[Taken from Bruce Lilly's recent posting] Analysis of the latest UUCP maps available here as of today revealed the following backlinks, i.e. missing (undeclared) links for which the reverse link is declared in the maps. [BTW, pathalias can be made to emit this information by supplying more than one -v flag; e.g. pathalias -vv ...] As the primary purpose of the UUCP maps is to describe the UUCP network for the purpose of mail routing, and as a reverse link is necessary (e.g for bounce messages), a missing link indicates an inconsistency in the map data which may result in unusable or unreliable paths. One way the inconsistency can arise is if a link is removed from one site's map entry (when the link is no longer functional), but the other site's map entry is not revised. Certainly in this case the link (either direction) cannot be counted on to work. It is also possible that one direction of a link is not declared by the corresponding site due to indolence, ineptness, ignorance, selfishness, etc. In this case as well, the link can probably not be relied upon. Finally, it is possible that the forward link is a typographical error, e.g. a link may be declared where an alias is intended (i.e. the '=' is left out). abdul <- clif ackpfft <- wsu-cs ackphfft <- modcomp f117a <- m-net genias <- wybbs mastro <- sycom meros <- clmqt miccal <- fernwood micro <- wsu-cs myamiga <- mixcom nthstone <- irie orage <- ombrage psgi <- vela therip <- wybbs unisysmi <- sharkey ylum <- lokkur
