    Re: How To: Manual Network Configuration without the need for Network Manager

    kevdog, I'm not using the wired interface anymore now that the wireless is working, but that may have been the cause of those errors earlier when I was using it.

    Thanks for all your help, kevdog and drpaul. Now it just remains to be seen if I can connect to other networks, but I'll cross that bridge when I come to it

    OBTW, you could always put the hex key in instead of the password.
    See, it SAYS I'm connected since I tried to connect through System/Admin/Network then unlock it, and click properties on my wireless network, choose WPA (Personal), and enter the password 519. However, as soon as I get out of properties and it refreshes or whatever, and I go back into properties, the password is erased every time and I don't get internet despite what my ifconfig says about my having an IP address.

    Here's the output when I edited the wpa supplicant file with the hex equivalent of 519 (which is %35%31%39, right?)
    Code:

    Re: How To: Manual Network Configuration without the need for Network Manager

    First I'm really confused by what you are doing. If you are trying to use Network Manager, WICD or any other GUI, thats fine, but you can't do a manual connection and use a GUI at the same time. It would work. So I dont quite understand the things you were saying about System/Admin/Network and such.

    Second if you read your output:

    ctrl_iface bind(PF_UNIX) failed: Address already in use
    ctrl_iface exists and seems to be in use - cannot override it
    Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
    Failed to initialize control interface '/var/run/wpa_supplicant'.
    You may have another wpa_supplicant process already running or the file was
    left by an unclean termination of wpa_supplicant in which case you will need
    to manually remove this file before starting wpa_supplicant again.

    You seem to have a process (a GUI perhaps??) already using the /var/run/wpa_supplicant/wlan0 socket. So you must delete this socket (which can be treated like a file) with:
    sudo rm -rf /var/run/wpa_supplicant

    And just for reference (since a lot of people are responding to this thread all of a sudden and its hard for me to keep people straight) if you could post your wpa_supplicant.conf file along with your commands you are typing that would be great for reference.

    Re: How To: Manual Network Configuration without the need for Network Manager

    I am following the steps described in this HOWTO to connect to WPA1 encrypted wifi network. But sometimes I am unable to connect to my wifi network(No working leases in persistent database - sleeping). Am using the following script to connect to wifi network.

    Code:
    cat wifi_scripts/wifi_start.sh
    #!/bin/sh
    sudo ifconfig wlan0 down
    sudo dhclient -r wlan0
    sudo wpa_supplicant -Bw -Dwext -iwlan0 -c/etc/wpa_supplicant.conf 
    sudo ifconfig wlan0 up
    sudo iwconfig wlan0 mode Managed
    sudo dhclient wlan0
    Once in a while ,I am getting the following output while running this script and connection fails ,

    I'm trying to just get wireless internet to work. Be it through the terminal or through a GUI. I was explaining to Paul why my ifconfig was showing an IP address but I still couldn't get any internet. But since GUI has failed me I guess I'm just trying to connect through the terminal.

    I dont know where it starts and stops, because it just keeps going. It never gives me a chance to go on to the next step since it seems to be stuck in some loop.

    Here's my wpa supplicant file:
    Code:
    ap_scan=1
    ctrl_interface=/var/run/wpa_supplicant 
    
    network={
            ssid="girlfess"
            scan_ssid=0
            proto=WPA
            key_mgmt=WPA-PSK
            psk="%35%31%39"
            pairwise=TKIP
            group=TKIP
    }

    Re: How To: Manual Network Configuration without the need for Network Manager

    Try doing the following b/c it looks like things are working

    Instead of this:
    sudo wpa_supplicant -w -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd

    Do this:
    sudo wpa_supplicant -Bw -Dwext -iwlan0 -c/etc/wpa_supplicant.conf

    You will not get any debug parameters with the second command since it will be run in the background (hence the B flag). It looked like your debug output was positive from the previous post, so you might be in luck.

    Thanks a lot for helping me out so much. I'd be completely at a loss without your help.

    OK so this is what happened when I tried to connect via command line:
    Code:

    Sorry, try again.

    I'm excited because this is as far as I've got in my 2 week long quest for wireless! It's like a puzzle that I just have to solve. Unfortunately, I'm not there yet. Do you know what went wrong this time? What's a pid?

    Re: How To: Manual Network Configuration without the need for Network Manager

    OK

    Do the following:

    1. Change the wpa password to only contain letter or numbers -- no funky stuff -- this sometimes is a problem -- make it really simple for right now!

    2. Pop open two command windows

    Window #1:
    sudo ifconfig wlan0 down
    sudo dhclient -r wlan0
    sudo wpa_supplicant -w -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd

    The output in this window will likely not stop

    Stop with Cntl-C when need be but run commands in Window#2 while output is going in Window#1

    Window #2:
    sudo ifconfig wlan0 up
    sudo iwconfig wlan0 mode Managed
    sudo dhclient wlan0

    Can you lastly check dmesg for me. I don't want you to post the entire file. dmesg is a long file. Probably best checked right after boot since its a lot smaller, but it doesnt matter. Scan the output (dmesg | more -- use spacebar to get next page) and look for wlan0 or something about your network card. Make sure you see specifically that wpa is supported by your wireless driver, and there are no errors associated with your card -- read carefully -- they are easy to miss).

    Lastly post
    iwlist scan

    Output for this method was the same as my last post where I added -Bw.Ended in:
    Code:
    No DHCPOFFERS received.
    No working leases in persistent database - sleeping.
