21 <P>This section describes the installation of DX Spider v1.50 on a
22 <A HREF="http://www.redhat.com">RedHat</A> Linux Distribution.
23 Wherever possible I will try to include differences for other distributions. </P>
25 <P>I am assuming a general knowledge of Linux and its commands. You should
26 know how to use <EM>tar</EM> and how to edit files using your favourite editor.</P>
28 <P>The crucial ingredient for all of this is
29 <A HREF="http://www.perl.org">Perl</A>. Earlier versions of
30 Spider required perl 5.004, however it is now <I>STRONGLY</I> recommended
31 that you use at least version 5.6.1 as this is the version being used
32 in the development of Spider.</P>
34 <P>In addition to the standard Red Hat distribution you will require the
35 following modules from
36 <A HREF="http://www.cpan.org/modules/by-module/">http://www.cpan.org/modules/by-module/</A> , please note however that with later versions of perl, some of these
37 modules may be included with the distribution. Get the modules anyway and try
38 to install as below. If they complain, they are probably already a part of your
39 perl distribution.</P>
44 <A HREF="http://www.cpan.org/modules/by-module/Data/Data-Dumper-2.101.tar.gz">Data-Dumper-2.101.tar.gz</A> <EM> this is included in perl 5.6.1 and above </EM></LI>
46 <A HREF="http://www.cpan.org/modules/by-module/Date/TimeDate-1.10.tar.gz">TimeDate-1.10.tar.gz</A></LI>
48 <A HREF="http://www.cpan.org/modules/by-module/IO/IO-1.20.tar.gz">IO-1.20.tar.gz</A> (<EM>for perl 5.00403 and lower</EM>)</LI>
50 <A HREF="http://www.cpan.org/modules/by-module/Net/Net-Telnet-3.03.tar.gz">Net-Telnet-3.03.tar.gz</A></LI>
52 <A HREF="http://www.cpan.org/modules/by-module/Curses/Curses-1.06.tar.gz">Curses-1.06.tar.gz</A></LI>
54 <A HREF="http://www.cpan.org/modules/by-module/Time/Time-HiRes-01.20.tar.gz">Time-HiRes-01.20.tar.gz</A></LI>
56 <A HREF="http://www.cpan.org/modules/by-module/Digest/Digest-SHA1-2.01.tar.gz">Digest-SHA1-2.01.tar.gz</A></LI>
60 <P>Copy the CPAN modules listed above to a convenient place on your computer. One good
61 place would be /usr/local/packages, and the instructions which follow will assume that
62 that's where you have put them.</P>
64 <P>Log in as 'root', and make sure you're at '/root' before you continue. Here are exactly the commands you must issue next: -</P>
67 # tar xvfz /usr/local/packages/TimeDate-1.10.tar.gz
74 # tar xvfz /usr/local/packages/Net-Telnet-3.03.tar.gz
81 # tar xvfz /usr/local/packages/Curses-1.06.tar.gz
88 # tar xvfz /usr/local/packages/Time-HiRes-01.20.tar.gz
95 # tar xvfz /usr/local/packages/Digest-SHA1-2.01.tar.gz
104 <P>Only if you need to do these (because your perl is old):-</P>
108 # tar xvfz /usr/local/packages/IO-1.20.tar.gz
112 # make install UNINST=1
115 # tar xvfz /usr/local/packages/Data-Dumper-2.101.tar.gz
116 # cd Data-Dumper-2.101
125 <P>Do not fall into the trap of thinking they're all the same, just because they
126 nearly are! Pay particular attention to the instructions of <EM>IO</EM>, above.</P>
129 <H2><A NAME="ss1.2">1.2</A> <A HREF="installation_en.html#toc1.2">Preparation</A>
132 <P>I will assume that you have already downloaded the latest tarball of
133 the DXSpider software and are ready to install it. I am assuming version
134 1.50 for this section but of course you would use the latest version.</P>
136 <P>Login as root and create a user to run the cluster under. <B><I>UNDER
137 NO CIRCUMSTANCES USE ROOT AS THIS USER!</I></B>. I am going to use
138 the name <EM>sysop</EM>. You can call it anything you wish. Depending
139 on your security requirements you may wish to use an existing user,
140 however this is your own choice.</P>
149 <P>For SuSE distributions, the command would be ..</P>
158 <P>Now set a password for the user ...</P>
164 # Retype new UNIX password:
165 passwd: all authentication tokens updated successfully
170 <H2><A NAME="ss1.3">1.3</A> <A HREF="installation_en.html#toc1.3">Installing the software</A>
173 <P>Now to unpack the DX Spider distribution, set symbolic links and group
174 permissions. Copy the tarball to /home/sysop and do the following.</P>
179 # tar xvfz spider-1.50.tar.gz
180 # ln -s ~sysop/spider /spider
181 # groupadd -g 251 spider (or another number)
186 <P>If you do not have the command <EM>groupadd</EM> available to you simply
187 add a line in /etc/group by hand.</P>
191 # vi /etc/group (or your favorite editor)
196 <P>You also need to add some others to the group, including your own callsign
197 (this will be used as an alias) and root. The finished line in /etc/group
198 should look something like this</P>
199 <P><CODE>spider:x:251:sysop,g0vgs,root</CODE></P>
201 <P>The next step is to set the permissions on the Spider directory tree and files ....</P>
205 # chown -R sysop.spider spider
206 # find . -type d -exec chmod 2775 {} \;
207 # find . -type f -exec chmod 775 {} \;
212 <P>This last step allows various users of the group <EM>spider</EM> to have
213 write access to all the directories. This is not really needed just yet
214 but will be useful when web interfaces start to appear.</P>
216 <P>Finally, you need to fix the permissions on the ax25_call and netrom_call
217 programs. Check where they are with the <EM>locate</EM> command and alter
218 the permissions with the <EM>chmod</EM> command like this ..</P>
222 # chown root ax25_call netrom_call
223 # chmod 4775 ax25_call netrom_call
228 <H2><A NAME="ss1.4">1.4</A> <A HREF="installation_en.html#toc1.4">Setting callsigns etc</A>
231 <P>Now login to your machine as the user you created earlier. In my case that
232 user is called <EM>sysop</EM>. Once logged in, issue the following commands ....</P>
239 $ cp perl/DXVars.pm.issue local/DXVars.pm
241 $ vi DXVars.pm (or your favourite editor)
246 <P>Using the distributed DXVars.pm as a a template, set your cluster callsign,
247 sysop callsign and other user info to suit your own environment. </P>
256 <P>This is the call sign of your cluster. Here in the UK we have
257 separate callsigns for our cluster nodes. If you can't use a different callsign I suggest
258 you use an SSID of '-2' for the node callsign '$mycall'.</P>
267 <P>This is the sysop user callsign, normally your own.</P>
269 <P><B>PLEASE USE CAPITAL LETTERS FOR CALLSIGNS</B></P>
271 <P>Note that this a perl file which will be parsed and executed as part of the
272 cluster. If you get it wrong then perl will complain when you start the cluster
273 process. It is important only to alter the text of any section. Some of the
274 lines look a little odd. Take this line for example ....</P>
275 <P><CODE>$myemail = "ianmaude\@btinternet.com";</CODE></P>
277 <P>There appears to be an extra slash in there. However this has to be there
278 for the file to work so leave it in.</P>
280 <P>DON'T alter any file in /spider/perl, they are overwritten with every
281 release. Any files or commands you place in /spider/local or /spider/local_cmd
282 will automagically be used in preference to the ones in /spider/perl EVEN
283 while the cluster is running!</P>
285 <P>Save the new file and change directory to ../perl ....</P>
294 <P>Now type the following command which creates the basic user file with you as
304 <H2><A NAME="ss1.5">1.5</A> <A HREF="installation_en.html#toc1.5">The client program</A>
307 <P>In earlier versions of Spider, all the processes were Perl scripts. This
308 was fine but with a lot of users your computer memory would soon be used up.
309 To combat this a new client was written in "C". This client only works for
310 <EM>incoming</EM> connects at the moment. Before you can use it though it
311 has to be "made". CD to /spider/src and type <EM>make</EM>. You
312 should see the output on your screen and hopefully now have a small C program
313 called <EM>client</EM>. Leave it in this directory.</P>
316 <H2><A NAME="ss1.6">1.6</A> <A HREF="installation_en.html#toc1.6">Starting up for the first time</A>
319 <P>We can now bring spider up for the first time and see if all is well or not!
320 It should look something like this ...</P>
325 DXSpider DX Cluster Version 1.50

328 loading band data ...
329 loading user file system ...

331 reading existing message headers
333 orft we jolly well go ...
338 <P>If all is well then login on another term or console as <EM>sysop</EM> and
339 cd to /spider/src. Now issue the following command ...</P>
348 <P>This should log you into the cluster as the sysop under the alias callsign we
349 set earlier. In this case the callsign is G0VGS. The cluster callsign is set
350 in the DXVars.pm file in /spider/local. In this case we will assume that this
351 was set as GB7MBC. You should therefore see this when you login ....</P>

360 <P>If you do, congratulations! If not, look over the instructions again, you
361 have probably missed something out. You can shut spider down again with the
371 <P>and both the cluster and the client should return to Linux prompts.</P>
