Creating ISO Image Using DD Command

First, put the CD/DVD you want to make image into your optical drive, do not mount that CD/DVD.

If it was mounted automatically, unmount it with this command:
# umount /[mount]/[directory]

Then, do this command to create your ISO:
# dd if=/dev/cdrom of=/tmp/[isoname].iso
  • if=/dev/cdrom is the source
  • of=/tmp/[isoname].iso is the filename of the ISO you create
Or you could use the long option:
# dd if= of= bs= skip=< > seek=< > conv= count=< >
for bs (byte size), usually some power of 2, not less than 512 bytes, but can be any reasonable number (512, 1024, 2048, 4096, 8192, 16384)

OpenFire Server for Broadcast IM

These are some screenshoot of my OpenFire server configuration, I use this as an integrated service to communicate with all of my colleagues in my department. This way, we can share any update information in a more efficient and simple way :)
