  • PeteNetLive – KB0000741 – HP and Cisco – VLANs and Trunks Confusion! – When I first started in IT, I went and did my Cisco CCNA. So I learned that to connect Cisco switches and pass VLAN traffic between them, I needed to create a 'Trunk' to pass the VLAN traffic. Fast forward a few years, and I now work for an HP reseller. Very early on I came to realise that what HP called a 'trunk' was very different from what I had been taught. Below is an article I did a while ago about setting up HP Trunks.
  • OpenNOP – Open Network Optimization Platform – OpenNOP is an open source Linux based network accelerator. It's designed to optimise network traffic over point-to-point, partially-meshed and full-meshed IP networks.
    The goal of OpenNOP is to increase network performance over low speed network connections such as ISDN, DSL, DS1, frame-relay, VPN and other network circuits. To accomplish this we can use a variety of techniques such as compression, deduplication, caching and protocol spoofing.
    The objectives for OpenNOP are:
    Produce a low cost solution to increase network performance, improve the end user experience and deliver this in a easy to use appliance image.
    Provide a single solution for networks on terrestrial, cellular and satellite systems.
    Facilitate an open framework that can be extended by 3rd party modules to improve specific network traffic.
  • Deon’s World – Understanding and using htop to monitor system resources – Every so often there will be something that slows a system down. There are a few tools that can help to identify which process is the cause of this slow down. One such tool is htop. Htop is an interactive and real time process monitoring application for Linux which will show you your usage per cpu/core, as well as a meaningful text graph of your memory and swap usage.

  • Native Cisco VPN on Mac OS X – With Group Password Decoder! – The proprietary CiscoVPN Mac client is somewhat buggy. It is possible to use the IPSec VPN software included with Mac OS X instead. This tutorial shows you how to migrate from CiscoVPN to the native OS X IPSec VPN by decrypting passwords saved in CiscoVPN PCF files.
  • How to Run Internet Explorer 7, 8 and 9 in Linux with or without Wine – How to Run Internet Explorer 7, 8 and 9 in Linux with or without Wine
    Microsoft have a wonderfully long history of badly designed software that they're proudly continuing to this day with the abomination of IE 9 and the ghastly sham that is Windows 7. It's a tribute to the skills of the many hard-working marketing heads over at Redmond that despite the poor quality and the easy availability of superior cost-free alternatives, people the world over keep coming back to Microsoft like hookers on crack.
  • Welcome to perlmeme.org – perlmeme.org is a collection of Frequently Asked Questions, "How To" documents, and tutorials about the very cool Perl programming language.
    The documents cover a range of expertise levels. Some are suitable for beginners, others assume that you know some Perl already, and others cover advanced topics.
    If you're new to Perl, or even new to programming in general then perlmeme.org is a great place to start. However, there's plenty of in-depth material here as well.
