1. Linux Installation
1.1. Introduction
This section describes the installation of DX Spider v1.47 on a RedHat
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.
I am assuming a general knowledge of Linux and its commands. You
should know how to use tar and how to edit files using your favourite
editor.
The crucial ingredient for all of this is Perl. Earlier versions of
Spider required perl 5.004, however it is now STRONGLY recommended
that you use at least version 5.005_03 as this is the version being
used in the development of Spider.
In addition to the standard Red Hat distribution you will require the
following modules from http://www.cpan.org/CPAN.html ...
o Data-Dumper-2.10.tar.gz
o TimeDate-1.10.tar.gz
o IO-1.20.tar.gz (for perl 5.00403 and lower)
o Net-Telnet-3.02.tar.gz
o Curses-1.06.tar.gz
o Time-HiRes-01.20.tar.gz
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 that's where you have put
them.
Log in as 'root', and make sure you're at '/root' before you continue.
Here are exactly the commands you must issue next: -
# tar xvfz /usr/local/packages/Data-Dumper-2.10.tar.gz
# cd Data-Dumper-2.10
# perl Makefile.PL
# make test
# make install
# cd ..
#
# tar xvfz /usr/local/packages/TimeDate-1.10.tar.gz
# cd TimeDate-1.10
# perl Makefile.PL
# make test
# make install
# cd ..
#
# tar xvfz /usr/local/packages/IO-1.20.tar.gz
# cd IO-1.20
# perl Makefile.PL
# make test
# make install UNINST=1
# cd ..
#
# tar xvfz /usr/local/packages/Net-Telnet-3.02.tar.gz
# cd Net-Telnet-3.02
# perl Makefile.PL
# make test
# make install
# cd ..
#
# tar xvfz /usr/local/packages/Curses-1.06.tar.gz
# cd Curses-1.06
# perl Makefile.PL
# make test
# make install
# cd ..
#
# tar xvfz /usr/local/packages/Time-HiRes-01.20.tar.gz
# cd Time-HiRes-01.20
# perl Makefile.PL
# make test
# make install
# cd ..
Do not fall into the trap of thinking they're all the same, just
because they nearly are! Pay particular attention to the instructions
of IO, above.
1.2. Preparation
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 1.47 for this section but of course you would use the latest
version.
Login as root and create a user to run the cluster under. UNDER NO
CIRCUMSTANCES USE ROOT AS THIS USER!. I am going to use the name
sysop. 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.
# adduser -m sysop
For SUSE distributions, the command would be ..
# useradd -m sysop
Now set a password for the user ...
# passwd sysop
# New UNIX password:
# Retype new UNIX password:
passwd: all authentication tokens updated successfully
1.3. Installing the software
Now to unpack the DX Spider distribution, set symbolic links and group
permissions. Copy the tarball to /home/sysop and do the following.
# cd ~sysop
# tar xvfz spider-1.47.tar.gz
# ln -s ~sysop/spider /spider
# groupadd -g 251 spider (or another number)
If you do not have the command groupadd available to you simply add a
line in /etc/group by hand.
# vi /etc/group (or your favorite editor)
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
spider:x:251:sysop,g0vgs,root
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 {} \;
This last step allows various users of the group spider 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.
Finally, you need to fix the permissions on the ax25_call and
netrom_call programs. Check where they are with the locate command
and alter the permissions with the chmod command like this ..
# chown root ax25_call netrom_call
# chmod 4775 ax25_call netrom_call
1.4. Setting callsigns etc
Now login to your machine as the user you created earlier. In my case
that user is called sysop. Once logged in, issue the following
commands ....
$ cd /spider
$ mkdir local
$ mkdir local_cmd
$ cp perl/DXVars.pm.issue local/DXVars.pm
$ cd local
$ vi DXVars.pm (or your favourite editor)
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 ....
$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.
PLEASE USE CAPITAL LETTERS FOR CALLSIGNS
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!
Save the new file and change directory to ../perl ....
$ cd ../perl
Now type the following command which creates the basic user file with
you as the sysop.
$ ./create_sysop.pl
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 all is well then login on another term or console as sysop and cd
to /spider/src. Now issue the following command ...
$ ./client
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 ....
G0VGS de GB7MBC 19-Nov-1999 2150Z >
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 ....
shutdown
and both the cluster and the client should return to Linux prompts.
2. Linux quick installation guide
This section is designed for experienced Spider sysops who want to
install Spider from scratch. It is simply a check list of things that
need to be done without any explanations. The name in brackets at the
end of each line is the user that should be doing that process.
o Login as root
o Get the additional CPAN modules and install them (root)
o Create the "sysop" user and set a password (root)
o Put the Spider tarball in sysop and untar it (root)
o ln -s sysop/spider /spider (root)
o groupadd -g 251 spider (root)
o Add any more users you need to the group entry in /etc/group (root)
o Set the permissions on the spider tree (root)
o Fix permissions on ax25_call and netrom_call (root)
o Login as the sysop user
o cd to /spider (sysop)
o mkdir local (sysop)
o mkdir local_cmd (sysop)
o cp perl/DXVars.pm.issue local/DXVars.pm (sysop)
o cd to /spider/local and edit DXVars to set your details (sysop)
o cd ../perl (sysop)
o ./create_sysop.pl (sysop)
o ./cluster.pl (sysop)
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 Enter the correct line in /etc/inetd.conf (root)
o killall -HUP inetd (root)
Spider should now be able to accept logins via telnet, netrom and
ax25.
o Login as sysop
o Start the cluster (sysop)
o set/node and type for links (sysop)
o Write any connect scripts (sysop)
o Edit /spider/crontab as required (sysop)
o Edit any other files as necessary (sysop)
o Set filters, hops and forwarding files (sysop)
o Login as root
o Enter the correct line in /etc/inittab (root)
3. Configuration
3.1. Allowing ax25 connects from users
As stated previously, the aim of this document is not to tell you how
to configure Linux or the ax25 utilities. However, you do need to add
a line in your ax25d.conf to allow connections to DXSpider for your
users. For each interface that you wish to allow connections on, use
the following format ...
default * * * * * * - sysop /spider/src/client client %u ax25
or, if you wish your users to be able to use SSID's on their callsigns
..
default * * * * * * - sysop /spider/src/client client %s ax25
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
first example and then add a specific line for that node like this:
GB7DJK-2 * * * * * * - sysop /spider/src/client client gb7djk-2 ax25
default * * * * * * - sysop /spider/src/client client %u ax25
3.2. Allowing telnet connects from users
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 here will continue to work just fine.
Allowing telnet connections is quite simple. Firstly you need to add
a line in /etc/services to allow connections to a port number, like
this ....
spdlogin 8000/tcp # spider anonymous login port
Then add a line in /etc/inetd.conf like this ....
spdlogin stream tcp nowait root /usr/sbin/tcpd /spider/src/client login telnet
Once this is done, you need to restart inetd like this ....
killall -HUP inetd
Now login as sysop and cd spider/src. You can test that spider is
accepting telnet logins by issuing the following command ....
./client login telnet
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
not asked for.
Assuming all is well, then try a telnet from your linux console ....
telnet localhost 8000
You should now get the login prompt and be able to login as before.
3.3. Setting up telnet connects (from 1.47 onwards)
From version 1.47 you can choose to allow the perl cluster.pl program
to allow connections directly (i.e. not via the /spider/src/client
interface program). If you are using Windows then this is the only
method available of allowing incoming telnet connections.
To do this you need first to remove any line that you may previously
have set up in /etc/inetd.conf. Remember to:-
killall -HUP inetd
to make the change happen...
Having done that, you need to copy the file /spider/perl/Listeners.pm
to /spider/local and then edit it. You will need to uncomment the line
containing "0.0.0.0" and select the correct port to listen on. So that
it looks like this:-
@listen = (
["0.0.0.0", 8000],
);
As standard, the listener will listen on all interfaces
simultaneously. If you require more control than this, you can
specify each interface individually:-
@listen = (
["gb7baa.dxcluster.net", 8000],
["44.131.16.2", 6300],
);
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.
Restart the cluster.pl program to enable the listener.
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.
3.4. Setting up for AGW Engine (1.47 onwards)
AGW Engine is a Windows based ax25 stack. You can connect to an AGW
engine from Linux as well as Windows based machines.
In order to enable access to an AGW Engine you need to copy
/spider/perl/AGWConnect.pm to /spider/local and edit it. Specifically
you must:-
o set $enable to 1.
o set $login and $passwd to the values set up in your AGW
installation. If you haven't set any there, then you should not
touch these values.
o You can connect to a remote AGW engine (ie on some other machine)
by changing $addr and $port appropriately.
o Restart the cluster.pl program
3.5. Setting up node connects
In order to allow cluster node connections, spider needs to know that
the connecting callsign is a cluster node. This is the case whether
the connect is incoming or outgoing. In spider this is a simple task
and can be done in runtime.
Later versions of Spider can distinguish different software and treat
them differently. For example, the WCY beacon cannot be handles by
AK1A type nodes as AK1A does not know what to do with PC73. There are
4 different types of node at present and although they may not have
any major differences at the moment, it allows for compatibility. The
4 types are ...
set/node (AK1A type)
set/spider
set/dxnet
set/clx
For now, we will assume that the cluster we are going to connect to is
an AK1A type node.
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 prompt type ...
set/node gb7baa
The case does not matter as long as you have a version of DXSpider
later than 1.33. Earlier versions required the callsign to be in
upper case.
That is now set, it is as simple as that. To prove it, login on yet
another console as sysop, cd to spider/src and issue the command ...
./client gb7baa (using the callsign you set as a node)
You should get an initialisation string from DXSpider like this ...
./client gb7baa
PC38^GB7MBC^~
If the callsign you just set up as a cluster node is for an incoming
connect, this is all that needs to be done. If the connection is to
be outgoing then a connection script needs to be written.
Sometimes you make a mistake... Honest, it does happen. If you want
to make a node back to being a normal user, regardless of what type it
is, do:
unset/node gb7baa
3.6. Connection scripts
Because DXSpider operates under Linux, connections can be made using
just about any protocol; AX25, NETRom, tcp/ip, ROSE etc are all
possible examples. Connect scripts live in the /spider/connect
directory and are simple ascii files. Writing a script for
connections is therefore relatively simple.
The connect scripts consist of lines which start with the following
keywords or symbols:-
# All lines starting with a # are ignored, as are completely blank
lines.
timeout
timeout followed by a number is the number of seconds to wait
for a command to complete. If there is no timeout specified in
the script then the default is 60 seconds.
abort
abort is a regular expression containing one or more strings to
look for to abort a connection. This is a perl regular
expression and is executed ignoring case.
connect
connect followed by ax25, agw (for Windows users) or telnet and
some type dependent information. In the case of a telnet
connection, there can be up to two parameters. The first is the
ip address or hostname of the computer you wish to connect to
and the second is the port number you want to use (this can be
left out if it is a normal telnet session). In the case of an
ax25 session then this would normally be a call to ax25_call or
netrom_call as in the example above. It is your responsibility
to get your node and other ax25 parameters to work before going
down this route!
' line in a chat type script. The words/phrases normally come in
pairs, either can be empty. Each line reads input from the
connection until it sees the string (or perl regular expression)
contained in the left hand string. If the left hand string is
empty then it doesn't read or wait for anything. The comparison
is done ignoring case. When the left hand string has found what
it is looking for (if it is) then the right hand string is sent
to the connection. This process is repeated for every line of
chat script.
client
client starts the connection, put the arguments you would want
here if you were starting the client program manually. You only
need this if the script has a different name to the callsign you
are trying to connect to (i.e. you have a script called other
which actually connects to GB7DJK-1 [instead of a script called
gb7djk-1]).
There are many possible ways to configure the script but here are
three examples, one for a NETRom/AX25 connect, one for AGW engines and
one for tcp/ip.
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)
# this does exactly the same as the previous example
# the '1' is the AGW port number to connect thru for g1tlh
connect agw 1 g1tlh
# you can leave this out if you call the script 'gb7dxm'
client gb7dxm ax25
timeout 15
connect telnet dirkl.tobit.co.uk
# tell GB7DJK-1 that it is connected to GB7DJK
# you can leave this out if you call this script 'gb7djk'
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.
3.7. Starting the connection
You start the connection, from within a sysop enabled cluster login,
by typing in the word connect followed by a script name like this ....
G0VGS de GB7MBC 13-Dec-1998 2041Z >connect gb7djk-1
connection to GB7DJK-1 started
G0VGS de GB7MBC 13-Dec-1998 2043Z >
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
set/debug connect first. You should see something like this ...
<- D G1TLH connect gb7djk-1
-> D G1TLH connection to GB7DJK-1 started
-> D G1TLH G1TLH de GB7DJK 13-Dec-1998 2046Z >
timeout set to 15

<- D GB7DJK-1 PC18^ 1 nodes, 0 local / 1 total users Max users 0 Uptime
0 00:00^5447^~
etc
With later versions of Spider there is a set/login command for users.
This tells them when a user or node logs in or out. If you do not add
a line to your scripts after the final line (or before the client line
which should always be last if needed) then the login/logout
information will be sent to users before the login actually completes.
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 ...
timeout 35
abort (Busy|Sorry|Fail)
connect telnet mary 3000
3.8. Telnet echo
Cluster links in particular suffer greatly from the presence of telnet
echo. This is caused by the telnet negotiation itself and can create
at worst severe loops. At best it creates unnecessary bandwidth and
large logfiles! There are things that can be done to limit this
problem but will not always work dependent on the route taken to
connect.
Telnet echo itself should only be a problem if the connection is being
made to the telnet port (23). This port uses special rules that
include echo negotiation. If the connection is to a different port,
such as 7300, this negotiation does not happen and therefore no echo
should be present.
Sometimes it is not possible to make a direct connection to another
node and this can cause problems. There is a way of trying to
suppress the telnet echo but this will not always work, unfortunately
it is difficult to be more specific. Here is an example of what I
mean ...
timeout 35
abort (Busy|Sorry|Fail)
connect telnet mary.lancs.ac.uk
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
connection. Once connected to mary.lancs.ac.uk, the command is sent
to suppress echo. Now a telnet is made to a cluster node that is
accepting connections on port 23. The problem with this link is that
the negotiation is made by the remote machine, therefore you have no
control over it. The chances are that this link will create echo and
there will be no way you can stop it.
3.9. Autostarting the cluster
Ok, you should now have DXSpider running nicely and allowing connects
by cluster nodes or users. However, it has to be shutdown and
restarted manually. It would be much easier to have it start
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
the cluster as you did earlier.
Login as root and bring up the /etc/inittab file in your favourite
editor. Add the following lines to the file near the end ...
##Start DXSpider on bootup and respawn it should it crash
DX:3:respawn:/bin/su -c "/usr/bin/perl -w /spider/perl/cluster.pl" sysop >/dev/tty7
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
The line required for Slackware distributions is slightly different.
My thanks to Aurelio, PA3EZL for this information.
DX:23:respawn:/bin/su - sysop -c "/usr/bin/perl -w /spider/perl/cluster.pl" >/dev/tty7
This will automatically start DXSpider on tty7 (ALT-F7) on bootup and
restart it should it crash for any reason.
As root type the command telinit q. DXSpider should start up
immediately. You will see the output on tty7 and if you login as
sysop you should find everything running nicely.
4. Microsoft Windows Installation
4.1. Introduction
IMPORTANT:
What you'll be left with once you've followed these instructions is
(hopefully) a working DX Spider v1.47 system that is capable of
accepting or originating "internet" connections, plus inbound AX.25
and TCP/IP radio connections. If the absence of outbound radio
connections is a serious limitation for you, it would be better for
you to wait a couple more weeks until this support has been added.
On the other hand, you may have an enquiring mind, or better yet, may
be looking for a useful way of connecting your current (perhaps) AK1A
cluster "to the internet" via some networking mechanism (BPQEther,
etc) or other. I won't be producing instructions for the latter case,
because I don't have an AK1A to play with. But someone might ...
Whatever, this document is intended to get you started with DX Spider
in a Microsoft Windows (TM) environment. It's not intended to teach
you anything other than how to perform a minimum configuration of a DX
Spider installation and have it able to connect across "the internet"
to other DX Clusters, while accepting inbound TELNET and radio
connections.
4.2. The requirements
The very first things you're going to need are (in order of
importance):-
o A cup of good, strong tea
o A supported Windows platform with an internet connection so you can
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
o Plenty of good, strong tea
4.3. The system
The platform I used to generate these instructions was a "vanilla"
Microsoft Windows Me 4.90.3000 system, with a 700MHz AMD Athlon
processor and 96 Mb memory. I've also personally verified that it runs
on my laptop (Pentium 266MHz, 32 Mb memory, Windows 98 SE v4.10.2222
A) and a computer that I assembled from a random pile of junk (AMD
K6-2 333MHz, 64 Mb memory, Windows 98 v4.10.1998). As a result, I have
reason to believe that what I'm about to describe will perform equally
on any 32-bit MS Windows environment with 32 Mb of memory.
Because of the changes that have recently been made to the core
"cluster.pl" module and the introduction of a very lightweight
"winclient.pl", I have a sneaking suspicion that this will now run on
any platform that has reasonably complete support for Perl. Is there
someone out there with both an enquiring mind and (say) a Macintosh,
for instance?
Please bear in mind, though, that my instructions relate solely to how
to get this going under a Microsoft Windows environment, and I have
zero intention of trying to make them say otherwise.
4.4. Perl
Install your chosen Perl environment. Unless you have a very good
reason for not doing so, I strongly suggest that you use ActivePerl
v5.6. For my testing & development, I used build 623. You can get
this from:-
http://www.activestate.com/Products/ActivePerl/Download.html
You will need to choose either the MSI or the AS package. My
recommendation is that you choose the MSI package and deal with the
consequences if your system isn't equipped with support for the latest
MS Installer; you'll be better off in the long run. The build 623
download is 7,460 KB, so now is a really good time to have some tea if
you're on a slow dial-up connection.
During installation, please ensure that you do choose the options to
"Add Perl to the PATH environment variable" and "Create Perl file
extension association"; it will make your life so much easier. Once
the installation is finished, be sure to reboot your PC. You probably
won't be told anywhere else that this needs to be done now, but it
does. Really.
Once you've rebooted, open a "DOS box" (Start > Run > command might do
it, if you can't find it elsewhere) and from wherever it lands, type
PERL -v <ENTER> (it's better if that's a lower-case be rewarded with
some interesting information about your Perl installation. If you're
not, you must go back to the beginning and discover what went wrong
and fix it. It's pointless to proceed unless this simple check is
passed. Assuming it did work, you may now move on.
4.5. Additional packages
Some extensions ("packages") need to be added to the base Perl
distribution, and we'll do this next. If you're using the Perl I
recommended, and don't know any better for yourself, then just blindly
following these instructions will work just fine. If that didn't
describe you, then you're on your own.
Visit the following URL:
http://www.activestate.com/PPMPackages/zips/6xx-builds-only/
and download the following files:-
Data-Dumper.zip
Net-Telnet.zip
TimeDate.zip
Time-HiRes.zip
DB_File.zip
Make yourself a convenient directory to unpack all of these zip files
into (I put mine in "D:\ppm>") and do the following (the bits you type
in are blue ). Note that where these files land will be directly
related to where you chose to install your ActivePerl (mine, as you
can probably guess from what follows, went into "D:\Perl"):-
D:\ppm>ppm install Data-Dumper.ppd
Installing package 'Data-Dumper.ppd'
Installing D:\Perl\site\lib\auto\Data\Dumper\Dumper.bs
Installing D:\Perl\site\lib\auto\Data\Dumper\Dumper.dll
Installing D:\Perl\site\lib\auto\Data\Dumper\Dumper.exp
Installing D:\Perl\site\lib\auto\Data\Dumper\Dumper.lib
Installing D:\Perl\html\site\lib\auto\Data\Dumper\Dumper.html
Installing D:\Perl\site\lib\Data\Dumper\Dumper.pm
Writing D:\Perl\site\lib\auto\Data\Dumper\Dumper.packlist
D:\ppm>
I'm not going to bother you with exhaustive details of the rest of
them, but suffice it to say you need to:
ppm install DB_File.ppd
ppm install Net-Telnet.ppd
ppm install TimeDate.ppd
ppm install Time-HiRes.ppd
If all that seemed to work OK, time to move along. Before anyone who
is familiar with PPM tells me that we didn't need to download and keep
those files locally, I knew that. I also knew that PPM is sometimes
awkward to configure via firewalls, and that sometimes the
repositories don't always work the way we'd hope. I do it that way
because it suits me.
4.6. Getting Spider
Get the current version of the DX Spider distribution. This needs to
be v1.47 or later. You've got two ways (currently) of getting this;
either get a CVS update from sourceforge (if you don't know what this
is, then it isn't for you) or get my package from:-
http://www.dcc.rsgb.org/WinSpider.zip
or if you want the lastest CVS version (which is produced every night)
http://www.dxcluster.org/download/CVSlatest.tgz
If you went down the CVS route, then everything will be nicely set out
on your local disk. If you got the ZIP file, unpack it to somewhere
convenient. The following examples assume that you put it on drive
"C:\", for convenience.
NOTE: This distribution method will go away as soon as the first v1.47
tarball is released. You can use WinZip to unpack that, and my life
will be made easier by not needing to keep this .ZIP file updated.
5. Installing the software
Ensure that your CVS session or your unZIPped file have left you with
a directory "C:\spider\local"; if not, go to "C:\spider\" and create
one. If "C:\spider" is missing, go back and figure out why, because it
shouldn't be.
Now create your own local copy of the DXVars.pm file by:-
copy c:\spider\perl\DXVars.pm.issue
c:\spider\local\DXVars.pm
Now you'll need to edit this file using a text editor. If nothing
else, you can simply
cd \spider\local
and then
notepad DXVars.pm
to bring up an editor window containing the file. As an absolute
minimum you must adjust the following items in DXVars.pm:-
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!
You really also ought to update the $mylatitude, $mylongitude, $myqth
and $myemail variables. And unless you are absolutely certain you know
what you're doing, you should change nothing else in this file.
5.1. The AGW packet engine
On the assumption that you'll be using the SV2AGW Packet Engine to
interface your radios to the cluster, you should now create your own
local copy of AGWConnect.pm by:-
copy c:\spider\perl\AGWConnect.pm
c:\spider\local\AGWConnect.pm
and then
notepad AGWConnect.pm
to bring up an editor window containing the file. You must consider
adjusting the following items in AGWConnect.pm:-
o $enable - set to '1' to enable AGWPE interface
o $login - the login ID you chose when you set up the SV2AGW
security :-)
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
supplied which will do this for you. To run the tool:-
cd \spider\perl
perl create_sysop.pl
If all goes according to plan, you will see no output from this
program, and after a brief wait, your DOS prompt will be returned.
Depending on how brave you are, you might now care to try the
following:-
perl cluster.pl
If you did everything you were told, your DOS window will now hold a
display which looks something like:-
DXSpider DX Cluster Version 1.47

Now, if that's what you've got, you are very nearly home and dry (in
as far as these particular experiments are concerned, anyhow)
To access your new cluster (from the local machine) find yourself
another "DOS box" and do the following:-
cd \spider\perl
perl winclient.pl
If you are rewarded with a display which looks something like:-
Hello Iain, this is GB7SJP in Amersham, Bucks running DXSpider V1.47
Cluster: 1 nodes, 1 local / 1 total users Max users 2 Uptime 0 00:00
M0ADI de GB7SJP 4-Mar-2001 1511Z >
You've arrived. Try some commands, and see how they feel. (In case you
were wondering, "Iain", "M0ADI" and "GB7SJP" all came from the version
of DXVars.pm that was on the machine when I started the winclient.pl)
5.3. Incoming telnets
If you want to enable inbound "TELNET" connections, you've got a
little more work to do. From a handy "DOS box" that's not doing
anything else, do the following:-
copy \spider\perl\listeners.pm \spider\local
cd \spider\local
notepad listeners.pm
The following lines need attention:-
["0.0.0.0", 7300],
On my machine, I've simply uncommented the "0.0.0.0" entry by removing
the '#' from the front of the line.
If you don't have a static hostname for your machine, and you intend
to allow folk to connect to your machine across the internet, then I'd
suggest you pay a visit to www.dyndns.org and create one for yourself.
While it's free, it will take a modest an amount of effort on your
part to read, understand and implement what needs to be done to set
this up.
5.4. Connecting to other clusters
If you want to connect this to another cluster, then you'll want to
negotiate a link with someone. For experimental purposes, I'm happy to
allow folk to connect to GB7DXA (spud.ath.cx), on the understanding
that the system may or may not be there and may or may not be
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
related.
6.1. The crontab file
Login as sysop and create a file in /spider/local_cmd called crontab.
Edit it with your favourite editor and add a line like this (I have
included a comment)
# check every 10 minutes to see if gb7xxx is connected and if not
# start a connect job going
0,10,20,30,40,50 * * * * start_connect('gb7xxx') unless connected('gb7xxx')
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
not, then a connect attempt will be started.
There are probably lots of other things you could use this crontab
file for. If you want to know more about it, look at the DXSpider
website at the cron page where it is explained more fully.
