Ubuntu Networking :: 10.04 Will Not Authenticate Secure Wireless?

Jun 6, 2010

however, until this morning I had only been using my wired connection with no problems but when I tried to connect to my home's WPA secured wireless network, it just would not connect. The network manager sees the network and when I click on it, a window pops up asking for authentication. I enter the passphrase, but still it will not connect. I'm using a Lenovo X61 LAPTOP (not tablet).

Networking :: Cannot Seem To Authenticate A Wireless Laptop

Dec 6, 2010

We've got a Debian Lenny + FreeRadius and cannot seem to authenticate a wireless laptop.At this point, all I want is the users file entries to work, with ClearText passwords. Eventually we'll use LDAP but we want this up first with ClearText passwords and MD5.

1. FreeRadius installed, 2.1.10+dfsg-2~bpo50+1 from Debian Backports
2. AirPort v7.5.1, set up for WPA2 Enterprise, ip 10.10.10.75
3. Apple OSX laptop, 10.5.8

When running 'freeradius -Xxx' from the Debian cli I can see the authentication fail as though the OSX machine (or the AirPort router?) isn't passing along the password (from the FreeRadius cli run).Additionally, the OSX machine always prompts me for an SSL Cert to use, but with MD5 checkmarked as the only option in the 802.1x networking screen, this shouldn't be happening, making it more difficult to tell where this problem lies.The OSX machine keeps cycling through "Authenticating" and "Authenticating with MD5", and then settles on "AirPort has a self-assigned IP Address..." (meaning the laptop, not the AirPort wifi router)

Ubuntu Networking :: Cannot Connect To Secure Wireless Network

Jan 4, 2010

I have a Dell Inspiron 8600 laptop on which I recently installed Ubuntu 9.10. Most things work, but the wireless will not connect to my home wireless network (a Linksys WRT54G). (Cannot see any other WIFI antennas from here, so I don't know if it works on other networks). Ubuntu says I have an Intel PRO/Wireless 2200BG, Kernel Driver ipw2200.

When I try to look for a wireless network, Ubuntu doesn't see any. (Every other computer in the house does, Macs and PCs). I tried Connect to Hidden Wireless Network > New > and filled in the name and the WEP password that the Linksys gave me.When I select Connect to Hidden Wireless Network and select the network that I entered all the information for, the Connect button is always grayed out.

Ubuntu Networking :: Connecting To Secure Wireless AP In Jaunty?

Jan 13, 2010

My brother is trying to connect his laptop to his university's secure wireless network and is running into some problems.

He is receiving the following error messages with private info removed:

kern.log
=========
Code:

Jan 13 09:42:52 laptop kernel: [ 91.746454] wlan0: RX AssocResp from REMOVED (capab=0x421 status=12 aid=0)

[Code].....

Also, in my research it appears that people that have Wireless problems often install the linux-backports to see if this fixes the issue.

Ubuntu Networking :: Connecting To A Secure Wireless Network (WPA Or WPA2)

Sep 1, 2011

In setting up wireless connections I have ran into an array of problems. First, when I installed the new OS on my laptop I had to get the correct drivers and firmware for it to display and connect to any connections, had no problem here connecting to a secure wireless network (WPA or WPA2). I then installed Ubuntu on my desktop and had to find the correct driver for the Netgear WNDA3100v2 USB adapter, got it all installed with the Windows Wireless Drivers tool or w/e it is. This made all the available connections come up. I tried connecting with the WPA password I was given for the network and will not connect.

I had the guy managing the network change the one I connect to, to a WEP Passphrase Shared Key thinking this would solve my issue, still nothing. And also in doing so, now my laptop will not connect to the wireless network using the Passphrase. I do not want to go back to Windows, and I will be getting rid of my Lan connection soon so i need a solution to fix this wireless connection problem.

Ubuntu :: Wireless Will Not Authenticate (After 11.04 Upgrade)

May 11, 2011

My wireless setup was working perfectly in 10.10 but after the upgrade to 11.04 all went wrong, i can see the device yes, and I can see the networks but when I try to connect it asks to reinput the password. And if I try with Wicd it says "bad password" the thing is, the password is the same i was using in 10.10 and it cant connect to an open network either. I am a bit new at all this, but as far as I know I was using p54 drivers in 10.10. in order to make the dongle work i hat to install "linux-firmware-nonfree"... tried to reinstall it, but the same result. Tried windows drivers too with ndiswrapper, and the same result again.

Ubuntu Networking :: 10.4 - Cannot False Authenticate With AP

May 13, 2010

I'm on ubuntu 10.4 and Cant seem to falsely authenticate myself with my AP. I am trying to break a wep key on one of my older linksys routers; It continues to say this:

Code:
root@kevin-laptop:/home/kevin# aireplay-ng -1 1 -a xx:xx:xx:xx:xx:xx mon1
No source MAC (-h) specified. Using the device MAC (xx:xx:xx:xx:xx:xx)

11:39:24 Sending Authentication Request (Open System) [ACK]
11:39:26 Sending Authentication Request (Open System) [ACK]

11:39:42 Sending Authentication Request (Open System) [ACK]
11:39:44 Sending Authentication Request (Open System) [ACK]
11:39:46 Sending Authentication Request (Open System) [ACK]

Attack was unsuccessful. Possible reasons:
* Perhaps MAC address filtering is enabled.
* Check that the BSSID (-a option) is correct.
* Try to change the number of packets (-o option).
* The driver/card doesn't support injection.
* This attack sometimes fails against some APs.
* The card is not on the same channel as the AP.
* You're too far from the AP. Get closer, or lower the transmit rate.

root@kevin-laptop:/home/kevin#
I'm using an eeepc 701 it has an Atheros card and does injection. I have also tried it with backrack 4 and it works perfectly (it falsely authenticates with the ap and decrypts the wep key) I just cant seem to get it to work on ubuntu 10.4. Could it be a kernel issue? I found out that there is a bug in the new(er) kernel(s). If you use an older kernel (I used 2.6.31-14 which can be found here) and it magically works.

Ubuntu Networking :: Cannot Authenticate To WPA Network

Aug 22, 2010

I have a TP-Link Atheros-based USB card: TL-WN422G. It's listed widely as being compatible, but I'm baffled if I can make it work. I'm running an ndiswrapper (XP-64) driver, and that seems to be loaded and recognizing the hardware correctly. The system can scan and correctly identify our network, and other nearby ones, but when the WPA key is entered (correctly, I've triple checked), the "Secrets" windows just keeps popping up and no IP is acquired. I've installed and tried to configure it with wpa-supplicant, all to no avail.

I've attached below list of various outputs that I've looked at.

Ubuntu Networking :: Samba Server - Authenticate With Passwords?

Jan 2, 2010

True or False: If you have a user on your Linux/Samba machine with a password, example:
User = Bob
Password = Password0
And Bob is on an XP computer, where his username is also Bob and his password is also Password0, is it normal for Bob to go to:

\SambaServer, double click on Bob's share (valid users = Bob only) and Bob get RIGHT in without being prompted?

On my prior setup, the user HAD to log in. If they wanted auto login next time with their credentials, they had to check "remember password." But now it's as if Samba knows who they are. It's very strange. What's the normal behavior? Must EVERYBODY authenticate with passwords, or if the Windows credentials are the same as Samba does it just somehow auto-detect it and allow them through?

Ubuntu Networking :: Wusb11v4 Sees Router Cannot Authenticate Wep

Jan 17, 2010

I'm getting rather bewildered.

I followed these instructions to setup my wusb11 driver using ndiswrapper:

[URL]

But when I try to ifup the interface, I get:

DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 14
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3
No DHCPOFFERS received.

iwconfig shows that no essid is assigned, even though I have specified one in /etc/interfaces.

Then if I go through the desktop gui Preferences -> Network to setup my wireless connection, /etc/interfaces does not seem to change but iwconfig then reports the essid is assigned.

Anyway, on my default taskbar there is a wireless icon. Clicking on that shows the wireless access points in the area. I see my own. When I try to connect to it, it prompts for my wep key. I enter the key, it thinks, and then acts as if I'd entered the wrong key.

Specifically of course, I'd like this to get fixed so that I can happily surf the net again, etc.

But I also I'm wondering why it seems that there is a disconnect between /etc/interfaces and Preferences->Network. If I type in a WEP key in the gui, I would think that it should appear in /etc/interfaces.

I'm definitely a Ubuntu wireless newbie, and not very experienced at Ubuntu anyway.

Ubuntu Networking :: Cannot Authenticate With Routers BIOS From Server

May 14, 2010

I want to make changes on my router bios for my server I have to go to my windows booted laptop rather than just 192.168.1.1 right here at my server. I only have to do a 360 in my chair and I am at my laptop but I don't want to. Everytime I type the gateway ip it reads off the name of my router and looks fine. But I enter my authentication info and it just returns the login window blank... something ubuntu-side?

Ubuntu Networking :: Router Encryption Settings 10.04 - Can't Authenticate

Nov 27, 2010

Using a D-Link wireless router, trying to get it through the authentication process with the client through a D-Link DWA-125 USB wireless. When I set encryption to "none" on both ends, the router links up OK, but when I enter matching encryption settings on the router, and then in the driver data file (RT2870STA.dat) on the client side, I can't get it to authenticate. I've tried all possible combinations in the .dat file with no luck. I'm fairly well convinced that there is a bug in the .dat file settings, and that the wireless port setting need to be forced at startup through the /etc/networking/interfces file, or some such procedure, to override the settings in the .dat file.

Ubuntu Networking :: Not Able To Authenticate To Home Wifi / Resolve This?

Sep 1, 2011

I acquired an old Compaq Evo laptop and installed Kubuntu on it. Bought a second hand wifi card, a DEXLAN IEEE802.11b (Having Googled to check it would work with Linux).

It detects wireless networks fine, and is able to connect to open ones, but I can't log into the home network with the password which works fine for Windows laptops.

I've tried every configuration of the router I can find, and followed the advice at https://help.ubuntu.com/community/Wi...untu#EasySteps but with no luck. It just asks for the password over and over again without connecting.

Networking :: Unable To Authenticate My WiFi Connection / Why Is So?

Jan 23, 2011

I switched to the b43xx (lp-phy) driver, as opposed to the broadcom STA driver which I previously had. I have dell 8312b/g lp-phy(mini) wireless card.

I have the wireless detection, but when I attempt to connect to Fios WiFi it continuously asks for my WEP (I have the correct WEP and I have typed it in correctly) and fails to connect.

I've read about the driver and firmware on linuxwireless and kernel.wireless. org.

http://pastebin.com/w44Xbgw3 (lspci -nnk output)

Security :: Ways To Secure Sendmail Or Secure Alternatives To Send Mail

Dec 1, 2010

I'm an Oracle DBA and started working for my current employer about 4 months ago. This past weekend an alert re: FS space brought my attention to /var/spool/clientmqueue (full of mail re: cron jobs) and the fact that sendmail is not running on our Linux servers.I'm told that the IT security team deemed sendmail too vulnerable so we don't run it.Aside from FS filling up and missing notification of issues with crontab entries, I'm concerned that we may be missing notification of potential issues. In other Unix/Linux environments I've seen emails from the print daemon when it experienced problems with specific jobs.

Are there other Linux facilities aside from cron and lpd that use email to advise the users of possible issues? Are there ways to secure sendmail or secure alternatives to sendmail? My primary need/desire is to make sure that emails regarding issues on the server get to the appropriate users. Secondary goal would be to have the ability to use mailx to send mail out. There is No need/desire to receive mail from outside.

Fedora Networking :: Fc11: Broadcom BCM4322 Can't Authenticate

I can't get my Broadcoam BCM4322 to connect to a protected access point. I've tried the drivers from rpmfusion, and tried to build the module with the source+binary package from Broadcom, all with no luck. The failure seems to happen during the WPA negotiation.

I haven't tried connecting to an unsecured WiFi access point.

When booting this same laptop to Kubuntu 9.04, it can connect to secured, so it is possible under linux.

Ubuntu Networking :: Getting On My Secure Network?

Apr 20, 2011

I am running Maverick (desktop edition - don't like the netbook remix) on my Acer Aspire One AO532h. I can deal with not being able to print, but not being able to get on my secure wireless network is getting to be a bother.I have AT&T DSL and am using an AT&T 2701HG-B 2Wire Wireless Gateway DSL Router Modem. If I had known that this particular 2Wire router-modem was so crappy, I'd have bought my own and tried wrestling around with that.I recently secured my wireless network and had to change the encryption from WEP to WPA so my iPad could get on it. Both my Mac desktops, the iPad, and an old Windows laptop are working fine, but not my Acer (or my XBox, for that matter). I've searched and searched for a solution and called AT&T (no Linux support :), all to no avail.

When I try to connect to my network, it goes and goes and either says that it can't connect, or shows that I'm connected, but with no signal/net capability.

Ubuntu Networking :: Connect To Uni Secure Access Vpn

Aug 26, 2010

I used to be able to connect to my uni secure access vpn by navigating to the appropriate page, logging in and clicking "start" by "Network Connect" etc. etc.
After an update to firefox it had been failing, giving me a "session timeout" MsgBox. I have tried clearing history etc and reinstalling firefox. I have also tried different browsers with no success.

So, I have since upgraded to 9.10 and now I get "Setup Failed, Sorry" in the bottom left of the screen (where "Done" is displayed once a page has loaded)...

I am now trying a different approach. I have downloaded ncui-6.5R2.i386.rpm and unpacked it fine. I have tried running it, without success and have also run the diagnostic - I will post results below:

When I try and run ./ncsvc I get the following:

Code:
ncsvc> Failed to setuid to root. Error 1: Operation not permitted

So I did a sudo ./ncsvc , which gives:

Code:
mkdir(/root/.juniper_networks) failed: Permission denied

I am pretty sure that my password above is correct - I re-tried it and got the same message... I can definitely do, e.g., sudo apt-get update fine.

I then ran all of the tests available in ncdiag (./ncdiag -A) which gave the following info which might be useful

Ubuntu Networking :: Secure Remote Desktop With SSH FreeNX & DD-WRT?

Feb 1, 2010

For a Secure Remote Desktop on Ubuntu 9.10 here is how I did it using OpenSSH, FreeNX and a router with DD-WRT v24. Pic of it in use at bottom of post, transferring a file and remote desktop at the same time.

For the purposes of this guide I will use a Desktop as the Server (Host) which is at home. The Client will be a Laptop that I can use to control the Desktop remotely. First you should already be familiar with the Terminal which is where you enter commands (anything in a "Code:" box).

In Ubuntu it is in Applications > Accessories > Terminal In Kubuntu it is usually on the lower left taskbar and is called Konsole I am using Ubuntu so you may have to make some adjustments to this guide if you are not using Ubuntu. Installing OpenSSH (for the rest of this guide I will refer to it as only SSH)
