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
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.
