Converting a disk to an iso image is easier to do in Linux than in other operating system. dd bs=2k if=/dev/cdrom of=~/disk_image.iso
Being my first Linux conference, overall I had a really good time. Seeing and talking to a lot of famous Open Source figures was pretty kool. I only managed to see four different talks.

I’m a sysadmin once again.
After 5 months of studying, I finally took the CompTIA Linux+ certification exam today. My study consisted of reading two books (Sybex CompTIA Linux+ and Linux+ 2005 in Depth), on-line tutorials, and a web based program called “TestOut Linux+ LabSim” that my school provides. The exam is by and far the most difficult CompTIA certification […]
Well, instead of spending Saturday night wasting my time at the mall or at that place people call movie theaters, I got a chance to play around with OpenSSH more in depth. I use ssh to log into my server practically every single day, but I really wasn’t aware all of its actual capabilities. After […]
