Are you using SSH in the best way possible? Have you configured it to be as limited and secure as possible? The goal of this document is to kick in the new year with some best practices for SSH: why you should use them, how to set them up, and how to verify that they are in place.
All of the examples below assume that you are using EnGarde Secure Linux but any modern Linux distribution will do just fine since, as far as I know, everybody ships OpenSSH.
There are numerous benefits to using the latest version of the SSH protocol, version 2, over it’s older counterpart, version 1 and I’m not going into a lot of details on those benefits here – if you’re interested, see the URL in the reference below or Google around. That being said if you don’t have an explicit reason to use the older version 1, you should always be using version 2.
This howto outlines the process by which one can set up the Subversion version control system, and have it work in tandem with Trac, the project manager for software development projects, on a server running Ubuntu (or possibly Debian). It is brought to you by Openject Consulting.
For detailed information on this, including alternate setups, have a look at Version Control with Subversion.

This tutorial shows how to set up a CentOS 4.6 based server that offers all services needed by ISPs and web hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of CentOS 4.6, but should apply to the 64-bit version with very little modifications as well.
I will use the following software:
In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).
I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!
Creating an AS400 terminal with an Old PC and Ubuntu
This how to uses Ubuntu 7.10 Server install. I am sure that this could be done with a much smaller install base, rather than server – I might have used the Alternative CD, or maybe even some other distribution like DSL, or Puppy Linux (if you needed GUI [graphical user interface] ). But for proof of concept this worked fine. I used an Old Dell GX100 Optiplex with 256 MB of RAM (I don’t think I need any more that 128 [maybe even 64MB], but this is what was in the box when I pulled it out of the pile). It has a small form factor, and runs pretty quiet. My steps are geared toward English & US, so you may want to change those if your using something else =).
Build A HylaFax Server With AvantFax Frontend Using Debian Etch
Install Debian. I used the basic barebones install option. I did
some things that were done because of preference, and not necessary. I
have marked them approriately. I encourage contributions from anyone
who would like to add or correct something in this HowTo to contact me
so I can fix it. I have installed this setup twice following these
instructions and used Avantfax 2.3.0. Thanks to all the resources who
helped me figure this out. Especially Razametal, who submitted a
fantastic Spanish language walkthrough on ecualug.org.
Writing Snort Rules On EnGarde
There are already tons of written Snort rules, but there just might
be a time where you need to write one yourself. You can think of
writing Snort rules as writing a program. They can include variables,
keywords and functions. Why do we need to write rules? The reason is,
without rules Snort will never detect someone trying to hack your
machine. This HOWTO will give you confidence to write your own rules.
How To Masquerade On Linux (Internet Connection Sharing)
It’s very simple to masquerade (internet connection sharing in
Windows language ) on Linux with a few lines of iptables and ip_forward
commands.
Network Management And Monitoring With Hyperic HQ On Fedora 8
This document describes how to set up Hyperic HQ on Fedora 8. The
resulting system provides an awesome, web-based “System
ManagementSoftware”. It’s the next stage of classical monitoring and
able to manage all kinds of operating systems, web servers, application
servers and database servers.
Sample Configuration of DRBD On CentOS 4.5
DRBD is an abbreviation of Distributed Replicated Block Device.
DRBD is a block device which is designed to build high-availability
clusters. This is done by mirroring a whole block device via (a
dedicated) network. You could see it as a network RAID1.
