NetStumbler is a program that show the local wifi networks and the channel they use. This is useful if one needs to choose a somewhat free channel for one's wifi connection. But this is in Windows.

What about an Ubuntu alternative?


Update after answer on using Kismet+Kismon: That is not at all like NetStumbler: I have to manually edit a configuration file.

From the links provided I understand that i have to install Kismet, and run sudo lshw -C network to get the needed data that I have to enter into a configuration file that is accessible by sudo gedit /etc/kismet/kismet.conf.

Running sudo lshw -C network, I get:

 *-network

       resources: irq:21 memory:c8400000-c8400fff

So confusing. 9 pages of forum for that? can i get simple instructions?

Also, I worry for something like:

~$ kismet
Launching kismet_server: //usr/bin/kismet_server
Suid priv-dropping disabled.  This may not be secure.
Done

What does this mean, not secure?

Also, here it says: "when quitting kismet, it leaves your wireless card stuck in monitor mode. To revert back to Managed mode (client mode), the commands would be similar to the following:

sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode Managed
sudo ifconfig wlan0 up 

What does this mean? Do I have to run those (in fact not those lines, but other, similar but different info ---) each time (after) I use Kismet?

In the configuration file I have edited only 2 lines:

13 suiduser=cipricus

and

27 source=ipw2200,eth1,intel

But this is what happens:

~$ kismet
Launching kismet_server: //usr/bin/kismet_server
Suid priv-dropping disabled.  This may not be secure.
Done.

And:

~$ kismon
