I noticed today that Cnews lets incoming control messages have their way (at least in creating groups). How can I make it so that the news administrator is notified every time a control request comes in (like Bnews) so that the news admin can create or destroy groups or change moderation as he sees fit? -- Todd Day | todd@ivucsb.sba.ca.us | ivucsb!todd@anise.acc.com "Santa Barbara - so many babes... so few who will talk to me."

In several recent messages, people have speculated without cause about alleged misfeatures in C news (aside: why do people insist on spelling "C news" as "Cnews"? if someone said "Cnews" to me, I'd say "Gesundheit!"). Todd Day's most spectacular groundless speculation is: > I noticed today that Cnews lets incoming control messages have > their way (at least in creating groups). How can I make it so > that the news administrator is notified every time a control > request comes in (like Bnews) so that the news admin can create > or destroy groups or change moderation as he sees fit? : stat; cd /usr/lib/newsbin/ctl; grep mail newgroup rmgroup newgroup: echo "newsgroup $1 was created by $SENDER." | mail $NEWSMASTER rmgroup:echo "rmgroup $1 says $SENDER" | mail $NEWSMASTER In future, would people posting reports of alleged bugs in C news please first check that they are running C news and try to verify the alleged bugs by examining the code (which often turns out to be shell scripts) to confirm that there is a non-zero probability that the alleged bug actually exists? -- Geoff Collyer utzoo!utstat!geoff, geoff@utstat.toronto.edu ``... skill such as yours is evidence of a misspent youth.'' - Herbert Spencer

Henry and I are in the business of providing tools, not solutions to the wrong problems. We cannot possibly guess what everyone in the world is going to want, nor do we want to distribute a gargantuan distribution consisting of the union of all possible wish lists. We are interested in genuine bug reports, but failing to behave like B news (as opposed to failing to meet RFC 1036) is not a bug. I'm afraid we don't have a lot of sympathy for people who can't be bothered to make one-line changes to shell scripts. If the distribution merely doesn't do what you want, you have the source and an editor. > I've noticed this too.

Again, read the source; newgroup and rmgroup do nothing destructive. newgroup creates the group and both newgroup and rmgroup send mail to $NEWSMASTER (usenet by default). If you don't want the new group, you probably want to change its active flag to x rather than deleting its active file entry, but even deleting the active entry is trivial.

OK, I put it kinda cryptically... Rephrasing... "How can I make it so that the news administrator is notified every time a control request comes in (like Bnews) WITHOUT THE NEW GROUP BEING CREATED, so that the news admin can create groups or change moderation as he sees fit?" I did get notified. What I meant, is, "Are there any flags in the config files that I should be setting so that groups are not created by the whims of a new administrator, but so that I am notified so *I* can go ahead and create these groups myself?" [I call it Cnews 'cause I keep the source in /usr/local/src/Cnews] After looking at the shell scripts (which I don't want to change myself for fear of being incompatible with future versions of Cnews), I see it's indeed impossible via any flag setting to accomplish what I want to above. What the C news gurus seem to be saying, is, we put all that stuff into shell scripts so *you* can change them easily. If you don't agree with our philosophy, fine, change those shell scripts. Is this indeed what you are saying? If so, and if you don't intend on updating the shells, I'll go ahead and do it. But as it is now, anybody new admin can make those dumb mistakes and moderate and create groups. Not destructive, but can be a pain. At least they can't remove groups. I don't mean to carp too much, 'cause I really do like most parts of C news... It's always the little things... -- Todd Day | todd@ivucsb.sba.ca.us | ivucsb!todd@anise.acc.com "Santa Barbara - so many babes... so few who will talk to me."

There is room for an almost unlimited number of configuration parameters to tweak various details of the software. There came a time when we had a choice of adding still more, or shipping the software. We shipped. C News as it stands does not provide every possible customization option. What it does provide, though, is a system that's easier for you to customize. We may eventually add the most popular customizations as configuration options, but we expect that there will always be people who want something unusual enough that they have to do it themselves. -- $10 million equals 18 PM | Henry Spencer at U of Toronto Zoology (Pentagon-Minutes). -Tom Neff | uunet!attcan!utzoo!henry henry@zoo.toronto.edu

This is a valid argument, IMHO. I hacked the scripts a little bit to get C news to run, and now I'm afraid to apply the latest patch for fear of breaking whatever it was that I had to change. I don't know if there is an (easy) general solution to this problem of local customizations and patches conflicting, but it seems to me that the most obvious ones ought to be taken care of at configuration time. The two important options (to me, at least) not handled at configuration time are auto/manual create/remove groups, and immediate/deferred input processing. The use of DBZ was another, but that's supposed to be standard next time around. BTW, C news wasn't any panacea here, even with DBZ. It only forced me to discover that our bottleneck was uncompress. It *does* seem more manageable, though, than B news. -- Rick Richardson | JetRoff "di"-troff to LaserJet Postprocessor|uunet!pcrat!dry2 PC Research,Inc.| Mail: uunet!pcrat!jetroff; For anon uucp do:|for Dhrystone 2 uunet!pcrat!rick| uucp jetroff!~jetuucp/file_list ~nuucp/. |submission forms. jetroff Wk2200-0300,Sa,Su ACU {2400,PEP} 12013898963 "" \d\r\d ogin: jetuucp

Insanity? It would make an interesting defence in a trial, that is
for certain. "You honour, my client clearly can not be held for his
actions. Why, he even lacks the mental faculties to have defined
NONEWGROUP in his B News configuration!"
Balderdash. We have NORMGROUP here because of its destructive
behaviour but newgroup messages are honoured. If the group is really
bogus, like talk.bizarre.nice, I'll rmgroup is soon enough. In the
meantime, junk gets a whole bunch of articles that my neighbours ship
me because they think the group is valid. If the status was changed
from unmoderated to moderated, it is mostly just an inconvenience for
a short while. If the status was made unmoderated when it had been
previously moderated, it is a pretty small window before someone sends
through a message correcting the error. For example when the fiasco
of a couple of months ago unmoderated a number of groups, two admins
(Gene and someone else whose name eludes me) sent out all the messages
necessary to correct the situation. All I had to do in all of that
was rmgroup rec.games.rpg.
Insanity indeed.

I will freely admit that it's a little easier to find and uncomment the NONEWSGROUPS during B-news installation than to know to look for and find the source and change it in C-news, but that does beg one point: Most novice administrators would leave NONEWSGROUPS off anyhow because they don't have the slightest idea of what happens when they leave it off. Even some non-novice administrators (like me - I contributed some of bug reports that were actually accepted by Geoff (! ;-)) in C-news Alpha) *still* leave NONEWSGROUPS off.
