Install Quota

apt-get install quota quotatool

- To the prompt: Send Daily reminders to users over quota answer No

Edit /etc/fstab to look like this (I added ,usrquota,grpquota to the partition with the mount point / -- This assumes that everything needing quota support is under /):

joe /etc/fstab 

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda1       /               ext3    defaults,errors=remount-ro,usrquota,grpquota 0       1
/dev/sda5       none            swap    sw              0       0
/dev/hdc        /media/cdrom0   iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0

Then run:

touch /quota.user /quota.group
chmod 600 /quota.*
mount -o remount /
quotacheck -avugm


Install DNS-Server

apt-get 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: OPTS="-u bind" so that it reads OPTS="-u bind -t /var/lib/named":

joe /etc/default/bind9 

OPTS="-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 is upgraded 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 modify the startup script /etc/init.d/sysklogd of sysklogd so that we can still get important messages logged to the system logs. Modify the line: SYSLOGD="" so that it reads: SYSLOGD="-a /var/lib/named/dev/log"

joe /etc/init.d/sysklogd 

#! /bin/sh
# /etc/init.d/sysklogd: start the system log daemon.

PATH=/bin:/usr/bin:/sbin:/usr/sbin

pidfile=/var/run/syslogd.pid
binpath=/sbin/syslogd

test -x $binpath || exit 0

# Options for start/restart the daemons
#   For remote UDP logging use SYSLOGD="-r"
#
SYSLOGD="-a /var/lib/named/dev/log"

create_xconsole()
{
    if [ ! -e /dev/xconsole ]; then
        mknod -m 640 /dev/xconsole p
    else
        chmod 0640 /dev/xconsole
    fi
    chown root:adm /dev/xconsole
}

running()
{
    # No pidfile, probably no daemon present
    #
    if [ ! -f $pidfile ]
    then
        return 1
    fi

    pid=`cat $pidfile`

    # No pid, probably no daemon present
    #
    if [ -z "$pid" ]
    then
        return 1
    fi

    if [ ! -d /proc/$pid ]
    then
        return 1
    fi

    cmd=`cat /proc/$pid/cmdline | tr "\000" "\n"|head -n 1`

    # No syslogd?
    #
    if [ "$cmd" != "$binpath" ]
    then
        return 1
    fi

    return 0
}
 
case "$1" in
  start)
    echo -n "Starting system log daemon: syslogd"
    create_xconsole
    start-stop-daemon --start --quiet --exec $binpath -- $SYSLOGD
    echo "."
    ;;
  stop)
    echo -n "Stopping system log daemon: syslogd"
    start-stop-daemon --stop --quiet --exec $binpath --pidfile $pidfile
    echo "."
    ;;
  reload|force-reload)
    echo -n "Reloading system log daemon: syslogd"
    start-stop-daemon --stop --quiet --signal 1 --exec $binpath --pidfile $pidfile
    echo "."
    ;;
  restart)
    echo -n "Restarting system log daemon: syslogd"
    start-stop-daemon --stop --quiet --exec $binpath --pidfile $pidfile
    sleep 1
    start-stop-daemon --start --quiet --exec $binpath -- $SYSLOGD
    echo "."
    ;;
  reload-or-restart)
    if running
    then
        echo -n "Reloading system log daemon: syslogd"
        start-stop-daemon --stop --quiet --signal 1 --exec $binpath --pidfile $pidfile
    else
        echo -n "Restarting system log daemon: syslogd"
        start-stop-daemon --start --quiet --exec $binpath -- $SYSLOGD
    fi
    echo "."
    ;;
  *)  
    echo "Usage: /etc/init.d/sysklogd {start|stop|reload|restart|force-reload|reload-or-restart}"
    exit 1
esac

exit 0

Restart the logging daemon:

/etc/init.d/sysklogd restart

Start up BIND, and check /var/log/syslog for any errors:

/etc/init.d/bind9 start
less /var/log/syslog

up
