+Using Dilimesh
+--------------
+
+1/ Point your browser at http://server/dilimesh/dilimesh/html
+
+2/ Set "Visualisation Server IP" on RHS and reload page.
+
+3/ Dilimesh will find new nodes automatically. Drag bouncing nodes
+ to the correct position on map.
+
+4/ Mouse over or click on a node to get IP and packet loss. If nodes
+ are running signal strength daemon signal strengths of adjacent
+ nodes will also be displayed.
+
+5/ Click on links to get "Distance" stats on lower right hand side.
+
+5/ Node colours:
+ * blue - packet loss < 10%
+ * red - packet loss between 10% and 90%
+ * black - packet loss > 90%
+
+5/ "Update Enable" will update packet loss, network links and signal
+ strength automatically.
Status
------
* Alpha
-* Tested on Firefox 3.5.3 with Apache2 server
+* Tested on Firefox 3.5.3 with Apache2 servers running Ubuntu 9 & 10.
* Tested on small 5 node mesh network, might needs tweaks (e.g. fping
arguments) for larger networks
-* Displays nodes, link paths, node IP and packet loss
-* Signal strength per link feature under development
Implementation Notes
may already be running on your supernode. Batman on each node should
be configured for the vis server (e.g. -s 10.130.1.1)
-4/ A route from the web server PC to the mesh network.
+4/ A route from the web server PC to the mesh network. On the Ubuntu
+ machine I use as a server I put this script in the file
+ /etc/network/if-up.d/potato:
+
+ !/bin/sh
+ # Add interface and routes to connect to potato mesh network
+
+ ifconfig eth0 10.30.1.3 netmask 255.255.255.0
+ route add -net 10.130.1.0/24 gw 10.30.1.1
+ This file runs when the machine boots and connects to the Supernode
+ via Ethernet.
Installation
------------
1/ Server PC
- # sudo mkdir /var/www/dilimesh
- # sudo chmod 777 /var/www/dilimesh
- # cp dilimesh/* /var/www/dilimesh
- # cp cgi-bin/* /usr/lib/cgi-bin
+ $ svn co https://freetel.svn.sourceforge.net/svnroot/freetel/dilimesh

+ $ sudo cp cgi-bin/* /usr/lib/cgi-bin
2/ Supernode
$ ssh root@10.130.1.36 '/etc/rc.d/S99sigstr'
- Test if deamon is running
+ Test if daemon is running
$ telnet 10.130.1.36 4950

Debugging
---------
$ tail -f /var/log/apache2/access.log
-2/ Use Firebug on Firefox.
+2/ Use Firebug on Firefox to single step, set breakpoints etc.
3/ Check nodes.txt database, each line is (lat, lng, IP):
-34.87893842193011,138.55278968811035,10.130.1.23
