When feeding another site 'spike', upon successful delivery of each batch of news, I get a mail message from spike!uucp telling me that uux completed normally. We are a pyramid 90x running OSx 4.0 (BSD universe) and news 2.11, patchlevel 14. We also feed another site, 'bourbon', and both are set up in the same way, yet we don't get mail from bourbon!uucp after each successful batch is delivered. The entries in the sys file are as follows [carriage return added here to make the line fit in 80 columns]: bourbon:world,comp,sci,news,rec,soc,talk,alt,misc,net,mod,na,usa,la,no,tulane, to.bourbon:F:/usr/spool/batch/bourbon spike:world,comp,sci,news,rec,soc,talk,alt,misc,net,mod,na,usa,la,no,to.spike: F:/usr/spool/batch/spike Then cron runs /usr/lib/news/sendbatch, a script which calls uux ___with the -z option___ (tells to send mail only on failure). And yes, our uux does support -z. Is this perhaps a BSD / SYS V incompatibility? (bourbon is BSD and spike is SYS V) Or is there something more obvious that I have missed? Any help appreciated. It is a little disconcerting to come in Monday morning and find 280 messages in your mailbox, only to realize they're from uucp. :-) Thanks. -- Marilyn Wulfekuhler | USENET: pyramid!rex!mrw Computer Science Dept | INTERNET: mrw@rex.cs.tulane.edu Tulane University | BITNET: mrw%rex.cs.tulane.edu@relay.cs.net New Orleans, La. 70118

All UUCPs were not created equal. It doesn't matter much what UUCP you are
running; your neighbors' uuxqt daemon will either respect your wishes about
mailing of thank-you notes or it will not.
Rick Adams' BSD UUCP and Honeyman's HDB UUCP will respect their neighbors'
-n (don't send any mail no matter what) and -z (send mail only if the remote
command execution returns an error exit status). Sys-III UUCP will not
respect either request. Sys-Vr2 (pre-HDB) respects -n but not -z.
-n and -z are arguments to the uux command you use to queue a batch to your
neighbor; they do into one of the control-card files sent by UUCP to the
remote system, and the remote system will either know about them or not.
Ultrix UUCP, by the way, knows about -n but not about -z. :-(.

Yes there seems to be a case of SYSV and BSD incompatibility on how to interpret the options to uux: On SYSV systems the -z option means "Send success notification to the user" whereas on BSD (According to my 4.3BSD manual) -z option means "Notify the user only if the command fail". Beware there is other nasty traps hidden in uux when shifting between BSD and SYSV. Some options are purely SYSV like -b, -sFILE and some are BSD Only: -l and -L. Beware if you're using the -n option on BSD it means "Do not notify the user when the command completes" and on SYSV "Do not notify the user if the command fails" Best Regards, Kim Chr.

First, some old uuxqt's do not support -z; you will have to find out from your neighbor whether this is the case with his. Second, beware that the semantics of the -z option are not the same in all uux's: in HDB, the old -z behavior is the *default*, and an explicit -z requests notification if the command *succeeds*. (Note that this is a user-interface difference in uux, not a difference in what is sent: HDB without -z sends what a non-HDB uux would send with -z.) -- Anyone who buys Wisconsin cheese is| Henry Spencer at U of Toronto Zoology a traitor to mankind. --Pournelle |uunet!mnetor!utzoo! henry @zoo.toronto.edu

The uux man page from the October 1984 issue of the Basic Networking Utilities Software Information Bulletin for System V Release 2.0 has the following to say about the -z option to uux: -z Send success notification to the user. This is contrary to what one would expect from reading the news 211 installation documentation. Perhaps you can modify the sendbatch script to not use the -z option when spooling news batches for the Sys V site?

My uux behaves different from all those I have seen discussed here.
It is supposed to be SysV (Microport System V/AT). The manual
says that -n sends no notification to user. There is no mention
of -z (it deosn't seem to do anything).
