I applaud the effort now under way to distribute path data in net.news.map. Timely and accurate information will go a long way to improving mail handling in the anarchy net. I expect the quality of the data will improve over time, nonetheless, I have stumbled across a few serious problems, along with some minor syntax errors. Zehntel claims to be aliased as alpha, while alpha is well known to mappers and to various btl hosts. Sri-tsc declares some uucp links, but is reachable only via the arpanet, leading to a familiar ambiguity. Some utah sites have the same problem. The following local hosts at sun are not unique: icarus btl, well known to mappers. ariel btl, well known to mappers. orion btl, well known to mappers. phoenix btl, well known to mappers. merlin btl, well known to mappers. phobos btl, well known to mappers. mars btl, may be an informal alias. venus btl, may be an informal alias. west btl, may be an informal alias. medusa masscomp local host. babel masscomp local host. asylum masscomp local host. comet instructional vax at ukc. galileo somewhere in italy, someday. rigel astronomy department at u. of chicago. "I doubt it" local hosts at sun: emerald same as teklabs!azure!crimson!emerald? prodigal same as bang!prodigal and cadre!prodigal? vixen same as linus!vixen? et same as axiom!et? saturn same as hplabs!saturn? titan same as wbux5!titan or utcsrgv!titan? for that matter, is wbux5!titan == utcsrgv!titan? Both sun and masscomp are vexed by sendmail syntax; they would like mail from, say, sun!medusa!user to look like it came from sun!user. I'm sure there's a way to do this -- can anyone help? A correct solution would build an appropriate unix-mail From line (in addition to the header-phile From: or Sender: line). Peter

<...> >The following [local] hosts [at sun] are not unique: >icarus btl, well known to mappers. >ariel btl, well known to mappers. etc. In other words: it's more than time to switch to domain addressing. Creating unique sitenames in a worldwide network is getting harder every day. And (re)routing would get a lot easier without every backbone having to know paths to all sites. Even a crude splitting into domains like usa, eur, aus etc. would do a lot of good already. -- Piet Beertema, CWI, Amsterdam ...{decvax,philabs}!mcvax!piet

Both sun and masscomp are vexed by sendmail syntax; they would like mail from, say, sun!medusa!user to look like it came from sun!user. I'm sure there's a way to do this -- can anyone help? A correct solution would build an appropriate unix-mail From line (in addition to the header-phile From: or Sender: line). It really isn't hard to arrange this. I'll enclose the ruleset 13 from cbosgd. The 3rd line is the one that does this, the others are local hacks to deal with other flavors of syntax. We use this to hide our local Suns from the outside - I'm really on cbpavo right now, but this will appear to come from cbosgd. R$+ $:$>5$1 convert to old style R$=U!$+ $2 strip local name R$+<@$=S> $1 mark@cbpavo -> mark R$+<@$+.UUCP> $2.UUCP!$1 xxx@foo.uucp -> foo.uucp!xxx R$+ $:$U!$1 stick on our host name R$=U!$=R:$+ $:$1!$3 ucbvax!ucbvax:xxx => ucbvax!xxx Note that this is the easy part. For an organization to make this work, all the machines must be centrally administered. In particular, it must be true that if user@workstation exists, user@gateway also exists and is owned by the same person. (Watch out for "root" and other non-human logins.) Also, people must arrange that mail to their name on the gateway will be forwarded to their favorite workstation. Sharing the same password file among all the machines is one easy way to make this work, but you still need forwarding from the gateway.
