<abstract>
A reference for SysOps of the DXSpider DXCluster program.
The crucial ingredient for all of this is
<htmlurl url="http://www.perl.org" name="Perl">. Earlier versions of
Spider required perl 5.004, however it is now <it>STRONGLY</it> recommended
-that you use at least version 5.005_03 as this is the version being used
+that you use at least version 5.6.1 as this is the version being used
in the development of Spider.

+On most modern distributions most (if not all) the modules you will need are either included or
+can be loaded automatically. Please consult your distro's instructions for loading new programs
+and look for modules that usually start with the string "perl-". For instance:-
+
+<itemize>
+<item>Mandrake: urpmi perl-TimeDate perl-Digest-SHA1 perl-Curses perl-Net-Telnet
+<item>Redhat/Fedora: up2date perl-TimeDate perl-Digest-SHA1 perl-Curses perl-Net-Telnet
+<item>SuSE: use yast
+<item>Debian: use apt-get
+</itemize>
+
+<p>
+Some distros are now packaging perl-DB_File separately as well, so you may have to add that to the list
+above.
+
<P>
Copy the CPAN modules listed above to a convenient place on your computer. One good
place would be /usr/local/packages, and the instructions which follow will assume that
Log in as 'root', and make sure you're at '/root' before you continue. Here are exactly the commands you must issue next: -
<verb>
-# tar xvfz /usr/local/packages/Data-Dumper-2.101.tar.gz
-# cd Data-Dumper-2.101
+# tar xvfz /usr/local/packages/TimeDate-2.27.tar.gz
+# cd TimeDate-2.27
# perl Makefile.PL
# make test
# make install
# cd ..
#
-# tar xvfz /usr/local/packages/TimeDate-1.10.tar.gz
-# cd TimeDate-1.10
+# tar xvfz /usr/local/packages/Net-Telnet-3.03.tar.gz

+# cd Digest-SHA1-2.01
# perl Makefile.PL
# make test
# make install
# cd ..
+</verb>
+
+<p>
+Only if you need to do these because your perl is old:-
+
+<verb>
#
-# tar xvfz /usr/local/packages/Time-HiRes-01.20.tar.gz
-# cd Time-HiRes-01.20
+# tar xvfz /usr/local/packages/IO-1.20.tar.gz

This is dealt with in the previous section
-<sect1>Allowing telnet connects from users
+<sect1>Setting up telnet connects (from 1.47 onwards)
+
+<P>
+>From version 1.47 you can choose to allow the perl cluster.pl program to
+allow connections directly (i.e. not via the <tt>/spider/src/client</tt>
+interface program). If you are using Windows then this is the only method
+available of allowing incoming telnet connections.
+
+<P>
+to make the change happen...
+
+<P>
+Having done that, you need to copy the file
+<em>/spider/perl/Listeners.pm</em> to <em>/spider/local</em> and
+then edit it. You will need to uncomment the line containing &dquot;0.0.0.0&dquot;
+and select the correct port to listen on.
+
+It comes out of the box looking something like:-
+
+<tscreen><verb>
+@listen = (
+# ["0.0.0.0", 7300],
+);
+</verb></tscreen>
+
+Change it so that it looks like this:-
+
+<tscreen><verb>
+@listen = (
+ ["0.0.0.0", 7300],
+);
+</verb></tscreen>
+
+<p>
+Later versions have more comments in the Listeners.pm file that
+are designed to help you remove the correct '#' character.
+
+<P>
+As standard, the listener will listen on all interfaces simultaneously.
+If you require more control than this, you can specify each interface
+individually:-
+
+<tscreen><verb>
+@listen = (
+ ["gb7baa.dxcluster.net", 7300],
+ ["44.131.16.2", 6300],
+);
+</verb></tscreen>
+
+<P>
+This will only be successful if the IP addresses on each interface are static.
+If you are using some kind of dynamic IP addressing then the 'default' method
+is the only one that will work.
+
+<P>
+Restart the cluster.pl program to enable the listener.
+
+<P>
+One important difference with the internal listener is that no echoing
+is done by the cluster program. Users will need to set 'local-echo' on in
+their telnet clients if it isn't set automatically (as per the standards).
+Needless to say this will probably only apply to Windows users.
+
+<sect1>Allowing telnet connects from users (before version 1.47 or for special purposes)
<P>
>From version 1.47 there is a new (more efficient) way of doing this
-(see next section) but, if you prefer, the method of doing it described
+(see previous section) but, if you prefer, the method of doing it described

You should now get the login prompt and be able to login as before.
