Creating Wireless Ad-Hoc Networks on Linux Boxes

Hi,

I have two Linux Boxes, one with Slackware 12 and other with Ubuntu 7.10. The Ubuntu machine has an USB wifi stick, model DWL-G132, working nice with ndiswrapper. The Slackware 12 machine is a notebook with Intel 2200BG wireless. They both work with access points without bugs.

I want to create a Ad-Hoc network using these two machines. On the Slackware machine, i'm performing the following commands:

Code:

# iwconfig eth1 mode Ad-Hoc

# iwconfig eth1 essid pulse

# iwconfig eth1 channel 8 

# ifconfig eth1 10.0.0.1 up

On the Ubuntu box, i'm using these commands:

Code:

sudo /etc/dbus-1/event.d/25NetworkManager stop

sudo iwconfig wlan0 mode Ad-Hoc

sudo iwconfig wlan0 essid pulse

sudo iwconfig wlan0 channel 8

sudo iwconfig wlan0 10.0.0.2 up

I can't ping 10.0.0.2 from 10.0.0.1 and the other way around neither. There are no other interfaces or networks set on the machines. The other services aren't available either. Am I missing any step?

Yeah that "should" work, sadly ad-hoc mode has become the neglected step-child of the 802.11 service modes. Can you post back the output from "iwconfig" and "ifconfig", most important being the cell ID from iwconfig. Its formated like a mac address, and if the network were properly established on the 802.11 layer 2, they would match between the two interfaces.

Cheers,

Ok, I'll check that ID. But the steps i'm taking are ok? Any command missing?

Yeah, I mean, I was doing sort of the same thing a week ago, nat'ing from an ad-hoc network to my evdo card, and those were the commands I used. Some drivers support ad-hoc better than others. I'm almost certain your ipw2200 card will do ad-hoc just fine, its the ndiswrapper'd one I would think may be sketchy.

If the Cell ID's don't match, that's certainly the problem though.

Cheers,
