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.

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.
