Nickbenj: /* Setting Static IP adress */

===Hardware===
(2)The gumstix [http://www.gumstix.com/store/catalog/product_info.php?products_id=210 motherboard] has a 600MHz Marvell XScale processor, 128MB of RAM, and 32MB of flash.
 
(2)The 80 pin expansion socket is attached to a [http://www.gumstix.com/store/catalog/product_info.php?products_id=207 network interface card] for TCP/IP networking.
 
(2)The 60 pin expansion socket has a [http://www.gumstix.com/store/catalog/product_info.php?products_id=184 breakout-vx] card to allow access to the I2C signals, serial ports, and various other GPIO possibilities.
 
(1)Additionally, [http://www.gumstix.com/store/catalog/product_info.php?products_id=148 4V power adapters]

==Misc==
===Setting the date===
The busybox '''date -s''' accepts a very limited format. Use it from another Linux box as follows:
<pre>
ssh root@134.50.203.56 "echo date -s `date +%m%d%H%M%Y`"
</pre>

===Setting Static IP adress===

In the LDS use the static method modifiy the file etc/network/interfaces so it says

<pre>
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
</pre>

For JLab Use the static method modifiy the file etc/network/interfaces so it says

<pre>

# /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

#

</pre>

In Hall C we had

<pre>
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
</pre>

Then do commands

<pre>
ifdown
ifup eth0
</pre>

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.
<pre>
search isu.edu
nameserver 134.50.57.57
nameserver 134.50.254.5
</pre>
