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.
(2)The 60 pin expansion socket has a breakout-vx card to allow access to the I2C signals, serial ports, and various other GPIO possibilities.
(1)Additionally, 4V power adapters
(3)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
