When finding the MTU I guess you will not always get the MTU size at the destination, but the smallest MTU on the path to the desti- nation. If doing ping to a destination, specifying the packetsize, this should probably determine the smallest MTU on the path, by trial and error. There are probably some applications doing this auto- matically, but I don't know of any. I presume you have already searched Google for MTU discovery?
