| + | ==== Jailkit ==== | ||
| + | ---- | ||
| + | Jailkit is needed only if you want to chroot SSH users. It must be installed before ISPConfig - it cannot be installed afterwards! | ||
| + | |||
| + | <code> | ||
| + | > apt-get install build-essential autoconf automake1.9 libtool flex bison debhelper binutils-gold | ||
| + | > cd /tmp | ||
| + | > wget http://olivier.sessink.nl/jailkit/jailkit-2.15.tar.gz | ||
| + | > tar xvfz jailkit-2.15.tar.gz | ||
| + | > cd jailkit-2.15 | ||
| + | > ./debian/rules binary | ||
| + | > cd .. | ||
| + | > dpkg -i jailkit_2.15-1_*.deb | ||
| + | > rm -rf jailkit-2.15* | ||
| + | </code> | ||
| + | |||
| + | ==== fail2ban ==== | ||
| + | ---- | ||
| + | <code> | ||
| + | > apt-get install fail2ban | ||
| + | </code> | ||
| + | |||
| + | To have fail2ban monitor PureFTPd and Dovecot, create (or edit) the file **/etc/fail2ban/jail.local**: | ||
| + | <code> | ||
| + | > nano /etc/fail2ban/jail.local | ||
| + | |||
| + | [pureftpd] | ||
| + | enabled = true | ||
| + | port = ftp | ||
| + | filter = pureftpd | ||
| + | logpath = /var/log/syslog | ||
| + | maxretry = 3 | ||
| + | |||
| + | [dovecot-pop3imap] | ||
| + | enabled = true | ||
| + | filter = dovecot-pop3imap | ||
| + | action = iptables-multiport[name=dovecot-pop3imap, port="pop3,pop3s,imap,imaps", protocol=tcp] | ||
| + | logpath = /var/log/mail.log | ||
| + | maxretry = 5 | ||
| + | |||
| + | [sasl] | ||
| + | enabled = true | ||
| + | port = smtp | ||
| + | filter = sasl | ||
| + | logpath = /var/log/mail.log | ||
| + | maxretry = 3 | ||
| + | </code> | ||
| + | |||
| + | Create two more files: | ||
| + | <code> | ||
| + | > nano /etc/fail2ban/filter.d/pureftpd.conf | ||
| + | |||
| + | [Definition] | ||
| + | failregex = .*pure-ftpd: \(.*@<HOST>\) \[WARNING\] Authentication failed for user.* | ||
| + | ignoreregex = | ||
| + | |||
| + | > nano /etc/fail2ban/filter.d/dovecot-pop3imap.conf | ||
| + | |||
| + | [Definition] | ||
| + | failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed|Aborted login \(\d+ authentication attempts).*rip=(?P<host>\S*),.* | ||
| + | ignoreregex = | ||
| + | </code> | ||
| + | |||
| + | Finally, restart fail2ban: | ||
| + | <code> | ||
| + | > /etc/init.d/fail2ban restart | ||
| + | </code> | ||
| + | |||
| + | ==== SquirrelMail ==== | ||
| + | ---- | ||
| + | This has not been done here, for reference, see [[http://www.howtoforge.com/perfect-server-debian-wheezy-nginx-bind-dovecot-ispconfig-3-p5|this page of The Perfect Server - Debian Wheezy site]]... | ||
