<P>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.
<P>
<H3>Connection scripts</H3>
<P>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.
<P>
<P>The connect scripts consist of lines which start with the following keywords or symbols:-
<P>
<P>
<PRE>
# All lines starting with a # are ignored, as are wholly 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 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!
' ' is the delimiting character for a word or phrase of an expect/send
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]).
</PRE>
<P>
<P>There are many possible ways to configure the script but here are two examples, one for a NETRom/AX25 connect and one for tcp/ip.

<H2><A NAME="ss2.4">2.4 Automating things</A>
</H2>
<P>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 and if connection scripts fail they have to be started again manually too, not much use if you are not at the console!
So, in this section we will automate both. Firstly starting the cluster.
<P>
<H3>Autostarting the cluster</H3>
<P>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.
<P>
<P>Login as root and bring up the /etc/inittab file in your favourite editor. Add the following lines to the file near the end ...
<P>
<BLOCKQUOTE><CODE>
<PRE>
##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
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>This will automatically start DXSpider on tty7 (ALT-F7) on bootup and restart it should it crash for any reason.
<P>
<P>As root type the command <EM>telinit q</EM>. DXSpider should start up immediately. You will see the output on tty7 and if you login as <EM>sysop</EM> you should find everything running nicely.
<P>
<P>So far so good, now to automate script connections...
<P>
<H3>The crontab file</H3>
<P>Login as <EM>sysop</EM> 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)
<P>
<BLOCKQUOTE><CODE>
<PRE>
# 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') if !connected('gb7xxx')
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>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.
<P>
<P>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
<A HREF="http://www.dxcluster.org/cron.html">DXSpider</A> website at the cron page where it is explained more fully.
<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.

It has a set of default hops on the various PC frames and also a set for each node you want to alter the hops for. You may be happy with the default settings of course, but this powerful tool can help to protect and improve the network. The file will look something like this ...

<P>Each set of hops is contained within a pair of curly braces and contains a series of PC frame types. PC11 for example is a DX spot. The figures here are not exhaustive but should give you a good idea of how the file works.

<H2><A NAME="ss3.2">3.2 Isolating networks</A>
<H2><A NAME="ss3.2">3.2 Allowing telnet connects from users</A>
</H2>
<P>It is possible to isolate networks from each other on a "gateway" node using the
<EM>set/isolate &lt;node call&gt;</EM> command.
<P>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 ....
<P>
<P>The effect of this is to partition an isolated network completely from another
nodes connected to your node. Your node will appear on and otherwise behave
normally on every network to which you are connected, but data from an isolated
network will not cross onto any other network or vice versa. However all the
spot, announce and WWV traffic and personal messages will still be handled
locally (because you are a real node on all connected networks), that is locally
connected users will appear on all networks and will be able to access and
receive information from all networks transparently. All routed messages will
be sent as normal, so if a user on one network knows that you are a gateway for
another network, he can still still send a talk/announce etc message via your
node and it will be routed across.

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]).

<P>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 <I>before</I> 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 ...

<H2><A NAME="ss3.4">3.4 Automating things</A>
</H2>
<P>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 and if connection scripts fail they have to be started again manually too, not much use if you are not at the console!
So, in this section we will automate both. Firstly starting the cluster.
<P>
<H3>Autostarting the cluster</H3>
<P>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.
<P>
<P>Login as root and bring up the /etc/inittab file in your favourite editor. Add the following lines to the file near the end ...
<P>
<BLOCKQUOTE><CODE>
<PRE>
##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
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>This will automatically start DXSpider on tty7 (ALT-F7) on bootup and restart it should it crash for any reason.
<P>
<P>As root type the command <EM>telinit q</EM>. DXSpider should start up immediately. You will see the output on tty7 and if you login as <EM>sysop</EM> you should find everything running nicely.
<P>
<P>So far so good, now to automate script connections...
<P>
<H3>The crontab file</H3>
<P>Login as <EM>sysop</EM> 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)
<P>
<BLOCKQUOTE><CODE>
<PRE>
# 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') if !connected('gb7xxx')
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>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.
<P>
<P>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

<H2><A NAME="s4">4. Hop control</A></H2>
<P>Starting with version 1.13 there is simple hop control available on a per
node basis. Also it is possible to isolate a network completely so that you
get all the benefits of being on that network, but can't pass on information
from it to any other networks you may be connected to (or vice versa).
<P>
<H2><A NAME="ss4.1">4.1 Basic hop control</A>
</H2>
<P>In /spider/data you will find a file called hop_table.pl. This is the file that controls your hop count settings. It has a set of default hops on the various PC frames and also a set for each node you want to alter the hops for. You may be happy with the default settings of course, but this powerful tool can help to protect and improve the network. The file will look something like this ...
<P>
<BLOCKQUOTE><CODE>
<PRE>
#
# hop table construction
#
package DXProt;
# default hopcount to use
$def_hopcount = 5;
# some variable hop counts based on message type
%hopcount =
11 => 10,
16 => 10,
17 => 10,
19 => 10,
21 => 10,
);
# the per node hop control thingy
%nodehops =
GB7ADX => { 11 => 8,
12 => 8,
16 => 8,
17 => 8,

},
};
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>Each set of hops is contained within a pair of curly braces and contains a series of PC frame types. PC11 for example is a DX spot. The figures here are not exhaustive but should give you a good idea of how the file works.
<P>
<P>You can alter this file at any time, including whilst the cluster is running. If you alter the file during runtime, the command <EM>load/hops</EM> will bring your changes into effect.
<P>
<H2><A NAME="ss4.2">4.2 Isolating networks</A>
</H2>
<P>It is possible to isolate networks from each other on a "gateway" node using the
<EM>set/isolate &lt;node_call&gt;</EM> command.
<P>
<P>The effect of this is to partition an isolated network completely from another
nodes connected to your node. Your node will appear on and otherwise behave
normally on every network to which you are connected, but data from an isolated
network will not cross onto any other network or vice versa. However all the
spot, announce and WWV traffic and personal messages will still be handled
locally (because you are a real node on all connected networks), that is locally
connected users will appear on all networks and will be able to access and
receive information from all networks transparently. All routed messages will
be sent as normal, so if a user on one network knows that you are a gateway for
another network, he can still still send a talk/announce etc message via your
node and it will be routed across.
<P>
<P>The only limitation currently is that non-private messages cannot be passed down
isolated links regardless of whether they are generated locally. This will change
when the bulletin routing facility is added.
<P>
<P>If you use isolate on a node connection you will continue to receive all information from the isolated partner, however you will not pass any information back to the isolated node. There are times when you would like to forward only spots across a link (maybe during a contest for example). To do this, isolate the node in the normal way and put in a filter in the /spider/filter/spots directory to override the isolate. This filter can be very simple and consists of just one line ....

<P>Filters can be set for spots, announcements and WWV. You will find the directories for these under /spider/filter. You will find some example in the directories with the suffix <EM>.issue</EM>. There are two types of filter, one for incoming information and one for outgoing information. Outgoing filters are in the form <EM>CALLSIGN.pl</EM> and incoming filters are in the form <EM>in_CALLSIGN.pl</EM>. Filters can be set for both nodes and users.
<P>
<H2><A NAME="ss5.1">5.1 Spots</A>
</H2>
<P>All filters work in basically the same way. There are several elements delimited by commas. I will use the spot filter as an example ....
<P>
<P>The elements of the Spot filter are ....
<P>
<BLOCKQUOTE><CODE>
<PRE>
[action, field_no, sort, possible_values, hops]
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>There are 3 elements here to look at. Firstly, the action element. This is very simple and only 2 possible states exist, accept (1) or drop (0).
<P>
<P>The second element is the field_no. There are 13 possiblities to choose from here ....
<P>
<BLOCKQUOTE><CODE>
<PRE>
0 = frequency
1 = call
2 = date in unix format
3 = comment
4 = spotter
5 = spotted dxcc country
6 = spotter's dxcc country
7 = origin
8 = spotted itu
9 = spotted cq
10 = spotter's itu
11 = spotter's cq
12 = callsign of the channel on which the spot has appeared
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>The third element tells us what to expect in the fourth element. There are 4 possibilities ....
<P>
<BLOCKQUOTE><CODE>
<PRE>
n - numeric list of numbers e.g. [ 1,2,3 ]
r - ranges of pairs of numbers e.g. between 2 and 4 or 10 to 17 - [ 2,4, 10,17 ]
a - an alphanumeric regex
d - the default rule
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>The fifth element is simply the hops to set in this filter. This would only be used if the filter was for a node of course and overrides the hop count in hop_table.pl.
<P>
<P>So, let's look at an example spot filter. It does not matter in the example who the filter is to be used for.
So, what do we need in the filter? We need to filter the spots the user/node requires and also set a default rule for anything else outside the filter. Below is a simple filter that stops spots arriving from outside Europe.
<P>
<BLOCKQUOTE><CODE>
<PRE>
$in = [
[ 0, 4, 'a', '^(K|N|A|W|VE|VA|J)'], # 0 = drop, 'a' = alphanumeric
[ 1, 0, 'd', 0, 1 ], # 1 = want, 'd' = everything else
];
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>So the filter is wrapped in between a pair of square brackets. This tells Spider to look in between these limits. Then each line is contained within its own square brackets and ends with a comma.
Lets look carefully at the first line. The first element is 0 (drop). Therefore anything we put on this line will not be accepted. The next element is 4. This means we are filtering by the spotter. The third element is the letter "a" which tells the program to expect an alphanumeric expression in the fourth element. The fourth element is a list of letters separated by the pipe symbol.
<P>
<P>What this line does is tell the program to drop any spots posted by anyone in the USA, Canada or Japan.
<P>
<P>The second line is the default rule for anything else. The "d" tells us this and the line simply reads... accept anything else.
<P>
<P>You can add as many lines as you need to complete the filter but if there are several lines of the same type it is neater to enclose them all as one line. An example of this is where specific bands are set. We could write this like this ....
<P>
<BLOCKQUOTE><CODE>
<PRE>
[ 0,0,'r',[1800.0, 2000.0], 1],
[ 0,0,'r',[10100.0, 10150.0], 1],
[ 0,0,'r',[14000.0, 14350.0], 1],
[ 0,0,'r',[18000.0, 18200.0], 1],
</PRE>
</CODE></BLOCKQUOTE>
<P>
<P>But the line below achieves the same thing and is more efficient ....
<P>
<BLOCKQUOTE><CODE>
<PRE>
[
1800.0, 2000.0, # top band
10100.0, 10150.0, # WARC
14000.0, 14350.0, # 20m
18000.0, 18200.0, # WARC

<P>
<P>
<H2><A NAME="ss5.2">5.2 Announcements</A>
</H2>
<P>
<BLOCKQUOTE><CODE>
<PRE>
# This is an example announce or filter allowing only West EU announces
#
# The element list is:-
# 0 - callsign of announcer
# 1 - destination * = all, &lt;callsign> = routed to the node

</CODE></BLOCKQUOTE>
<P>In this example, only the prefixes listed will be allowed. It is possible to be quite specific. The Dutch prefix "P" is followed by several secondary identifiers which are allowed. So, in the example, "PA" or "PE" would be ok but not "PG". It is even possible to allow information from a single callsign. In the example this is DK0WCY, to allow the posting of his Aurora Beacon.

<P>It should be noted that the filter will start to be used only once a user/node has logged out and back in again.

<H2><A NAME="ss6.1">6.1 MOTD</A>
</H2>
<P>One of the more important things a cluster sysop needs to do is to get information to his users. The simplest way to do this is to have a banner that is sent to the user on login. This is know as a "message of the day" or "motd". To set this up, simply create a file in /spider/data called motd and edit it to say whatever you want. It is purely a text file and will be sent automatically to anyone logging in to the cluster.
<P>
<H2><A NAME="ss6.2">6.2 Downtime message</A>
</H2>
<P>If for any reason the cluster is down, maybe for upgrade or maintenance but the machine is still running, a message can be sent to the user advising them of the fact. This message lives in the /spider/data directory and is called "offline". Simply create the file and edit it to say whatever you wish. This file will be sent to a user attempting to log into the cluster when DXSpider is not actually running.
<P>
<H2><A NAME="ss6.3">6.3 Other text messages</A>
</H2>
<P>You can set other text messages to be read by the user if they input the file name. This could be for news items or maybe information for new users. To set this up, make a directory under /spider called <EM>packclus</EM>. Under this directory you can create files called <EM>news</EM> or <EM>newuser</EM> for example. In fact you can create files with any names you like. These can be listed by the user with the command ....
<P>
<BLOCKQUOTE><CODE>
<PRE>

</PRE>
</CODE></BLOCKQUOTE>
<P>They can be read by the user by typing the command ....
<P>
<BLOCKQUOTE><CODE>
<PRE>
type news
</PRE>
</CODE></BLOCKQUOTE>
<P>If the file they want to read is called <EM>news</EM>. You could also set an alias for this in the Alias file to allow them just to type <EM>news</EM>
<P>
<P>You can also store other information in this directory, either directly or nested under directories. One use for this would be to store DX bulletins such as the OPDX bulletins. These can be listed and read by the user. To keep things tidy, make a directory under /spider/packclus called <EM>bulletins</EM>. Now copy any OPDX or similar bulletins into it. These can be listed by the user in the same way as above using the <EM>show/files</EM> command with an extension for the bulletins directory you have just created, like this ....
<P>
<BLOCKQUOTE><CODE>

<P>You can create aliases for commands at will. Beware though, these may not always turn out as you think. Care is needed and you need to test the results once you have set an alias.

<H2><A NAME="ss6.5">6.5 Console.pl</A>
</H2>
<P>In later versions of Spider a simple console program is provided for the sysop. This has a type ahead buffer with line editing facilities and colour for spots, announces etc.
To use this program, simply use console.pl instead of client.pl.
<P>
<P>To edit the colours, copy /spider/perl/Console.pl to /spider/local and edit the file with your favourite editor.

<H2><A NAME="s7">7. Sysop commands</A></H2>
<P>Most maintenance tasks are automatic but there are some commands that are useful for a sysop. These are listed below in alphabetical order. The number in brackets following the command name is the permissions level needed to use the command.
<P>
<H2><A NAME="ss7.1">7.1 announce sysop (5)</A>
</H2>
<P><CODE><B>announce sysop &lt;text&gt;</B></CODE>
<P>
<P>Send an announcement to Sysops only
<P>
<H2><A NAME="ss7.2">7.2 connect (5) </A>
</H2>
<P><CODE><B>connect &lt;callsign&gt;</B> Start a connection to another DX Cluster</CODE>
<P>
<P>Start a connection process that will culminate in a new connection to the
DX cluster &lt;callsign&gt;. This process creates a new 'client' process which will
use the script in /spider/connect/&lt;callsign&gt; to effect the 'chat' exchange
necessary to traverse the network(s) to logon to the cluster &lt;callsign&gt;.
<P>
<P>
<H2><A NAME="ss7.3">7.3 catch (9) </A>
</H2>
<P><CODE><B>&lt;node_call&gt; All [&lt;msgno&gt; ...]</B> Mark a message as sent</CODE>
<P>
<P>When you send messages the fact that you have forwarded it to another node
is remembered so that it isn't sent again. When you have a new partner
node and you add their callsign to your /spider/msg/forward.pl file, all
outstanding non-private messages will be forwarded to them. This may well
be ALL the non-private messages. You can prevent this by using these
commmands:-
<P>catch GB7DJK all
catch GB7DJK 300 301 302 303
<P>and to undo what you have just done:-
<P>uncatch GB7DJK all
uncatch GB7DJK 300 301 302 303
<P>which will arrange for them to be forward candidates again.
<P>
<H2><A NAME="ss7.4">7.4 dbcreate (9)</A>
</H2>
<P><CODE><B>dbcreate &lt;name&gt;</B> Create a database entry<BR>
<B>dbcreate &lt;name&gt; chain &lt;name&gt; [&lt;name&gt;..]</B> Create a chained database entry<BR>
<B>dbcreate &lt;name&gt; remote &lt;node&gt;</B> Create a remote database entry<BR></CODE>
<P>
<P>DBCREATE allows you to define a database in the system. It doesn't actually
create anything, just defines it.
<P>The databases that are created are simple DB_File hash databases, they are
therefore already 'indexed'.
<P>You can define a local database with the first form of the command eg:
<P>DBCREATE oblast
<P>You can also chain databases with the addition of the 'chain' keyword.
This will search each database one after the other. A typical example
is:
<P>DBCREATE sdx_qsl chain sql_ad
<P>No checking is done to see if the any of the chained databases exist, in
fact it is usually better to do the above statement first then do each of
the chained databases.
<P>Databases can exist offsite. To define a database that lives on another
node do:
<P>DBCREATE buckmaster remote gb7dxc
<P>Remote databases cannot be chained; however, the last database in a
a chain can be a remote database eg:
<P>DBCREATE qsl chain gb7dxc
<P>To see what databases have been defined do:
<P>DBAVAIL (or it will have been aliased to SHOW/COMMAND)
<P>It would be normal for you to add an entry into your local Aliases file
to allow people to use the 'SHOW/&lt;dbname&gt;' style syntax. So you would
need to add a line like:-
<P>
<BLOCKQUOTE><CODE>
<PRE>
's' => [
..
..
'^sh\w*/buc', 'dbshow buckmaster', 'dbshow',
..
..
],
</PRE>
</CODE></BLOCKQUOTE>
<P>to allow
<P>SH/BUCK g1tlh
<P>to work as they may be used to.
<P>See DBIMPORT for the importing of existing AK1A format data to databases.
See DBSHOW for generic database enquiry
<P>
<H2><A NAME="ss7.5">7.5 dbimport (9)</A>
</H2>
<P><CODE><B>dbimport &lt;dbname&gt;</B> Import AK1A data into a database</CODE>
<P>
<P>If you want to import or update data in bulk to a database you can use
this command. It will either create or update entries into an existing
database. For example:-
<P>DBIMPORT oblast /tmp/OBLAST.FUL
<P>will import the standard OBLAST database that comes with AK1A into the
oblast database held locally.
<P>
<H2><A NAME="ss7.6">7.6 dbremove (9)</A>
</H2>
<P><CODE><B>dbremove &lt;dbname&gt;</B> Delete a database</CODE>
<P>
<P>DBREMOVE will completely remove a database entry and also delete any data
file that is associated with it.
<P>There is no warning, no comeback, no safety net.
<P>For example:
<P>DBREMOVE oblast
<P>will remove the oblast database from the system and it will also remove
the associated datafile.
<P>I repeat:
<P>There is no warning, no comeback, no safety net.
<P>You have been warned.
<P>
<H2><A NAME="ss7.7">7.7 debug (9)</A>
</H2>
<P><CODE><B>debug</B> Set the cluster program into debug mode</CODE>
<P>
<P>Executing this command will only have an effect if you are running the cluster
in debug mode i.e.
<P>
<BLOCKQUOTE><CODE>
<PRE>
perl -d cluster.pl
</PRE>
</CODE></BLOCKQUOTE>
<P>It will interrupt the cluster just after the debug command has finished.
<P>
<H2><A NAME="ss7.8">7.8 directory (5)</A>
</H2>
<P>Works just like the user command except that sysops can see ALL messages.
<P>
<H2><A NAME="ss7.9">7.9 disconnect (8)</A>
</H2>
<P><CODE><B>disconnect &lt;call&gt; [&lt;call&gt; ...]</B> Disconnect a user or node</CODE>
<P>
<P>Disconnect any &lt;call&gt; connected locally
<P>
<H2><A NAME="ss7.10">7.10 export (9)</A>
</H2>
<P><CODE><B>export &lt;msgno&gt; &lt;filename&gt;</B> Export a message to a file</CODE>
<P>
<P>Export a message to a file. This command can only be executed on a local
console with a fully privileged user. The file produced will be in a form
ready to be imported back into the cluster by placing it in the import
directory (/spider/msg/import).
<P>This command cannot overwrite an existing file. This is to provide some
measure of security. Any files written will owned by the same user as the
main cluster, otherwise you can put the new files anywhere the cluster can
access. For example:-
<P>EXPORT 2345 /tmp/a
<P>
<H2><A NAME="ss7.11">7.11 forward/opername (1)</A>
</H2>
<P><CODE><B>forward/opername &lt;call&gt;</B> Send out information on this &lt;call&gt; to all clusters</CODE>
<P>
<P>This command sends out any information held in the user file which can
be broadcast in PC41 protocol packets. This information is Name, QTH, Location
and Homenode. PC41s are only sent for the information that is available.
<P>
<H2><A NAME="ss7.12">7.12 init (5)</A>
</H2>
<P><CODE><B>init &lt;node call&gt;</B> Re-initialise a link to an AK1A compatible node</CODE>
<P>
<P>This command attempts to re-initialise a link to a (usually) AK1A node
that has got confused, usually by a protocol loop of some kind. It may
work - but you usually will be better off simply disconnecting it (or
better, if it is a real AK1A node, doing an RCMD &lt;node&gt; DISC/F &lt;your
node&gt;).
<P>Best of luck - you will need it.
<P>
<H2><A NAME="ss7.13">7.13 kill (5)</A>
</H2>
<P><CODE><B>kill &lt;msgno&gt; [&lt;msgno&gt; ...]</B> Remove or erase a message from the system<BR>
<B>kill from &lt;call&gt;</B> Remove all messages from a callsign<BR>
<B>kill to &lt;call&gt;</B> Remove all messages to a callsign<BR></CODE>
<P>
<P>You can get rid of any message to or originating from your callsign using
this command. You can remove more than one message at a time.
<P>As a sysop you can kill any message on the system.
<P>
<H2><A NAME="ss7.14">7.14 kill full (5)</A>
<CODE><B>kill full &lt;msgno&gt; [&lt;msgno&gt;]</B> Delete a message from the whole cluster</CODE></H2>
<P>Delete a message (usually a 'bulletin') from the whole cluster system.
<P>This uses the subject field, so any messages that have exactly the same subject
will be deleted. Beware!
<P>
<H2><A NAME="ss7.15">7.15 load/aliases (9)</A>
</H2>
<P><CODE><B>load/aliases</B> Reload the command alias table</CODE>
<P>
<P>Reload the /spider/cmd/Aliases file after you have editted it. You will need to
do this if you change this file whilst the cluster is running in order for the
changes to take effect.
<P>
<H2><A NAME="ss7.16">7.16 load/bands (9)</A>
</H2>
<P><CODE><B>load/bands</B> Reload the band limits table</CODE>
<P>
<P>Reload the /spider/data/bands.pl file if you have changed it manually whilst
the cluster is running.
<P>
<H2><A NAME="ss7.17">7.17 load/cmd_cache (9)</A>
</H2>
<P><CODE><B>load/cmd_cache</B> Reload the automatic command cache</CODE>
<P>
<P>Normally, if you change a command file in the cmd or local_cmd tree it will
automatially be picked up by the cluster program. Sometimes it can get confused
if you are doing a lot of moving commands about or delete a command in the
local_cmd tree and want to use the normal one again. Execute this command to
reset everything back to the state it was just after a cluster restart.
<P>
<H2><A NAME="ss7.18">7.18 load/messages (9)</A>
</H2>
<P><CODE><B>load/messages</B> Reload the system messages file</CODE>
<P>
<P>If you change the /spider/perl/Messages file (usually whilst fiddling/writing ne
commands) you can have them take effect during a cluster session by executing this
command. You need to do this if get something like :-
<P>unknown message 'xxxx' in lang 'en'
<P>
<H2><A NAME="ss7.19">7.19 load/prefixes (9)</A>
</H2>
<P><CODE><B>load/prefixes</B> Reload the prefix table</CODE>
<P>
<P>Reload the /spider/data/prefix_data.pl file if you have changed it manually whilst
the cluster is running.
<P>
<H2><A NAME="ss7.20">7.20 merge (5)</A>
</H2>
<P><CODE><B>merge &lt;node&gt; [&lt;no spots&gt;/&lt;no wwv&gt;]</B> Ask for the latest spots and WWV</CODE>
<P>
<P>MERGE allows you to bring your spot and wwv database up to date. By default
it will request the last 10 spots and 5 WWVs from the node you select. The
node must be connected locally.
<P>You can request any number of spots or wwv and although they will be appended
to your databases they will not duplicate any that have recently been added
(the last 2 days for spots and last month for WWV data).
<P>
<H2><A NAME="ss7.21">7.21 msg (9)</A>
</H2>
<P><CODE><B>msg &lt;cmd&gt; &lt;msgno&gt; [data ...]</B> Alter various message parameters</CODE>
<P>
<P>Alter message parameters like To, From, Subject, whether private or bulletin
or return receipt (RR) is required or whether to keep this message from timing
out.
<P>
<BLOCKQUOTE><CODE>
<PRE>
MSG TO &lt;msgno> &lt;call> - change TO callsign to &lt;call>
MSG FRom &lt;msgno> &lt;call> - change FROM callsign to &lt;call>

<P>You can look at the status of a message by using:-
<P>STAT/MSG &lt;msgno&gt;
<P>This will display more information on the message than DIR does.
<P>
<H2><A NAME="ss7.22">7.22 pc (8)</A>
</H2>
<P><CODE><B>pc &lt;call&gt; &lt;text&gt;</B> Send text (eg PC Protocol) to &lt;call&gt;</CODE>
<P>
<P>Send some arbitrary text to a locally connected callsign. No processing is done on
the text. This command allows you to send PC Protocol to unstick things if problems
arise (messages get stuck etc). eg:-
<P>pc gb7djk PC33^GB7TLH^GB7DJK^400^
<P>You can also use in the same way as a talk command to a connected user but
without any processing, added of "from &lt;blah&gt; to &lt;blah&gt;" or whatever.
<P>pc G1TLH Try doing that properly!!!
<P>
<H2><A NAME="ss7.23">7.23 ping (1)</A>
</H2>
<P><CODE><B>ping &lt;node&gt;</B> Send a ping command to another cluster node</CODE>
<P>
<P>This command is used to estimate the quality of the link to another cluster.
The time returned is the length of time taken for a PC51 to go to another
cluster and be returned.
<P>Any visible cluster node can be PINGed.
<P>
<H2><A NAME="ss7.24">7.24 rcmd (1)</A>
</H2>
<P><CODE><B>rcmd &lt;node call&gt; &lt;cmd&gt;</B> Send a command to another DX cluster</CODE>
<P>
<P>This command allows you to send nearly any command to another DX Cluster
node that is connected to the system.
<P>Whether you get any output is dependant on a) whether the other system knows
that the node callsign of this cluster is in fact a node b) whether the
other system is allowing RCMDs from this node and c) whether you have
permission to send this command at all.
<P>
<H2><A NAME="ss7.25">7.25 read (5)</A>
</H2>
<P><CODE><B>read &lt;msgno&gt;</B> Read a message on the system</CODE>
<P>
<P>As a sysop you may read any message on the system
<P>
<H2><A NAME="ss7.26">7.26 set/debug (9)</A>
</H2>
<P><CODE><B>set/debug &lt;name&gt;</B>Add a debug level to the debug set</CODE>
<P>
<P>You can remove this level with unset/debug &lt;name&gt;
<P>
<H2><A NAME="ss7.27">7.27 set/isolate (9)</A>
</H2>
<P><CODE><B>set/isolate &lt;node call&gt;</B> Isolate a node from the rest of the network</CODE>
<P>
<P>Connect a node to your system in such a way that you are a full protocol
member of its network and can see all spots on it, but nothing either leaks
out from it nor goes back into from the rest of the nodes connected to you.
<P>You can potentially connect several nodes in this way.
<P>You can see which nodes are isolated with the show/isolate (1) command.
<P>You can remove the isolation with the command unset/isolate.
<P>
<H2><A NAME="ss7.28">7.28 set/sys_location (9)</A>
</H2>
<P><CODE><B>set/sys_location &lt;lat &amp; long&gt;</B>Set your cluster latitude and longitude</CODE>
<P>
<P>In order to get accurate headings and such like you must tell the system
what your latitude and longitude is. If you have not yet done a SET/QRA
then this command will set your QRA locator for you. For example:-
<P>SET/LOCATION 52 22 N 0 57 E
<P>
<H2><A NAME="ss7.29">7.29 set/lockout (9)</A>
</H2>
<P><CODE><B>set/lockout &lt;call&gt;</B>Stop a callsign connecting to the cluster</CODE>
<P>
<P>You can show who is locked out with the show/lockout (9) command.
<P>To allow the user to connect again, use the command unset/lockout
<P>
<H2><A NAME="ss7.30">7.30 set/node (9)</A>
</H2>
<P><CODE><B>set/node &lt;call&gt; [&lt;call&gt; ...]</B>Make the callsign an AK1A cluster</CODE>
<P>
<P>Tell the system that the call(s) are to be treated as AK1A cluster and
fed PC Protocol rather normal user commands.
<P>From version 1.41 you can also set the following types of cluster
<P>
<PRE>
set/spider
set/dxnet
set/clx
set/arcluster
</PRE>
<P>To see what your nodes are set to, use the show/nodes command.
<P>
<H2><A NAME="ss7.31">7.31 set/obscount (9)</A>
</H2>
<P><CODE><B>set/obscount &lt;count&gt; &lt;node call&gt;</B> Set the 'pump-up' obscelence counter</CODE>
<P>
<P>From version 1.35 onwards neighbouring nodes are pinged at regular intervals (see
SET/PINGINTERVAL), usually 300 seconds or 5 minutes. There is a 'pump-up'
counter which is decremented on every outgoing ping and then reset to
the 'obscount' value on every incoming ping. The default value of this
parameter is 2.
<P>What this means is that a neighbouring node will be pinged twice at
(default) 300 second intervals and if no reply has been heard just before
what would be the third attempt, that node is disconnected.
<P>If a ping is heard then the obscount is reset to the full value. Using
default values, if a node has not responded to a ping within 15 minutes,
it is disconnected.
<P>
<H2><A NAME="ss7.32">7.32 set/pinginterval (9)</A>
</H2>
<P><CODE><B>set/pinginterval &lt;time&gt; &lt;node call&gt;</B> Set the ping time to neighbouring nodes</CODE>
<P>
<P>As from version 1.35 all neighbouring nodes are pinged at regular intervals
in order to determine the rolling quality of the link and, in future, to
affect routing decisions. The default interval is 300 secs or 5 minutes.
<P>You can use this command to set a different interval. Please don't.
<P>But if you do the value you enter is treated as minutes up 60 and seconds
for numbers greater than that.
<P>This is used also to help determine when a link is down at the far end
(as certain cluster software doesn't always notice), see SET/OBSCOUNT
for more information.
<P>
<H2><A NAME="ss7.33">7.33 set/privilege (9)</A>
</H2>
<P><CODE><B>set/privilege &lt;n&gt; &lt;call&gt; [&lt;call&gt; ...]</B> Set the privilege level on a call</CODE>
<P>
<P>Set the privilege level on a callsign. The privilege levels that pertain
to commands are as default:-
<P>
<BLOCKQUOTE><CODE>
<PRE>
0 - normal user
1 - allow remote nodes normal user RCMDs
5 - various privileged commands (including shutdown, but not disc-
connect), the normal level for another node.
8 - more privileged commands (including disconnect)
9 - local sysop privilege. DO NOT SET ANY REMOTE USER OR NODE TO THIS
LEVEL.
</PRE>
</CODE></BLOCKQUOTE>
<P>If you are a sysop and you come in as a normal user on a remote connection
your privilege will automatically be set to 0.
<P>
<H2><A NAME="ss7.34">7.34 set/password (9)</A>
</H2>
<P><CODE><B>set/password &lt;callsign&gt; &lt;string&gt;</B> Set a users password</CODE>
<P>
<P>The password for a user can only be set by a full sysop. The string
can contain any characters but any spaces are removed (you can type in
spaces - but they won't appear in the password). You can see the
result with STAT/USER. The password is the usual 30 character baycom
type password.
<P>
<H2><A NAME="ss7.35">7.35 set/sys_qra (9)</A>
</H2>
<P><CODE><B>set/sys_qra &lt;locator&gt;</B> Set your cluster QRA locator</CODE>
<P>
<H2><A NAME="ss7.36">7.36 show program (5)</A>
</H2>
<P><CODE><B>show/program</B> Show the locations of all the included program modules</CODE>
<P>
<P>Show the name and location where every program module was load from. This
is useful for checking where you think you have loaded a .pm file from.
<P>
<H2><A NAME="ss7.37">7.37 shutdown (5)</A>
</H2>
<P><CODE><B>shutdown</B>Shutdown the cluster</CODE>
<P>
<P>Shutdown the cluster and disconnect all the users. If you have Spider
set to respawn in /etc/inittab it will of course restart.
<P>
<H2><A NAME="ss7.38">7.38 stat/db (5)</A>
</H2>
<P><CODE><B>stat/db &lt;dbname&gt;</B> Show the status of a database</CODE>
<P>
<P>Show the internal status of a database descriptor.
<P>Depending on your privilege level you will see more or less information.
This command is unlikely to be of much use to anyone other than a sysop.
<P>
<H2><A NAME="ss7.39">7.39 stat/channel (5)</A>
</H2>
<P><CODE><B>stat/channel &lt;callsign&gt;</B> Show the status of a channel on the cluster</CODE>
<P>
<P>Show the internal status of the channel object either for the channel that
you are on or else for the callsign that you asked for.
<P>Only the fields that are defined (in perl term) will be displayed.
<P>
<H2><A NAME="ss7.40">7.40 stat/msg (5)</A>
</H2>
<P><CODE><B>stat/msg &lt;msgno&gt;</B> Show the status of a message</CODE>
<P>
<P>This command shows the internal status of a message and includes information
such as to whom it has been forwarded, its size, origin etc etc.
<P>
<H2><A NAME="ss7.41">7.41 stat/user (5)</A>
</H2>
<P><CODE><B>stat/user &lt;callsign&gt;</B> Show the full status of a user</CODE>
<P>
<P>Shows the full contents of a user record including all the secret flags
and stuff.
<P>Only the fields that are defined (in perl term) will be displayed.
