Bungling Sys Admin Gets It Right

Wanted to point out an excellent post on The Bungling Sys Admin Blog. It's a response to TaoSecurity's Recommendations for Introduction to UNIX post. Bejtlich, who tends to be a bit of a FreeBSD homer, recommends FreeBSD with Ubuntu and/or Debian as alternatives.

Matt, who has about 10 years of corporate linux administration expirence under his belt, makes an excellent counterpoint. His arguement is, if you are going to spend the time to learn, why not learn on a distribution that there is a high probability you will encounter in a real world production environment? He offers up Red Hat Enterprise Linux, CentOS, and Solaris as much more applicable alternatives.

I wholeheartedly agree with both both the choice of OS's and the reasoning behind them. Although I do have specific figures to back up my assertions, I would say that based on my expirences, these 3 OS's compose the lion's share of the *NIX market place and that if you were going to be maintaining a unix/linux based system in a real worl corporate environment, very high likely hood it will be one of these.

Cudo's to Matt for hitting the nail squarely on the head.

Hi, this is Joe. I am trying to install VMware server on host Centos 5.5 and ran into this issue

What is the location of the directory of C header files that match your running
kernel? [/usr/src/linux/include]

and i created folder
mkdir /usr/src/linux
cd /usr/src/linux
then created the C header

ln -s /lib/modules/2.6.18-194.11.4.el5xen/build/include include

and still it didnot work..please help whenever you can. My email address is

Ensure you have kernel-headers and kernel-devel packages installed with:

# rpm -qa | grep kernel-headers

# rpm -qa | grep kernel-devel

If not installed:

# yum -y kernel-headers kernel-devel

Good luck!
