+ 7. Security
+
+ 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.
+
+
+ 7.1. Registration
+
+ 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 set/register command,
+ like this ...
+
+
+
+ set/register g0vgs
+
+
+
+
+ The user g0vgs can now fully use the cluster. In order to enable
+ registration, you can issue the command ...
+
+
+
+ set/var $main::reqreg = 1
+
+
+
+
+ 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.
+
+
+ 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.
+
+
+ To unregister a user use unset/register and to show the list of
+ registered users, use the command show/register.
+
+
+ 7.2. Passwords
+
+ 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 set/password 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 ...
+
+
+
+ set/var $main::passwdreq = 1
+
+
+
+
+ at the cluster prompt. This can also be added to the
+ /spider/scripts/startup file as above to make the change permanent.
+
+
+ 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.
+
+
+ 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 ...
+
+
+
+ unset/password g0vgs
+ set/password g0vgs new_password
