I know that HDB UUCP knows about UUCP grades, but is there any way to limit the level of grades going out in a UUCP connection? Someone mentioned that it is specified in the Systems file, with a format like: sysname 2300-0500/G where the '/G' specifies the grade. My documentation (AT&T System V, for a AT&T 3B15) makes absolutely no mention of this feature anywhere. Does it exist? -- Stephen Corbesero flash@lehi3b15.UUCP VLSI Design Automation Lab usgcorb@vax1.cc.Lehigh.EDU Computer Science And Electrical Engineering, Lehigh University

Unfortunately, "runnning HDB" doesn't mean anything any more. There are at least 3 variants of HDB that I know of. Only one of them has the support for grades in it (the latest one). I "think" the absolute latest one that comes as part of System V.3.N supports grades. The earlier versions don't. I think most of the ones shipping for xenix do not support grades, nor does the version you can get from the toolchest. It is important to note that there are several versions around. Just because you have a Systems file instead of an L.sys doesn't mean you are running the most recent version of HDB. Its time to start labling the HDB variants just like we already label the "uucp" variants. (e.g. 4.3BSD uucp, microport HDB, etc) (Vendors: if you plan to ship HDB, PLEASE get the latest source directly from Honeyman. It fixes bugs that are NOT fixed on the version ATT is selling.) ---rick Maxim 1: Unix is what is running on Dennis Ritchies machine Maxim 2: HDB is what is running on Peter Honeymans machine!

AT&T System V doesn't support this feature, why I don't know... They on Sys V is only good for forcing jobs ahead of others. (ie. mail before news, no matter when mail was queued -- even after news) The format is D.sysGsequence for the uucp files, where sys is the system, G is the single grade letter and the sequence. By using different letters will change the sorting of the directory, and hence the priority of queued jobs. -Lenny -- US MAIL : Lenny Tropiano, ICUS Computer Group IIIII CCC U U SSS PO Box 1 I C U U S Islip Terrace, New York 11752 I C U U SS PHONE : (516) 968-8576 [H] (516) 582-5525 [W] I C U U S TELEX : 154232428 [ICUS] IIIII CCC UUU SSS AT&T MAIL: ...attmail!icus!lenny UUCP : ...{mtune, ihnp4, boulder, talcott, sbcs, bc-cis}!icus!lenny

Recently, I spent time on the AT&T Hotline on a not unrelated topic (StarLAN & UUCP). When my problem was solved, I asked about grades in AT&T BNU. After a 30 minute search of the source code, the tech replied that he could not find any mention of limiting grades as described above. My assumption is that AT&T does not supply graded transfers in its distribution UNIX. (What happens in the labs is another story :-) danno -- Daniel S.

In this case, you want to queue news at a lower grade than mail. (People seem to get mixed up about "higher" or "lower" grades. Consider letters with higher ASCII values to be of lower grades, just as 'F' is a lower report card grade than 'A'...) The default uux grade in my copy of HDB is 'N', hence your outgoing mail is probably queued at grade 'N', unless your mailer specifies otherwise. A simple experiment will tell what it really is, but I will assume 'N' at the moment. And of course, unless you have a late version of HDB, this won't work at all. (Mine doesn't honor grade sensitive transfers, and it's got SCCS ids of 2.??.) The conventional grade for news transfers is 'd' (see localize.4.3 in your 2.11 source directory) so you would add the argument "-gd" to uux in LIBDIR/sendbatch. And remember to fix UUXFLAGS in localize.sh so that the change sticks the next time you patch your news source. With these changes, you can make the downstream site's Systems entry something like: downstream Any/Z ACU 2400 ... Your mail queued at grade 'N' will then go any time (as well as anything else queued at grades [0-9A-Z]), while news will sit until downstream calls. You may also want to limit the amount of news queued for downstream, especially if they're a PC that calls only when the owner remembers to force a poll (arrggghhhh!!!!!)
romain@pyrnj.uucp (Romain Kang) (03/26/88)
[newsgroup, who's got the newsgroup?] The one way to be sure whether grading works in your version is to try graded transfers and see if they get through at the times you expect. For example, if you have downstream Any/Z,Any2301-0659 ACU ... you can try queuing a grade 'z' job during peak hours: $ uucp -r -gz foo downstream!~/ If it gets transmitted before late night hours, then grading doesn't work in your rev of HDB. [pedantic mode off] The bug that peter (as opposed to Peter) speaks of in an earlier message is that your uucico may still call downstream during the day, even if the only jobs in the queue have grades lower than 'Z'. C'est la vie...
