TS-4900 Network configuration example

Most commonly networks will offer DHCP which can be set up with one command:

# To setup the network for this boot:
udhcpc -i eth0
# Or if you're on a baseboard with a second ethernet port, you can use that as:
udhcpc -i eth1

# To instead manually configure the interface for this boot:
killall udhcpc
# Set IP + subnet mask
ifconfig eth0 192.168.0.50 netmask 255.255.255.0
# Set default gateway, usually your router
route add default gw 192.168.0.1
# Set your DNS server
echo "nameserver 8.8.8.8" > /etc/resolv.conf

To make your network settings take effect on startup in Yocto, edit /etc/network/interfaces:

 # We always want the loopback interface.                          
 #                                                                 
 auto lo                                                           
 iface lo inet loopback                                            
                                                                   
 auto eth0                                                         
 iface eth0 inet static                                            
   address 192.168.0.50                                            
   netmask 255.255.255.0                                           
   gateway 192.168.0.1                                             
 auto eth1
