Gumstix
Hardware
(2)The gumstix motherboard has a 600MHz Marvell XScale processor, 128MB of RAM, and 32MB of flash.
(2)The 80 pin expansion socket is attached to a network interface card for TCP/IP networking.
(3)The 60 pin expansion socket has a breakout-vx card to allow access to the I2C signals, serial ports, and various other GPIO possibilities.
(2)Additionally, 4V power adapters
(10)screw and spacer kits are needed.
(2)TTL to serial adapters
Software
I2C installation
cgi-bin programs
Boa Webserver is the webserver on the Gumstix.
cgicc is the C++ library used for handling web scripts.
Buildroot is the system used to build the root image for the gumstix.

Misc
Setting the date
The busybox date -s accepts a very limited format. Use it from another Linux box as follows:
ssh root@134.50.203.56 "echo date -s `date +%m%d%H%M%Y`"
Setting Static IP adress
In the LDS use the static method modifiy the file etc/network/interfaces so it says
auto eth0
iface eth0 inet static
address 134.50.3.175
netmask 255.255.255.0
network 134.50.254.5
broadcast 134.50.3.255
For JLab Use the static method modifiy the file etc/network/interfaces so it says
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8) # The loopback interface # auto lo iface lo inet loopback # # Wired interfacesq # auto eth0 iface eth0 inet static address 129.57.36.61 #network 129.57.1.0 gateway 129.57.36.1 netmask 255.255.252.0 broadcast 129.57.39.255 # if netduo attached uncomment lines below #auto eth1 #iface eth1 inet dhcp #
In Hall C we had
auto eth0
iface eth0 inet static
address 129.57.168.91
netmask 255.255.252.0
network 129.57.168.0
broadcast 129.57.171.255
Then do commands
ifdown ifup eth0
Must check the if address of a machine which is connected to the same network by ifconfig and route -n
ifconfig interfaces
inet addr >>> address
Bcast >>> broadcast
route -n Genmask >>> netmask Gateway >>> gateway
