Linux: HowTo: Emergency Reboot a Remote Machine

10/30/2007  
Relevance: 7.41
Sometimes the machine you're working on has a little oops. Maybe the reboot command has hung and the system will not shutdown or a kernel panic has occurred and although you still have shell access, there is little more you can do with the machine. The solution is simple: you need to hard reboot the machine. But you're in Phoenix and the machine is in L.A. Like any good system administrator, you have the machine hooked up to an IP-KVM (or serial over IP, if the machine is headless), but the magic SysRq keys won't send properly. So what's a sysadmin to do?

P2V: How To Make a Physical Linux Box Into a Virtual Machine

08/21/2007  
Relevance: 6.03
Over the last four days, I've been exploring how to convert physical Linux boxes into virtual machines. VMWare has a tool for doing P2V conversions, as they're called, but as far as I can tell it only works for Windows physical machines and for converting various flavors of virtual machines into others. I could have just rebuilt the whole machine from scratch on a new virtual machine, but that takes a lot of time and the old build isn't that out of date (one year) and works fine. So, I set out to discover how to transfer a physical machine to a virtual machine.

A virtual appliance primer

06/17/2008  
Relevance: 6.01
Virtual machines are virtually taking over the world. By itself a virtual machine is just a container that describes various resources such as memory, disk space, processor, and network card, and allocates them from a physical machine. As with a physical machine, it's the software bits (the operating system and applications) that make a virtual machine usable. When you mix a virtual machine with real software you get a virtual appliance. Some complete Linux distributions as well as specialized apps are available as virtual appliances. Thanks to the ease in packaging one, there's no shortage of virtual appliances around, if you know where to look.

Hackers attack Large Hadron Collider

Relevance: 5.70
The hacking attempt started around the time that the giant machine was about to circulate its first particles, under the spotlight of the world's media. On Wednesday afternoon, as the world held its breath as the machine sparked up, CMS team members were scouring computers at the machine for half a dozen files uploaded by the hackers on September 9 and 10."We think that someone from Fermilab's Tevatron (the competing atom smasher in America) had their access details compromised," said one of the scientists working on the machine."What happened wasn't a big deal, just goes to show people are out there always on the prowl."

Installing Xen On CentOS 5.2 (i386)

11/09/2008  
Relevance: 5.44
This tutorial provides step-by-step instructions on how to install Xen on a CentOS 5.2 system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called virtual machines or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

Apple's"Time Machine" Now For Linux...

11/10/2007  
Relevance: 5.17
Apple's Time Machine is a great feature in their OS, and Linux has almost all of the required technology already built in to recreate it. This is a simple GUI to make it easy to use."Apple's 'Time Machine' is cool, but I use Linux, not MacOSX. So here is a Linux implementation (built off of rsync, of course). No fancy OpenGL, but quite functional none-the-less."

NorhTec MicroClient Jr. Review

07/02/2007  
Relevance: 5.00
Weighing in at 505 grams (just over a pound) and selling for around 100$(USD) the MicroClient Jr. is an inexpensive SFF machine. PCBurn takes a look to see what it's got internally and how well it can run Slax, DSL, or as an LTSP thin client. Will it be a good fit as your next always-on web browser or POS machine?

Interrogating a Linux Machine

11/26/2008  
Relevance: 4.93
The other day, a client called upon me to perform a hardware and software inventory on all of the computers on his network. There weren't that many machines to inventory, but we needed to gather quite a bit of information about each one. The client was a Microsoft shop and so I had to deal with about an even mix of Windows XP and Vista with a few Windows 95, 98, and ME machines thrown in for good measure. So off I went, with an Excel spreadsheet in hand. I visited each machine in person. For each machine, I wanted the network configuration, the workgroup configuration, and the hardware configuration.

Upgrade from 32-bit to 64-bit Fedora Linux without a system reinstall

01/12/2008  
Relevance: 4.90
One great thing about Linux is that you can transplant a hard disk from a machine that runs a 32-bit AMD XP processor into a new 64-bit Intel Core 2 machine, and the Linux installation will continue to work. However, if you do this, you'll be running a 32-bit kernel, a C library, and a complete system install on a processor that could happily run 64-bit code. You'll waste even more resources if your new machine has 4GB or more of system memory, and you'll be forced to either not use some of it or run a 32-bit Physical Address Extension (PAE) kernel. Cross-grading to the 64-bit variant of your Linux distribution can help you use your resources more wisely.
