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

test -x $binpath || 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
