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

Use the static method modifiy the file tc/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

#

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
