-<H2><A NAME="s1">1. Installation (Original version by Iain Philipps, G0RDI)</A></H2>
-
-<H2><A NAME="ss1.1">1.1 Introduction</A>
-</H2>
-
-<P>This section describes the installation of DX Spider v1.46 on a
-<A HREF="http://www.redhat.com">RedHat</A> Linux Distribution.
-Wherever possible I will try to include differences for other distributions.
-I do not intend to try and cover the installation of Linux or the setup
-of the AX25 utilities. If you need help on this then read Iains original
-installation guide that comes with the Spider distribution.
-<P>
-<P>I am assuming a general knowledge of Linux and its commands. You should
-know how to use <EM>tar</EM> and how to edit files using your favourite editor.
-<P>
-<P>The crucial ingredient for all of this is
-<A HREF="http://www.perl.org">Perl</A>. Earlier versions of
-Spider required perl 5.004, however it is now <I>STRONGLY</I> recommended
-that you use at least version 5.005_03 as this is the version being used
-in the development of Spider.
-<P>
-<P>In addition to the standard Red Hat distribution you will require the
-following modules from
-<A HREF="http://www.cpan.org/CPAN.html">http://www.cpan.org/CPAN.html</A> ...
-<P>
-<P>
-<UL>
-<LI> Data-Dumper-2.101.tar.gz</LI>
-<LI> TimeDate-1.10.tar.gz</LI>
-<LI> IO-1.20.tar.gz (for perl 5.00403 and lower)</LI>
-<LI> Net-Telnet-3.02.tar.gz</LI>
-<LI> Curses-1.05.tar.gz</LI>
-<LI> Time-HiRes-01.20.tar.gz
-</LI>
-</UL>
-<P>
-<P>
-<P><EM>Do</EM> get the latest versions of these packages and install them
-but use the above list as the earliest versions usable.
-<P>
-<H2><A NAME="ss1.2">1.2 Preparation</A>
-</H2>
-
-<P>I will assume that you have already downloaded the latest tarball of
-the DXSpider software and are ready to install it. I am assuming version
-1.46 for this section but of course you would use the latest version.
-<P>
-<P>Login as root and create a user to run the cluster under. <B><I>UNDER
-NO CIRCUMSTANCES USE ROOT AS THIS USER!</I></B>. I am going to use
-the name <EM>sysop</EM>. You can call it anything you wish. Depending
-on your security requirements you may wish to use an existing user,
-however this is your own choice.
-<P>
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-# adduser -m sysop
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<P>Now set a password for the user ...
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-# passwd sysop
-# New UNIX password:
-# Retype new UNIX password:
-passwd: all authentication tokens updated successfully
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<H2><A NAME="ss1.3">1.3 Installing the software</A>
-</H2>
-
-<P>Now to unpack the DX Spider distribution, set symbolic links and group
-permissions. Copy the tarball to /home/sysop and do the following.
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-# cd ~sysop
-# tar xvfz spider-1.46.tar.gz
-# ln -s ~sysop/spider /spider
-# groupadd -g 251 spider (or another number)
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>If you do not have the command <EM>groupadd</EM> available to you simply
-add a line in /etc/group by hand.
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-# vi /etc/group (or your favorite editor)
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>You also need to add some others to the group, including your own callsign
-(this will be used as an alias) and root. The finished line in /etc/group
-should look something like this
-<P><CODE>spider:x:251:sysop,g0vgs,root</CODE>
-<P>
-<P>The next step is to set the permissions on the Spider directory tree and files ....
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-# chown -R sysop.spider spider
-# find . -type d -exec chmod 2775 {} \;
-# find . -type f -exec chmod 775 {} \;
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<P>This last step allows various users of the group <EM>spider</EM> to have
-write access to all the directories. This is not really needed just yet
-but will be useful when web interfaces start to appear.
-<P>
-<P>Finally, you need to fix the permissions on the ax25_call and netrom_call
-programs. Check where they are with the <EM>locate</EM> command and alter
-the permissions with the <EM>chmod</EM> command like this ..
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-# chown root ax25_call netrom_call
-# chmod 4775 ax25_call netrom_call
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<H2><A NAME="ss1.4">1.4 Setting callsigns etc</A>
-</H2>
-
-<P>Now login to your machine as the user you created earlier. In my case that
-user is called <EM>sysop</EM>. Once logged in, issue the following commands ....
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-$ cd /spider
-$ mkdir local
-$ mkdir local_cmd
-$ cp perl/DXVars.pm.issue local/DXVars.pm
-$ cd local
-$ vi DXVars.pm (or your favourite editor)
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<P>Using the distributed DXVars.pm as a a template, set your cluster callsign,
-sysop callsign and other user info to suit your own environment. Note that
-this a perl file which will be parsed and executed as part of the cluster. If
-you get it wrong then perl will complain when you start the cluster process.
-It is important only to alter the text of any section. Some of the lines look
-a little odd. Take this line for example ....
-<P><CODE>$myemail = "ianmaude\@btinternet.com";</CODE>
-<P>
-<P>There appears to be an extra slash in there. However this has to be there
-for the file to work so leave it in.
-<P>
-<P><B>PLEASE USE CAPITAL LETTERS FOR CALLSIGNS</B>
-<P>
-<P>DON'T alter any file in /spider/perl, they are overwritten with every
-release. Any files or commands you place in /spider/local or /spider/local_cmd
-will automagically be used in preference to the ones in /spider/perl EVEN
-while the cluster is running!
-<P>
-<P>Save the new file and change directory to ../perl ....
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-$ cd ../perl
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<P>Now type the following command which creates the basic user file with you as
-the sysop.
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-$ ./create_sysop.pl
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<H2><A NAME="ss1.5">1.5 Starting up for the first time</A>
-</H2>
-
-<P>We can now bring spider up for the first time and see if all is well or not!
-It should look something like this ...
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-$ ./cluster.pl
-DXSpider DX Cluster Version 1.46

-loading prefixes ...
-loading band data ...
-loading user file system ...
-starting listener ...
-reading existing message headers
-reading cron jobs
-orft we jolly well go ...
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<P>If all is well then login on another term or console as <EM>sysop</EM> and
-cd to /spider/src. Now issue the following command ...
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-$ ./client
-</PRE>
-</CODE></BLOCKQUOTE>
-<P>
-<P>This should log you into the cluster as the sysop under the alias callsign we
-set earlier. In this case the callsign is G0VGS. The cluster callsign is set
-in the DXVars.pm file in /spider/local. In this case we will assume that this
-was set as GB7MBC. You should therefore see this when you login ....
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>

-</CODE></BLOCKQUOTE>
-<P>If you do, congratulations! If not, look over the instructions again, you
-have probably missed something out. You can shut spider down again with the
-command ....
-<P>
-<BLOCKQUOTE><CODE>
-<PRE>
-shutdown

-<P>
-<P>and both the cluster and the client should return to Linux prompts.
-<P>
-<H2><A NAME="ss1.6">1.6 The Client program</A>
-</H2>
-
-<P>In earlier versions of Spider, all the processes were Perl scripts. This
-was fine but with a lot of users your computer memory would soon be used up.
-To combat this a new client was written in "C". This client only works for
-<EM>incoming</EM> connects at the moment. Before you can use it though it
-has to be "made". CD to /spider/src and type <EM>make</EM>. You
-should see the output on your screen and hopefully now have a small C program
-called <EM>client</EM>. Leave it in this directory.
