ping yahoo or any other domain
yesterday all the thins was working today i restart then route is automatically remove and dns entries also from resolve.conf then i put this command chattr +i /etc/resolv.conf after that dns entries is there after reboot but host not resolving

so what happened to the previous page of comments? All irrelevant now?

what are your dns settings? can you ping the dns server IP? Can you hit a web page by IP address?

yes previous all irrelevant bcoz i installed fresh machine it is SElinux and iptables problem which solved and all are working ping nslookup browsing but still dont know about removing config in resolv.conf if i put chattr -i and route also remove on reboot

you re-installed for that??? Blimey!

I presume you are using DHCP for the server? Don't do that. Stop the NetworkManager service and configure the network config statically. It's a server. Treat it as such. You can use a reservation on your DHCP server if need be, but even then, make it give you the right details in the first place.
