  • Debian Ubuntu Mint Howto Create Bridge (br0)


    Having a network bridge allows you to bridge traffic under multiple devices so they can talk natively without using any special routing, iptables/firewall or other trickery. To create your bridge you need the bridge-utils package for brctl and if you want to do things like bridge VMs that run on a tap device you will need the uml-utilities which provides "tunctl".

    CPanel says you can access 98% of the functions through CLI which experienced Unix/Linux admins prefer for simplicity and for scripting.  I've never found CPanel easy to use from the admin panel, it seems everything is hard to find and a simple task becomes a series of hunts. So for people like me here's the list: http://cpanel.net/system-administrators/command-line-scrip........

  • How to wipe/erase hard drives clean so data cannot be recovered for privacy reasons


    This is something many people and especially businesses worry about, or at least they should. Before throwing away a hard drive, returning a hard drive, or especially Warrantying/RMAing it, you should wipe the drive. Linux provides the "shred" and "dd" utlities which work quite well. It seems even a single pass is good enough but by default shred will do 3 passes. Here's an example of using shred in Linux (I use a custom made distribution from........

    You need to jailbreak your phone and inside Cydia you'll find "PushMod" which will allow you to set your mail check time to 1 minute instead of 15-minutes. This is a great mod and has saved me a lot of stress and frustration, the lack of Blackberry style "free push service" makes iPhone less attractive, but this solves that. Apple needs to make mobileme free and have a Blackberry style chat network to compete, I'm not willing to pay for something Blackberry........

    I've had an old Blackberry for a few years and I was ready to spend some serious cash on a nice Nokia.

Then Iheard about the N97 and what a revolution it was supposed to be and it was even compared to iPhone. To........
