CentOS / Redhat: Chroot And Mount Raid Or Actual Hard Disk From Rescue Kernel / CD

Posted on in Categories last updated June 24, 2010

Something is wrong with my RHEL networking configuration so I booted using my ISPs remote rescue kernel mode to fix my system. How do I mount and chroot into actual installation to fix the problem? How do I boot from any Live Linux CD and chroot into /dev/sda1 or /dev/md0 to fix the problem or recover the data?

FreeBSD: Permanently Delete / Remove Files With Shred

Posted on in Categories last updated June 23, 2010

I‘m going to upgrade my FreeBSD 7.x server hard disks and going to send back the original 73GB hard disk to my vendor. I wanted to make sure that no one should able to use my personal data from old hard disk, especially files stored in /home/you/projects directory. I know how to use sDelete under MS-Windows to delete a file permanently. How do I permanently erase files under FreeBSD operating systems?
