Having completed these general tasks, you can now turn to the really
interesting part of INN: its configuration files. All these files reside in
/etc/news. Some changes to configurations files were
introduced in Version 2, and it is Version 2 that we describe here. If you're
running an older version, you should find this chapter useful to guide you in
upgrading your configuration. During the next few sections, we will discuss
them one by one, building the Virtual Brewery's configuration as an example.
If you want to find out more about the features of individual configuration
files, you can also consult the manual pages; the INN distribution contains
individual manual pages for each of them.
INN's main configuration file is inn.conf. Among other
things, it determines the name by which your machine is known on Usenet.
Version 2 of INN allows a baffling number of parameters to be configured in
this file. Fortunately, most parameters have default values that are
reasonable for most sites. The inn.conf(5) file details
all of the parameters, and you should read it carefully if you experience any
problems.
The first line tells the programs rnews and
inews which host to contact when delivering articles.
This entry is absolutely crucial; to pass articles to
innd, they have to establish an NNTP connection with
the server.
The domain keyword should specify
the domain portion of the host's fully qualified domain name. A couple of
programs must look up your host's fully qualified domain name; if your
resolver library returns the unqualified hostname only, the name given in the
domain attribute is tacked onto it. It's not a problem to configure it either way, so it's best
to define domain.
The next line defines what hostname inews is going to use
when adding a From: line to articles posted by local users.
Most newsreaders use the From: field when composing a
reply mail message to the author of an article. If you omit this field, it
will default to your news host's fully qualifed domain name. This is ot
always the best choice. You might, for example, have news and mail handled
by two different hosts. In this case, you would supply the fully qualified
domain name of your mail host after the
fromhost statement.
The pathhost line defines the hostname
INN is to add to the Path: header field whenever it
receives an article. In most cases, you will want to use the fully
qualified domain name of your news server; you can then omit this field since
that is the default. Occasionally you may want to use a generic name, such as
news.vbrew.com, when serving a large
domain. Doing this allows you to move the news system easily to a different
host, should you choose to at some time.
The next line contains the organization
keyword. This statement allows you to configure what text
inews will put into the Organization:
line of articles posted by your local users. Formally, you would place a
description of your organization or your organization's name in full here.
Should you not wish to be so formal, it is fashionable for organizations with
a sense of humor to exhibit it here.
The organization keyword is mandatory
and specifies the pathname of the mail transport agent that will be used
for posting moderator messages. %s is replaced by the
moderator email address.
The moderatormailer entry defines a
default address used when a user tries to post to a moderated newsgroup. The
list of moderator addresses for each newsgroup is usually kept in a separate
file, but you will have a hard time keeping track of all of them. The
moderatormailer entry is therefore
consulted as a last resort; if it is defined, inews will
replace the %s string with the (slightly transformed)
newsgroup name and send the entire article to this address. For instance,
when posting to soc. feminism, the
article is mailed to
[email protected], given
the above configuration. At UUNET, there should be a mail alias installed for
each of these submissions addresses that automatically forwards all messages
to the appropriate moderator.
Finally, each of the remaining entries specifies the location of some component
file or executable belonging to INN. If you've installed INN from a package,
these paths should have been configured for you. If you're installing from
source, you'll need to ensure that they reflect where you've installed INN.
The news administrator on a system is able to control which newsgroups
users have access to. INN provides two configuration files that
allow the administrator to decide which newsgroups to support and provide
descriptions for them.
The active and newsgroups files
are used to store and describe the newsgroups hosted by this news server.
They list which newsgroups we are interested in receiving and serving
articles for, and administrative information about them. These files are
found in the /var/lib/news/ directory.
The active file determines which newsgroups this
server supports. Its syntax is straightforward. Each line in the
active file has four fields delimited by whitespace:
name himark lomark flags
The name field is the name of the
newsgroup. The himark field is the highest
number that has been used for an article in that newsgroup. The
lomark field is the lowest active number in
use in the newsgroup. To illustrate how this works, consider the
follow scenario. Imagine that we have a newly created newsgroup:
himark and
lowmark are both 0 because there are no
articles. If we post 5 articles, they will be numbered 1 through
5. himark will now equal 5, the highest
numbered article, and lowmark will equal 1,
the lowest active article. If article 5 is cancelled there will be no
change; himark will remain at 5 to ensure
that that article number is not reallocated and
lowmark will remain at 1, the lowest active
article. If we now cancel article 1, himark
will remain unchanged, but lowmark will now
equal 2, because 1 is no longer active. If we now post a new article,
it will be assigned article number 6, so
himark will now equal 6. Article 5 has been
in use, so we won't reassign it. lowmark
remains at 2. This mechanism allows us to easily allocate unique
article numbers for new articles and to calculate approximately how
many active articles there are in the group:
himark–lowmark.
The field may contain one of the following:
y
Posting directly to this news server is allowed.
n
Posting directly to this news server is not allowed. This prevents newsreaders
from posting directly to this news server. New articles may only be received
from other news servers.
m
The group is moderated. Any articles posted to this newsgroup are forwarded
to the newsgroup moderator for approval before they enter the newsgroup. Most
newsgroups are unmoderated.
j
Articles in this group are not kept, but only passed on. This causes the
news server to accept the article, but all it will do with it is pass it to
the “up-stream” news servers. It will not make the articles
available to newsreaders reading from this server.
x
Articles cannot be posted to this newsgroup. The only way that news articles
are delivered to this server is by feeding them from another news server.
Newsreaders may not directly write articles to this server.
=foo.bar
Articles are locally filed into the ``foo.bar'' group.
In our simple server configuration we'll carry a small number of
newsgroups, so our /var/lib/news/active file will
look like:
control 0000000000 0000000001 y
junk 0000000000 0000000001 y
rec.crafts.brewing 0000000000 0000000001 y
rec.crafts.brewing.ales 0000000000 0000000001 y
rec.crafts.brewing.badtaste 0000000000 0000000001 y
rec.crafts.brewing.brandy 0000000000 0000000001 y
rec.crafts.brewing.champagne 0000000000 0000000001 y
rec.crafts.brewing.private 0000000000 0000000001 y
The himark and lomark
numbers in this example are those you would use when creating new newsgroups.
The himark and lomark
numbers will look quite different for a newsgroup that has been active for
some time.
The newsgroups file is even simpler. It provides
one-line descriptions of newsgroups. Some newsreaders are
able to read and present this information to a user to help them decide
whether they want to subscribe.
The format of the newsgroups file is simply:
name description
The name field is the name of a newsgroup, and the <description is a single line description of that newsgroup.
We want to describe the newsgroups that our server supports, so we'll build
our newsgroups file as follows:
rec.crafts.brewing.ales Home brewing Ales and Lagers
rec.crafts.brewing.badtaste Home brewing foul tasting brews
rec.crafts.brewing.brandy Home brewing your own Brandy
rec.crafts.brewing.champagne Home brew your own Champagne
rec.crafts.brewing.private The Virtual Brewery home brewers group
INN provides the news administrator the ability to control which
newsgroups are forwarded on to other news servers and how they will be
forwarded. The most common method uses the NNTP protocol described
earlier, but INN also allows newsfeeds via other protocols, such as UUCP.
The newsfeeds file determines where news articles
will be sent. It normally resides in the /etc/news/
directory.
The format of the newsfeeds is a little complicated at
first. We'll describe the general layout here, and the
newsfeeds(5) manual page describes
what we leave out. The format is as follows:
# newsfeeds file format
site:pattern:flags:param
site2:pattern2\
:flags2:param2
Each news feed to a site is described by a single line, or may be
spread across multiple lines using the \ continuation character. The
: characters delimit the fields in each line. The # character at the
start of a line marks that line as a comment.
The site field names the site to which this feed
description relates. The sitename can be coded any way you like and
doesn't have to be the domain name of the site. The site name will be
used later and will refer to an entry in a table that supplies the
hostname to the innxmit program that transmits the
news articles by NNTP to the remote server. You may have multiple
entries for each site; each entry will be treated individually.
The pattern field specifies which news groups are
to be sent to this site. The default is to send all groups, so if that
is what you want, just make this field empty. This field is usually a
comma-delimited list of pattern-matching expressions. The * character
matches zero or more of any character, the . character has no special
significance, the ! character (if used at the start of an expression)
performs a logical NOT, and the @ character at the start of a
newsgroup name means “Do not forward any articles that are
posted or crossposted to this group.” The list is read and
parsed from left to right, so you should ensure that you place the
more specific rules first. The pattern:
would send all of the rec.crafts.brewing news heirarchy
except the rec.crafts.brewing.poison.
It would not feed any articles that were either posted or crossposted to the
rec.crafts.brewing.private newsgroup; these articles will
be trapped and available only to those people who use this server.
If you reversed the first two patterns, the first pattern would be overridden
by the second and you would end up feeding articles for the
rec.crafts.brewing.poison newsgroup. The same is true of
the first and last patterns; you must always place the more specific
patterns before any less specific patterns for them to take effect.
flags controls and places constraints on the feed
of news articles to this site. The flags field is a
comma delimited list can contain any of the items from the following list, delimited by commands:
<size
Article must be less then size bytes.
Aitems
Article checks. items can be one or more of
d (must have Distribution header) or
p (don't check for site in Path header).
Bhigh/low
Internal buffer size before writing to output.
H[count]
Article must have less then count hops; the default is 1.
Isize
Internal buffer size (for a file feed).
Mpattern
Only moderated groups that match the pattern.
Npattern
Only unmoderated groups that match the pattern.
Ssize
Start spooling if more than size bytes get queued.
Ttype
Feed types: f (file), m (funnel; the
param field names the entry that articles will be
funneled to), p (pipe to program), c
(send to stdin channel of the param field's
subprocess), and x (like c, but handles commands on stdin).
Witems
What to write: b (article bytesize), f
(full path), g (first newsgroup), m
(Message ID), n (relative path), s (site
that fed article), t (time received), *
(names of funnel feed-ins or all sites that get the article),
N (newsgroups header), D (distribution
header), H (all headers), O (overview
data), and R (replication data).
The param field has special coding that is dependent on
the type of feed. In the most common configuration it is where you specify
the name of the output file to which you will write the outgoing feed.
In other configurations you can leave it out. In yet other configurations
it takes on different meanings. If you want to do something unusual, the
newsfeeds(5) manual page will explain the use of the
param field in some detail.
There is a special site name that should be coded as ME
and should be the first entry in the file. This entry is used to control
the default settings for your news feeds. If the ME
entry has a distribution list associated with it, this list will
be prepended to each of the other site entries before they are sent.
This allows you to, for example, declare some
newsgroups to be automatically fed, or automatically blocked from
feeding, without having to repeat the pattern in each site entry.
We mentioned earlier that it was possible to use some special feeds to
generate thread data that makes the newsreader's job easier. We'll do this
by exploiting the overchan command that is part of the
INN distribution. To do this, we've created a special local feed called
overview that will pass the news articles to the
overchan command for processing into overview data.
Our news server will provide only one external news feed, which goes to
the Groucho Marx University, and they receive articles for
all newsgroups except the control and
junk newsgroups, the
rec.crafts.brewing.private newsgroup, which will be
kept locally, and the rec.crafts.brewing.poison
newsgroup, which we don't want people from our brewery seen posting to.
We'll use the nntpsend command to transport the news via
NNTP to the news.groucho.edu server. nntpsend requires us to use the “file”
delivery method and to write the article's pathname and article ID. Note
that we've set the param field to the name of the output
file. We'll talk a little more about the nntpsend
command in a moment. Our resulting newsfeed's configuration is:
# /etc/news/newsfeeds file for the Virtual Brewery
#
# Send all newsgroups except the control and junk ones by default
ME:!control,!junk::
#
# Generate overview data for any newsreaders to use.
overview::Tc,WO:/usr/lib/news/bin/overchan
#
# Feed the Groucho Marx University everything except our private newsgroup
# and any articles posted to the rec.crafts.brewing.poison newsgroup.
gmarxu:!rec.crafts.brewing.poison,@rec.crafts.brewing.private:\
Tf,Wnm:news.groucho.edu
#
The nntpsend program manages the transmission of
news articles using the NNTP protocol by calling the
innxmit command. We saw a simple use of the
nntpsend command earlier, but it too has a
configuration file that provides us with some flexibility in how we
configure our news feeds.
The nntpsend command expects to find batch files
for the sites it will feed. It expects those batch files to be named
/var/spool/news/out.going/sitename. innd
creates these batch files when acting on an entry in the
newsfeeds, which we saw in the previous
sections. We specified the sitename as the filename in the
param field, and that satisfies the
nntpsend command's input requirements.
The nntpsend command has a configuration file called
nntpsend.ctl that is usually stored in the
/etc/news/ directory.
The nntpsend.ctl file allows us to associate a fully
qualified domain name, some news feed size constraints, and a number of
transmission parameters with a news feed site name. The sitename is a means
of uniquely identifying a logical feed of articles.
The general format of the file is:
sitename:fqdn:max_size:[args]
The following list describes the elements of this format:
sitename
The sitename as supplied in the newsfeeds file
fqdn
The fully qualified domain name of the news server to which we will be feeding
the news articles
max_size
The maximum volume of news to feed in any single transfer
args
Additional arguments to pass to the innxmit command
Our sample configuration requires a very simple
nntpsend.ctl file. We have only one news feed. We'll
restrict the feed to a maximum of 2 MB of traffic and we'll pass an
argument to the innxmit that sets a 3-minute
(180 second) timeout. If we were a larger site and had many news feeds,
we'd simply create new entries for each new feed site that looked much
the same as this one:
Not so many years ago, it was common for organizations to provide public
access to their news servers. Today it is difficult to locate public news
servers; most organizations carefully control who has access to their
servers, typically restricting access to users supported on their network.
INN provides configuration files to control this access.
We mentioned in our introduction to INN that it achieves some of its
efficiency and size by separating the news feed mechanism from the
newsreading mechanism. The
/etc/news/incoming.conf file is where you specify
which hosts will be feeding you news using the NNTP protocol, as well
as where you define some parameters that control the way articles are
fed to you from these hosts. Any host not listed in this file that
connects to the news socket will not be handled by the
innd daemon; instead, it will be handled by the
nnrpd daemon.
The /etc/news/incoming.conf file syntax is
very simple, but it takes a moment to come to terms with. Three types of
valid entries are allowed: key/value pairs, which are how you specify
attributes and their values; peers, which is how you specify the name
of a host allowed to send articles to us using NNTP; and groups, a means
of applying key/value pairs to groups of peers. Key/value
pairs can have three different types of scope. Global pairs apply to
every peer defined in the file. Group pairs apply to all peers defined
within that group. Peer pairs apply only to that one peer. Specific
definitions override less specific ones: therefore, peer definitions
override group definitions, which in turn override global pairs.
Curly brace characters ({}) are used to delimit the
start and end of the group and peer
specifications. The # character marks the rest of the
line it appears on as a comment. Key/value pairs are separated by the
colon character and appear one to a line.
A number of different keys may be specified. The more common
and useful are:
hostname
This key specifies a comma-separated list of fully qualifed names or IP
addresses of the peers that we'll allow to send us articles. If this key is
not supplied, the hostname defaults to the label of the peer.
streaming
This key determines whether streaming commands are allowed from this host.
It is a Boolean value that defaults to true.
max-connections
This key specifies the maximum number of connections allowed from this group
or peer. A value of zero means unlimited (which can also be specified using
none).
password
This key allows you to specify the password that must be used by a peer if it
is to be allowed to transfer news. The default is to not require a password.
patterns
This key specifies the newsgroups that we accept from the associated peer.
This field is coded according to precisely the same rules as we used in our
newsfeeds file.
In our example we have only one host that we are expecting to feed us
news: our upstream news provider at Groucho Marx
University. We'll have no password, but we will ensure that we don't
accept any articles for our private newsgroup from outside. Our
hosts.nntp looks like:
# Virtual Brewery incoming.conf file.
# Global settings
streaming: true
max-connections: 5
# Allow NNTP posting from our local host.
peer ME {
hostname: "localhost, 127.0.0.1"
}
# Allow groucho to send us all newsgroup except our local ones.
peer groucho {
hostname: news.groucho.edu
patterns: !rec.crafts.brewing.private
}
We mentioned earlier that newsreaders, and in fact any host not listed
in the hosts.nntp, that connect to the INN news
server are handled by the nnrpd program. nnrpd uses the
/etc/news/nnrp.access file to determine who is
allowed to make use of the news server, and what permissions they
should have.
The nnrp.access file has a similar structure to the other
configuration files we've looked at. It comprises a set of patterns used to
match against the connecting host's domain name or IP address, and fields
that determine what access and permission it should be given. Each entry
should appear on a line by itself, and fields are separated by colons. The
last entry in this file that matches the connecting host will be the one
used, so again, you should put general patterns first and follow them with
more specific ones later in the file. The five fields of each entry in
the order they should appear are:
Hostname or IP address
This field conforms to wildmat(3) pattern-matching rules. It is a pattern that describes the connecting host's name or IP address.
Permissions
This field determines what permissions the matching host should be granted.
There are two permissons you may configure: R gives
read permissions, and P gives posting permissions.
Username
This field is optional and allows you to specify a username that an NNTP
client must log into the server before being allowed to post news
articles. This field may be left blank. No user authentication is required
to read articles.
Password
This field is optional and is the password accompanying the
username field. Leaving this field blank means that no
password is required to post articles.
Newsgroups
This field is a pattern specifying which newsgroups the client is allowed to
access. The pattern follows the same rules as those used in the
newsfeeds file. The default for this field is no
newsgroups, so you would normally have a pattern configured here.
In the virtual brewery example, we will allow any NNTP client in the Virtual
Brewery domain to both read and post to all newsgroups. We will allow any NNTP
client read-only access to all newsgroups except our private internal
newsgroup. Our nnrp.access file will look like this:
# Virtual Brewery - nnrp.access
# We will allow public reading of all newsgroups except our private one.
*:R:::*,!rec.crafts.brewing.private
# Any host with the Virtual Brewery domain may Read and Post to all
# newsgroups
*.vbrew.com:RP::*
When news articles are received by a news server, they are stored to
disk. News articles need to be available to users for some period of
time to be useful, so a large operating news server can consume lots
of disk space. To ensure that the disk space is used effectively, you
can opt to delete news articles automatically after a period of
time. This is called article expiration. Naturally,
INN provides a means of automatically expiring news articles.
The INN server uses a program called expire to delete
expired news articles. The expire program in turn uses a
file called /etc/news/expire.ctl to configure
the rules that govern article expiration.
The syntax of /etc/news/expire.ctl is fairly simple.
As with most configuration files, empty lines or lines beginning with the #
character are ignored. The general idea is that you specify
one rule per line. Each rule defines how article expiration will be performed
on newsgroups matching a supplied pattern. The rule syntax looks like this:
pattern:modflag:keep:default:purge
The following list describes the fields:
pattern
This field is a comma-delimited list of patterns matching names of
newsgroups. The wildmat (3) routine is used to
match these patterns. The last rule matching a newsgroup name is the
one that is applied, so if you want to specify wildcard (*) rules,
they should be listed first in this file.
modflag
This flag describes how this rule applies to moderated newsgroups. It can be
coded with an M to mean that this rule applies only to
moderated newsgroups, a U to mean that this rule applies
only to unmoderated newsgroups, or an A to mean that this
rule ignores the moderated status and applies to all groups.
keep
This field allows you to specify the minimum time an article with an
“Expires” header will be kept before it is expired. The units
are days, and are a floating point, so you may specify values like
7.5 for seven-and-a-half days. You may also specify
never if you wish articles to stay in a newsgroup forever.
default
This field is the most important. This field allows you to specify the
time an article without an Expires header will be
kept. Most articles won't have an Expires
header. This field is coded in the same way as the
keep field, with never meaning
that articles without Expires headers will never be
expired.
purge
This field allows you to specify the maximum time an article with an
Expires header will be kept before it is expired. The coding
of this field is the same as for the keep field.
Our requirements are simple. We will keep all articles in all newsgroups
for 14 days by default, and between 7 and 21 days for articles that have
an Expires header.
The rec.crafts.brewing.private newsgroup is our internal
newsgroup, so we'll make sure we don't expire any articles from it:
# expire.ctl file for the Virtual Brewery
# Expire all articles in 14 days by default, 7-21 days for those with
# Expires: headers
*:A:7:14:21
# This is a special internal newsgroup, which we will never expire.
rec.crafts.brewing.private:A:never:never:never
We will mention one special type of entry you may have in your
/etc/news/expires.ctl file.
You may have exactly one line that looks like this:
/remember/:days
This entry allows you to specify the minimum number of days that an article
will be remembered in the history file, irrespective of whether the article
itself has been expired or not. This might be useful if one of the sites that
is feeding you articles is infrequent and has a habit of sending you old
articles every now and again. Setting the /remember/
field helps to prevent the upstream server from sending you the article again,
even if it has already been expired from your server. If your server remembers
it has already received the article, it will reject attempts to resend it.
It is important to remember that this setting has no effect at all on article
expiration; it affects only the time that details of an article are kept in the history database.
Just as with C News, INN can automatically process control messages.
INN provides a powerful configuration mechanism to control what action will
occur for each of a variety of control messages, and an access control
mechanism to control who can initiate actions against which newsgroups.
The control.ctl file is fairly simple in structure.
The syntax rules for this file are much the same as for the other INN
configuration files. Lines beginning with #
are ignored, lines may be continued using /, and
fields are delimited by :.
When a control message is received, it is tested against each rule in turn.
The last rule in the file that matches the message is the rule that will be
used, so you should put any generic rules at the start of the file and
more specific rules at the end of the file. The general syntax of the file is:
message:from:newsgroups:action
The meanings of each of the fields are:
message
This is the name of the control message. Typical control messages are
described later.
from
This is a shell-style pattern matching the email address of the person
sending the message. The email address is converted to lowercase before comparison.
newsgroups
If the control message is newgroup or
rmgroup, this field is a shell-style pattern matching
the newsgroup created or removed.
action
This field specifies what action to take for any message matching the rule.
There are quite a number of actions we can take; they are
described in the next list.
The message field of each line can have one of the following values:
checkgroups
This message requests that news administrators resynchonrize their
active newsgroups database against the list of newsgroups supplied in
the control message.
newgroup
This message requests the creation of a new newsgroup. The body of the
control message should contain a short description of the purpose of
the newsgroup to be created.
rmgroup
requests that a newsgroup be removed.
sendsys
This message requests that the sys file of this
news server be transmitted by mail to the originator of the control
message. RFC-1036 states that it is a requirement of Usenet membership
that this information be publicly available because it is used to
keep the map of Usenet up to date.
version
This message requests that the hostname and version of news server
software be returned to the originator of the control message.
all
This is a special coding that will match any control message.
The message field may include the following actions:
doit
The requested command is performed. In many cases, a mail message will
be sent to the administrator to advise them that the action has taken place.
doit=file
This is the same as the doit action except
that a log message will be written to the file
log file. If the specified file is mail, the log
entry is sent by email. If the specified file is the null string, the
log message is written to /dev/null and is equivalent
to using the unqualified doit action. If the
file name begins with a / character, the name is
taken to be an absolute filename for the logfile; otherwise, the specified
name is translated to
/var/log/news/file.log.
doifarg
The requested command is performed if the command has an argument.
If the command has no argument, the control message is ignored.
drop
The requested command is ignored.
log
A log message is sent to the stderr output of the
innd process. This is normally directed out to the
/var/log/news/errlog file.
log=file
This is the same as a log action, except the
logfile is specified as per the rules given for the
doit=file action.
mail
An email message is sent to the news administrator containing the
requested command details. No other action takes place.
verify-*
If an action begins with the string “verify-”,
then the control message is authenticated using PGP (or
GPG).[1]
So that you can see what a control.ctl file would look
like in practice, here is a very short illustrative sample:
## Sample /etc/news/control.ctl
