I came across an article on Google a while back and i thought i would share it. Apparently Google is trying to save the planet so they came up with www.blackle.com . You can read about the rest from:

Ubuntu Feisty? Linksys WUSB54GP? WPA ? Can’t get it to work??

Filed under: Technical — george @ 4:17 pm

Hey guys,

I wasted a day of my project time trying to connect an ubuntu feisty box without internet to a wireless network. Since Ubuntu doesn’t include drivers for this network interface and since you won’t find any on the Linksys page as they don’ support linux operating systems you will need to do the following:

Find an empty cd /dvd or usb stick. Find and download the following packages for ubuntu feisty:
ndiswrapper-common
ndiswrapper-utils
Then go to: http://floppyjoes.homeip.net/phpBB2/viewtopic.php?t=21 and download the drivers at the end and add them to the medium you are using. Then take that medium (cd / dvd/ usb stick) to your ubuntu machine. When mounted run the common and utils packages. They end in .deb so ubuntu will pick them up as installation packages. Install the packages and then go to the command line and run : sudo ndiswrapper to see if the command is available. The rest of the instructions can be followed from floppyjoes page above starting from the begining and skipping the part about getting ndiswrapper.

Remember that the default driver does not work the way it should so we need to go through all this process.

Thats all! Let me know if you have any problems with this!

UPDATE:

It appears to be something to be proud of if you  manage to get wifi working on any linux distro :P   Well the above kind of stopped working but i have an update on this issue.  This is what i did:

  • Firstly have a look at http://offog.org/kentservices.html
  • Then also have a look at: http://ubuntuforums.org/showthread.php?p=1455704#post1455704
  • So in other words edit the /etc/network/interfaces file and under your wlan0 interface or whatever it might be add the following
    • wpa-driver wext  #from what i understand this is the generic driver which covers most cards around
    • wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
  • Now go and create a file under /etc/wpa_supplicant/ named wpa_supplicant.conf
    • you can use the touch command to create the file or just go straight with vi or pico/nano and create it
  • Then add the following:
  • # this is the setup for the wireless network @ kent
    network= {
    ssid=”eduroam”
    key_mgmt=WPA-EAP
    eap=PEAP
    identity=”***”
    password=”***” }
  • the restart your network service using: /etc/init.d/networking restart

One thing i did before this was also update the network manager used in Ubuntu 7.04 Feisty from here: http://ubuntuforums.org/showpost.php?p=2663064&postcount=88 .  If you have networking via ethernet and a cable you are in luck.  If not, download all dependancies for the packages and put them somewhere.  WIFI on ubuntu using wpa is NOT easy and am guessing each problem has a unique solution

Ubuntu remote X session fails / error / problem

Filed under: Technical — george @ 10:55 am

If you are running an ubuntu machine/box somewhere and you are using x sessions, or want to use them then you will need to configure your ubuntu installation to do just that. The first step is to go to System > Administration > login window preferences. Then go to Remote and select Style: Same as local. This should allow you to start remote XDMCP sessions. If you are using windows my favorite client comes bundled with the windows x server package called Xming ( look it up on the internet). I do not use the server it self but i use the client that comes with it. If you choose to start Xlaunch, choose 1 window, “Open Session via XDMCP”, click next, enter the IP address of the host to connect to (or choose the Search For Hosts option) and then finish it will let you start a remote X session with that server using the XDMCP protocol. If you come up with a problem similar to the one i had today, i.e. the x server crashing after trying to loggin (which happened after my first restart) , all you see remotely is the background, when trying to log into the machine entering the username and password simply prompts you to enter it again, then the solution i found and worked for me is to restart the Ubuntu machine, log in localy, go back to System > Administration > Log in Window Preferences and under general tick the option that says “Restart the Xserver with each login”. That should fix it!
