DAY-TO-DAY OPERATIONAL QUESTIONS
=====================================================================
------------------------------
Subject: How do I create all those directories in the newsspool?
Q: For example, if you receive comp.sys.amiga.applications, do you
have to mkdir /var/spool/news/comp/sys/amiga/applications?
A: Nope. innd creates the directory for you the first time you
receive an article for that newsgroup.
------------------------------
Subject: Safe way to edit the "active" file?
First of all, you could manipulate the active file using the ctlinnd
"newgroup", "rmgroup" and "changegroup" commands. However, sometimes
you just need to do a lot of editing all at once:
The following sequence is the shortest:
ctlinnd pause "edit active"
[do something to the active file]
ctlinnd reload active "edit active"
ctlinnd go "edit active"
Simple! No need to "flush" since the "pause" does that.
> What if I need to delete 3000 lines from my active file?
I would definately edit the active file manually (using
the above procedure).
> What if I need to delete 10 lines from my active file?
For a couple quick changes, I recommend using "ctlinnd". This is a
little slow because all channels are closed and reopened after each
"rmgroup", "newgroup", and "changegroup". However, it's easier than
remembering the above sequence.
DO NOT THROTTLE THE SERVER WHEN DOING MULTIPLE rmgroup COMMANDS. There
is a bug in INN (all versions) that will shred your active file if you
do multiple "rmgroup" messages while the server if throttled. This is
a common mistake. People think the "rmgroup"'s will go faster if the
server is throttled. It will go faster, it will also shred your active
file.
If you have a large number of groups to remove or create, you can use
awk to write a script to do the work for you.
% cat thelist
alt.foo.bar
alt.delete.me
comp.sys.mac
% awk <thelist '{ print "ctlinnd rmgroup " $1 }'
ctlinnd rmgroup alt.foo.bar
ctlinnd rmgroup alt.delete.me
ctlinnd rmgroup comp.sys.mac
Now, you can either send the output of that to "| sh -x",
or you can redirect the output to a file, and "source" the
file.
If you want to create a bunch of newsgroups, the awk
command might be like this:
% awk <thelist \
'{ print "ctlinnd newgroup " $1 " y user@host" }' | sh -x
------------------------------
Subject: What's the best way to upgrade to a new version of INN?
First, you should read the README and the Install.ms (yes, read
them both... again). Things change in new versions.
Second, the README explains how to do an upgrade. This document
is redundent, but explains the procedure in more detail.
STEP 1: Copy the values in the old config.data to your new config.data.
You can do this automaticly with this trick:
% cd config
% make subst
% cp config.dist config.data
% ./subst -f {OLDFILE} config.data
where "{OLDFILE}" names your old config.data file.
STEP 2: Edit the config.data to see if you want to change any of
the new settings that didn't exist in the old version's config.data
file.
STEP 3: Compile everything:
% cd $INN
% make world
STEP 4: When you feel you are ready to install the new files shut the old daemon:
% ctlinnd shutdown 'upgrade in progress'
[ kill innwatch by hand if you need to ]
STEP 4: Install the new files:
% cd $INN
% make update
STEP 5: Now update all your $INN/site files to be the same as they were
for your old software. "cd $INN/site ; make diff-installed" will tell
you what's different between the files in /usr/lib/news and $INN/site.
If you only make changes in the $INN/site directory and use "make
install" to copy them into place you'll save your self a lot of
trouble. Read $INN/site/Makefile for more interesting things that
"make" can do.
STEP 6: When you feel you are ready to install the new $INN/site files:
# cd $INN/site
# make install
STEP 7: Re-start the system:
% sh /usr/lib/news/etc/rc.news
STEP 8: If everything was done right you should be up and running.
Part 2 of the FAQ gives tips on testing your configuration.
------------------------------
Subject: How do I talk to innd from C or Perl?
Rich Salz says:
If you are writing C, look at doc/inndcomm.3 and include/inndcomm.h;
they include all you need to do any ctlinnd command (in fact, ctlinnd
itself is little more than a call to the library).
Hacking up a Perl subroutine that spoke to innd's Unix-domain control
socket should be fairly straightforward but hasn't yet been written.
------------------------------
Subject: After a crash.
"What do I do after a system crash?"
INN handles crashes pretty well. If there are any problems they
get cleaned up by the nightly expire. About once a month you
might want to run "makehistory -buv" to look for "lost" articles.
Check the man page for "makehistory" for more information.
=====================================================================
INN IS RUNNING, BUT I HAVE THIS SMALL PROBLEM...
=====================================================================
------------------------------
Subject: Suddenly my active and history files are owned by root!
rc.news runs from root. After that, everything else should run as
news. It sounds like you've run news.daily as root by mistake. Make
sure all your cron jobs run as news and you'll be fine.
If you have an old "cron" system, you might consider replacing yours
with one of the many public domain replacements. If you can't create
a different "crontab" for each user, the idiom is:
0 * * * * * su news -c '/do/this/as/news'
------------------------------
Subject: How come my host name comes out twice in the Path line?
The INN server puts its name in the Path line of every article that it
receives. Obviously, it has to do this. The default configuration has
inews put the local host in the Path header. If nobody posts on the
server and you use fully-qualified domain names on your workstations,
then everything works the right way. (If `hostname` doesn't give an
FQDN on your machine, you can work-around this by setting the "domain"
value in inn.conf; remember that innd never re-reads inn.conf. You
must "ctlinnd shutdown x" and then re-start the server). Many people
don't want the client machines to put their name in the Path header.
To do this, set INEWS_PATH to DONT. Finally, let me say that it is
probably a mistake to have a "pathhost" line on any machine other than
your server if you set INEWS_PATH to DO. If you doubt this, please
trace the article flow for yourself. If you are curious about the
effect of INEWS_PATH, read the nroff source -- not the formatted
output -- of doc/inews.1
------------------------------
Subject: Expire had problems last night, and while I fixed the
problem, it still won't run.
When expire starts up it "reserves" the server so that nobody else can
pause or throttle it. This prevents anyone else from coming in and
modifying the history database. If expire bails out because of a bad
error (e.g., your expire.ctl has syntax errors) it leaves the server
reserved so that no maintenance will be done until a good expire run has
occurred. To unblock the server, use the ctlinnd "reserve" command with
an empty string argument.
------------------------------
Subject: expire reports "Group not matched (removed?) --
Using default expiration"
Expire says:
Group not matched (removed?) alt.techno-shamanism -- Using default expiration
Group not matched (removed?) misc.computers.forsale -- Using default expiration
Group not matched (removed?) de.rec.sf.startrek -- Using default expiration
That just means that you've removed those newsgroups groups and expire
is slowly removing articles from the spool as they expire. Eventually
the articles will all have been deleted and so will these messages.
------------------------------
Subject: Why doesn't this newsfeeds entry do what I want?
"foo.com:alt,!alt.sex"
A newsfeeds entry is not a sys file (C News) entry. Please read
newsfeeds.5. You might also find the sys2nf program in the frontends
directory useful, as well as the inncheck Perl script that is found in
the samples directory. The INN Configuration FAQ has cook-book
examples of the steps required to install a NNTP feed, UUCP feed, and
NNTP via nntplink feed.
------------------------------
Subject: Why am I forwarding cancel messages for articles in comp.foo
when I explicitly have !comp.foo in the newsfeeds entry?
Control messages can be explicitly forwarded, so a control message to
comp.foo is forwarded to sites that recieve either comp.foo or control.
Please see the "Control Messages" section of innd.8. As that
documentation says, you probably want to put "!control" in the
subscription list for most of your newsfeeds.
------------------------------
Subject: Debugging someone that is feeding you.
David Myers <dem@meaddata.com> suggests that if a neighbor complains
that their feed to you doesn't work: (1) make sure they've read the man
pages, and (2) have them send a copy of their newsfeeds file.
Truly sage advice!
------------------------------
Subject: Feeds suddenly can't connect anymore!
Q: How come feeds tell me they can't connect to me any more?
A: When innd starts up it reads the hosts.nntp file and looks up the
IP addresses for all the entries mentioned there. The problem is that
this data is dynamic (sometimes people change IP addresses), and innd
never goes back to check. If your system stays up for days and one of
your feeds changes their IP address, innd will reject them. Rich plans
to handle this in INN1.5, but for now you might find it useful to do a
"ctlinnd reload hosts.nntp" out of cron every day or so or when you
notice there's a problem.
------------------------------
Subject: I'm getting groups sent to me that I don't want.
Tell the system administrator(s) of the machine(s) that feed news to
you to stop sending those groups. There is no other way to do it. (In
B or C News, the groups would end up in junk; at least with INN they
are not taking up space. You should compile with WANT_JUNK set to
DONT).
If the people that feed you use B news or C news, remember that they
don't use a "newsfeeds" file. They use a file called "sys" which has a
completely different format for specifying newsgroups.
------------------------------
Subject: When my feeder connects, I get articles but they don't take what's waiting for them.
I hate to say this, but this really shows that you haven't RTFMed very
much.
News is not automaticly bidirectional (it's like SMTP, not UUCP). If
you want to send things out you will have to make sure that you run
send-nntp or nntpsend from cron. nntpsend is easier and elsewhere in
this document there are cookbook examples of what to add every time you
set up a new feed.

Answer:
You forgot a zero in front of this number, for the C compiler to interpret it
as octal instead of decimal.
------------------------------
Subject: Why am I getting alt.sex.pictures even though I have
"ME:!alt.sex.pictures" in my newsfeeds file?
The active file is the definitive list of what newsgroups you receive.
INN's ME entry is different from C News and B News; please see
newsfeeds.5. If you do not want to receive alt.sex.pictures, ask the
system(s) that send you news not to send it to you. (You would have to do
that no matter what news system you are running.)
------------------------------
Subject: More about the "to.*" groups
(Thanks to jmalcolm@sura.net (Joseph Malcolm) for supplying
these answers.)
>1) Why did my local INN act on the sendsys posted to to.neighbor?
to.* groups aren't magic to INN. Your system received the message,
it acted on it.
>2) Why did my neighbor send the cmsg to all of his neighbors?
See 3.
>3) Is is related to having the "control" group in our newsgroups patterns?
Yes.
> The INN docs say you probably don't want to do this, but they don't say
> why.
Actually, they do. This is from innd(8):
Sites may explicitly have the ``control'' newsgroup in their
subscription list, although it is usually best to exclude
it. If a control message is posted to a group whose name
ends with the four characters ``.ctl'' then the suffix is
stripped off and what is left is used as the group name.
For example, a cancel message posted to ``news.admin.misc.ctl''
will be sent to all sites that subscribe to ``control'' or
``news.admin.misc''.
There is also a pointer to this in newsfeeds(5).
> But I still need it in my active file, right?
Yes.
------------------------------
Subject: What's a decent syslog.conf configuration?
The configuration will be different for each site, but here is what
Greg Earle recommends as the lines for the "news.*" related part.
Remember that most syslog's require tabs, not spaces.
Greg's canonical SunOS 4.1.x INN-related syslog.conf entries (which can
be merged into your current configuration):
#
# INN stuff
#
## Send critical messages to everyone who is logged in and to the console.
news.crit *
news.crit /dev/console
## Log news messages to separate files.
## Note that each level includes all of the above it.
## =()<news.crit @<_PATH_MOST_LOGS>@/news.crit>()=
news.crit /var/log/news/news.crit
## =()<news.err @<_PATH_MOST_LOGS>@/news.err>()=
news.err /var/log/news/news.err
## =()<news.notice @<_PATH_MOST_LOGS>@/news.notice>()=
news.notice /var/log/news/news.notice
------------------------------
Subject: INN batcher writing "#!rnews 0" separators
>Outgoing UUCP batches from here are going out with "#!rnews 0" at
>the head of each article.
Most common cause: your newsfeeds entry has "Wnm" not "Wnb".
Other reasons:
batchfiles have something other than a single space between article
filename and size
batchfiles lack size information (all the articles sizes will be read
from the batch file as zero)
------------------------------
Subject: Posting while throttled doesn't work
>I want to be able to allow my users to be able to post articles when
>innwatch has throttled the system when the spool disk is "full".
Cannot be done in 1.4.
At a minimum, in 1.5 nnrpd will spool the post for the user.
------------------------------
Subject: "innd: overview! spooling" and the file "overview!" in /usr/spool/news/out.going
> About once a month or so, I get the following warning messages:
>

This happens because innd is feeding info to overchan faster than
overchan can process it. The overflow is sent to the file
"overview!". This file can be deleted, as nnrpd will grab the missing
data out of the articles "manually". The slow-down won't be noticed.
However, you can "expireover -a" to "fill in the holes".
To prevent this in the future, you need to make overchan run faster.
This is easy to do. I found that moving the overview files into
/usr/spool/news/over.view made things fast enough that the problem went
away. Change "_PATH_OVERVIEWDIR" in config.data, recompile, and you're
done. (You will need to recompile any newsreaders that read via NFS or
off the local disk).
Why does that speed up overchan? overchan works by opening the proper
.overview file, appending 1 line to it, then closing the file. If you
have the .overview file in the same directory as 10000 articles then
opening the .overview file will take a huge amount of time. The open()
call literally searches though an average 5000 (half of 10000) file
names to find ".overview". If you move your .overview files so that
each one is in it's own directory, (say,
/usr/spool/news/over.view/{group}/{name}/.overview) then open() is
searching through 3 files ( ".", "..", and ".overview") to find 1
file. ( O(N/2) where N=10000 vs. N=3... and you thought those
freshman year CS classes would never be useful!)
There isn't much you can do to make the "append" and "close" steps much
faster, except maybe install a PrestoServe or similar write-cache, and
that won't help very much.
Profiling overchan (with PureSoft's Quantify product) found that the
open() (actually searching the directory to find the .overview file)
was around 80% of the execution time of overchan. That was reduced to
40% when I moved the .overview files to their own directory. With the
change, overview's profiling statistics are pretty flat. (which is
good).
DO run "expireover -a" to fix the problem.
DO NOT try feeding the "overview!" file to overchan manually.
(1) overchan doesn't do any locking and you'll have two overchan's
running at once.
(2) overchan only appends to the .overview files. If you've gotten
any articles since the "overview!" file was created (you will
have) then you'll be appending told old entries that are out of
order. Your ".overview" files must be in sorted order for the
other utilities to work right.
------------------------------
Subject: "newgroup" control messages aren't being executed
> "newgroup" control messages aren't be executed
The usual blame for this is _PATH_EGREP points to a grep that doesn't
understand regular expressions. For example, GNU grep only understands
regular expressions if it is called "egrep" (i.e. not "gnuegrep" or
"egnugrep").
Make sure you have a link or symlink between egnugrep and egrep. You
then need to modify config.data so that _PATH_EGREP is
/your/local/path/egrep and NOT /your/local/path/egnuegrep. Then
recompile and "make install" to have the new binaries and shell
scripts installed.

HOW DO I... (Big changes you can make to the system)
=====================================================================
------------------------------
Subject: How do I set up a delayed IHAVE/SENDME over NNTP?
Christophe Wolfhugel <Christophe.Wolfhugel@grasp.insa-lyon.fr> writes:
INN now allows to generate a timestamp entry in the batchfiles or to
the channels/exploders (Wt in newsfeeds) which can be used to allow (for
example) delayed ihave/sendme processing. INN's senders (like innxmit)
do not use that data yet.
Christophe.Wolfhugel@grasp.insa-lyon.fr has written a small patch for
nntplink 3.1.0 which supports this. The patch is available via
anonymous FTP on grasp.insa-lyon.fr in the file
"pub/unix/news/nntp/nntplink/delayed-1.0.pch".
The patch has been incorporated into nntplink 3.2, available from the
nntplink distribution site, shape.mps.ohio-state.edu in the file
/pub/nntplink/3.2pl1.tar.gz. nntplink 3.3 is due out soon.
HOW TO DO IT:
The syntax that you would use in your newsfeeds file would be:
site:*:Tf,Wnmt:
and run this command now and then:
nntplink -i batchfile -y 300 -b site news.site.fr
The delayed IHAVE/SENDME is expected to allow bandwidth savings in
situations where all sites use nntplink in following topology:
Your site -- 64k -----------+----------- Site 1
| |
| 2mb
| |
+------------ Site 2
Site 1 and 2 are in the same metropolitan area, you feed them both.
With the standard nntplink layout, you generally send all articles
twice, which is a waste even if you're at 2 Meg/s link and even if
Site 1 and 2 do nntplinks, you're faster.
The delayed link would be used between your site and Site 2. A 2 or
3 minute delay allows Site 1 to feed Site 2 before you, and in case
of a Site 1 outage the backup starts nearly immediately.
Reasonnable delays are still kept as You -> 1 -> 2 should take less
than one minute (or just 300 ms disk to disk if using nntplink -i ? :)).
Experiences seem to show that a 2 to 3 minutes delay is
a reasonable choice.

------------------------------
Subject: Can I use gzip with INN?
(this was written with the help of Michael Brouwer <michael@tar.wft.stack.urc.tue.nl>)
There are three things that can be effected by using gzip: Compression
of old logs, compressing batches to send out, and decompressing batches
that come in.
With INN 1.4 all you need to do is change two lines in config.data to
something like this:
COMPRESS /usr/local/bin/gzip
DOTZ .gz
If you rebuild INN with these options set, all logs will be gzipped, and rnews
will use gzip to decompress news.
gzip will automaticly and transparently decompress UNIX Compress, SCO
UNIX Compress (I'm told it's 99% compatible with UNIX Compress), Pack,
and gzip. Therefore, you can now receive batches compressed with any
of the above listed formats. Let's say your site is now has "a
universal decompresser".
It has been reported that if you hardlink gzip to be zcat, and make
sure that it is the zcat that INN uses, you can get the "universal
decompresser" without having to use gzip for your logs. (Though, gzip
for your logs is a big win, so why make trouble for yourself?)
`send-uucp' will still use compress for outgoing batches, so the sites
you feed won't suddenly start getting data they don't understand.
Before you can send gzipped batches, you should make sure that the
sites that you feed have made the above changes so that they have the
"universal decompresser" too.
Edit send-uucp to use gzip instead of compress for certain hosts (see
example of using compress -b12 for the host esac in send-uucp),
outgoing batches will be gzipped.
If you use sendbatch, you will have to edit the file so that COMPRESS
is set to "gzip" and COMPFLAGS is set to "-9vc".
------------------------------
Subject: What do I do if /var/spool/news is set up over many partitions?
First of all, you can do this by either mounting a filesystem at
/var/spool/news/comp (for example) or by mounting a filesystem anywhere
and making /var/spool/news/comp a symbolic link to the new partition.
Articles will be written as normal, but cross-posts have to be handled
specially now. Usually INN handles crossposts by writing the article
to the first newssgroup, and then creating hard links to all the other
places where the article should appear. Hard links do not take up
additional disk space (except making your directories longer). Hard
links also have the advantage that the file data doesn't get deleted
until the last hard link is gone (and they can be deleted in any
order). Therefore, you can expire each newsgroup at a different rate,
but the file data won't delete until it is expired from the last
newsgroup.
The problem is that two hard linked files must both be on the same
filesystem (partition).
When INN sees that it can not make a hard link (because an article is
cross-posted across two partitions) it will try to make a symbolic
link. If your system can not do symbolic links, set HAVE_SYMLINKS to
DONT in your config.data file. This will make INN write a second
(or third, etc.) copy of the file instead. (NOTE: INN 1.4 doesn't
make the extra files. This feature is planned for INN 1.5.)
Anyway, even though INN will automatically create symbolic links, you
have to give expire the "-l" flag so that it will know to modify its
behavior. Suppose that a message is posted to rec.photo and
alt.cameras and suppose that rec.photo expires more quickly then the
alt group. If this happens, then you will be left with a dangling
symlink. The -l flag prevents this from happening by not removing
the file from rec.photos until alt.cameras expire time permits it
from being deleted.
To inform expire that your spool is split across multiple partitions:
In news.daily, change:
EXPIREFLAGS="-v1"
to read
EXPIREFLAGS="-v1 -l"
In expirerm, change:
RMPROC="fastrm -e -u -s ${SPOOL}"

You also have to edit innwatch and innstat. After that, you're done!
If you ever need to run "makehistory" you should pay attention to this
caveat in makehistory(8):
Makehistory does not handle symbolic links. If the news
spool area is split across multiple partitions, the follow-
ing commands should probably be run before the database is
regenerated:
cd /usr/spool/news
find . -type l -print | xargs -t rm
However, if /var/spool/news/comp was a symlink to the partition
that comp is really on, you'll have to reinstall that link. You
have avoid this by changing the above commands to:
cd /usr/spool/news
find . -type l -print | grep '[0-9][0-9]*' | xargs -t rm

See doc/archive.8. You could also put "never:never:never" in your
expire.ctl file.

A cookbook newsfeeds entry:
# Feed all moderated source postings to an archiver
source-archive!:!*,*sources*,!*wanted*,!*.d\
:Tc,Nm,Wn:/usr/local/bin/archive -f -i /usr/spool/news.archive/INDEX

Subject: How do I set up inpaths with INN?
inpaths should work just fine with INN as it ships. However, you can
make it run faster by using the following shell script. Edit it to
your tastes. It replaces the long "(cd /var/spool/news ;
/usr/local/bin/gfind . -type f -print | /usr/lib/news/local/inpaths sdl
| /usr/ucb/mail admin,pathsurvey@decwrl.dec.com )" which people usually
use.
#!/bin/sh
. /home/news/innshellvars
cd ${SPOOL}
awk '(NR > 2){print $3}' < ${HISTORY} | tr . / | sort | \
inpaths `innconfval pathhost` | \
${MAILCMD} pathsurvey@decwrl.dec.com

BUGS IN 1.4
=====================================================================
UNOFFICIAL patches for INN 1.4 are available via anonymous FTP at
ftp://ftp.pop.psu.edu/pub/src/news/inn-patches/
The file ftp://ftp.pop.psu.edu/pub/src/news/inn-patches/README describes
each of the UNOFFICIAL patches.
The ones that are highly recommended are:
1.4-to-1.4sec -- Fixes the major security hole in INN.
1.4sec-to-1.4sec2 -- Fixes the remaining known security hole in INN.
select-loop-bug.patch -- Under some circumstances innd can lose track
of a file descriptor and end up sitting in a select() loop. If your
INN suddenly is using up tons of CPU time and not getting much done,
install this UNOFFICIAL patch. Some OSs are more susecptible to this
bug.

BUGS IN 1.3
=====================================================================
------------------------------
Subject: 7-bit encoded batches are not correctly processed. Why is this?
Chris Schmidt <cs@germany.eu.net> replies:
The decode program that comes with INN up to version 1.3 is broken.
Because of that the last article in a 7bit encoded batch will not
correctly be decoded (the last characters are screwed up). This is
fixed in INN 1.4.
------------------------------
Subject: NOV (overchan) doesn't work well.
Correct. The NOV support in 1.3 didn't have all the bugs worked out.
Don't use NOV under INN 1.3. Better yet, upgrade to 1.4sec and get all
the benefits!
=====================================================================
BUGS IN 1.2
(Hey, it's 1994! Upgrade already!)
=====================================================================
------------------------------
Subject: Why doesn't nntpget work?
The nntpget in INN 1.2 doesn't work. Period. Upgrade to the latest
version of INN.
