This scripts address several problems with Xlink Kai + Ubuntu.

As we all know Ubuntu comes bundled with the Gnome Network Manager which isn't suited for quick SSID changes...

In fact I don't know of any Network Manager actually being a HELP for Kai... Evil or Very Mad

Here I will list some of the known problems with Ubuntu + Network Managers...

1. Weird disconnect behaviour for Adhoc-Networks...
2. Sucky Refresh Rate - making it impossible to join SSID changing games...
3. No way to copy the changing SSID for your clients...

The following two scripts will do the following for you...

1. Temporarly deactivate the Network Manager.
2. Reconnect your Wired Network via DHCP so you have Internet Access.
3. Switch your WLAN Interface into Adhoc Mode + Channel 1.
4. Auto-Connect to the initial PSP SSID (Lobby).
5. Allow you to easily get connected to other players.

The following scripts need to be executed as root using sudo.

The clientman.sh script is for clients (joiners) while the hostman.sh is for the server (host).

The scripts are similiar in working, but have a few differences.

The hostman.sh changes SSID 100% automatically... and displays the new SSID it joins... this allows the host to easily copy the new SSID (hostkey) and pass it onto others...

The clientman.sh connects to the initial lobby SSID... and keeps asking for hostkeys (ex. PSP_AULES12345_zXaB12h, zXaB12h would be the hostkey...).

Just copy the hostkey into the terminal, press enter and you are done.
The client now joined the right SSID network.

Once you are done playing and want the Network-Manager back, simply terminate the script using Ctrl + C and it will undo all the changes to the interfaces, reactivating the Network-Manager.

Good Luck fellow Kaians, this should make Xlink Kai a lot more attractive for Linux Users because Linux has a way better WLAN Device Compatiblity for Xlink Kai.

The scripts are configured to use eth0 as your wired (internet) and wlan0 as your wlan (kai) interface...

If your devices have different names, you will have to alter the scripts to reflect those differences.

I wont be updating those scripts ever I fear though, cause they work for me and that is all I wanted to achieve with those.

Support is given if someone absolutely cannot handle them. Twisted Evil

hostman.sh -> http://pastebin.com/t7F8NKkR
clientman.sh -> http://pastebin.com/442RCq07

Keep in mind that the hostman.sh script is a one-way-ticket...
Lobby to Ingame Auto-Pickup of SSID works, but not the other way around...

The initial version of it supported it, but I had to limit "both-way-detection" because of the way the CLI WLAN Tools work...

Which means... you have to restart the hostman.sh script for each new "round" you host.

Keep in mind to remove the tick in the "Automatically Connect" Checkbox in the Ubuntu Network Manager for every Infrastructure WLAN Connection.

For some reason the WLAN device can't get switched into Adhoc Mode if you have a "Auto-Connect" Infrastructure Network in your Network-Manager... even though my script deactivates it...

Strange but... oh well, atleast we know we have to deactivate that before starting the script. Twisted Evil
