-This section describes the installation of DX Spider v1.46 on a
-
-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
- In addition to the standard Red Hat distribution you will require the
-following modules from
-
-
-Do get the latest versions of these packages and install them
-but use the above list as the earliest versions usable.
-
-
-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
-1.46 for this section but of course you would use the latest version.
-
-
-Login as root and create a user to run the cluster under.
-
-Now set a password for the user ...
-
-
-Now to unpack the DX Spider distribution, set symbolic links and group
-permissions. Copy the tarball to /home/sysop and do the following.
-
-
-The next step is to set the permissions on the Spider directory tree and files ....
-
-
-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 ..
-
-
-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 ....
-
-
-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.
-
-
-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 ....
-
-
-Now type the following command which creates the basic user file with you as
-the sysop.
-
-
-We can now bring spider up for the first time and see if all is well or not!
-It should look something like this ...
-
-
-If all is well then login on another term or console as sysop and
-cd to /spider/src. Now issue the following command ...
-
-
-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 ....
-
-
-and both the cluster and the client should return to Linux prompts.
-
-
-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.
-
-
-
-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.
-
-
-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 ...
-
-
-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 ....
-
-
-This needs to be added above the standard services such as ftp, telnet etc.
-Once this is done, you need to restart inetd like this ....
-
- Now login as sysop and cd spider/src. You can test that spider
-is accepting telnet logins by issuing the following command ....
-
-
-Assuming all is well, then try a telnet from your linux console ....
-
-
-You should now get the login prompt and be able to login as before.
-
-
-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 ...
-
-
-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 ...
-
-
-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 ...
-
-
-You should get an initialisation string from DXSpider like this ...
-
-
-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:-
-
-
-
-
-Both these examples assume that everything is set up properly at the other end.
-You will find other examples in the /spider/examples directory.
-
-
-You start the connection, from within a sysop enabled cluster login, by typing
-in the word connect followed by a script name like this ....
-
-
-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
-
-In a script, this might look like ...
-
-
-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 8000, 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 ...
-
-
-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.
-
-
-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 ...
-
-
-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 ...
-
-
-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.
-
-
-So far so good, now to automate script connections...
-
-
-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)
-
-
-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.
