There are a large number of UUCP/Internet gateways scattered around the world right now. The problem is that there is no way to get this information in a useful form. What I would like is for the UUCP Maps to start listing this information and for pathalias to start using it. This would help in two ways. First if we assume that all UUCP/Internet gateways can talk to each other directly (at very low cost via the Internet) then shorter, more direct paths can be generated by pathalias. For example, cwjcc and uunet are both Internet sites and can talk to each other directly. But pathalias doesn't know that so it generates the path: "mailrus!ames!mimsy!uunet!%s" And before I added mailrus to our maps it was much longer! Arpatext was supposed to solve this problem but it doesn't work. There are too many name collisions between Arpanet and UUCP hosts. This information can also be used to automatically generate a list of forwarders. The forwarder for any registered .uucp site could be the nearest registered UUCP/Internet gateway. If enough gateways are listed the load on each site would be small. Of course, if only a few gateways declare themselves then we are back to choice one above. :-( Of course this is all just mental gymnastics and not intended to reflect reality in any way. Use it as you see fit. :-) -- Edward M. Rynes Jennings Computing Center "Hey!!! Somebody stole my quote!" Case Western Reserve University Cleveland, OH 44106 (216) 368-2982
