If the system is going to be connected to the Internet, it will need
some means of Domain Name Service (DNS) name resolution to resolve
Internet domain names to IP addresses, and vice versa. This is best
achieved by placing the IP address of the DNS server, available from
the ISP or network administrator, into /etc/resolv.conf. If at least one of your network
interfaces is going to be configured by DHCP then you may not need to
create this file. By default DHCPCD will overwrite this file when it
gets a new lease from the DHCP server. If you wish to manually
configure your network interfaces or manually set your DNS using DHCP
then create the file by running the following:
cat > /etc/resolv.conf << "EOF"
# Begin /etc/resolv.conf
domain [Your Domain Name]
nameserver [IP address of your primary nameserver]
nameserver [IP address of your secondary nameserver]
# End /etc/resolv.conf
EOF
The domain statement can be
omitted or replaced with a search statement. See the man page
for resolv.conf for more details.
Replace [IP address of the
nameserver] with the IP address of the DNS most
appropriate for the setup. There will often be more than one entry
(requirements demand secondary servers for fallback capability). If
you only need or want one DNS server, remove the second nameserver line from the file. The IP
address may also be a router on the local network.
