As long as PPP is active, it will be possible to read news online. There are lots of available programs, two simple alternatives being rtin and trn.
To start reading news, the only thing required in terms of configuration in most cases is to set NNTPSERVER (usually once and for all in the file .profile):
To get the From-address correct in postings, some programs may require:
To be able to read news while offline and thus reduce phone bills and give greater flexibility, one must set up a local news-spool of one sort or the other. This requires some configuration, and there will also be a certain amount of disk space involved. After initial setup, things should run more or less by themselves, with only some attention needed from time to time.
Two different solutions will be described here.
The solution described here is based on the news-server C News and the NNTP protocol. C News was originally targeted towards another sort of configuration, but is flexible enough to handle our situation too. One might also use the more recent INN news server but it might require a bit more in terms of resources. Either way, be careful not to install both; they don't live together easily.
It is crucial that all maintenance of news is done while logged in as user
news, and that all configuration files is placed in
/usr/lib/news. One way of handling this is, while logged in as
root to write
su news; cd.
The most important files in the configuration are:
addgroup comp.os.linux.networking y.

sitein the Path: thread. In a setup as described here, using newsx, this name will never leave the machine, so you can set this to whatever you like as long as you are pretty sure it is unique. In this case
acme.xzto the Path, and that this is the only news source we have. The example given really tells that we will accept everything that arrives, and that we will only post news to
acme.xzthat it hasn't seen before, and is originally posted at our own site. In this simplified setup we assume that the all groups will come from a single source.
/allspecifies the distribution, and must be included. The letter
Fsays that (pointers to) outgoing news articles will be collected in a file.
C News needs a certain degree of daily maintenance, but this can be specified once and for all via the command
issued as user
news. A suggested setup follows; it can be tuned as required:
newsrun moves articles in and out (twice every hour), doexpire will delete articles as they get old (every night at 00:30), and the three last commands does various supervisory and error correcting tasks.
# maintain incoming and outgoing batches 10,40 * * * * /usr/lib/newsbin/input/newsrun # expire C News, once a day 30 0 * * * /usr/lib/newsbin/expire/doexpire # monitor and report if needed 00 2 * * sat /usr/lib/newsbin/maint/addmissing 40 3 * * * /usr/lib/newsbin/maint/newswatch 50 3 * * * /usr/lib/newsbin/maint/newsdaily
One should also ensure that things are cleaned up when starting the machine. As user root, add the following line to /etc/rc.d/rc.local:
News may be collected via the program NewsX, picking news from an NNTP-server The program can be found at:
su news -c /usr/lib/newsbin/maint/newsboot
NewsX is quite simple. Installation is a classic case of:
make su make install exit
With the setup outlined here, all you have to do is to create the groups you want to read using the addgroup command.
To fetch articles, user
news issues the following commands (assuming communication via PPP or similar is up):
newsrun newsx acme news.acme.xz newsrun
-d gives continuous printout to the screen. Refer to the NewsX documentation for further information.
NewsX will also take care of posting of outgoing news.
To control disposal of articles as they get old, a file
explist is required. The comments in this example should explain what we want to do:
# hold onto history lines 14 days, nobody gets >120 days /expired/ x 14 - /bounds/ x 0-1-120 - # retain these for 2 months comp.sources,comp.os.linux.all x 60 - # noise gets thrown away fast junk,control x 2 - # default: 14 days, no archive all x 14 -
ALT: In a small news-spool, one will usually not need the newsgroup
control. The traffic is huge compared to the possible usefulness. The main point is that articles will be canceled, and that groups may be created automatically. To ensure that control messages containing
newgroup not shall mess up things for us, a file called
newgroupperm specifies what we will allow:
In this example, all proper groups under comp.os.linux will be created (y), and the user
comp.os.linux email@example.com yv all any nq
newswill be notified (v). Everything else will be silently (q) ignored (n). The last line is sufficient if you want to create all groups manually.
ALT: An alternative to NewsX is suck.
A different solution altogether is to install the integrated package leafnode. This will handle all tasks required for a personal news spool, and is easy to configure. It is available via:
As for C News, all news maintenance really should be performed as user
The home directory for leafnode is in /usr/lib/leafnode. To install, write:
cd /usr/lib/leafnode tar -xzvf leafnode-0.8.tgz cd leafnode-0.8 make su make install
Note in the following that the prefix /usr/local/sbin should be replaced with /usr/sbin if you installed leafnode from a package.
While still being logged in as
root, change the line that controls NNTP in
Activate it by:
nntp stream tcp nowait news /usr/sbin/tcpd /usr/local/sbin/leafnode
killall -HUP inetd
Return to user
news by writing exit. In
/usr/lib/leafnode/config change the line that defines the NNTP server. In our case:
server = news.acme.xz
Leafnode will look after itself by adding the following command via
crontab -e as user
# expire Leafnode, once a day 0 4 * * * /usr/local/sbin/texpire
News exchange is also done as user
news by the following command (assuming PPP is up and running):
Users who wants to read news should then use the recipe in How do I set up an online news-reader?, except that they configure for the local machine, i.e:
That should be all there is to it. The first
fetch will transfer a list of available newsgroups. Leafnode will then monitor what groups the users are requesting, and adapt to this the next time it is activated.
Note that leafnode does not seems to work in cases where NNTP authorization is required. +.LP
ALT: An alternative to leafnode is nntpcache, available from:
ftp://ftp.suburbia.net/pub/nntpcache/nntpcache.tgz ALT: Another alternative is to use the newsreader
slrn together with the
slrn-pull package. The newsreader must be compiled with the
spool feature set.
