2. Linux quick installation guide
In addition to the standard Red Hat distribution you will require the
- following modules from http://www.cpan.org/CPAN.html ...
+ following modules from http://www.cpan.org/CPAN.html , please note
+ however that with later versions of perl, some of these modules may be
+ included with the distribution. Get the modules anyway and try to
+ install as below. If they complain, they are probably already a part
+ of your perl distribution.
-
-
-
-
+ For SUSE distributions, the command would be ..
+
+
+
+ # useradd -m sysop
+
+
+
+
+
Now set a password for the user ...
+
If you do not have the command groupadd available to you simply add a
line in /etc/group by hand.
+
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
The next step is to set the permissions on the Spider directory tree
and files ....
-
-
# chown -R sysop.spider spider
# find . -type d -exec chmod 2775 {} \;
# find . -type f -exec chmod 775 {} \;
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 ....
+ environment.
- $myemail = "ianmaude\@btinternet.com";
- There appears to be an extra slash in there. However this has to be
- there for the file to work so leave it in.
+ $mycall = "GB7DJK";
+
+
+
+
+
+ This is the call sign of your cluster. If you use an SSID then
+ include it here also.
+
+
+
+ $myalias = "G1TLH";
+
+
+
+ This is the sysop user callsign, normally your own.
PLEASE USE CAPITAL LETTERS FOR CALLSIGNS
+ 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 ....
+
+ $myemail = "ianmaude\@btinternet.com";
+
+
+ There appears to be an extra slash in there. However this has to be
+ there for the file to work so leave it in.
+
+
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
$ cd ../perl
+
+
+
Now type the following command which creates the basic user file with
you as the sysop.
- 1.5. Starting up for the first time
+ 1.5. The client program
+
+ 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 incoming connects at the moment. Before you can
+ use it though it has to be "made". CD to /spider/src and type make.
+ You should see the output on your screen and hopefully now have a
+ small C program called client. Leave it in this directory.
+
+
+
+ 1.6. Starting up for the first time
We can now bring spider up for the first time and see if all is well
or not! It should look something like this ...
- $ ./cluster.pl
- DXSpider DX Cluster Version 1.47
- Copyright (c) 1998 Dirk Koopman G1TLH
- loading prefixes ...
- loading band data ...
- loading user file system ...
- starting listener ...
- reading existing message headers
- reading cron jobs
- orft we jolly well go ...

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 ....

Spider should now be running and you should be able to login using the
client program.
o Login as root
-
o Enter the correct line in ax25d.conf (root)
o Enter the correct line in /etc/services (root)
o killall -HUP inetd (root)
+
Spider should now be able to accept logins via telnet, netrom and
ax25.
+
or, if you wish your users to be able to use SSID's on their callsigns
..
+
For most purposes this is not desirable. The only time you probably
will need this is when you need to allow other cluster nodes that are
using SSID's in. In this case it would probably be better to use the

-
Then add a line in /etc/inetd.conf like this ....
-
Now login as sysop and cd spider/src. You can test that spider is
accepting telnet logins by issuing the following command ....
+
You should get a login prompt and on issuing a callsign, you will be
given access to the cluster. Note, you will not get a password login.
There seems no good reason for a password prompt to be given so it is

Start up the cluster as you did before and login as the sysop with
client. The cluster node I am wanting to make a connection to is
GB7BAA but you would obviously use whatever callsign you required. At

The connect scripts consist of lines which start with the following
keywords or symbols:-
-
-
-
-
-
-
- timeout 60
- abort (Busy|Sorry|Fail)
- # don't forget to chmod 4775 netrom_call!
- connect ax25 /usr/sbin/netrom_call bbs gb7djk g1tlh
- # you can leave this out if you call the script 'gb7dxm'
- client gb7dxm ax25
+ timeout 60
+ abort (Busy|Sorry|Fail)
+ # don't forget to chmod 4775 netrom_call!
+ connect ax25 /usr/sbin/netrom_call bbs gb7djk g1tlh
+ # you can leave this out if you call the script 'gb7dxm'
+ client gb7dxm ax25
client gb7djk telnet

-
Both these examples assume that everything is set up properly at the
other end. You will find other examples in the /spider/examples
directory.
+
This will start a connection using the script called gb7djk-1. You
can follow the connection by watching the term or console from where
you started cluster.pl. From version 1.47 onwards, you will need to
-

This means if a node is unreachable, it will continue sending logins
and logouts to users even though it is not actually connecting. To
avoid this use the following line ...
-
-
-
-
-
-
-
-
In a script, this might look like ...
+
So, the first connection is made by Spider. This is fine as Spider
uses the Net_Telnet script from within perl. This actually uses TCP
rather than TELNET so no negotiation will be done on the first
automatically.
+
This is not only a way to start the cluster automatically, it also
works as a watchdog, checking the sanity of DXSpider and respawning it
should it crash for any reason. Before doing the following, shutdown
This line works fine for RedHat distributions. It is also fine for
SuSE up to 7.0. From Suse 7.1 you need to add runlevels 2 and 5 like
this ...
+
+
+
DX:235:respawn:/bin/su -c "/usr/bin/perl -w /spider/perl/cluster.pl" sysop >/dev/tty7
download the necessary software bits and bobs directly to it. There
are other ways, but this is preferable.

o Another cup of good, strong tea
o If all goes according to plan, about an hour to spare
+
I'm not going to bother you with exhaustive details of the rest of
them, but suffice it to say you need to:
because it suits me.

-
-
4.6. Getting Spider
Get the current version of the DX Spider distribution. This needs to
- cd \spider\local
+ cd \spider\local
o $mycall - Should hold the callsign of your DX Cluster
-
o $myname - The SysOp's first name
o $myalias - the SysOp's callsign. Cannot be the same as $mycall!
o $passwd - password that matches $login
+
+
5.2. Setting up the initial user files
Next you need to create the initial user files, etc. A tool is
-
- perl cluster.pl
+ perl cluster.pl
- cd \spider\perl
- perl winclient.pl
+
+ cd \spider\perl
+ perl winclient.pl
connected to anything particularly useful at any given moment. Contact
me by Email if you want me to set up a connection for you.

6. General Information
The following relates to all versions of DXSpider and is not platform
+
+
The callsign involved will be the callsign of the cluster node you are
going to connect to. This will now check every 10 minutes to see if
gb7xxx is connected, if it is then nothing will be done. If it is
