I see your apache's default "It works" page when I hit that URL with my browser (assuming that's your linode box).
If you desperately need to shunt some files out of it quickly, use that address as your vhost's 'ServerName', point it at a filesystem path, and let Apache serve an index of that location to your other person.
So, for instance, you could make a directory in /srv/www/temporary_just_for_now/, and then make an Apache virtualhost which serves from /srv/www/temporary_just_for_now as its DocumentRoot, with Indexes on and with the ServerName set to li280-180.members.linode.com with the name based virtualhost option.
