1. Insert cd-rom into server's cd-rom drive and mount cd-rom
mount /dev/cdrom /mnt/cdrom
2. Install RPM through rpm program
rpm -Uvh /mnt/cdrom/e-smith/RPMS/man-1.5i2-0.7x.i386.rpm
(tip: use the auto-completion feature of your shell -> type above path up to 'man-', then press .)
3. When you're done with cd-rom, unmount it
umount /mnt/cdrom
(yes, that's 'umount', not 'unmount'; or alternatively:)
eject
4. With man installed, read the man pages for 'rpm' and 'mount'
