A users at my site came to me with an address that he could not get
to. The address contained ....!hamlet.stanford.edu!f.flex . I
started looking around in the map files and discovered that
.stanford.edu as well as .berkeley.edu are not listed in the map files
(and thus my pathalias software routes all of their addresses to
seismo since that is my closest .edu site). Can anyone tell me what
the deal is?

Routing that mail to seismo (or any other ARPAnet site) should work.

Well, I was not simply trying to make things work, but trying to make them work in the best way possible. For example, I have since found out that .ti.com is not listed in the maps either. We happen to talk to ti-csl which is in the .ti.com domain but uumail does not know this since it is not in the map files. Instead, user@host.ti.com gets routed to seismo. This is a general problem. It is probably something that the site administrators should add to their map entries but until then, is there a way to get reasonably accurate information about the domains. A list of gateway machines to domains would be nice even if the gateway is not on usenet. In that case, the path will go through the apprpriate place (like seismo). -- Perry Smith pedz@bobkat {ti-csl,infotel}!pollux!bobkat!pedz

This is a general problem. Will ti-csl understand if you send it the address ti-csl!foo.ti.com!user ? If not, it cannot be placed in the domains files, or things will break. If they do, it could be added, but things like this may be more complicated these days, since TI may not wish to pay Mark's group their fee. Remember, the whole idea of domains is so you don't need to know the address of every company in the known universe. You must know the address for ".com", but not ".foo.com" for all foo. -- - Joe Buck {hplabs,ihnp4,sun,ames}!oliveb!epimass!jbuck Entropic Processing, Inc., Cupertino, California

At Western we have access to NetNorth/BITNET and can hit a many of the .EDU sites through that network. For us, even if we were a full IP host, that's the "best" way -- it's the cheapest and pretty fast. So that's what we do. * How would I put this information into the maps? Assuming that * one could? That's one reason I've been a bit worried about the domain registry efforts of the three parties here in Canada (UUCP, NETNORTH, and CDN) --- each seems to think that the "best" method to get to the internet is through their network. None of these, not even the Internet itself, is the best way. * I believe that several .EDU sites on the IP are actually firing * mail over BITNET as their optimal route. Or at least I've seen * some queries to that effect. Any optimal solution ought to be taking advantage of the many different networks we have and not depending on just one. This requires though that sites be well integrated in terms of the many networks that hit them. Smail/Pathalias is fine for .UUCP routing but isn't going to work properly for us (yet it may someday). -- Title: Postmaster (E-mail) University of Western Ontario Telephone: (519) 661 2151 x6044 Postal: Computing and Communications Services Natural Sciences Centre University of Western Ontario London, Ontario N6A 5B7 Canada CDN: {postmaster/reggers}@julian.UWO.CDN BITNET: {postmaster/reggers}@uwovax.BITNET NETNORTH: {postmaster/reggers}@julian.UWO.NETNORTH UUCP: {postmaster/reggers}@julian.UUCP (...!watmath!julian..) -- -- Title: Postmaster (E-mail) University of Western Ontario Telephone: (519) 661 2151 x6044 Postal: Computing and Communications Services Natural Sciences Centre University of Western Ontario London, Ontario N6A 5B7 Canada CDN: {postmaster/reggers}@julian.UWO.CDN BITNET: {postmaster/reggers}@uwovax.BITNET NETNORTH: {postmaster/reggers}@julian.UWO.NETNORTH UUCP: {postmaster/reggers}@julian.UUCP (...!watmath!julian..)
