    Author: Falko TimmeTags: , Comments: 2

    Creating Encrypted FTP Backups With duplicity And ftplicity On Debian Etch When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and ftplicity to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. ftplicity is a duplicity wrapper script (provided by the German computer magazine c't) that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

    Set Up Postfix For Relaying Emails Through Another Mailserver This short guide shows how you can set up Postfix to relay emails through another mailserver. This can be useful if you run a Postfix mailserver in your local network and have a dynamic IP address because most dynamic IP addresses are blacklisted today. By relaying your emails through another mailserver that is hosted on a static IP address in a data center (e.g. your ISP's mailserver) you can prevent your emails from being categorized as spam.

  • 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)

    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.
