|
<P>From version 1.49 DXSpider has some additional security features. These
|
|
are not by any means meant to be exhaustive, however they do afford some
|
|
security against piracy. These two new features can be used independently
|
|
of each other or in concert to tighten the security.</P>

|
|
</H2>
|
|
|
|
<P>The basic principle of registration is simple. If a user is not registered
|
|
by the sysop, then they have read-only access to the cluster. The only
|
|
thing they can actually send is a talk or a message to the sysop. In
|
|
order for them to be able to spot, send announces or talks etc the sysop
|
|
must register them with the <EM>set/register</EM> command, like this ...</P>

<P>Any users that are not registered will now see the motd_nor file rather
|
|
than the motd file as discussed in the Information, files and useful
|
|
programs section.</P>
|
|
|
|
<P>Entering this line at the prompt will only last for the time the cluster
|
|
is running of course and would not be present on a restart. To make the
|
|
change permanent, add the above line to /spider/scripts/startup. To
|
|
read more on the startup file, see the section on Information, files
|
|
and useful programs.</P>
|
|
|
|
<P>To unregister a user use <EM>unset/register</EM> and to show the list
|
|
of registered users, use the command <EM>show/register</EM>.</P>

<H2><A NAME="ss9.2">9.2</A> <A HREF="adminmanual_en.html#toc9.2">Passwords</A>
|
|
</H2>
|
|
|
|
<P>At the moment, passwords only affect users who login to a DXSpider
|
|
cluster node via telnet. If a user requires a password, they can
|
|
either set it themselves or have the sysop enter it for them by using
|
|
the <EM>set/password</EM> command. Any users who already have passwords,
|
|
such as remote sysops, will be asked for their passwords automatically
|
|
by the cluster. Using passwords in this way means that the user has a
|
|
choice on whether to have a password or not. To force the use of
|
|
passwords at login, issue the command ...</P>

<P>at the cluster prompt. This can also be added to the /spider/scripts/startup

file as above to make the change permanent.</P>
|
|
|
|
<P>Of course, if you do this you will have to assign a password for each of
|
|
your users. If you were asking them to register, it is anticipated that
|
|
you would ask them to send you a message both to ask to be registered and
|
|
to give you the password they wish to use.</P>
|
|
|
|
<P>Should a user forget their password, it can be reset by the sysop by
|
|
first removing the existing password and then setting a new one like so ...</P>
