<H2><A NAME="Setting">Setting</A> up users and user groups</H2>
<P>
<FONT SIZE=3>You enter all user names (<B>even your name if you
are a single user</B>). To do this, double-click on the !Connect icon in the Internet directory, to load !Connect. From !Connect's icon bar icon, choose the Menu option <B>Admin/Users...</B>. This will display the <B>Users</B> dialogue box:<BR>
</FONT>
<P ALIGN="CENTER">
<IMG SRC="Diagrams/Img00021" WIDTH="411" HEIGHT="187><BR>
<P>
<FONT SIZE=3>Enter each 'Username' in the <B>User</B> field. Usernames can be up to 19 characters long, passwords
10 characters. They should use only alpha and numeric characters.
They are not case-sensitive (i.e., <B>t</B> works the same as
<B>T</B>). For maximum security passwords should not be words
found in the dictionary, and should include numbers as well as
letters.</FONT>
<P>
<FONT SIZE=3>If you are use POP3 mail delivery, you must create
a user with the same name as your POP3 Username, as it is to this
user that mail will be addressed.</FONT>
<P>
<FONT SIZE=3>Users can change their passwords from the !Mail icon
bar menu unless Lock password... is set. You may want to set this for shared accounts, where you don't want one user changing the password unilaterally.
<P>
The <B>System user</B> option is for future expansion.</FONT>
<P>
<FONT SIZE=3>Network users can save time entering a large number
of users by first listing their names in a plain text or CSV (Comma
Separated Value) file, then saving the text file into the Users
dialogue box. You may already have such a list of users on your
school administration system. Even DOS programs can often provide
plain ASCII CSV data files, and your Acorn computer can read DOS
floppy discs.</FONT>
<P>
<FONT SIZE=3>The format of the text file to add users can be any
one of the following (to remove users, prefix the line with a
minus instead of a plus):</FONT>
<P>
<TT><FONT SIZE=3 FACE="Courier">+emailname password group Yes/No
(Web) Yes/No (lockpassword) Yes/No (systemuser) fullname</FONT></TT>
<P>
<TT><FONT SIZE=3 FACE="Courier">+emailname,password,group,Yes/No,Yes/No,Yes/No,fullname</FONT></TT>
<P>
<TT><FONT SIZE=3 FACE="Courier">+&quot;emailname&quot;,&quot;password&quot;,&quot;group&quot;,&quot;Yes/No&quot;,&quot;Yes/No&quot;,&quot;Yes/No&quot;,&quot;fullname&quot;</FONT></TT>
<P>
<FONT SIZE=3>For example:</FONT>
<P>
<FONT SIZE=3>Enter users to be included in the group 'all':</FONT>
<P>
<TT><FONT SIZE=3 FACE="Courier">+rjohnson xroads all yes no no
Robert Johnson</FONT></TT>
<P>
<TT><FONT SIZE=3 FACE="Courier">+cberry jonnybg00d all yes no
no Charles Berry etc</FONT></TT>
<P>
<FONT SIZE=3>or</FONT>
<P>
<TT><FONT SIZE=3 FACE="Courier">+jpage,5tairway,all,yes,no,no,James
Page etc</FONT></TT>
<P>
<FONT SIZE=3>Remove a user from the group 'Usixth':<BR>
</FONT>
<P>
<TT><FONT SIZE=3 FACE="Courier">-&quot;efitzgerald&quot;,&quot;manhattan&quot;,&quot;USixth&quot;,&quot;yes&quot;,&quot;no&quot;,&quot;no&quot;,&quot;Ella
Fitzgerald&quot;</FONT></TT>
<H3>User groups</H3>
<P>
<FONT SIZE=3>In network use it is important to set up user groups,
as it is by this mechanism that you can control access to particular
newsgroups and email to and from specific locations. For single-user
application, however, it is not necessary to set these up.</FONT>
<H2><A NAME="Managing">Managing</A> newsgroups</H2>
<P>
<FONT SIZE=3>Whenever !Connect connects with the service provider,
articles from all newsgroups allowed are downloaded. If many newsgroups
are allowed, this can involve a massive amount of data. <B>It
is therefore important to ensure that you only allow newsgroups
in which you have a specific interest, and keep their numbers
to a minimum. Otherwise, downloading could take many hours!</B></FONT>
<P>
<FONT SIZE=3>Similarly, just the <B>titles</B> of all the newsgroups
available make up a large file, so only the most commonly-used
are included on the Acorn Internet software disc. These are listed
in the file !Connect.Newsgroups. A very large Newsgroups file
will consume a significant amount of RAM on your machine, so you
may wish to remove unwanted lines inside the file (load it into
Edit to do so). </FONT>
<P>
<FONT SIZE=3>If you do want the complete up-to-date list, choose
<B>Update newsgroup list when next connected</B> (see <A HREF="#disallowing" >Allowing and disallowing newsgroups</A>),
but you do not have to leave this option switched on, as it will
run up your connection charges unnecessarily.</FONT>
<H3><A NAME="_Ref400436267">Allowing and</A> <A NAME="disallowing">disallowing</A>
newsgroups</H3>
<P>
<FONT SIZE=3>To allow or disallow a newsgroup, choose <B>Admin/Newsgroups...</B>.
The following dialogue box will be displayed:</FONT>
<P><BR>
<TABLE WIDTH=100%>
<TR><TD WIDTH=440><B><IMG SRC="Diagrams/Img00028" WIDTH="427" HEIGHT="236"></B></TD>
<TD><FONT SIZE=1><UL>
<LI>Choose the <B>group</B> (single-users leave at <B>All</B>)</FONT>
<LI>
<FONT SIZE=1>Type in or choose via the list below the <B>newsgroup</B> to be allowed or disallowed. You can use wildcards (see below)</FONT>
<LI>
<FONT SIZE=1>Choose to download the complete <B>list</B> of newsgroups when connected (lengthy)</FONT>
<LI>
<FONT SIZE=1>Click on <B>Allow, Disallow</B> or <B>Remove</B>. Use the Adjust mouse button when dealing with more than one newsgroup. <B>Remove</B> will remove all access to a newsgroup. <B>Disallow</B> will disallow access to that user group only.</FONT></UL>
<P>
<FONT SIZE=1>In the list of newsgroups below, sub-groups will cascade when parent groups are chosen, making selection quicker</FONT>
</TD></TR>
</TABLE>
<P>
<FONT SIZE=3>(The newsgroups themselves will only be loaded once
you have connected to your service provider.)</FONT>
<P>
<FONT SIZE=3>The menu which lists available newsgroups has a writable
line at the top where you can enter the name of the newsgroup
in which you are interested, or you can click on the newsgroup
listed.</FONT>
<P>
<FONT SIZE=3>If the server does not find the file `Newsgroups'
inside the '!Connect' application, it will load a full list from
the service provider.</FONT>
<H4><FONT SIZE=3>Using wildcards</FONT></H4>
<P>
<FONT SIZE=3>You can speed up the process of allowing and disallowing
newsgroups by using wildcards when you specify newsgroups. This
is useful because there are so many of them. Wildcards are (usually)
single characters which stand in for several characters of a similar
type. Two wildcards are available for describing newsgroups:</FONT> 
<UL>
<LI>* meaning any number and type of letter</FONT> 
<LI><TT><I> <FONT SIZE=3 FACE="Courier"> &lt;string&gt;</FONT> </I></TT> <FONT SIZE=3>
 where </FONT>  <TT><I> <FONT SIZE=3 FACE="Courier"> string</FONT>  </I></TT> <FONT SIZE=3>
 is any sequence of characters.</FONT> 
</UL>
<P>
 <FONT SIZE=3>So, </FONT> <TT><FONT SIZE=3 FACE="Courier"> comp.* </FONT> </TT> <FONT SIZE=3>
 would mean all the newsgroups which start </FONT> <TT> <FONT SIZE=3 FACE="Courier"> comp. </FONT> </TT> <FONT SIZE=3>,
 such as </FONT> <TT> <FONT SIZE=3 FACE="Courier"> comp.sys.acorn </FONT> </TT> <FONT SIZE=3>
 for example.</FONT> 
<P>
<TT> <FONT SIZE=3 FACE="Courier"> &lt;cultur&gt; </FONT> </TT><FONT SIZE=3>
 would signify all newsgroups with <TT> cultur </TT>
 anywhere in their title (such as culture and cultural).</FONT> 
<P>
<TT> <FONT SIZE=3 FACE="Courier"> &lt;politic&gt; </FONT> </TT> <FONT SIZE=3>
 would cover all newsgroups with <TT> politic </TT>
 anywhere in their title (such as politics, politicians and political).</FONT> 
<P>
<TT><FONT SIZE=3 FACE="Courier"> &lt;sex&gt; </FONT> </TT> <FONT SIZE=3>
 could be used to disallow all newsgroups with </FONT> <TT> <FONT SIZE=3 FACE="Courier"> sex </FONT> </TT> <FONT SIZE=3>
 anywhere in their title (including, for example, </FONT> <TT> <FONT SIZE=3 FACE="Courier"> Essex </FONT> </TT> <FONT SIZE=3>).</FONT> 
<H3><FONT SIZE=3>Newsgroup expiry times</FONT></H3>
<P>
<FONT SIZE=3>You can configure how long news articles remain accessible.
</FONT>
<P>
<FONT SIZE=3>Obviously, very old articles lose their topicality
and need to be deleted to make room for new ones. The default
life for a news article is seven days, but this may be changed
using <B>Admin/Expiry times/Newsgroups</B>.</FONT>
<P>
<FONT SIZE=3>Newsgroups with a high volume of traffic might be
set to keep their articles a shorter time than those with a low
volume, for example, to avoid the hard disc filling up too quickly.</FONT>

</TD></TR>
</TABLE>
<P><H2><A NAME="Mail">Mail</A> statistics</H2>
<P>
<FONT SIZE=3>A number of mail reports are available to the network
manager to help judge the performance of the system, how much
it is being used, and by whom. These reports are available from
the menu option Reports/Statistics, and are largely self-explanatory:</FONT>
<UL>
<LI><B><FONT SIZE=3>Allowed groups</FONT></B> <FONT SIZE=3> (allowed
newsgroups, by user, group and total). <B>Subscribed groups</B>
in the case of the single-user version of Acorn Internet software.</FONT>
<LI><B><FONT SIZE=3>Connect times</FONT></B> <FONT SIZE=3> (a list
of recent connection times)</FONT>
<LI><B><FONT SIZE=3>Disc usage</FONT></B> <FONT SIZE=3> (by user,
group and total)</FONT>
<LI><B><FONT SIZE=3>Censorship</FONT></B> <FONT SIZE=3> (a list
of disallowed addresses by user group).</FONT>
</UL>
<P>
<FONT SIZE=3>Each of these subjects leads to a Save dialogue box
- drag the textfile icon to !Edit to view the report, or to a
printer to print it out.</FONT>
<H2><A NAME="Displaying">Displaying</A> the server log</H2>
<P>
<FONT SIZE=3>You can display the Acorn Internet software server
communications log by choosing Show log from the Connect main
menu:<BR>
</FONT>
<P ALIGN="CENTEr"> 
<IMG SRC="Diagrams/Img00031" WIDTH="389" HEIGHT="68"><BR>
<P>
<FONT SIZE=3>The server log tracks the activities of the server
as they occur. This is useful for network management and tracing
problems.</FONT>
<H3>Saving the server log</H3>
<P>
<FONT SIZE=3>When you quit Connect, the current log is saved to
disc as the file Log inside !Connect.</FONT>
<H3>Log file messages</H3>
<P>
<FONT SIZE=3>Do not be alarmed if some of the text in the log
appears truncated- &quot;Got rotocol&quot; for example. This is
often because service providers use a mixture of upper and lower
case letters, the first letter being ignored when matching text
strings.</FONT>
<P>
<FONT SIZE=3>RMEnsure messages are displayed complete, together
with their associated error messages, but this does not necessarily
mean than an error has occurred.</FONT>
<H2><A NAME="Finger">Finger</A></H2>

<FONT SIZE=3>Finger, available from the Connect main menu, is
a convenient way of interrogating a service provider. <BR>

<H2><A NAME="Saving">Saving</A> space</H2>
<P>
<FONT SIZE=3>A list of the more commonly-accessed newsgroups is
supplied. It is held in the file !Connect.Newsgroups. If you want
a complete list, simply delete this file, and !Connect will load
another from the service provider next time you connect. However,
this list is large, (approximately 200K) and you can save space
if you subsequently delete entries in which you are unlikely to
have any interest. Deletion can be performed by dragging the file
to !Edit, manually deleting unwanted sections, and then saving
the file again.</FONT>
