Toolchain
- Siehe BRN::Development::Toolchain (Mathias' Method)
Kernel
- Siehe BRN::Development::Kernel
- ab dem zweiten Mal: schneller compilieren
build.sh editieren
wichtig ist das "ccache\ "
#! /bin/sh make CROSS_COMPILE=mipsel-linux- CC=ccache\ mipsel-linux-gcc
madwifi.stripped
- build.sh
#!/bin/sh make TARGET=mips-le-elf KERNELPATH=$HOME/projects/brn/madmax/mips/kernel CC=ccache\ mipsel-linux-gcc
Click Kernelmodul bauen
- Kernel kompilieren (build.sh)
- Click kompilieren (erst conf_mips.sh, Warning ignorieren, cd linuxmodule/, make)
- im Verzeichnis linuxmodule: build.sh editieren
#! /bin/sh make TARGET=mips-le-elf CROSS_COMPILE=mipsel-linux- CC=ccache\ mipsel-linux-gcc
Click Modular Router
- Click Modular Router Homepage
- Click Modular Router, Eddie Kohler. Ph.D. thesis
- Dokumente zu Click von der PATS Research Group
Wer macht ähnliches?

How to (temporarily) set up a SDP independent from the running one
- First build everything for the new SDP. To do so, follow Bernhard's description, BUT there are two important differences:
- Change BRN_NEIGHBOR_BEACON_MAGIC in <YOUR_BUILD_DIR>/click/include/clicknet/brn.h to a unique value. (Otherwise there will be problems with an existing SDP!)
- Don't deploy your new package in the last step
- Then the following has to be done for every node that is part of the new SDP infrastructure
Put the new software onto the WGT
scp -r <YOUR_BUILD_DIR>/sdp/package/library/0 root@<wgt_to_be_changed>:/tmp/sdp/library/
Then telnet to the WGT and execute the following commands
cd /tmp/sdp killall S90sdp /usr/sbin/rcclick stop killall click echo 0 > /tmp/sdp/current_id rm /tmp/sdp/current ln -s /tmp/sdp/library/0 /tmp/sdp/current /usr/sbin/rcclick start /tmp/sdp
For convenience we took all these steps using a (strange) script
ssh -XT localhost "/bin/bash -c 'SSH_ASKPASS=/home/brn/brn/unserpassword.sh \ scp -r ~/brn/sdp/openwrt/sdp/package/library/0 root@wgt24:/tmp/sdp/library/'" ssh -XT localhost "/bin/bash -c \"SSH_ASKPASS=/home/brn/brn/unserpassword.sh ssh -n root@wgt24 '\ killall S90sdp ;\ /usr/sbin/rcclick stop ;\ killall click; \ echo 0 > /tmp/sdp/current_id ;\ rm /tmp/sdp/current ;\ ln -s /tmp/sdp/library/0 /tmp/sdp/current; \ /usr/sbin/rcclick start /tmp/sdp '\""
where unserpassword.sh is another script, that outputs the password for the WGT (for obvious reasons not recommended if anyone else has access to the script!) and returns 0.
Now the new SDP should be running and you should be able to deploy software on "your" nodes without affecting the other ones. To get rid of it and restore the original SDP (the SDP the rest of the testbed is running) just reboot the WGT.
IP auf WGT setzen
Mit diesem Skript erzeugt man aus dem Edit-Abschnitt im Wiki eine IP-Liste, die auf die Knoten verteilt wird.
#!/bin/sh
# https://sarwiki.informatik.hu-berlin.de/wiki/index.php?title=BerlinRoofNet&action=edit§ion=2
sed 's/\s//g' | sed -n '/^|wgt/p' | awk -F'|' '{print $22, $10}' > ipmac.txt
Dieses Skript bestimmt die wlan-mac eines bestimmten Knotens und setzt eine IP auf dem wlan-interface (die zu setzende IP wird aus der IP-List geholt, die von obigem Skript erzeugt wurde).
#!/bin/sh
# Verzeichnis bestimmen, in dem Skript liegt (klappt nicht, wenn Aufruf ueber PATH-Variable
DIR=`dirname $0`
# Wlan-MAC bestimmen
WLANMAC=`ifconfig -a | grep wlan0 | awk '{print $5}'`
# IP fuer die MAC aus Datei bestimmen
MYIP=`cat $DIR/ipmac.txt | grep $WLANMAC | awk '{print $1}'`
# IP setzen
ifconfig wlan0 add $MYIP netmask 255.255.255.0
Alles Click beenden
#!/bin/sh killall S90sdp killall click umount /tmp/click rmmod click rmmod proclikefs echo done
Kernelclick mit brn_kernel_gateway.click starten
#!/bin/sh cd /tmp rm -rf /tmp/expl mkdir expl cd expl wget http://merkur/svn/brn/platform/wgt634u/brn/startup/iptables.sh #cp /mnt/efuhrman/knoten/brn_kernel_gateway.click . wget http://merkur/svn/brn/platform/wgt634u/brn/startup/brn_kernel_gateway.click wget http://merkur/svn/brn/platform/wgt634u/brn/startup/startup.sh #cp /tmp/sdp/current/click.ko.gz /tmp/expl # fuer version 22 cp /mnt/efuhrman/knoten/click.ko.gz /tmp/expl cp /mnt/efuhrman/knoten/proclikefs.ko /tmp/expl echo Copy beendet gunzip click.ko.gz insmod proclikefs.ko echo proclikefs geladen insmod click.ko echo click geladen mkdir /tmp/click mount -t click none /tmp/click echo /tmp/click gemountet click-align brn_kernel_gateway.click > aligned.click cat aligned.click > /tmp/click/config echo fertig
