Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

My little PXE experiment has gone mad

Posted 11-25-2012 at 06:10 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

Ok, so in my original PXE experiment blog post, I outlined getting everything setup and working for basic pxe boot options (isos that don't require additional work other than memdisk, menu.c32, etc...).

I've taken the liberty of sub-menuing and beautifying the configuration a bit, and I've added two of my favorite live dvds (BackTrack and Linux Mint). Here is my /tftp/pxelinux.cfg/default file now:

Code:
DEFAULT vesamenu.c32

My little PXE experiment?

Posted 11-24-2012 at 04:28 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

My wife recently started having odd issues with her main gaming rig rebooting during intensive pvp fights, so she asked me to look into diagnostics programs so we can see what the issue is. (After discussing the issue with a friend, my wife determined that it was her power supply, and we've ordered one).

Unfortunately, the bug to setup a PXE environment, loaded with diagnostics, utilities, antivirus, etc... had been planted, and I couldn't let the idea go. I've never set one up,...

The unix philosophy is not strong in this one.

I took my RHCSA test today (non-official pre-test). I finished all ~20 objectives in 30 minutes, minus one objective regarding quotas. Hrmmm...can't seem to recall the quota init command (and I've never really used Linux quotas before...this may get interesting). No worries, man -k to the rescue!

man -k quota

Well, ok, there are the commands for managing quotas, checking quotas, reporting on quotas, etc...but no "set up quotas". See, when I try to run...

The Lost Art of Situational Awareness

Posted 10-21-2012 at 08:39 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I was driving to the store tonight. As I drove through the (seemingly) deserted stretch of parking lot, I came up to a man, woman, and child walking through the dimly lit area. I noticed that they were uncomfortably close to the road, so I started to fade to the left to avoid them. As I approached, the man continued narrowing the gap between my 2 1/2 ton vehicle and his body. His wife wisely stayed to the right with their child...but then an amazing thing happened...

In preparation for an anniversary

Posted 10-16-2012 at 06:20 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

It's been nearly a year since I started working at Rackspace, so I've been thinking alot over the past few days about how my life has changed since I started this insane wild ride. Aside from the expected "I live in San Antonio now", or "I make better money now", or even "I can't begin to explain how much I've learned in the past year", there are deeper, more subtle changes that have had oddly profound effects on my day to day life.

For starters, its...
