From version 1.49 DXSpider has some additional security features. These -are not by any means meant to be exhaustive, however they do afford some -security against piracy. These two new features can be used independently -of each other or in concert to tighten the security. -
-
From version 1.50, you can use the freeware software MRTG to produce +really nice graphical statistics on your web site. For an example +try +http://www.gb7mbc.net/mrtg/stats.html.
+ +The following should help you get it all working.
-The basic principle of registration is simple. If a user is not registered -by the sysop, then they have read-only access to the cluster. The only -thing they can actually send is a talk or a message to the sysop. In -order for them to be able to spot, send announces or talks etc the sysop -must register them with the set/register command, like this ... +
First you need to download the latest version of MRTG from +http://people.ee.ethz.ch/~oetiker/webtools/mrtg/. +You will also need the following files..
-set/register g0vgs
+libpng-1.0.14.tar.gz
+zlib-1.1.4.tar.gz
+gd-1.8.3.tar.gz
The user g0vgs can now fully use the cluster. In order to enable -registration, you can issue the command ... +
+Login to your machine as the root user, put all the downloaded files +in /usr/local/src/ (or wherever you prefer) and untar and compile them. +All the information to compile and install these sources come with them. +After compilation and installation, you will find MRTG in /usr/local/mrtg-2.
+ +Now copy all the files in /usr/local/src/mrtg-2.9.22/images/ to +/spider/html/mrtg/
+ +You now need to make 2 symbolic links like below...
-set/var $main::reqreg = 1
+ln -s /usr/local/mrtg-2/bin/mrtg /usr/bin/mrtg
+ln -s /usr/local/mrtg-2/lib/mrtg2 /usr/lib/mrtg2
Any users that are not registered will now see the motd_nor file rather -than the motd file as discussed in the Information, files and useful -programs section. -
-
Entering this line at the prompt will only last for the time the cluster -is running of course and would not be present on a restart. To make the -change permanent, add the above line to /spider/scripts/startup. To -read more on the startup file, see the section on Information, files -and useful programs. -
-
To unregister a user use unset/register and to show the list -of registered users, use the command show/register. -
-
Now login to the cluster as your sysop user and run the command +"mrtg all".
-At the moment, passwords only affect users who login to a DXSpider -cluster node via telnet. If a user requires a password, they can -either set it themselves or have the sysop enter it for them by using -the set/password command. Any users who already have passwords, -such as remote sysops, will be asked for their passwords automatically -by the cluster. Using passwords in this way means that the user has a -choice on whether to have a password or not. To force the use of -passwords at login, issue the command ... +
Now you are nearly there! Login as the sysop user and change to the +/spider/html/mrtg/ directory. Now run the command indexmaker as +shown below...
-set/var $main::passwdreq = 1
+indexmaker --output stats.html --columns=1 --title "MRTG statistics for GB7DJK" ../../mrtg/mrtg.cfg
at the cluster prompt. This can also be added to the /spider/scripts/startup -file as above to make the change permanent. +
+Changing the callsign for your own cluster callsign of course!
+ +And finally you need to login as the root user and create one last +symbolic link. Where this points will depend on where your html +documents are kept. For RedHat systems you use...
-
Of course, if you do this you will have to assign a password for each of -your users. If you were asking them to register, it is anticipated that -you would ask them to send you a message both to ask to be registered and -to give you the password they wish to use. +
+
+ln -s /home/sysop/spider/html/mrtg /home/httpd/html/mrtg
+
+and for SuSE systems...
-
Should a user forget their password, it can be reset by the sysop by -first removing the existing password and then setting a new one like so ... +
+
+ln -s /home/sysop/spider/html/mrtg /usr/local/httpd/htdocs/mrtg
+
+If you now point your browser to your website as below it should all +be happening!
-unset/password g0vgs
-set/password g0vgs new_password
+http://www.xxx.xxx/mrtg/stats.html
Of course, to get the stats to update, you need to add some information +in the spider crontab file as below...
+
+
+# Update stats for mrtg on website
+00,05,10,15,20,25,30,35,40,45,50,55 * * * * run_cmd('mrtg all')
+
+This will update the site every 5 minutes.
