Many of the administrators who are new to linux have problem with opening file from a cdrom or to install application from a CD on a linux platform. The below steps must help you.
# mount /dev/cdrom /cdrom
Hope that helps...
# mount /dev/cdrom /cdrom
This will show following result:
mount: mount point /cdrom does not exist.
Now change the directory to / if you are not there:
Here create a directory to mount the CD using the following command:
# mkdir cdrom
To mount the D to the "cdrom" directory use the following command:
# mount /dev/cdrom /cdrom
Now change directory to /cdrom:
# cd /cdrom
browse the CD with the "ls" command.
To unmount the CD, change directory back to / followed by the unmount command.
# cd /
# umount cdrom.
Hope that helps...
