first of all u have to get the diver of your CD or DVD

[root@viren ~]# eject -n
eject: device is `/dev/hdc'

the device driver is /dev/hdc

now mount the cdrom

#mount /dev/hdc /mnt/cdrom


create this directory cdrom if in case it doesn't exist



and in case u want to use this command as a shortcut

#mount /mnt/cdrom

then

#ln -s /dev/hdc /mnt/cdrom




Happy Mounting
