Hands-On Exercise

Setup a caching name server on your system:

sudo bash

apt-get install bind9

vim /etc/bind/named.conf.options

# change the forwarders section to the following:

forwarders {

134.197.6.1;

134.197.5.1;

};

# If you installed off-campus you’ll need to set the

# forwarders to match your current DNS servers

# If your resolv.conf looks like this:

# cat /etc/resolv.conf

nameserver 192.168.1.254

# then set forwarders to:

forwarders {

192.168.1.254;

};

# replace your nameserver lines with the following (localhost):

vim /etc/resolv.conf

nameserver 127.0.0.1

# make sure DHCP does not overwrite your changes

vim /etc/dhcp/dhclient.conf

prepend domain-name-servers 127.0.0.1;

/etc/init.d/bind9 restart

# make sure DNS still works
