The Perfect Server - Ubuntu 11.10 With Nginx [ISPConfig 3] - Page 5
16 Install PureFTPd And Quota
PureFTPd and quota can be installed with the following command:
apt-get install pure-ftpd-common pure-ftpd-mysql quota quotatool
Edit the file /etc/default/pure-ftpd-common...
vi /etc/default/pure-ftpd-common
... and make sure that the start mode is set to standalone and set VIRTUALCHROOT=true:
[...] STANDALONE_OR_INETD=standalone [...] VIRTUALCHROOT=true [...] |
Now we configure PureFTPd to allow FTP and TLS sessions. FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure.
If you want to allow FTP and TLS sessions, run
echo 1 > /etc/pure-ftpd/conf/TLS
In order to use TLS, we must create an SSL certificate. I create it in /etc/ssl/private/, therefore I create that directory first:
mkdir -p /etc/ssl/private/
Afterwards, we can generate the SSL certificate as follows:
openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout /etc/ssl/private/pure-ftpd.pem -out /etc/ssl/private/pure-ftpd.pem
Country Name (2 letter code) [AU]: <-- Enter your Country Name (e.g., "DE").
State or Province Name (full name) [Some-State]: <-- Enter your State or Province Name.
Locality Name (eg, city) []: <-- Enter your City.
Organization Name (eg, company) [Internet Widgits Pty Ltd]: <-- Enter your Organization Name (e.g., the name of your company).
Organizational Unit Name (eg, section) []: <-- Enter your Organizational Unit Name (e.g. "IT Department").
Common Name (eg, YOUR name) []: <-- Enter the Fully Qualified Domain Name of the system (e.g. "server1.example.com").
Email Address []: <-- Enter your Email Address.
Change the permissions of the SSL certificate:
chmod 600 /etc/ssl/private/pure-ftpd.pem
Then restart PureFTPd:
/etc/init.d/pure-ftpd-mysql restart
Edit /etc/fstab. Mine looks like this (I added ,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 to the partition with the mount point /):
vi /etc/fstab
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 /dev/mapper/server1-root / ext4 errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0 1 # /boot was on /dev/sda1 during installation UUID=6fbce377-c3d6-4eb3-8299-88797d4ad18d /boot ext2 defaults 0 2 /dev/mapper/server1-swap_1 none swap sw 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0 |
To enable quota, run these commands:
mount -o remount /
quotacheck -avugm
quotaon -avug
17 Install BIND DNS Server
BIND can be installed as follows:
apt-get install bind9 dnsutils
18 Install Vlogger, Webalizer, And AWstats
Vlogger, webalizer, and AWstats can be installed as follows:
apt-get install vlogger webalizer awstats geoip-database
Open /etc/cron.d/awstats afterwards...
vi /etc/cron.d/awstats
... and comment out both cron jobs in that file:
#*/10 * * * * www-data [ -x /usr/share/awstats/tools/update.sh ] && /usr/share/awstats/tools/update.sh # Generate static reports: #10 03 * * * www-data [ -x /usr/share/awstats/tools/buildstatic.sh ] && /usr/share/awstats/tools/buildstatic.sh |
19 Install Jailkit
Jailkit is needed only if you want to chroot SSH users. It can be installed as follows (important: Jailkit must be installed before ISPConfig - it cannot be installed afterwards!):
apt-get install build-essential autoconf automake1.9 libtool flex bison debhelper binutils-gold
cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.14.tar.gz
tar xvfz jailkit-2.14.tar.gz
cd jailkit-2.14
./debian/rules binary
You can now install the Jailkit .deb package as follows:
cd ..
dpkg -i jailkit_2.14-1_*.deb
rm -rf jailkit-2.14*
20 Install fail2ban
This is optional but recommended, because the ISPConfig monitor tries to show the fail2ban log:
apt-get install fail2ban
To make fail2ban monitor PureFTPd, SASL, and Courier, create the file /etc/fail2ban/jail.local:
vi /etc/fail2ban/jail.local
[pureftpd] enabled = true port = ftp filter = pureftpd logpath = /var/log/syslog maxretry = 3 [sasl] enabled = true port = smtp filter = sasl logpath = /var/log/mail.log maxretry = 5 [courierpop3] enabled = true port = pop3 filter = courierpop3 logpath = /var/log/mail.log maxretry = 5 [courierpop3s] enabled = true port = pop3s filter = courierpop3s logpath = /var/log/mail.log maxretry = 5 [courierimap] enabled = true port = imap2 filter = courierimap logpath = /var/log/mail.log maxretry = 5 [courierimaps] enabled = true port = imaps filter = courierimaps logpath = /var/log/mail.log maxretry = 5 |
Then create the following five filter files:
vi /etc/fail2ban/filter.d/pureftpd.conf
[Definition] failregex = .*pure-ftpd: \(.*@<HOST>\) \[WARNING\] Authentication failed for user.* ignoreregex = |
vi /etc/fail2ban/filter.d/courierpop3.conf

#
failregex = pop3d: LOGIN FAILED.*ip=\[.*:<HOST>\]
# Option: ignoreregex

ignoreregex =

Restart fail2ban afterwards:
/etc/init.d/fail2ban restart
