OpenWRT and a SMB Share - GilesOrr.com

This is an outline of what I did to create a SMB share on an external hard drive attached to an OpenWRT router. This would also let you attach a USB storage device to your router without setting up Samba, or you could set up Samba without having external storage ... but to me it makes more sense to have the two together.
