How to Setting IP address in Backtrack 4

Linux Back Track 4 already released, as a beginner in Back Track i want to set my ip address for ethernet card. In windows operating system we can edit our ip address through GUI (graphical user interface), but in Back Track i can not do that.
After searching back track tutorial for beginner, i found that in back track we can set ip address by using command line in console.

These are my step to set ip address:

1. Click Back Track icon on the left bottom of desktop (or click quick launch konsole)
2. Type "ifconfig eth0 192.168.1.5" and press "enter" (this mean we set ip address 192.168.1.5 for ethernet card)
3. Type "route add default gw 192.168.1.1" and press "enter" (this mean we set default get way 192.168.1.1 for this ethernet, and this is depend on our network)
4. Type "echo nameserver 202.134.0.155 > /etc/resolve.conf" and press enter (this mean we set dns server ip address with: 202.134.0.155, and this is depend on our ISP)
5. If finish we can check our connection by pinging our getway (in this example "ping 192.168.1.1") if this connection OK, we can see "64 bytes from 192.168.1.1: icmp_seq=1 ttl=254 time=0.961 ms" appear in our console. Time in ms depend on our network.

I hope this post can help others.
