New Linux Guide Section
I’ve added a new section call Linux Guide, which believe it or not contain guides on Linux. The first big guide is up now. It’s a guide on using Samba and LDAP as a Windows Domain Controller. Link here.
Ubuntu 8.04 Beta
Ubuntu has just released a beta for the new April release of “Hardy Heron” as it’s called. Lots of new features have been included.
- Linux kernel 2.6.24
- GNOME 2.22
- PolicyKit
- Firefox 3 Beta 4
- Virtualization
- ActiveDirectory integration
- Memory Protection
- Wubi
I think one of my favorites has to be Wubi, what this is an installer for Windows. What it does is allows a user to install/uninstall Ubuntu just like any other application, with no need to have another boot loader or separate partition. For those that prefer KDE to Gnome the Kubuntu beta is also out and can be found here. Kubuntu has is available with either KDE 3.5 or the shiny new KDE 4.
High Performance Enabled SSH
For those who don’t know SSH - Secure SHell - is a secure way of remote administration of a server through the command line. This was first used in Unix servers but has made it’s way to Linux and Windows, thanks to open source software.
There is also a different way to use SSH, to make a secure tunnel between a client and server for transferring files. This is known as SCP. The biggest downfall with SCP is that it relied on SSH which by nature was slower because of the computation of the encryption. Now since machines have been getting more powerful, and bandwidth getting faster this downfall is prominent. So the Advanced Computing Group have made improvement to the core of SSH. These improvements were to the flow control buffers, the main bottleneck of the SSH protocol. The new implementation of HPN-SSH now defines the buffers at run-time, meaning the buffers can be increased as long as the link between the server and client is healthy.
The Advanced Computing Group claims to be able to improve the throughput by as much as 1000% just by increasing the buffer size. The group also made available patches to the popular OpenSSH software. I have yet to try this patches but as far as I can tell this looks to be very promising.

Fedora 8 Released
Fedora 8 was released and some of the biggest improvements were to the audio system. A new daemon dubbed PulseAudio allows much more control over audio streams and the programs producing them. Another big improvement is the inclusion of a little utility called Codeina which allows user to purchase legal codecs for dealing with different media formats. PolicyKit is the new authentication system that aims to make programs that require root access more secure by only allowing certain processes of the program root access.
The full feature list can be found here.
