How to Start Networking in Backtrack

to bring you down and disable the interface type:

#ifdown eth0

hi sleep

Is it still necessary to set static IP in the /etc/network/interfaces file in the method your using?

I having trouble basically trying to get any signals in wicd network manager with my Alfa 036h.
My Alfa 036h uses interfaces wlan0 and mon1, does that mean I need to setup iface in /etc/network/interfaces file for mon1?

Mines currently looks similar to below

Quote:

root@bt:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp

address 192.168.0.7
netmask 255.255.255.0
network 192.168.1.1
broadcast 192.168.0.255
gateway 192.168.0.1

Also, Im not sure the static ip details I've entered are correct. Anyone have any tutorials on this?
Im not sure which details to put here if Im connecting to multiple wep connections for example?I bascially want to be able to go to Wicd, choose the connection and type in the wep key, if possible.
Im using HDD install of bt4 on vmare.

EDIT: found this tutorial- after i run through that it will probably answer my question.

Tnx I solved it. I just had to modify /etc/network/interfaces :)

Getting WLAN to work from command line:

If somenone knows how to connect wlan via dhcp from cli, please let me know how

In my case, the wireless nic is on eth1

ifconfig eth1 down
ifconfig eth1 10.0.0.4
ifconfig eth1 netmask 255.255.255.0
ifconfig default gw 10.0.0.2

change the dns server address in the /etc/resolv.conf if needed

iwconfig eth1 key restricted
iwconfig eth1 key s:[passphrase] (or without the "s:" if inputting HEX key)
iwconfig eth1 mode Managed
iwconfig essid MyNetwork
iwconfig channel 6
ifconfig eth1 up

try to ping the default gateway, then Google and it should work.

For some reason, I cannot get DHCP response with dhclient even from a unprotected hotspot without network-manager or WICD. I'd like to know why

Very nice! It might be more better if you make a distinction between your expainations and the commonds! I am a new BT4 user! And I would like to study this thread carefully!Thanks a lot!

Solution for me in BackTrack 4:
root@bt:~# dhclient eth0

Regards

First of all sorry for my poor English.
I have a problem while connecting to the nework. I read this thread and tried to start the network by editing file "interfaces" and by another method - wicd manager. Nothing works! While trying ping my gateway (or any other PC at my network) I got the answer "Destination Host Unreachable". I have any DHCP servers at my network. ifconfig shows my eth0 interface (it is on realtek chipset). It is up and maybe works.
Such problem is with Wi-FI card (I tried to use Intel Pro wireless card and card on Atheros chipsets).
Please help me by advice. What I'm doing wrong?

Hi !

I have the same problem with WiFi.

Wireless PCI Card CNP-WF511 (chip: RTL8185L)

I read all thread's but have not found an answer, how to configure Wireless.

I can only connect to internet with eth0.

When i type :
iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

Clicking the Networking Icon in the System Tray, i see only:
Wired network - with mystical IP adress.
No wireless networks found

Someone can help me, please ?

Hello guys,

What is the difference between /etc/init.d/networking start and /etc/init.d/NetworkManager start.

Could you can explain the difference, and functions in that?

Wasn't network manager used in the older versions? I was under the impression that wicd replaced the network manager?

The information worked well. Thanks
