Well, I have been planning to launch this site for a while now. A place to pay homage to the all mighty terminal in all of its glory. Actually I’m sure some non-terminal things will get in here but really thats fine. Ultimately I hope this will be a place for people to waste a few minutes and maybe pick up a new tip.
My post on Automatic session logging and monitoring with GNU screen seems to have been well received. I have had more hits by far on that post today than ever before. I noticed a nagging issue with screen and a friend of mine Travis Cline pointed me to the fix.
Yes its been a while since I have checked in. Sorry I’ve just been too busy. But I have a great tip this time. Recently I had the need to do automatic session logging. A 3rd party was going to be logging into one of my servers to check out some software glitches that were happening. I love using GNU Screen for many shell tasks so using it for monitoring was logical. Screen is great for several reasons. First you can detach from it so you can leave the office, go home and re-attach and not have lost your place. Second, you can share another screen. It can be shared input or you can just watch what someone else is doing. Finally screen can do native logging. I wanted to automattically launch a screen session when somone logged in so if I happened to be on the server I could monitor them in real time. I also wanted a log of the session in case I wanted to look over it later or if I was not able to monitor the session live.
I am in the process of setting up Xen on one of my new servers. Just sticking some notes here. Will clean them up later `I am in the process of setting up Xen on one of my new servers.

I am in the process of setting up one of my new servers. Yes my old dual pIII machines are going to retire. They are going to live in a “retirement community” :P. Any way This time around I am going to use a mirror to protect my data. I never experienced a hardware failure before but I figure better safe than sorry right? So I am going to outline the steps needed to boot from a RAID0.
So what kind of performance should people expect from a disk or raid? How long should it take to create 100G file? time dd if=/dev/zero of=mako1 bs=65536 count=163840 A customer of ours is using this to create a 10G file and its taking about 20 minutes to create the file on a 12 drive raid 5 with 3ware. After setting ra again (in case the customer did not) and I got about 18 minutes on the same command.
