- -Upto v1.44 it was not possible for the user to set their own filters. From -v1.45 though that has all changed. It is now possible to set filters for just -about anything you wish. If you have just updated from an older version of -DXSpider you will need to update your new filters. You do not need to do -anything with your old filters, they will be renamed as you update. -
-
There are 3 basic commands involved in setting and manipulating filters. These -are accept, reject and clear. First we will look -generally at filtering. There are a number of things you can filter in the -DXSpider system. They all use the same general mechanism. -
-
In general terms you can create a 'reject' or an 'accept' filter which can have -up to 10 lines in it. You do this using, for example ... -
-
-
-
-accept/spots .....
-reject/spots .....
-
-
-where ..... are the specific commands for that type of filter. There are filters -for spots, wwv, announce, wcy and (for sysops) connects. See each different -accept or reject command reference for more details. -
There is also a command to clear out one or more lines in a filter. They are ... +
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.
+ +This message of the day file lives in the same directory as the standard +motd file but is only sent to non-registered users. Once registered they +will receive the same message as any other user.
+ +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.
+ +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 packclus. +Under this directory you can create files called news or newuser +for example. In fact you can create files with any names you like. These can +be listed by the user with the command ....
-clear/spots 1
-clear/spots all
+show/files
-There is clear/xxxx command for each type of filter. -
-
and you can check that your filters have worked by the command ... +
+They can be read by the user by typing the command ....
-
-show/filter
+type news
--
For now we are going to use spots for the examples, but you can apply the same -principles to all types of filter. -
-
If the file they want to read is called news. You could also set +an alias for this in the Alias file to allow them just to type news
-There are two main types of filter, accept or reject. You -can use either to achieve the result you want dependent on your own preference -and which is more simple to do. It is pointless writing 8 lines of reject -filters when 1 accept filter would do the same thing! Each filter has 10 -lines (of any length) which are tried in order. If a line matches then the -action you have specified is taken (ie reject means ignore it and accept -means take it) -
-
If you specify reject filters, then any lines that arrive that match the filter -will be dumped but all else will be accepted. If you use an accept filter, -then ONLY the lines in the filter will be accepted and all else will be dumped. -For example if you have a single line accept filter ... +
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 +bulletin. Now copy any OPDX or similar bulletins into it. These +can be listed by the user in the same way as above using the show/files +command with an extension for the bulletin directory you have just created, +like this ....
-accept/spots on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
+show/files bulletin
-then you will ONLY get VHF spots from or to CQ zones -14, 15 and 16. -
-
If you set a reject filter like this ... +
+ +An example would look like this ....
-reject/spots on hf/cw
+sh/files
+bulletin DIR 20-Dec-1999 1715Z news 1602 14-Dec-1999 1330Z
-Then you will get everything EXCEPT HF CW spots. You could make this -single filter even more flexible. For example, if you are interested in IOTA -and will work it even on CW even though normally you are not interested in -CW, then you could say ... +
+You can see that in the files area (basically the packclus directory) there is a +file called news and a directory called bulletin. You can +also see that dates they were created. In the case of the file news, +you can also see the time it was last modified, a good clue as to whether the +file has been updated since you last read it. To read the file called +news you would simply issue the command ....
-reject/spots on hf/cw and not info iota
+type news
-But in that case you might only be interested in iota and say:- +
+To look what is in the bulletin directory you issue the command ....
-accept/spots not on hf/cw or info iota
+show/files bulletin

-which achieves exactly the same thing. You should choose one or the other -until you are comfortable with the way it works. You can mix them if you -wish (actually you can have an accept AND a reject on the same line) but -don't attempt this until you are sure you know what you are doing! -

-What this does is to ignore all HF CW spots and also rejects any spots on VHF -which don't either originate or spot someone in Europe. -
-
This is an example where you would use a line number (1 and 2 in this case), if -you leave the digit out, the system assumes '1'. Digits '0'-'9' are available. -This make it easier to see just what filters you have set. It also makes it -more simple to remove individual filters, during a contest for example. -
-
You will notice in the above example that the second line has brackets. Look -at the line logically. You can see there are 2 separate sections to it. We -are saying reject spots that are VHF or above APART from those in -zones 14, 15 and 16 (either spotted there or originated there). If you did -not have the brackets to separate the 2 sections, then Spider would read it -logically from the front and see a different expression entirely ... +
+The page length will of course depend on what you have it set to!
+ +You will find a file in /spider/cmd/ called Aliases. This is the file that +controls what a user gets when issuing a command. It is also possible to +create your own aliases for databases and files you create locally.
+ +You should not alter the original file in /spider/cmd/ but create a new file +with the same name in /spider/local_cmd. This means that any new Aliases files +that is downloaded will not overwrite your self created Aliases and also that +you do not override any new Aliases with your copy in /spider/local_cmd/. You +must remember that any files you store in /spider/local/ or /spider/local_cmd +override the originals if the same lines are used in both files.
+ +The best way of dealing with all this then is to only put your own locally +created Aliases in the copy in /spider/local_cmd. The example below is +currently in use at GB7MBC.
-(on 50000/1400000 and by_zone 14,15,16) or call_zone 14,15,16
+
+#
+# Local Aliases File
+#
+
+package CmdAlias;
+
+%alias = (
+ 'n' => [
+ '^news$', 'type news', 'type',
+ ],
+ 's' => [
+ '^sh\w*/buck$', 'show/qrz', 'show',
+ '^sh\w*/hftest$', 'dbshow hftest', 'dbshow',
+ '^sh\w*/qsl$', 'dbshow qsl', 'dbshow',
+ '^sh\w*/vhf$', 'dbshow vhf', 'dbshow',
+ '^sh\w*/vhftest$', 'dbshow vhftest', 'dbshow',
+ ],
+)
-The simple way to remember this is, if you use OR - use brackets. Whilst we are -here CASE is not important. 'And BY_Zone' is just the same as 'and by_zone'. -
As mentioned earlier, setting several filters can be more flexible than -simply setting one complex one. Doing it in this way means that if you want -to alter your filter you can just redefine or remove one or more lines of it or -one line. For example ... +
+ +Each alphabetical section should be preceded by the initial letter and the section +should be wrapped in square brackets as you can see. The syntax is straightforward. +The first section on each line is the new command that will be allowed once the +alias is included. The second section is the command it is replacing and the last +section is the actual command that is being used.
+ +The eagle-eyed amongst you will have noticed that in the first section, the new +alias command has a '^' at the start and a '$' at the end. Basically these force +a perfect match on the alias. The '^' says match the beginning exactly and the +'$' says match the end exactly. This prevents unwanted and unintentional matches +with similar commands.
+ +I have 3 different types of alias in this file. At the top is an alias for 'news'. +This is a file I have created in the /spider/packclus/ directory where I can inform +users of new developments or points of interest. In it's initial form a user would +have to use the command type news. The alias allows them to simply type +news to get the info. Second is an alias for the show/qrz +command so that those users used to the original show/buck command in +AK1A will not get an error, and the rest of the lines are for locally created +databases so that a user can type show/hftest instead of having to use +the command dbshow hftest which is not as intuitive.
+ +This file is just an example and you should edit it to your own requirements. +Once created, simply issue the command load/alias at the cluster +prompt as the sysop user and the aliases should be available.
+ + +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.
+ +To edit the colours, copy /spider/perl/Console.pl to /spider/local and edit the +file with your favourite editor.
+ +Spider has a powerful and flexible show/satellite command. In order for +this to be accurate, the kepler data has to be updated regularly. In +general, this data is available as an email or via cluster mail. +Updating it is simple. First you need to export the mail message as a +file. You do this with the export command from the cluster prompt +as the sysop. For example ...
-reject/spots 1 on hf/ssb
+export 5467 /spider/perl/keps.in
-would redefine our earlier example, or +
+ +would export message number 5467 as a file called keps.in in the +/spider/perl directory.
+ +Now login to a VT as sysop and cd /spider/perl. There is a command in +the perl directory called convkeps.pl. All we need to do now is +convert the file like so ...
-clear/spots 1
+./convkeps.pl keps.in
-To remove all the filter lines in the spot filter ... +
+ +Now go back to the cluster and issue the command ...
-clear/spots all
+load/keps
--
You can filter in several different ways. The options are listed in the -various helpfiles for accept, reject and filter. -
-
That is it! the kepler data has been updated.
+ +Sometimes all that is needed is a general rule for node connects. This can -be done with a node_default filter. This rule will always be followed, even -if the link is isolated, unless another filter is set specifically. Default -rules can be set for nodes and users. They can be set for spots, announces, -WWV and WCY. They can also be used for hops. An example might look like -this ... -
-
-
-accept/spot node_default by_zone 14,15,16,20,33
-set/hops node_default spot 50
-
-
-This filter is for spots only, you could set others for announce, WWV and WCY. -This filter would work for ALL nodes unless a specific filter is written to -override it for a particular node. You can also set a user_default should -you require. It is important to note that default filters should be -considered to be "connected". By this I mean that should you override the -default filter for spots, you need to add a rule for the hops for spots also. -
-
The command sh/qrz will only work once you have followed a few +simple steps. First you need to get a user ID and password from qrz.com. +Simply go to the site and create one. Secondly you need to copy the file +/spider/perl/Internet.pm to /spider/local and alter it to match your user +ID and password. You also at this point need to set $allow=1 to complete +the setup. Many thanks to Fred Lloyd, the proprieter of +qrz.com for allowing this access.
+ +Once you are happy with the results you get, you may like to experiment. -
-
The previous example that filters hf/cw spots and accepts vhf/uhf spots from EU -can be written with a mixed filter, for example ... +
There appear to be very few logging programs out there that support telnet +especially the popular ones like LogEQF, Turbolog etc. This can make it +difficult to connect to your own cluster! +The way to do it is to make the logging program think it has a TNC attached +to a com port on the logging PC and 'push' a linux login out to it. +This is achieved very simply by the use of agetty.
+ +All that is required is to add a line in /etc/inittab to have the client +ready for a connection on the com port of your choice. Remember that in +Linux, the com ports start at ttyS0 for com1, ttyS1 for com2 etc.
-rej/spot on hf/cw
-acc/spot on 0/30000
-acc/spot 2 on 50000/1400000 and (by_zone 14,15,16 or call_zone 14,15,16)
+c4:2345:respawn:/sbin/agetty -L 9600 ttyS1
-Note that the first filter has not been specified with a number. This will -automatically be assumed to be number 1. In this case, we have said reject all -HF spots in the CW section of the bands but accept all others at HF. Also -accept anything in VHF and above spotted in or by operators in the zones -14, 15 and 16. Each filter slot actually has a 'reject' slot and -an 'accept' slot. The reject slot is executed BEFORE the accept slot. -
-
It was mentioned earlier that after a reject test that doesn't match, the default -for following tests is 'accept', the reverse is true for 'accept'. In the example -what happens is that the reject is executed first, any non hf/cw spot is passed -to the accept line, which lets through everything else on HF. The next filter line -lets through just VHF/UHF spots from EU. -
-
+
+ +Add this after the standard runlevel lines in /etc/inittab. The above +line works on ttyS1 (com2). Now as root, issue the command telinit q +and it should be ready for connection. All that is required is a 3 wire +serial lead (tx, rx and signal ground). Tell you logging program to use +8n1 at 9600 baud and you should see a Linux login prompt. Login as normal +and then telnet from there to the cluster.
+
