Ubuntu Networking :: WEP Wireless Authentication Rejected (Though Key Is Correct)?

Feb 18, 2011

I have 2 laptops running Ubuntu 10.04. One connects to my Linksys wireless modem fine while the other does not. The one that does not connect, will connect fine within the instances of Windows XP SP3 and Puppy Linux 5.1 that run on the same laptop. Ubuntu wireless worked fine with version 8.04 on this laptop before upgrading to 10.04.

When trying to connect within 10.04, Ubuntu pops up the dialog box to enter the authentication key. It rejects the correct key, and after a moment, pops up the same dialog box asking for the key again. I'm using WEP 40/128-bit encryption and the key I enter in the dialog box is the correct 26-character key.

The laptop is a Toshiba Satellite Pro 6000 (1g ram/40g disk). Here are some vital outputs root@user-laptop:/home/bsmis# iwconfig

lo no wireless extensions.
eth0 no wireless extensions.
irda0 no wireless extensions.
eth1 IEEE 802.11b ESSID:"kr_wireless"

Ubuntu Networking :: Correct Key Rejected - Wireless Net Disappears

Mar 3, 2010

Out of the blue a dialog popped up requesting that I enter the key for my home wireless network. This is of course unexpected since the correct key is defined for that network in my network config. I entered the correct key but it was rejected. I then clicked on the network manager icon in the task bar. Contrary to normal behavior this did not show either my home network or any of the other wireless networks from my neighbors. The only resolution I could find to restore the wireless network was restarting my system. This seems excessive.

Ubuntu :: Authentication Password Rejected On VNC'd Desktop / What To Do?

Feb 8, 2011

I've been using the Ubuntu desktop for a couple of years now, but I don't have much experience using the terminal.

I've just set up a home server using Ubuntu-server 64bit which will be headless and its main function will be a Mythtv backend.

I've worked out how to use VNC to send a desktop from the server to my laptop, but when I try to use any programs which require root privileges such as synaptic or the user/groups manager, the pop-up asking for authentication refuses to accept my password.

Is there a setting I need to change on the server which prevents remote users from getting root privileges on the desktop?

Debian Multimedia :: Authentication - Root PW Rejected / User PW Accepted

Jun 21, 2015

I installed Jessie with Cinnamon alongside Win 7 - all went quite well though I did have to do a bit of guessing along the way.

Following online tutorials etc, I tried to install sudo from the terminal. It did not go well - some stuff appeared that was not shown in the instructions from many sites. So I abandoned it, or so I thought.

Then I discovered that my root password was no longer recognised. So I reset it, following online instructions.

This was successful apparently, as I can log in as root and see this in the terminal.

But on trying to start Synaptic ( and later others), I found that the new root password would is not authenticated, but my user password does authenticate successfully. This seems to be the wrong way round!

X11 connection rejected because of wrong authentication.

The application 'mysql-query-browser-bin' lost its connection to the display localhost:10.0; most likely the X server was shut down or you killed/destroyed the application.

In ssh_config, I do have ForwardX11 set to yes.

Ubuntu Networking :: Correct Drivers For The Wireless Card?

Apr 19, 2010

i have installed ndiswrapper, and the correct drivers for the wireless card.

ndiswrapper -l:
bcmwl5a : driver installed

I seemed to be having a conflict with the generic drivers which loaded for my wifi device 'b43-pci-bridge' and the ndiswrapper drivers i installed.

So i ran the command 'rmmod ssb' and now my broadcomm wireless device is "unclaimed"

lshw -C Network:

Ubuntu :: Keeps Refreshing The Screen Even If Authentication Is Correct

Apr 17, 2010

I was trying to get my brand new xubuntu install on a Dell Latitutude get going with a kvm switch. I shut down the machine -> connected the kvm cable -> powered it back on and the keyboard/mouse work fine in the login screen, HOWEVER, I just can't get past the login screen, it keeps refreshing the screen even if my authentication is correct.

I unplugged the usb kvm cable, restarted but the problem does not go away.

I can't login to recovery mode (press esc during GRUB load), it doesn't offer any recovery options, goes straight to the login screen.

Ubuntu Networking :: 9.10 - Installing Correct Drivers To Get Wireless Running

Feb 13, 2010

I have just installed Ubuntu 9.10 netbook remix for my new laptop. I've tried at great length to install the correct drivers to get my wireless up and running. I'm currently trying to install the Broadcom driver for my 802.11g wireless card. I have downloaded the headers and tools for ubuntu and am proceeding with the instructions given on [URL].

But when I get to these steps I come unstuck
# mkdir hybrid_wl
# cd hybrid_wl
# tar xzf <path>/hybrid-portsrc.tar

I can make the directory and open it but when it comes to the third step I get a message saying that there is no such file or directory.

Debian :: Authentication Failure With Correct Password?

Aug 8, 2011

I was hoping that someone could point me in the right direction. I just did an install and the os is up and running. During install, I set a root password and also set up a regular user account. The only option at login is the regular user acct. Needless to say, the os asks me to provide the root pw for just about everything I need to do.get an authentication failure. (I assume that this is the same as permission). I can find plenty of info on how to restrict access but nothing relevant to my problem. Just to rule out an install problem, I installed the os a 2nd time. I am very sure I have my passwords correct. One other thing to note is that on the 1st install, I used a different pw for root and regular user. On the 2nd, just to keep is as simple as possibl I used the same pw for root and reg user account. I am new to debian, but the distro that I have been using (slackware)

Ubuntu Installation :: Upgrade To 10.04 Leads To Loss Of Correct Screen Resolution / Wireless Networking / Sound

May 4, 2010

Excited at seeing the new features in 10.04, I clicked the Upgrade button tonight. I am now really regretting it! Problems:

1. My screen resolution should be 1280x1024 but the System>Preferences>Monitors control panel only shows 1024x768.

I think I have onboard Realtek graphics. Do I need to install proprietary drivers? Everything worked fine out of the box with 9.10!

2. The sound isn't working. Again I think I have onboard Realtek sound, and again it used to work fine without any intervention from me...

3. Although on first startup wireless networking was working fine, I restarted to see if that would solve the display issue, and wireless networking stopped working too!

I have an RaLink wireless card.

When I used Grub to choose, I got some error messages at startup (e.g. mount couldn't mount /dev), but then it did eventually start up and the sound and wireless networking are working again. But the resolution is still not fixed. It is now offering 1152x864, which it didn't previously, but no 1280x1024 (my screen's native resolution).

Networking :: Capture A Dropped Or Rejected Firewall Packet?

Jul 3, 2011

I'm running ubuntu 11.04, and using firestarter for my firewall. Logging events, all good, but I'd like to be able to (tcp)dump the packets being dropped/rejected. Wireshark is great after the event, but can I hook iptables and tcpdump together somehow so the system logs the entire packet rather than the summary when it says "no"? I've had a quick look/google, but can't find anything. I'm sure somebody must have wanted to do this before - any pointers people?

PS - will keep looking and post the answer if I find one....

Ubuntu :: Active Directory And Wireless - Getting Authentication Error

Jul 27, 2010

Has anyone had success in getting likewise open or another tool to allow domain users to log in with wireless networking? I have an issue where GDM comes up, users attempts to log in and gets authentication error. After a few minutes it works. Centrify has the same issue.

I've tried removing network-manager and using /etc/network/interfaces to set up networking, which helps, but there's a 1-3 minute delay before a user may log in for the first time after a reboot. My theory is gdm gets loaded before networking is up. There's got to be a work around for this. Even having gdm just hanging for a minute while it waits for networking would be acceptable.

OpenSUSE Wireless :: GTC For PEAP Authentication In WPA2?

Sep 20, 2010

So my university has two wireless servers that students can log into: VCU and VCU SafeNet. The regular VCU server works fine in most areas on campus but the library which I imagine I would be spending most of my time in between classes to do work and such. The connection quality for the unsecured server sucks ass there, and I do not use that term lightly. Other students have found success connecting in the library through the SafeNet server and the tech support man in the library was very nice in helping me setting up the security rules to connect to SafeNet in openSUSE.

However, I lack one little thing that would get me internet connection on crack at the library: GTC authentication for PEAP in WPA2. I did some research and found that GTC has not been implemented in the GUI of KNetworkManager even though it was implemented in NetworkManager. The guide that the tech support man printed out for me was for some earlier version of Ubuntu, so I know NetworkManager has had GTC support for a while now and KNetworkManager is still lacking this. I also found a patch for KNetworkManager, but have had no luck implementing it.

General :: Authentication Required By Wireless Network

Mar 9, 2010

I would like to use a wireless network from Ubuntu. In the network drop-down menu I select a network (this is a University network I have an account there). Then I get a windows with the following fields:

Wireless Security: [WPA&WPA2
Enterprise] Authentication:
[Tunneled TLS] Anonymous Identity:
[] CA Certificate: [(None)]
Inner Authentication: [some
letters] User Name: []
Password: []

I put there my user name and password and do not change default value and leave "Anonymous Identity"blank.

As a result of that I get "Authentication required by wireless network". How can I solve this problem?

I think it is important to notice that our system administrator tried to find some files (which are probably needed to be used as "CA Certificate"). He said that he does not know where this file is located on Ubuntu (he support only Windows). So, probably this is direction I need to go. I need to find this file. But may be I am wrong. May be something else needs to be done.

Fedora :: Wireless Connection Hangs On Waiting For Authentication

Mar 20, 2011

Has anyone else been having problems with their wireless network connections since the network manager updates? I have two different networks that I connect to and have in the past had no problems since figuring out what files were missing and had to be either created or corrected and copied into the correct locations. I have tried everything I know to get my secondary wireless connection working to no avail(currently connected through my neighbors unprotected network), from deleting the connection, rebooting and recreating it, editing the files and copying them back into the correct locations and nothing works.

I have even had many crashes while using network manager. Using system-network-config eliminated the crashes but still does not allow the connection to connect. It attempts to connect and just hangs on waiting for authentication after prompting for the WEP key and clicking OK. What in the heck is going on since the devs created all these updates and have once again broken the most important aspect of any usable system, the network? I'm running F14 and KDE 4.6.1.

OpenSUSE Wireless :: Wifi - Ceased To Work - Until WPA Authentication ?

Apr 6, 2011

After instalation of Suse 11.4, wifi worked totally correctly, until the first restart. Then it ceased to work. It looks like everything is working correctly until WPA authentication.

My wifi device


So until now it looks for me that everything works correctly, but after trying to connect the problems begin.

dmesg output:


So the wlan interface authenticates, and then disauthenticates by local choice? a bit about the reason points to wpa_supplicant. Many peoples report that they have multiple copies running, and killing them solves a problem. Sadly I've only one copy, and after being killed it restarts.

Here is wpa_supplicant.log on the first run after install(when it worked)


And here is log of what happens after restart:


I've no way to change from WPA authorization.

Ubuntu :: Disconnection And Connects To Unavailable Wifi - Authentication Required By Wireless Network

Jun 8, 2010

When my router switches off... the wifi signals go off... then why the hell ubuntu keeps on connecting to that very wifi like hell and when doesnt connect shows the prompt to manually connect... with the wifi key already filled in... whats the use of saving the key when it has to ask the question from me either to connect or not?? and if its isnt available... just wait when its available.. and for the prompt,i have only option to cancel(because wifi isnt available at that moment if i select connect it again tries to connect like hell..which it cant) and if i cancel it wont auto-connect when wifi does get available! what the heck?

Windows has this done the right way... when the wifi isnt available.. it dissconnects silently.. and when it becomes available connects silently.. why isnt this been done this way in ubuntu??

Ive attached an image..one can see in the image that it says "authentication required by wireless network" when there isnt any.. as router has gone down!

And the second thing i want to report is that there is no way to report this bug from ubuntu... the launchpad.net talks of going through bug reporting process which is done against a definite package... now how does a user know which package would be causing this error?? there should be a more clear process of reporting such bugs to ubuntu team... which a common man using ubuntu( ubuntu says its most user friendly of all distros right?) can report..
