I'm a sysadmin for Sentry Data Systems. I do linux and clustering and networking, and enjoy instigating a good STONITH deathmatch when I get bored.

Work-wise, I'm a giant fan of the k.I.s.s. principle - keep I.T. simple, stupid. Don't make things any more complex than the features you need.

In my spare time, I renovate houses and ride herd on a pack of dogs with extreme mental issues. My background and career are both in systems. I look at systems, analyze them, and use them or make them better. I likeCFO DIY home stuff because the systems are simple and it's rewarding to figure em out and use them. How do I know the things I do? I have probably been there, broken that, ruined the other thing, and had to figure out how to fix all of them. we have this saying in my group of friends-who-renovate-houses: "Ask me how I know."

comment How to manage Xen virtual machines on shared SAN storage?
Look in your xend-config.sxp file -- the config settings your looking for start at about line 261 on my system, and are called xend-domain-lock, xend-domain-lock-path, and if you want to set up an external utility to manage it in another way, you can specify an external command to run with xend-domain-lock-utility.

comment Password expiration policies
Actually, the vast majority of attacks in our workplace come from students breaking into offices in an attempt to access tests or to change grades. In previous (non-academic) positions, the vast majority of attacks came from social engineering.

comment What is the best resource for really understanding Linux deeply
Linux being free and easily repairable in most cases is definitely a resource. The experience of starting with a broken system and being able to see into all it's parts (Unlike a commercial OS) is a huge strength, and the only way you learn how to research a problem and feel your way through it is to do it.

comment How Often Should I Update our Linux Server?
We have a cron script that runs the equivalent for our SLES/OpenSuSE boxes nightly; when it finds that it needs packages, it submits a ticket to the system administration queue in our trouble ticket system. (It keeps track of which ones it's submitted before in a file in /tmp so that it doesn't spam the queue.)

comment What is preventing you from deploying desktop Linux in your environment?
Yeah, to clarify: the problem with deploying linux in our environment is the users, not the software. However, it is a real problem. I'm hoping things get better when current college students, many of whom are used to OSX, get up to management.

comment Network equipment console cables
What, firing the dunce? No, that always solves the problem. ;) We use permanent labeling, and group them by 'class' -- it would be rare that we only have one piece of a particular model. So we've generally got three or four cables of the same type. That way, if a cable breaks, we can use one from a 'close' model and be relatively certain that it will work. Pinouts can change with hardware revs. In the case of the bricked KVM, he used a serial cable from an APC smart power supply on a Belkin KVM. Caused a small release of magic smoke.

... Why would making it a working copy chew up too much network drive space?

comment Extend Raid5 with a new HD (HP DL380 G3)
Sam, you won't see it unless you have a drive that the array can be expanded into. Sorry, I can't help you with the Windows side of things... I don't touch that stuff. Rots your brain and all that.
