simplest firewalling rules

this basically denies all incoming connection that is not initiated by the user and allowing all authorised traffic to flow in.

iptables -A INPUT -m state –state RELATED,ESTABLISHED -j ACCEPT
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -j DROP
iptables -A OUTPUT -j ACCEPT
iptables -A FORWARD -j DROP

to unblock ping request

iptables -A INPUT -p icmp -j ACCEPT

basic wireless connectivity

*reference for NC team*
First find you network device.

#ifconfig

you’ll get a listing of devices and pick your wireless device.
example: eth1, wlan0

then to connect with command line

#iwconfig wlan0 essid “wirelessname” key open [1] 0123456789

to set ip address manually and overide whatever dhcp pushed from the network

#ifconfig wlan0 192.168.0.254
#route add default gw 192.168.0.1
