Best place to download RH

Okay *just* in case it IS my disks that are at fault I want to grap
another copy of disk 2. Can anyone suggest where I can go and get it in
less than 6 hours? (I've got cox and ncftp).

OR can anyone tell me how to run a md5sum on the disk image of a CD? in
other words if I have a disk in /mnt/cdrom can I do a md5sum of the
whole mount point?

Thanks,
Carl P.
