The uucico program supplied with Tandy 3.2 Xenix is sick. If I have an eight-letter sitename, such as 'jpradley', this will work fine for anyone initiating a uucp contact to 'jpradley'. But if site 'jpradley' calls another, it transmits its name as 'jpradle', truncating to seven letters. Any attempt by my uucico to login as 'Ujpradley' on a remote machine will fail, because my uucico will send that as 'ujpradley', translating upper-case to lower-case. Any patches for this malevlolent behavior? -- Jean-Pierre Radley Honi soit jpr@dasys1.UUCP New York, New York qui mal ...!hombre!jpradley!jpr CIS: 76120,1341 y pense ...!hombre!trigere!jpr

The uucp that comes with the Tandy 6000 is a UNIX Version 7-derived version. Host names are supposed to be limited to 7 characters. (This isn't mentioned in the documentation anywhere I can find quickly.). This is unlike the more modern System V versions of uucp, some of which require the name to be unique in *SIX* characters. The main reason for the 7-character limit is that in order to create a temporary file name of the form: <C, D, or X>.<system name><gradeletter><4-character sequence #> and given that file names are limited to 14 characters, this limits the system name to 7 characters. This is difficult to change. 4.2BSD did, but they broke a lot of code in the process. >But if site 'jpradley' calls another, it transmits its name as 'jpradle', >truncating to seven letters. >Any attempt by my uucico to login as 'Ujpradley' on a remote machine will Login names are limited to 8 characters. Uucico doesn't know or care about this, though. >fail, because my uucico will send that as 'ujpradley', translating >upper-case to lower-case. uucico does not do this. The getty on the other end (which I presume is another 6000) is doing it. This seems a little strange, but UNIX System III (which Tandy 3.2 is derived from) does it this way, and it makes it possible for people with upper-case-only terminals to log in on all logins by effectively prohibiting mixed-case and upper-case login names. (Someone is going to groan that upper-case-only terminals are ancient, and they are right). I do know that if a later release were to *STOP* downcasing login names, there would be a loud cry about things breaking. This happened locally when someone started informally distributing an auto-bauding getty that didn't do this, and lots of uucp connections broke, especially because of the U<system name> convention for the login name, and some users complained At least one version of System V getty still downcases login names. I don't think the more recent ones do. >Any patches for this malevlolent behavior? 1) Fix your host name to be 7 characters or less. I think the net-wide acceptable list of characters is a-z, 0-9, "_", and "-". 2) If the ONLY problem is how your system is identified to another system that supports longer host names, find the string "%.7s -Q%d %s" in uucico and change the 7 to an 8. I have not tested this. You had still better have a host name that is *UNIQUE* in the first 7 characters (well, because of System V, 6 characters). Note that you may have still more problems with an 8-character system name. If you have to put your own system name in USERFILE, I suggest putting it in twice on duplicate lines, one chopped to 7 characters, and one not. There is some inconsistency in chopping system names in control files to 7 characters, and in some contexts "jpradley" and "jpradle" are different names. There are some mailers around that chop system names to 7 or 8 characters. This can make it painful to reply to mail originating from or passing through a system with a long name. "microsoft", for instance, is likely to end up "microso" or "microsof" in the return address on the From_ line. Gordon L.

The getty on the other end (which I presume >is another 6000) is doing it. At site 'jpradley' (Tandy 6000): I cannot employ Ujpradley as a login name from site 'trigere' (also a Tandy 6000). I must avoid that capital 'U'. But at the same 'jpradley' site, the login name 'Uhombre' is quite nicely used by a (non-Tandy) machine for a uucp login. But from what you said, if it's the getty on the called machine that does a "_tolower()", how can it do it selectively when getty has no idea about the nature of the calling device? Same getty is answering all calls, but different uucico's are calling... -- Jean-Pierre Radley Honi soit jpr@dasys1.UUCP New York, New York qui mal ...!hombre!jpradley!jpr CIS: 76120,1341 y pense ...!hombre!trigere!jpr
