COPY PASTE : DNS SERVER USING UBUNTU 9.10

20 Januari 2011

Run
aptitude install bind9
For security reasons we want to run BIND chrooted so we have to do the following steps:
/etc/init.d/bind9 stop
Edit the file /etc/default/bind9 so that the daemon will run as the unprivileged user bind, chrooted to /var/lib/named. Modify the line: OPTIONS="-u bind" so that it reads OPTIONS="-u bind -t /var/lib/named":
vi /etc/default/bind9
# run resolvconf?
RESOLVCONF=yes

# startup options for the server
OPTIONS="-u bind -t /var/lib/named"
Create the necessary directories under /var/lib:
mkdir -p /var/lib/named/etc
mkdir /var/lib/named/dev
mkdir -p /var/lib/named/var/cache/bind
mkdir -p /var/lib/named/var/run/bind/run
Then move the config directory from /etc to /var/lib/named/etc:
mv /etc/bind /var/lib/named/etc
Create a symlink to the new config directory from the old location (to avoid problems when bind gets updated in the future):
ln -s /var/lib/named/etc/bind /etc/bind
Make null and random devices, and fix permissions of the directories:
mknod /var/lib/named/dev/null c 1 3
mknod /var/lib/named/dev/random c 1 8
chmod 666 /var/lib/named/dev/null /var/lib/named/dev/random
chown -R bind:bind /var/lib/named/var/*
chown -R bind:bind /var/lib/named/etc/bind

We need to create the file /etc/rsyslog.d/bind-chroot.conf...
vi /etc/rsyslog.d/bind-chroot.conf
... and add the following line so that we can still get important messages logged to the system logs:
$AddUnixListenSocket /var/lib/named/dev/log
Restart the logging daemon:
/etc/init.d/rsyslog restart
Start up BIND, and check /var/log/syslog for errors:
/etc/init.d/bind9 start
