Installing Cerebro

In a terminal:

su -
yum -y remove cerebro
yum -y install git python-setuptools-devel.noarch
git clone git://dev.laptop.org/projects/cerebro
cd cerebro
./install.sh

Reboot.

init.d script

The current init.d script (/root/cerebro/bin/cerebro.init) fails to stop Cerebro because some of the commands in /etc/rc.d/init.d/functions cannot handle the full string "cerebro -p -i msh0 &". The following is a quick fix for this problem:

diff newinit cerebro/bin/cerebro.init 
31,32c31,32
<         if [ -n "`pidof -x ${prog%%\ *}`" ] ; then
<             killproc ${prog%%\ *}
---
>         if [ -n "`pidfileofproc $prog`" ] ; then
>             killproc $prog

Notes

The Cerebro package in the latest Joyride builds (joyride-2130 or later) is largely equivalent to what you get by manually installing Cerebro from the git repository.

Version of your installed Cerebro package: "yum info cerebro"

Version in git: in your /root/cerebro folder, "git-log"

Assuming these match, the following things (needed for the study but not for Cerebro functionality) are done by /root/cerebro/install.sh but not by the Cerebro package:

• Add ypod's ssh key to your authorized_keys
• Set Cerebro to start at boot
• Add trackclient.py to your rc.local

setup_cerebro.sh in my public is a script based on install.sh (cut out the actions redundant with the package and added the git stuff) that you can use to do this. Note that if you do this, cerebroui will be in your path, whereas install.sh puts it in your home directory.

keeper.py

           self.buddy['ip'] = os.popen('ifconfig eth0|grep "inet addr"|cut -d: -f2|cut -d\  -f1').readline().strip()
