Hi All,

We have some domains. I put all those domain in /etc/resolv.conf in Search list for host-name lookup but whenever I am restarting the network service or machine the resolv.conf gets update and it gets updated with DNS variables/configuration from /etc/sysconfig/network-scripts/ifcfg-em1 file. I tried to configure DNS with system-config-network command but still the same observation/result.

Could you please let me know what is the reason behind getting updated the /etc/resolv.conf file after every reboot or service start.

which distro are you using?

Is NetworkManager runningon the system? If yes then check whether issue reproduces if NetworkManager is turned off.

i don't know about your system, but resolv.conf gets overwritten by dhcp on every boot if you use dhcp.

You can try write-protecting the file.

chattr +i /etc/resolv.conf

Thanks Shridhar, turning off NetworkManager service worked for me.
