	~~== Click tutorials ==~~

	~~=== Original Tutorial 1: ===~~

	Build a packet reflector which reflects all IP packets on a specific interface. So for example if I get a "ping echo" on the interface - send a "ping echo" back to the originating host on this interface. This will cause the other side to send a "ping echo reply" - which our reflector will also send back. You will notice this will cause ping to show (DUP) messages because it's getting duplicate echo reply's. This is also a fun trick if a hacker is trying to port scan you - he will get port scanned back - and get really upset and then leave the world of hacking and do something useful with his life like compose melodies for the limited repertoire of ocarina music.

	*[[Solution for Original Tutorial 1]]

	~~=== Tutorial 1: ===~~

	~~Create a "hello world" program which sends the string "Goodbye world" from one host to another host using UDP/IP. You will need to create a sender on one host and a receiver on the other host~~
	* [[Solution for tutorial 1 - sender]]
	* [[Solution for tutorial 1 - receiver]]


	~~=== Tutorial 2: ===~~

	~~Improve on the program in tutorial 1 so that you can send and receive messages. Use an element handler to change the message to be sent.~~

	~~=== Tutorial 3: ===~~

	Create a new element and packet structure which makes it possible to broadcast a list of beacons that were discovered on one node to all nodes within broadcast range of that node. You only need to send the ssid, channel and rssi for each discovered beacon.

	* Note: You don't need to encapsulate the packet in IP - you can send it using just your packet structure and assume that a click capable node will receive the packet.

	==Operating Systems==		==Operating Systems==
	The lab has been designed so that it is possible to network boot every node off a single server. This allows us to easily change the software running on the clients right down to the operating system level. The server runs on FreeBSD and ~~the first operating system that was~~ used on the clients was also FreeBSD. The OLSR mesh routing protocol was also implemented on the FreeBSD enabled clients to test the concept. Since many of the routing protocols have been implemented in Linux rather than other OS's, the next step was to attempt [[Linux netbooting]].		The lab has been designed so that it is possible to network boot every node off a single server. This allows us to easily change the software running on the clients right down to the operating system level. The server runs on Linux but there is also an old legacy FreeBSD server that is still running and can be used.

	~~==Getting protocols compiled for the massive mesh==~~

	~~'''HSLS'''~~		== Workshop notes from workshop held in August 2009 ==

	~~HSLS was compiled for NetBSD but a partial port to Linux was done by Proveen Gurung at Telecordia~~. ~~We recived~~ the ~~code and after some tweaks manged to get it running under linux~~. The ~~key changes are to edit the /etc/services file before running the deamon.~~		* [[Media:Lab_workshop_day1.pdf‎\|'''Day 1 of workshop: Learning the lab tools''']]

	~~The file should have the following entries added:~~		== Click tutorials ==

	:~~etx 9090/udp~~		=== Original Tutorial 1: ===
	~~:hsls 9191/udp~~
	~~:hslsapi 9292/tcp~~
	~~:nodeinfo 500/tcp~~

	~~Once~~ this is ~~done~~ you ~~can run the run_hsls script provided~~ - ~~just change~~ the ~~name~~ of the ~~wireless interface in the script~~.		Build a packet reflector which reflects all IP packets on a specific interface. So for example if I get a "ping echo" on the interface - send a "ping echo" back to the originating host on this interface. This will cause the other side to send a "ping echo reply" - which our reflector will also send back.

	~~==How to flash a node in the massive mesh==~~		*[[Solution for Original Tutorial 1]]

	~~'''Create a tar image of the linux file system'''~~		=== Tutorial 1: ===
	~~Change to the root folder of the linux filesystem~~
	~~tar cvf .../hardcore-linux.tar .~~

	~~'''Make an image of~~ the ~~linux file system~~ on the ~~flash card'''~~		Create a "hello world" program which sends the string "Goodbye world" from one host to another host using UDP/IP. You will need to create a sender on one host and a receiver on the other host
	~~dd if=/dev/sdb of=hardcore~~-~~linux.img~~		* [[Solution for tutorial 1 - sender]]
			* [[Solution for tutorial 1 - receiver]]

	~~'''Create a partition on the compact flash card'''~~
	~~cfdisk /dev/sdb~~

	~~'''Make the file system'''~~		=== Tutorial 2: ===
	~~mkfs.ext3 /dev/sdb1~~
	~~tune2fs -c o /dec/sdb1~~

	~~'''Untar file system~~ to ~~flash drive'''~~		Improve on the program in tutorial 1 so that you can send and receive messages. Use an element handler to change the message to be sent.
	~~tar xvf hardcore-linux~~.~~tar -C /media/disk~~

	~~'''Start qemu with info to boot'''~~		=== Tutorial 3: ===
	~~qemu -append root~~=~~/dev/hda1 -kernel/tmp/bzImage /dev/sdb~~

	~~'''Run lilo~~ on ~~flash system once qemu is launched''~~'		Create a new element and packet structure which makes it possible to broadcast a list of beacons that were discovered on one node to all nodes within broadcast range of that node. You only need to send the ssid, channel and rssi for each discovered beacon.
	~~lilo~~
			* Note: You don't need to encapsulate the packet in IP - you can send it using just your packet structure and assume that a click capable node will receive the packet.

	~~'''Now test the flash card'''~~
	~~qemu /dev/sdb~~

	* ~~Current running experiment~~		* In August 2009 we completed a scheduler which is only available on the internal LAN at the moment but will soon be available externally for researchers to schedule time in the lab
	* ~~Timetable of bookings~~		* We have installed a touch screen in the building which will allow you to access information about the mesh lab
