-<P>Filters can be set for spots, announcements and WWV. You will find the
-directories for these under /spider/filter. You will find some examples 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>
-<P>All filters work in basically the same way. There are several elements
-delimited by commas. There can be many lines in the filter and they are
-read from the top by the program. When writing a filter you need to think
-carefully about just what you want to achieve. You are either going to write
-a filter to <EM>accept</EM> or to <EM>reject</EM>. Think of a filter as
-having 2 main elements. For a reject filter, you would have a line or multiple
-lines rejecting the things you do not wish to receive and then a default line
-accepting everything else that is not included in the filter. Likewise, for an
-accept filter, you would have a line or multiple lines accepting the things you
-wish to receive and a default line rejecting everthing else.
-<P>
-<P>In the example below, a user requires a filter that would only return SSB spots
-posted in Europe on the HF bands. This is achieved by first rejecting the CW
-section of each HF band and rejecting all of VHF, UHF etc based on frequency.
-Secondly, a filter rule is set based on CQ zones to only accept spots posted in
-Europe. Lastly, a default filter rule is set to reject anything outside the filter.
+<P>CVS stands for "Concurrent Versions System" and the CVS for DXSpider is held
+at
+<A HREF="http://www.sourceforge.net">Sourceforge</A>. This means
+that it is possible to update your DXSpider installation to the latest
+sources by using a few simple commands.

+<P>THIS IS NOT FOR THE FAINT HEARTED!!! ONLY DO THIS IF YOU HAVE A TEST
+INSTALLATION OR ARE WILLING TO HAVE YOUR CLUSTER CRASH ON YOU!!!
+THIS MUST BE CONSIDERED AT LEAST BETA TESTING AND MAYBE EVEN ALPHA!!
+YOU HAVE BEEN WARNED!!!
<P>
-<P>The actual elements of each filter are described more fully in the following
-sections.
+<P>DID I MENTION..... ONLY DO THIS IF YOU ARE WILLING TO ACCEPT THE
+CONSEQUENCES!!!
<P>

-<P>The elements of the Spot filter are ....

-</PRE>
-</CODE></BLOCKQUOTE>
+<P>BEFORE YOU EVEN CONSIDER STARTING WITH THIS MAKE A BACKUP OF YOUR
+ENTIRE SPIDER TREE!!
<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>Assuming you are connected to the Internet, you need to login to the
+CVS repository and then update your Spider source. There are several
+steps which are listed below ...
<P>
-<P>The second element is the field_no. There are 13 possiblities to choose from
-here ....
+<P>First login as the user <EM>sysop</EM>. Next you need to connect to the CVS
+repository. You do this with the command below ...
<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

+<P>You will get a password prompt. Simply hit return here and your machine should
+return to a normal linux prompt.
<P>
-<P>The third element tells us what to expect in the fourth element. There are
-4 possibilities ....
+<P>What happens next depends on whether you have an existing installation that
+you want to update with the latest and greatest or whether you just want
+to see what is there and/or run it on a new machine for testing.
+<P>If you are installing Spider from CVS then change directory to /home/sysop
+<P>If you are wanting to update Spider then cd to /tmp

- 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

+<P>The next step will create a brand new 'spider' directory in your current
+directory.
<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
- ];
+cvs -z3 -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider co spider
</PRE>
-</CODE></BLOCKQUOTE>
+<P>This command is all on one line.
<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>Hopefully your screen should show you downloading files. The -z3 simply compresses
+the download to improve speed.
+When this has finished, you will have exactly the same as if you had untarred a full
+tarball PLUS some extra directories and files that CVS needs to do the magic that
+it does.
<P>
-<P>What this line does is tell the program to drop any spots posted by anyone in
-the USA, Canada or Japan.
+<P>Now if you are doing a new installation, that's it. Carry on as if you have
+just downloaded and untarred the lastest tarball.
<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>If you want to upgrade your current installation then do this ...

-<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>and your files will be updated. As above, remember to recompile the "C" client
+if it has been updated (CVS will tell you) and restart if any of the perl scripts
+have been altered or added, again, CVS will tell you.
<P>
-<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.
-<P>I am not going to spend any more time on these filters now as they will become
-more "comprehensive" in the near future.
+<P>You will find any changes documented in the /spider/Changes file.
