Obtain IP from DHCP sever but set DNS servers statically on Debian
If you are sure you are using dhclient
. You can:
1. Change dhclient
setting (recommendded)
Edit the file /etc/dhcp/dhclient.conf
, search for domain-name-servers,
and delete it from the line:
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, domain-search, host-name,
dhcp6.name-servers, dhcp6.domain-search, dhcp6.fqdn, dhcp6.sntp-servers,
netbios-name-servers, netbios-scope, interface-mtu,
rfc3442-classless-static-routes, ntp-servers;
2. Prevent /etc/resolv.conf
from being overwritten
Running the following command as root
or using sudo
so that the file won't get overwritten again:
chattr +i /etc/resolv.conf
It's more or less a duplicated question to Can not set static DNS on debian. But I can't comment so I add this answer.
You can add:
supersede domain-name-servers 127.0.0.1;
to /etc/dhcp/dhclient.conf
