o.k. I got WEP up and running, so I now have at least a little bit of protection.

Here again some outputs:

Now we just need to get WPA up and running.

What do we do?

Ken

As the others have mentioned you should be good to go - once you configure your router and get passkey go to system/administration/networking and set up properties. Main thing to watch is key type - plain or hex , just make sure all settings match exactly. You may have to deactivate interface first and reboot but that's about it. Obviously little more work required for wpa but wep is a start.

Edit: Oops too late

o.k. but is there any known tutorial for setting up the wg511 v3 made in china on ubuntu drapper, soI know what to put in the wpa_supplicant.conf and in /etc/network/interface ?

I would hate to put the wrong stuff in there and then have to reinstall again to have a clean system.

Thank`s a lot
Ken

Try this - https://help.ubuntu.com/community/WifiDocs/WPAHowTo although can't vouch for it's effectiveness as haven't tried it myself. As an aside what I do now, after many broken systems, is use a rescue cd with partimage to backup my working distros onto free partition and dvd. Then if things go haywire I just restore the image and I'm left with a working system again.

o.k. we are a bit further yet again.
after running this command
wpa_passphrase ESSID NetworkKey >> /etc/wpa_supplicant.conf
and this command
wpa_supplicant -Dprism54 -iwlan0 -c /etc/wpa_supplicant.conf -dd

I got a connection with wpa.
But as soon as I close the terminal, the connection is terminated.

I just had to change the drinver, since mine is ndiswrapper and the directory the wpa_supplicant.conf is at.
But it worked.

So, what do I do now?

The tutorial you linked, dosn`t really help, since ubuntu drapper ist really mentioned in terms of configuration.

Ken

Have you tried the wpa_supplicant programme yet? (Substitute the prism part for ndiswrapper).

Then run the dhclient wlan0

See what happens...

Richard

Again not having dabbled in it myself can only point to this http://packages.ubuntu.com/dapper/net/wpagui and rely on the blurb "A Qt-based application is available that might make configuration easier" being true!

Excellent, you are almost there then. If you run the same wpa_supplicant command with -B instead of -dd, it will background the process.

You should also look at networkmanager (It is in the repository). This should allow you to attach automatically. I can't remember though in Ubuntu if you have to comment out the interfaces within /etc/network/interfaces in order for network manager to take control from ifup/ifdown.


I hope this helps

Richard

o.k. but could you give me an example, on how to enter it into wich scripts?

what I have tried before, that didn`t work is the following:

I will leave away the parts about ndiswrappeiong and blacklisting, since we know, the card works.

according to this turtorial (it is in german), I modified some scripts as followed:
http://wiki.ubuntuusers.de/WLAN/Konfiguration


/etc/networking/interface

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp

auto eth2
iface eth2 inet dhcp

auto ath0
iface ath0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
post_up wpa_supplicant -Dwext -iwlan0 -c/etc/wpasupplicant/wpa_supplicant.conf -Bw
#post-up sleep 5
post-down killall wpa_supplicant
post-down rm -r /var/run/wpa_supplicant/

and /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

network={
ssid="privatnetz"
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
#psk="xxxxxxxx" (den sag ich nicht)
psk=f2b60a50a6e157a1d09a4d51ff6dbb96089efedd18cc2a870e915068f07c6283
}

At the moment, these files on the newly installed system look as followed:

/etc/networkiing/interface

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto eth2
iface eth2 inet dhcp

auto ath0
iface ath0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
wireless-essid privatnetz
wireless-key B719A7B92CEC5EE66FFAC5669B

auto eth1

and /etc/wpa_supplicant/wpa_supplicant.conf

network={
ssid="privatnetz
psk="xxxxxxx" (my key)
priority=5
}

so, regarding to the commands we entered yesterday night, what would I have to include or change in the two scrips?

What I have just done, but I can first check if it works this evenning, when I get back home, I changed the interface sript from dhcp to static as followed:

auto wlan0
iface wlan0 inet static
adress 192.168.253.102
netmask 255.255.255.0
gateway 192.168.253.1
wpa_supplicant -Dndiswrapper -iwlan0 -c /etc/wpa_supplicnat/wpa_supplicant.conf -B
wireless-essid privatnetz
wireless-key B719A7B92CEC5EE66FFAC5669B

and I added the line: ctrl_interface=/var/run/wpa_supplicant to /etc/wpa_supplicant/wpa_supplicant.conf

Would this be about the right way to do it?


Thanks
Ken

In the wpa_supplicant --help and in the wpa_supplicant man pages, they mention the wpi_cli.
But when I run the command wpa_cli command, I only get told: Could not connect to wpa_supplicant - re-trying

Can it be, that the wpa_supplicant is not running?

I don`t understand that.

Ken

I think you have to have wpa_supplicant running as stated before, and then run wpa_cli -i wlan0

I do know that it doesn't work unless you have specified;

ctrl_interface=/var/run/wpa_supplicant

in your /etc/wpa_supplicant.conf file.

As for your scripts. All I did was to install networkmanager and comment out any reference to a lan connection in /etc/network/interfaces

I'm not sure what the other stuff is. I don't think you need to specify it.

Richard

hi,

I have ctrl_interface=/var/run/wpa_supplicant im m y/etc/network/interfaces , but I still get that message from wpa_cli.

When I ran the command:
wpa_passphrase ESSID NetworkKey >> /etc/wpa_supplicant.conf

the key was, as it seems, entered in the conf file, as you can see in the output.

When I ran this command:
wpa_supplicant -Dprism54 -iwlan0 -c /etc/wpa_supplicant.conf -dd

WPA came up and it worked, but I didn`t any prompt in the terminal window.
First after ctrl+V I got my prompt back, but the network connection was terminated.

What exactly should I do now?

At the moment, my scripts are as followed:

wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

network={
ssid="privatnetz
psk="xxxxxxx" (my key)
priority=5
}

and /etc/network/interfaces

auto wlan0
iface wlan0 inet static
adress 192.168.253.102
netmask 255.255.255.0
gateway 192.168.253.1
wpa_supplicant -Dndiswrapper -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B
wireless-essid privatnetz
wireless-key B719A7B92CEC5EE66FFAC5669B


I`m sorry to ask so much, but I am not really understanding, why all the tutorials wont work.

Ken

No worries,

I'll go through the steps that got mine working.

1) WPA_PASSPHRASE ESSID NetworkKey >> /etc/wpa_supplicant.conf
2) Install networkmanager (There may also be gnome-networkmanager i think)
3) Comment out all entries relating to wlan0 from your /etc/network/interfaces. You have put static entries in. Remove them.
Reboot.

Should be all there is to it.

It`ll be a few hours, uuntill I can do it, since I`m still in the office.

But yesterday, when retried
WPA_PASSPHRASE ESSID NetworkKey >> /etc/wpa_supplicant.conf

I get an access denied

I would like to have it up and running during boot, so I don`t have to enter any commands after starting up the system.

What do you mean with "comment out all entries with wlan0 in interfaces"?

Ken

You are not doing it as root.

Thats the point of network manager.

Try just renaming it to something else for now.
