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

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
#choose only one address line
#gumstick green ethernet cables #1
        address 134.50.3.93
#gumstick blue ethernet cables #2
        address 134.50.3.175
        netmask 255.255.255.0
        network 134.50.3.0
        broadcast 134.50.3.255
        gateway 134.50.3.254

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

It seems to only use the first DNS entry in /etc/resolv.conf For ISU's network,one of the following addresses needs to be the first nameserver line in the file.
