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). +
From 1.48 onwards it will become increasingly possible to control DXSpider's +operation with scripts of various kinds.
-
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 ... -
-
-
-#
-# 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,
- 19 => 8,
- 21 => 8,
- },
-
- GB7UDX => { 11 => 8,
- 12 => 8,
- 16 => 8,
- 17 => 8,
- 19 => 8,
- 21 => 8,
- },
- GB7BAA => {
- 11 => 5,
- 12 => 8,
- 16 => 8,
- 17 => 8,
- 19 => 8,
- 21 => 8,
- },
-};

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. +
In the first instance, in 1.48, the sysop can create, with their favorite +text editor, files in the directory /spider/scripts which contain +any legal command for a callsign or class of connection which will be executed +at logon.
-
You can alter this file at any time, including whilst the cluster is running. If you alter the file during runtime, -the command load/hops will bring your changes into effect. +
+The filename are the callsign of the connection that you want the script to +operate on, eg: /spider/scripts/g1tlh. The filenames are always in +lower case on those architectures where this makes a difference.
-
It is possible to isolate networks from each other on a "gateway" node using the -set/isolate <node_call> command. -
-
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. -
-
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. -
-
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 .... +
In addition to the callsign specific scripts there are three others:-
-$in = [
- [ 1, 0, 'd', 0, 3] # The last figure (3) is the hop count
-];
+startup
+user_default
+node_default
The startup script is executed immediately after all +initialisation of the node is done, but before any connections are +possible. +
+
The user_default script is executed for every user that does +NOT already have a specific script. +
+
The node_default script is executed for every node that doesn't +have a specific script.
-
There is a lot more on filtering in the next section. +
There are a couple of examples in the /spider/scripts directory.
