root@mjbtn.UUCP (The Super User) (02/16/88)
I have recently had a user request the ability to correspond with a colleague
who is on CSNET. I have also made some attempts to send mail back and forth
between a user on a BITNET site, but I could never get mail to come back to
me here on UUCP. Can anyone out there PLEASE give me a thorough lesson in
addressing (using pathalias and domains) net mail between various networks.
I need to be able to go both ways. I know it is fairly straightforward once
you understand it, but when you don't, it is impossible.
I would be most appreciative for any advise and suggestions. Thank you.

UUCP to Bitnet: route the message through psuvax1!foo.bitnet!user Bitnet to UUCP: likely a no-op. Many Bitnet mailers follow an older standard and cannot accept anything but user@site syntax, where site has to be in their tables and user has to be shorter than 8 characters. For example, even though this university has a Bitnet gateway that will forward mail (mailing to lamy@ai.utoronto or lamy@ai.toronto.edu will work on correctly configured and up to par Bitnet sites), many Bitnet sites simply cannot reach me that way. UUCP to Internet: route through one of many major machines, uunet being the canonical example. uunet!ai.toronto.edu!user should work. Internet to UUCP: Two possibilities, depending on the mailers (assuming the machine does not understand user@machine.uucp already). Again using uunet as the canonical gateway (any other will do). machine1!machine2!user@uunet.uu.net should work fine. Other gateways prefer user%machine1%machine2@ga.te.way uunet dislikes the second form. Any gateway that complies with RFC 976 should handle them (the bigger universities with Usenet access are likely candidates).

I've been having no problem getting from UUCP to the ARPANET and
BITNET, but I haven't had any need to contact anyone on CSNET.
If anyone knows of better ways to get to these networks I'd be more
than happy to hear them.
ARPANET:
send uunet!node.domain.xxx.ARPA!userid
receive userid%nodename.UUCP@seismo.gss.gov
BITNET:
send uunet!bitnet-node.BITNET!userid
receive userid%nodename.uucp@seismo.css.gov.BITNET
OR
send ...!psuvax1!bitnet-node.BITNET!userid
receive userid%nodename.uucp@psuvax1.psu.{bitnet,psu.edu,uucp}
CSNET: {---- never tried ----}
send uunet!relay.cs.net!csnet-node!user-id
receive userid$nodename@relay.cs.net
Unfortunately, as I said, I've never tried this CSNET addressing.

This didn't used to happen. We have corrected this problem by adding uppercase aliases. We have used the same syntax for going to CSNET as for going out to BITNET: we simply specify the network following the host name and separated with a period, as, for example, carleton.csnet or amherst.bitnet. CSNET mail seems to take longer than BITNET mail for some reason.

OK, since you asked, here's how things look from the UUCP world, if you're operating without benefit of smail: >ARPANET: > send uunet!node.domain.xxx.ARPA!userid There's no such thing as a subdomain of .ARPA. You probably meant to say something more like "uunet!node.sub.dom.ain!userid". Iff the machine really is on the ARPAnet proper, then ".sub.dom.ain" will be ".ARPA". > receive userid%nodename.UUCP@seismo.gss.gov Not only is it "seismo.Css.gov", but it's no longer doing what you want it to do. If your domain isn't in the UUCP maps, and/or nobody is a mail exchanger (MX) for you, would more properly be addressed as "userid%nodename.uucp@uunet.uu.net". >BITNET: > send uunet!bitnet-node.BITNET!userid Right! > receive userid%nodename.uucp@seismo.css.gov.BITNET Again, say something more like "userid%nodename.uucp@uunet.uu.net", but this entirely depends upon whether the user agent and mailer on the Bitnet end can handle domains. > OR > send ...!psuvax1!bitnet-node.BITNET!userid This is your best bet. > receive userid%nodename.uucp@psuvax1.psu.{bitnet,psu.edu,uucp} Again, this depends upon the sanity of the mail software on the Bitnet machine. The closest you could get might be "userid%nodename.uucp@psuvax1", because psuvax1 is the way that machine looks from the Bitnet side of things. >CSNET: {---- never tried ----} > send uunet!relay.cs.net!csnet-node!user-id > receive userid$nodename@relay.cs.net The CSnet relay systems are part of the ARPA-Internet domain scheme, and you can use the same conventions as described above. -=- Bob Sutterfield, Department of Computer and Information Science The Ohio State University; 2036 Neil Ave. Columbus OH USA 43210-1277 bob@cis.ohio-state.edu or ...!cbosgd!osu-cis!bob

The .ARPA domain was originally created to ease the transition from a domainless hostname system to the domain name system. The idea was to first get everybody used to having domain names by tacking a ".ARPA" on the end of their names (as MIT-XX became MIT-XX.ARPA). Then they would change from the .ARPA domain to their own organization's domain (MIT-XX.ARPA becomes XX.LCS.MIT.EDU - LCS = Laboratory for Computer Science for those who are curious). As of yet, not everybody has their own domains - MILNET hosts in particular have been very slow about this since the DDN wanted think about it for a long time. So there are some hosts still using .ARPA but they are not all on the ARPANET itself and in the end the intention is that *no one* should be using .ARPA. XX.LCS.MIT.EDU is on the ARPANET; its proper name is in the MIT.EDU domain. Domains identify organizations, not networks. -- - john romkey ...harvard!spdcc!kaos!romkey romkey@kaos.uucp romkey@xx.lcs.mit.edu

> Another problem we have encountered with mail coming to UUCP from BITNET > is that recently some of it has been coming in with upshifted userids. Yeah, and upshifted host names, in some cases. Which brings up a question I've had for some time, and which TFM doesn't seem to answer: Is there a way to hostname aliasing with various versions of uucp? I'm most interested in BNU (hdb), as that's what's running here, but I'm sure others would like to hear the answer for their system. There are several reasons for wanting this. For instance, one of my links is to mit-eddie (along with half of New England, I think). It'd be real nice if I could say "eddie!..." rather than "mit-eddie!...". Yes, I really am that lazy. I've also gotten mail with "MIT-EDDIE" in the path, and it'd be nice if the mailer here could be made to handle responses without first bouncing them back to me for further editing. Now, I could of course intercept /bin/mail and /bin/rmail, and add my own lookup to it. Maybe I'd call the database "/usr/lib/aliases" or something like that. But perhaps it's already there in the code, and they just didn't bother telling me about it. Anyone know? -- John Chambers <{adelie,ima,maynard,mit-eddie}!minya!{jc,root}> (617/484-6393)

UUCP is not the correct place to do hostname aliasing, except possibly for case sensitivity. I could not be too hard to fix the various versions of UUCP to ignore alphabetic case when checking for the hostname. Even easier would be a simple modification to uucp/uux to convert host names on input to lower case. Upper case hostnames are a real drag when "pathalias -i" is the approved technique to build routing tables. >There are several reasons for wanting this. For instance, one of my links >is to mit-eddie (along with half of New England, I think). It'd be real >nice if I could say "eddie!..." rather than "mit-eddie!...". Yes, I really >am that lazy. I've also gotten mail with "MIT-EDDIE" in the path, and it'd >be nice if the mailer here could be made to handle responses without first >bouncing them back to me for further editing. The mail router in use at NCR allows this. The 'next' information source is used to look up simple host names in UUCP paths. For example ncr-sd's configuration file has the line NEXTINFO sdcsvax ucsd!%s # backbone changed which re-routes mail from sdcsvax to ucsd since the functions of sdcsvax mave been replaced by ucsd. The host name ucsd is then looked up in the 'next' information source as well; it will be found in a sorted file as ucsd via-uux:ucsd!%s which routes it to the "via-uux" mailer, which then ships it via UUCP to ucsd. The line also replaces UCSD, uCsD or UCsd with ucsd, forcing ucsd to the correct alphabetic case. Other mailers may be added at the drop of a hat by just adding a few lines to the mail router configuration file. This allows multiple Message Transport Agents to be used, including PMDF, CompuServe and BSMTP. ncr-sd currently has 13 mailers defined. The most interesting one is the "nameserver" mailer, which looks up names address to the domain name SanDiego.NCR.COM using a separate program. The matching algorithm currently in use is fuzzy so mail mis-addressed to Mutt.Ostello@SanDiego.NCR.COM will still get to me. -- Matt Costello <matt.costello@SanDiego.NCR.COM> +1 619 485 2926 <matt.costello%SanDiego.NCR.COM@Relay.CS.NET> {ucsd,cbosgd,pyramid,nosc.ARPA}!ncr-sd!matt
