Want to build a high end desktop computer for a low end price (around $600 or less)?
Note: I don’t include Windows 7 in the default build, as you can just download Ubuntu, Fedora, or OpenSuSE Linux etc. for free. However, I’ve included links for Windows 7 (student and normal) in the Additional options section.
I would like to suggest the following components for people that want a really nice system without breaking the bank.
I just built a new machine that could support running multiple VMware instances, encode FLAC quickly, and surf the web etc. without breaking the bank. I didn’t need or want video gaming support since I use a PS3 for that.
However, I’ll suggest a view options (including gaming cards) that will allow you to alter the basic system we’ll be discussing.
This build is based on AMD/ATI since it really does perform well and saves a good chunk of money, but the parts can be swapped very easily to make it an Intel system that won’t break the bank either.
I’ll expand on why I chose the parts and provide direct links as well. (I use Newegg, but use anyone you like)
Detective Inspector Bruce van der Graaf from the Computer Crime Investigation Unit of the NSW Police says, “”If you are using the internet for a commercial transaction, use a Linux boot up disk – such as Ubuntu or some of the other flavours…It gives you an operating system which is perfectly clean and operates only in the memory of the computer and is a perfectly safe way of doing internet banking,”
Sounds like a good plan to me, but then, I’m sure most of you reading this are already in agreement. It’s just good to see this sort of thing hitting major news sites.
I'm providing the original text file for ease of use Grab it here - ClamAV.on.Fedora
----------------------------------
Background:
This guide will use the ClamAV CLI scanner and the ClamAV-Update script (freshclam).
I wrote this to help all the Home\SOHO users (servers or desktops).
ClamAV has various tools/packages/plugins for email servers etc. but that’s another story.

Obviously, you can change anything you want, but this should get you going.
Have you ever been in a rush or just had a complete brain freeze with your MySQL passwords?
Well…..I have. 
——————————-
Step # 1 : Stop mysql service
SHELL> /etc/init.d/mysql stop
——————————-
Step # 2: Start to MySQL server w/o password:
SHELL> mysqld_safe --skip-grant-tables &
——————————-
Step # 3: Connect to mysql server using mysql client and setup the new root password:
SHELL> mysql -u rootmysql> use mysql; mysql> update user set password=PASSWORD("$PASSWORD") where User='root'; mysql> flush privileges; mysql> quit
——————————-
Step #4: Stop and Restart MySQL Server: (try your new $PASSWORD)
SHELL> /etc/init.d/mysql stop SHELL> /etc/init.d/mysql start SHELL> mysql -u root -p
——————————-
Note: There are other ways to reset the password, but I like this one.
Over the past few years several people on the VMware communities forums have released patches to fix the vmware modules for the next “fresh” release of the Linux Kernel / Distro. I’ve used them in the past with much success, but I generally like waiting for the official VMware support. However, I’m pretty excited about Fedora 11 (just to many new goodies not to play) and I noticed there’s a new updated patch for 2.6.29 and even 2.6.30 Kernels!
VMware Workstation 6.5.2 module patches/discussion: 2.6.29
VMware Workstation 6.5.2 module patches/discussion: 2.6.30
Sun has official Fedora 11 support (and now 2.6.31) with VirtualBox: VirtualBox 3.0.0 (if that’s your cup of tea)
Note: Obviously Fedora is the test bed for the QEMU/KVM merger so you can go that route as well, but I love VMware. ;0)
Here is a great article to get you moving on the QEMU/KVM way of life: Clik Me
HTH
Starting in Fedora 10 (but disabled by default) Red Hat Fedora started providing the KMS Framework.
Fedora – KMS page: Click Me
X.Org – KMS page : Click Me
Now if you’ve upgraded/installed the new Fedora 11 (or even Ubuntu 9.x etc.) KMS is enabled by default and you may have noticed there are new/still some regressions in the kernel and certain Intel and ATI cards may have issues.
If you’re having some crazy issues, fear not, you may have an answer here.

Ati/AMD Video Issues: Click Me
Note: This isn’t Fedora specific, you may have noticed you cant even enable desktop effects in Ubuntu 9.0.4 under certain cards (without de-blacklisting)
This is just the natural progression of trying to make things better and part of the growing pains that going with non-enterprise distros of Linux can give it’s users……but end the end, it will be worth it.
HTH.
If you are a conscientious system administrator, you like to keep tabs on your server by checking root’s email at least once a day, correct? If you manage more than one server, or get tired of having to log in to check your mail, you can redirect where email for the root user gets sent.
I ran into problems on Red Hat Enterprise 5.2 doing this, so I thought I’d post the resolution here.
This applies to RedHat Enterprise 4 & 5, and by association to Fedora and CentOS. It probably works on some other distros as well, but your mileage may vary.
I am constantly having to reset user passwords, as I use the “three failures and your account is locked” schema, as well as set passwords to expire every 60 days. Read the rest of this entry »
If you live in the USA, did you know that your tax dollars are being used for some really good purposes?
You better believe it. For example, the NSA provides some great guides and tools for securing your operating system, whether your are on a Mac, or running Windows, Linux, or Solaris.
Some of the guides can get a little complex (especially the Linux and Solaris ones), but even if you do some of what they suggest, you are increasing the security of your OS and are likely to learn a few things at the same time.
There are more resources from other parts of the government as well. Read the rest of this entry »

I hardly ever trust the coupon sites floating around on the net, but I figured what they hey, it can’t hurt to try one.
I’ve really been wanting a Dell Latitude D630 series (yeah it’s an older model, on the 800 bus etc.) but, it IS the perfect laptop when looking to run 100% of any version of Linux and works with all the major “Security Tool” CD’s. ;0) Read the rest of this entry »
