I start to learn wpa_supplicant recently,and I got the code already,but the code is complicated,and I don't know how to start learning,and Is there any book to discuss the architecture about wpa_supplicant?
View 4 RepliesI am trying to get a wlan connection using my new Wlan-Stick. It has a Atheros ar9271 chipset.
Code:
Bus 001 Device 002: ID 0cf3:1006 Atheros Communications, Inc. TP-Link TL-WN422G v2 802.11g [Atheros AR9271]
Modules ath9k_htc and ath9k_htc_common are loaded. I can scan for network using iwlist or airodump and get the whole lists of networks. I've copied the config file I use with wpa_supplicant from a working system:
Code:
network={
ssid="Pasta"
scan_ssid=1
key_mgmt=WPA-PSK
[code]....
But I am not able to successfully connect:
Code:
[vortexbox.localdomain ~]# wpa_supplicant -i wlan0 -c wpa.test.conf -Dwext
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable
ioctl[SIOCSIWSCAN]: Device or resource busy
[code]....
the "pre-shared key may be incorrect" I have rechecked the key twice and it is correct (actually it cannot be wrong because they file was copied from a working system). I have also tried to connect to a WEP encrypted network using iwconfig without success. I get no error when connecting but iwconfig tells me "Access Point: Not-Associated".Because of the "Device or resource busy" I tried a "lsof | grep -i wlan" but there are no results.
if the NetworkManager uses wpa_supplicant? I normally dont use NetworkManager and decided to try it. I started it and tried it out and it works with WEP and WPA! I cant figure out why using the iwconfig command is not working by itself for WEP. WPA working with NetworkManager is just a bonus though.
View 4 Replies View RelatedWhen I run wpa_gui I get a "Failed to open control connection to wpa_supplicant." message and an endless stream of "PING failed - trying to reconnect". I'm sure wpa_supplicant service is running, it also seems to be working correctly (program logs show activity when I connect to a wpa secured network via gnome network manager).
The location that ctrl_interface (in /etc/wpa_supplicant/wpa_supplicant.conf) points to (/var/run/wpa_supplicant) is an empty folder. I'm able to connect to a simple WPA network at home, but the one at my university needs special configuration and I couldn't get it to work by editing the .conf file. That's why I need the gui. My network card is Atheros Communications Inc. AR928X Wireless Network Adapter, the driver is ath9k.
right now im using the nm-applet but i dont like it. it produces lags. i think the periodical ssid/broadcast check might be the cause :/it lags every minute or so...in games and skype it is very annoying! if there is a possibily to disable these scans in nm-applet it would be fine too.for the moment im "using" this wpa_supplicant config:
Code:
ctrl_interface=/var/run/wpa_supplicant

I've got my laptop working with my UNI's rather complex wifi setup.
I need to get access to my wpa_supplicant file so i can use it with my nook and a few other devices that i need to get wifi access.
Network manager, i know, does all the wpa stuff dynamically and through scripts, so is there any way that i can get network manager to generate my wpa_supplicant config?

First- clean installation of Ubuntu 10.04, with default network manager installed, I had a taskbar icon, and it could see the available wireless networks, could not connect to them, even the ones with no security. Purged all network manager files suggested in various threads here, Installed wicd- it could see all available networks, could connect to unsecured networks, but not to my own secured network. Password was correct in the wicd/configurations file. Removed wicd, and reinstalled network manager from synaptic. I have to network manager applet. When I try to add it to the notification area with alt-f2, applet-nm, I get a brief flash of something in the notification area, but no applet.
System=>Preferences=>network connections shows no wireless connections, but I'm obviously connected to something (probably my neighbors unsecured network) since I"m reaching this webpage. I tried to run sudo wpa_cli from the terminal to see what network the computer is connected to, and it gives me this error:

EDIT 6 Dec: More detailed log from wpa_supplicant I'm using Ubuntu Studio 10.10 x64. I want to get wireless networking going manually. My wireless networking works successfully in Windows 7 x64. I can get it working successfully without encryption but when I try and use WPA-PSK, wpa_supplicant gets stuck in a loop between GROUP_HANDSHAKE and COMPLETED, as shown in the log below.
I've been working mostly off the instructions in this post: [URL]... My laptop is a Dell Studio 1537. It has an Intel Wifi 5100.

I'm wanting to set up a network that has a simple screened subnet architecture. The boarder router will have a switch plugged into it. My servers will be plugged into this switch. Also plugged into this switch will be a dedicated firewall. This firewall will protect the internal network. The boarder router is not very flexible. You can have hosts that use dhcp but that get the same internal I.P address each time their interface is configured.Or you can configure static I.Ps on hosts that are outside the dhcp range of the router, but that have the same subnet address.
The most simple way to set up such a network would be for every interface to have a static internal address that is obtained via dhcp from the boarder router. Like i said the boarder router is doesn't give you much freedom. Meaning that it lets you have a static internal address but not a different network address for different interfaces. That is where the confusion is, for me. If all the interfaces that get theirI.P addresses from the boarder router are on the same network, then what about the systems on the internal network. They might as well get their I.Ps from the boarder router as well, to avoid NAT being done twice before their packets get sent out to the Internet?.I wanted a three interface firewall to separate the DMZ from the internal network, instead of using a screened subnet architecture, but the boarder router only allowed one interface to be in the DMZ, i think and it didn't seem to have a well designed way of controlling the DMZ ie setting a new default gateway etc.
Should i let NAT be done twice for packets from the internal network i.e have the dedicated firewall do dhcp and NAT for the internal network, but this firewall's external interface have a static internal I.P from the boarder router, and the internal I.P of the dedicated firewall have a static internal I.P from the router as well?. It looks like all the interfaces have to have the same network and subnet address, except the machines on the internal network(which can get their I.P from the dedicated firewall)
I have a "bad password" reply using wicd 1.7.0 with WPA and a preshared key within Ubuntu 10.10, i.e., I am unable to make automatic/repeatable wireless connections using wicd without a workaround.
I believe this may be a problem interaction between wicd and the way wpa_supllicant is passing the (preshared) key to the network authority (the router). In my case, I use a Linksys WRT54GL running DD-WRT v24-sp2 (10/10/09) std - build 13064 OpenSource firmware, configured as an Access Point in Mixed mode (b/g).
I have no problem authenticating WPA Personal TKIP or AES from Windows or Mac OS X clients with a variety of wireless adapters (Linksys, D-Link, Lucent, Airport (Mac)) (No intervention is required to produce the secure connections).
With wicd 1.7.0 and wpasupplicant 0.6.10-2 (wext as wpa_supplicant driver selected in wicd by default) on Linux 2.6.35.-24-generic (Ubuntu "Maverick Meerkat") and a Lucent Orinoco Gold 802.11b wireless adapter I am able to connect to the network initialy (one time) without the "bad password" error.
After the initial successful connection, reconnection is not possible (the "bad password" error) ***unless the wireless security settings on the router are re-applied. Once reapplied/resaved, a subsequent attempt to create a wireless connection from the Linux client will succeed without any changes having been made on the client side.
The psk data being sent to the router (with respect to the Wireless security settings) is being cached in such a way the connection is initially possible but defeats subsequent attempts at connection. Perhaps the passkey is cached/stored on the client side (after it is used to make the first connection) in such a way that it will be sent incorrectly upon subequent attempts at connection? Of course, I'm simply guessing, here ... it is by luck that I found the workaround to establish this wireless connection.
**********
BTW, FYI, I was unable to use the Gnome Network-Manager to establish any wireless connections at all. Thus, Network-Manager was uninstalled (sudo apt-get purge network-manager) during the installation of wicd (Ubuntu Software centre). wpa_supplicant was re-installed (Synaptic) after wicd was installed.
Debian doesn't seem to handle the association between wpa_supplicant.conf records, and /etc/network/interfaces. This is in wpa_supplicant.conf:
Code:
network={
ssid="MYSSID"
key_mgmt=WPA-PSK
psk="stuff"
[code]....
What's happening is there are two gray circles as the wifi attempts to connect. The first one turns green, but it never completes the next step. The syslog shows that it's waiting for the (nonexistent) DHCP server to respond. If I turn on DHCP, the connection completes, but the routing is messed up (because at that point it actually tries to use the static IP from /etc/network/interfaces). So it seems to associate eventually, but it's way too late. I need it to associate soon enough to know not to attempt DHCPDISCOVER.

I'm working on a RHEL 6 base image for virtualization and I'm trying to pare down the things that we don't need. Considering none of the virtual servers will have wireless networking, I figured it'd be good to kill that wpa_supplicant process. even with the wpa_supplicant service off, NetworkManager seems to start it right back up. There isn't any wireless devices configured, so I don't know why it does this. I can't even kill the process, it starts back up immediately. Is there something in either the Network Manager or wpa_supplicant config files that would disable it permanently?

View 5 Replies View RelatedI apologize if there's a solution to this somewhere on the forum, but I searched around on google for several hours before posting this, so I assure you, I'm not trying to waste your time.Here's the deal. I have a file/print server running wpa_supplicant on interface wlan0 via ndiswrapper. Its wireless because the location I need the printer in is really inconvenient to have to run wires to, or I wouldn't have this problem.The box is running ubuntu server 10.10, with only ndiswrapper and the associated utils and wpa_supplicant installed in addition to the default packages required for file/print/web serving. (there may be a few trivial packages like Vim that should have no effect whatsoever.)Basically, wpa_supplicant associates fine with the AP, but I can't get any elegant way of getting a IP address with it, DHCP or static makes no difference. My current fix is my rc.local file has:
Code:
sleep 60
dhclient wlan0

i believe it is a wpa_supplicant problem. running ubuntu 10.04 on a toshiba netbook. i have my account which cannot connect to internet, wicd returns an error that it cannot obtain ip address. cannot even connect to a unesecure network for that matter. if i switch users to another user and do the quick switch users i can get internet then i switched back to my main account and here i am postings. how do i begin to hunt down the problem logs, settings how do some of you begin to hunt down the cause of this and where it would be located.

He is using an Intel wireless card, but I am unsure of the exact model. Another question is would Wicd do this automatically or do you still have to use either iwconfig or wpa_supplicant and edit the corresponding config files?

I am running -current on an ASUS eeePC 1000HE. Wireless was working fine up until the time I applied the latest changes from the Slack -current tree, which upgraded wpa_supplicant. Now, no networks are detected.
I looked at some related threads here and did some basic checking: neither the eth1 nor wlan0 interfaces show up in iwconfig or ifconfig output. Am afraid I am still a wireless dunderhead and don't know where to start troubleshooting this issue.
I have heard the wpa_supplicant in roaming mode, although absent from the various Debian (and Debian-related) forums and wikis, can handle automatic connections to a variety of encrypted and open networks as well as network-manager does... and better when using the MadWifi drivers!
