Now you can configure network interfaces by editing /etc/network/interfaces. The IP addresses
for eth0, eth1 and wlan0

are statically assigned by default(see the Listing below).

post-up and post-down directives switch blue LED on and off signaling that wireless interface is
up or down (KS8695 based devices only). The wireless interface wlan0 will be configured with the
wpa_supplicant utility (see Section 4.1).
Setup gateway and DNS server Assuming your router has IP address 192.168.254.1 the OnRISC
will be configured in the following way:
1. change eth0 section of /etc/network/interfaces file
auto eth0
iface eth0 inet static
address 192.168.254.254
netmask 255.255.255.0
gateway 192.168.254.1
2. insert following line to the /etc/resolv.conf
4
nameserver 192.168.254.1
3
to activate wlan0 uncomment the #auto wlan0 line in /etc/networking/interfaces
4
see man resolv.conf for explanations
