  • HowTo: Install And Configure FWKNOP (Using EnGarde Linux)

    Author: secureguardianTags: Comments: 0

    HowTo: Install And Configure FWKNOP (Using EnGarde Linux) Secret knocks have been used for purposes as simple and childish as identifying friend or foe during a schoolyard fort war. Fraternities teach these knocks as a rite of passage into their society, and in our security world we can implement this layer of security to lock down an SSH server. The FireWall KNock Operator (fwknop) is an excellent port knocking implementation that combines encrypted port knocking with passive OS finger-printing. This makes it possible to define specifically which Linux systems are allowed access to your SSH server. fwknop combines its functionality with iptables rules and log messages to grant or deny access to the SSH daemon.

    Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1) This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.
