Users of your ISP will probably want to read certain usenet newsgroups.
They generally have the expectation that access to news will be available
and that it will not cost anything - or at least it is bundled into the
costs of being a user on your system.
There are two options here for an ISP, either decide that you are not going to
provide a local news server, inform your users, and let them try to access
a news server elsewhere on the internet, or set up a local new server,
arrange to get a newfeed from your provider or elsewhere and make news
available from that server to your users.
So why would an ISP consider one or other option?
Using some other provider's news server seems a good idea, cheap and easy.
However, the problem is finding a provider who will make their server
available to your users. The cost and maintenance of a news server means
that there are fewer and fewer available for public access and very few
providers who will even allow reading access to the customers of downfeed
sites. You can try asking your service provider if they have a news server
that your users can access but expect the answer to be "No". Your provider
will probably want to send you a newsfeed to your news server.
The only problem with using that other person's news server is that your
users will have to use your link bandwidth just to read news or when they
arrange a newsfeed then there could be a fair proportion of your main link's
bandwidth used to transfer news directly to users. There is also a good chance
that a lot of these newsfeeds will cover the same newsgroups hence wasting
your precious bandwith moving multiple copies of the same news items.
The first place to look for a newsfeed should be your internet provider.
Normally this should be your source of a newsfeed as your provider will
want to minimise the volumes of usenet news using their link to the
internet.
If they do not have a news server (unlikely!) then they should be able to point
you to a news server that can provide you with a newsfeed.
All major providers in New Zealand maintain news servers. The best known
news service is provided by Netlink who took over the news service provided
by Victoria University (in associated with several other universities).
This was the first major news feed brought into New Zealand from 1989 and
has been the major source of newsfeeds since that time. Many ISPs still
subscribe to this service although in recent years alternatives for news feeds
have become available.
The Netlink
service is not free and Netlink have a monthly fee based on the size of the
newsfeed they provide to a customer. The Netlink news service has about
7000 newsgroups available although in the recent past they have decided not
to provide many binaries and sex related newsgroups. There is often no
public discussion about these matters, or discussion with Netlink news
customers, and final decisions over what newsgroups will be provided is left
to the news administrators at Netlink. (see http://www.netlink.co.nz)
The current pricing from Netlink is:
Large newsfeed NZ $300 per month
Medium newsfeed NZ $150 per month
Small newsfeed NZ $ 50 per month
There are other commercial news services available. Examples include Clarinet
and APC newsfeeds.
Clarinet is a newswire service
reporting on latest news items under various newsgroup headings. This
service can cost substantial US dollars where the charges are based on the
number of Clarinet newsgroups taken and the number of end users who are able
to access the news. (see http://www.clarinet.com)
The Association of Progressive Communications (APC) is an umbrella organistaion
that brings together many smaller news services that specialise in providing
newsgroups that cover many specific areas such as ecology, labour issues,
women's rights, housing, etc.. To subscribe to these newsgroups you need to
become a member of the APC or be associated with an ISP that is a member.
APC newsgroups are (were?) imported into New Zealand by the PlaNet New Zealand
groups of ISPs and made available to PlaNet members. It may be possible to
purchase these newsgroups from PlaNet. (see http://www.chch.planet.org.nz).
This will depend on the number of newsgroups you decide to subscribe to and
the data volumes in those newsgroups. The impact on your main internet
link will also depend on the bandwidth of that link.
Many ISPs start with a link of some type that has 48K or 64K bandwidth so
if a news server is to be provided for users then planning the workable
news volumes, newsgroups to subscribe to, and bandwidth requirements should
be considered.
Other news delivery mechanisms may be available to reduce the impact of a news feed at busy times. Your news provider may be prepared to only send news to your new server at offpeak times, usually during the early hours of the morning. Such a scheme may not be practical if your news server and link bandwidth has difficulty keeping up with your normal newsfeed, although for small to medium newsfeeds (hundreds to two thousand newsgroups) this should not be a problem.
There is no specific computer hardware that makes a usenet news server.
The requirements of a news server computer will vary depending on the
volume of news to be maintained, the size of the incoming newsfeed(s),
the number of outgoing newsfeeds and their sizes and the number of online news
reading sessions there could be.
A small news server will operate quite adeqately on a PC system. Even sharing
a PC that is used for other tasks - eg dns/mail server, terminal server, web
host etc.
The good news here is that good news management software is free. Several
packages are available for just about every operating system and instructions
for installing them are often straighforward although sometimes requiring a
fair amount of configuration.
One of the most popular packages is INN, this is available from several FTP
sites, the main site being
News delivery Methods
Fortunatly just about all of the popular web browsers now have a news reading
capability. Web users need only set up their news configuration to point to
a news server, get permission to use the server, and thats it.
Below are some details from recent news postings about several packages.
NNTPRelay [ NNTPRelay is a usenet news router, something like Cyclone or Diablo. It runs on Windows NT. ]SLURP
I use slurp (I got my copy from ftp.demon.co.uk/pub/news/slurp) to collect news
articles from a remote server and feed them to my INN server. To quote the
slurp man page:
Slurp is an advanced passive NNTP client for UNIX. It will connect to a
remote NNTP server and retrieve articles in a specified set of Usenet
newsgroups that have arrived after a particular time (typically the last
time it was invoked) for processing by your local news system.
NewsX
NewsX is an alternative to the "slurp" and "suck" already mentioned. It
came to be since the author found the other alternatives unsuitable for
various reasons.
NewsX was meant to be efficient, "polite" towards the news source, as
well as easy to set up. YMMV of course.
There is a home page for NewsX at:
http://home.sn.no/home/egilk/newsx.html
The source code can be found at sunsite.unc.edu and any of its mirrors.
Finally, beware that news "pulling" only is a suitable approach if you
intend carrying only a limited number of newsgroups on your local spool.
Since you have a dial-up connection, I assume that is your intention
anyway.
All of the large world distribution newsgroups are available in New Zealand and these really form the backbone of a news feed. These are imported by Netlink and distributed to subscribers who can connect to one of their news servers.
The major news groups hierarchies are:
Country specific newsgroups.
Apart from New Zealand newsgroups the other country specific news hierarchy
that is fully available in New Zealand is the Australian newsgroups under
under the aus hierarchy.
There are about 50 newgroups under aus and a fair number of posting originate
from NZ news sites.
This the nz newsgroup hierarchy, presently consisting of sixteen or so
separate newsgroups.
These are:
nz.archives - very low volume, (2 to 5 messages a week) postings mainly about
New Zealand ftp sites and newly available files
nz.arts - low volumes, (5 or less messages a day) arts related topics
nz.biz.misc - moderated, quite low volumes, miscellaneous business
topics/announcements newsgroup, see
nz.biz.misc FAQ
nz.comp - medium to high numbers of postings (20 to 30 a day), computing
related topics but does digress quite often.
nz.general - quite high volume, the 'catch all' newsgroup where anything and
everything is posted
nz.net.admin - very low volumes, occasional messages limited to sys admins and
those involved in NZ internet routing/administration
nz.net.announce - very low volumes, moderated.
nz.org.isocnz - few postings, newsgroup associated with the Internet Society.
nz.org.net-society - almost redundant newsgroups originally set up for the now
almost defunct network society.
nz.politics - medium volumes (10 to 20 messages per day), New Zealand politics.
nz.rec - low to medium volumes (5 to 10 messages per day), recreation.
nz.soc - low volumes, anything on social issues.
nz.soc.queer - newsgroup for the queer community, low to medium volumes.
nz.soc.green - green/ecology issues, most messages from Alan Marston of
Auckland PlaNet, low volumes.
nz.test - test newsgroup, low to medium usage, messages posted here get robot
replies from about six news servers around New Zealand.
nz.wanted - really wanted and buy/sell newsgroup, medium to high volumes.
nz.* Usenet Hierarchy FAQ
Many ISPs create their own set of newsgroups with distribution restricted to
their own users or downfeed sites. If you have a news system already set up
and operating then adding some local newsgroups is fairly easy and will
provide a local content to news.
The good thing about local newsgroups (for the ISP) is that the normal
procedures for creating a newsgroup do not apply since the newsgroup
distribution will be limited to the ISP.
Such local newsgroups often include:
A general chat group (general) which can cover any topic users want to discuss.
An announcements group which the ISP could use to provide service updates and
users can also use to post their own items of interest. If the ISP
announcements are regular or considered worthy of a separate newsgroup (perhaps
read only) then often a service newsgroup is created.
A comp group or perhaps new-user newsgroups where the messages tend to be
mainly computing related.
Maybe a test group where new users can test their news postings in a local
environment.
And other groups that may reflect the requirements of the ISP user base,
sometimes such groups are spawned from the general newsgroup where an area
of interest amongst users becomes evident.
