-<P>CVS stands for "Concurrent Versions System" and the CVS for DXSpider is held
-at
-<A HREF="http://www.sourceforge.net">Sourceforge</A>. This means
-that it is possible to update your DXSpider installation to the latest
-sources by using a few simple commands.
-<P>
-<P>THIS IS NOT FOR THE FAINT HEARTED!!! ONLY DO THIS IF YOU HAVE A TEST
-INSTALLATION OR ARE WILLING TO HAVE YOUR CLUSTER CRASH ON YOU!!!
-THIS MUST BE CONSIDERED AT LEAST BETA TESTING AND MAYBE EVEN ALPHA!!
-YOU HAVE BEEN WARNED!!!
-<P>
-<P>DID I MENTION..... ONLY DO THIS IF YOU ARE WILLING TO ACCEPT THE
-CONSEQUENCES!!!
-<P>
-<P>I am of course assuming that you have a machine with both DXSpider and
-Internet access running.
-<P>
-<P>BEFORE YOU EVEN CONSIDER STARTING WITH THIS MAKE A BACKUP OF YOUR
-ENTIRE SPIDER TREE!!
-<P>
-<P>Assuming you are connected to the Internet, you need to login to the
-CVS repository and then update your Spider source. There are several
-steps which are listed below ...
-<P>
-<P>First login as the user <EM>sysop</EM>. Next you need to connect to the CVS
-repository. You do this with the command below ...
-<P>
-<PRE>
-cvs -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider login
-</PRE>
-<P>You will get a password prompt. Simply hit return here and your machine should
-return to a normal linux prompt.
-<P>
-<P>What happens next depends on whether you have an existing installation that
-you want to update with the latest and greatest or whether you just want
-to see what is there and/or run it on a new machine for testing.
-<P>If you are installing Spider from CVS then change directory to /home/sysop
-<P>If you are wanting to update Spider then cd to /tmp
-<P>
-<P>The next step will create a brand new 'spider' directory in your current
-directory.
-<P>
-<PRE>
-cvs -z3 -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider co spider
-</PRE>
-<P>This command is all on one line.
-<P>
-<P>Hopefully your screen should show you downloading files. The -z3 simply compresses
-the download to improve speed.
-When this has finished, you will have exactly the same as if you had untarred a full
-tarball PLUS some extra directories and files that CVS needs to do the magic that
-it does.
-<P>
-<P>Now if you are doing a new installation, that's it. Carry on as if you have
-just downloaded and untarred the lastest tarball.
-<P>
-<P>If you want to upgrade your current installation then do this ...
+<P>In the spider tree will be a directory <EM>spider-web</EM>. This is a
+neat little java web applet that can be run from a website. The applet
+must run on the same machine as the cluster. The included README file is
+shown below.</P>
+
+<P>I should comment here that the applet is precompiled, that is, ready to go.
+It was compiled using JDK1.3.1. If your version is earlier than this then it
+may not work. Should that be the case you need to recompile or update your
+JDK. To recompile do the following ...</P>
<P>
<BLOCKQUOTE><CODE>
<PRE>
-tar cvfz /tmp/s.tgz spider
-cd /
-tar xvfzp /tmp/s.tgz
+cd /spider/spider-web
+rm *.class
+/usr/bin/javac spiderclient.java
</PRE>
</CODE></BLOCKQUOTE>
-<P>This is assuming you downloaded to the /tmp directory of course.
-<P>
-<P>NOTE: the 'p' on the end of the 'xvfz' is IMPORTANT! It keeps the permissions
-correct. YOU WERE LOGGED IN AS THE USER SYSOP WEREN'T YOU?????
-<P>Remember to recompile the C client (cd /spider/src; make)
-<P>
-<P>At this point the files have been upgraded. You can (usually) restart the cluster
-in your own time. However, if you attempt to use any new commands or features
-expect it to be fatal! At least your cluster will have been restarted then so it
-will be too late to worry about it!
-<P>
-<P>Now the magic part! From now on when you want to update, simply connect to the
-Internet and then, as the user <EM>sysop</EM> ...
+</P>
+
+<P>I have used /usr/bin/javac as an example, your path to javac may be different.</P>

-cd /spider
-cvs -z3 update -d
+Spider-WEB v0.6b
+
+Completely based on a clx web client written in Java by dl6dbh
+(ftp://clx.muc.de/pub/clx/clx-java_10130001.tgz)
+
+The webserver has to run on the same machine as your DxSpider software!
+
+It is assumed that you have Java installed. You need JDK1.3.1 at least.
+
+Installation instructions (Performed as root):
+
+Put all the files in the spider-web directory into a newly created directory
+under the DocumentRoot of your websever for instance 'client'. In my case
+this is: /home/httpd/html/client/ although ymmv. For Suse the correct
+path should be /usr/local/httpd/htdocs/client/ for example.
+
+Move spider.cgi to the cgi-bin directory of your webserver, in my case that is
+/home/httpd/cgi-bin/ although ymmv. For Suse the correct path should be
+/usr/local/httpd/cgi-bin/ for example.
+
+Change the permissions of the files to ensure they are correct, obviously you
+will need to use the correct path the the files according to your system:
+
+chmod 755 /home/httpd/html/cgi-bin/spider.cgi
+chmod -R 755 /home/httpd/html/client/
+
+By default the spider.cgi script should pick up your hostname (As long as this
+is set correctly). If it does not or your hostname differs from the name that
+you attach to the public address that you are using, then edit spider.cgi :
+
+# Uncomment and set the hostname manually here if the above fails.
+# $HOSTNAME = "gb7mbc.spoo.org" ;
+$PORT = "8000" ;
+
+'HOSTNAME' is the hostname of your cluster.
+
+'PORT' is the portnumber that you use to connect to your DxSpider via
+telnet (see Listeners.pm)
+
+NOTE: If you can start the console but cannot connect to the cluster from it,
+then it is possible that the machine you are on cannot resolve the hostname of
+your cluster machine. If this is the case, you need to set your hostname
+manually as above.
+
+You also need to set the $NODECALL variable. This prints the name of your
+choosing (probably your cluster callsign) on the html page.
+
+You now can connect to Spider-Web via http://yourserver/cgi-bin/spider.cgi

-<P>and your files will be updated. As above, remember to recompile the "C" client
-if it has been updated (CVS will tell you) and restart if any of the perl scripts
-have been altered or added, again, CVS will tell you.
-<P>
-<P>You will find any changes documented in the /spider/Changes file.
