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

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
