Ubuntu Networking :: 3G/GSM Connection Using PAP Authentication With Ericsson F3507G & ModemManager
Jan 12, 2010
I tried to get my 3G connection up with my Lenovo Ideapad S10-2 and its built-in Ericsson 3G modem. Well, as I found out after some time of debugging, it didn't work because my network provider only accepts PAP authentication, and regardless of the configuration within NetworkManager, the ModemManager always tried CHAP authentication.
I guess this is because the dialog of selecting PAP, CHAP etc. seems only be used for pppd, but not for the internal setup of the 3G modem.
For the Ericsson (and possibly other modems), the authentication for a packet connection is done with the AT*EIAAUW command, which is hard-coded in modem-manager to use the defaults for authentication.
I patched my ModemManager to allow only PAP in the AT*EIAAUW command, and this worked out perfectly. You can find the patch below. Beware that this is certainly not something that should be included by default, only given here for reference.
Frankly, I don't know who to address to talk about a possibility to get this feature (authentication method selection) in the ModemManager in a clean fashion. I'd be happy to provide some assistance to improve the ModemManager. If someone could provide me with a hint who to talk to or what to do next.
For your reference: the "00010" in this case references a bit-field of 5 positions, whereas the bits mark the authentication algorithms (MS-CHAPv2, MS-CHAP, CHAP, PAP, NONE) respectively. So, 00010 enables PAP and disables the rest.

My Problem is following:

I am using ubuntu in my new office, and I can't get the network working. The "official" OS installed was a Windows, and it has a special "dial-up" app for the LAN connection (not wireless). My network admin is apparently not helpful, since he actually knows nothing about the internals for the "dial-up" app (he did not even ever heard of TTLS, PEAP, MD5, etc), and claimed that no OS except for Windows can work...
Well, I have tested various configurations with my Mac laptop, and apparently the LAN connection requires 802.1X authentication, and it's using a very weird combination "TTLS+PEAP+MD5" (if I check these options in Mac OS X, the connection works). However, in NetworkManager, I can't select both TTLS and PEAP, and moreover, TTLS does not work with MD5. So, is there anything I could try?
I recently installed the new Ubuntu 10.10. My Sony Ericsson M600i produces a window to enter a PIN to connect to the internet. The window reads 'The mobile broadband device Sony ericsson M600i requires a SIM Unlock PIN before connecting to the internet.' I entered my SIM PIN and the network disconnected, I'm not sure what to do now. The phone works with no PIN request on Ubuntu 8.10.
I am trying to connect a new Ericsson MD400 to my my computer but no way! I cannot make it work. I have tried all sort of advice e.i NetworkManager, ModemManager, HSOconnect, Ozercdoff etc. How do you really use NetworkManager?
Is it possible to monitor WiFi connections and identify who are connected through OpenLDAP? If so, how will authentication be possible? By the way, I'm open if OpenLDAP is inappropriate for such authentication purposes and scenario.
I didn't know that charging via usb for my sony ericsson mobile, w880i actually needs the SE PC Suite to be installed, cos, I used to charge it via usb cable, as mentioned, on my workstation, which is window based, it's kinda insignificant to me that the software has to be installed first.
However, I'm currently on the move, with my newly installed "netbook", I installed Ubuntu 9.10 on my twinhead efio 121A (which is good, no compatibility issue) and now, I just figured that, SE PC Suite does not have any linux version, but my mobile is already out of battery, and I desperately need to charge it,
I did run a lsusb, it doesn't seem to detect the phone, neither as usb storage, or as a phone, cos, I saw other people lsusb output, it's an item with "sony ericsson", but my output does not have such item. However, when I plug in the usb cable, it did prompt to ask me to choose between "file transfer" or "phone mode".
I have a weird problem with ssh, I am trying to ssh to a solaris server (sparc) running solaris 10 from my Ubuntu box and as soon as it authenticates the password it closes the connection. The box is located on a internal network in a wiring closet with no ability for me to access console but i still have a working ssh session from 2 days ago with what i'm trying to comb through settings and trying to resolve the issue. It also has 2 NIC's and I cannot connect to the either ruling out hardware problem. I checked if there is a limit of the number of active connections and the was no limit. I was able to connect mitiple session till 2 days ago (at one point i had on my machine 8 active ssh sessions to the same server).
Here is the output of ssh -vvv: Code: $ ssh -vvv -l user1 10.100.xxxxx OpenSSH_5.5p1 Debian-4ubuntu4, OpenSSL 0.9.8o 01 Jun 2010 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 ..... debug3: channel 0: close_fds r -1 w -1 e 6 Connection to 10.100.50.4 closed.

I'm trying to run Wammu with sony ericsson xperia x10 mini (usb cable), the SD card inside the phone appears but I can't get something like /dev/ttyACM to communicate with the phone.
(It's ubuntu, generic kernel with all stuffs and I had had a samsunng phone working in the past)
On host running; $ ssh -XfC -c blowfish user@guest_IP xterm$ /usr/bin/X11/xauth: error in locking authority file /home/user/.Xauthority X11 connection rejected because of wrong authentication. xterm Xt error: Can't open display: localhost:10.0 (hanging here) /home/user/.Xauthority is an empty file, just created. $ sudo ls -l /home/user/.Xauthority-rw-rw-rw- 1 user user 1 2010-07-19 03:16 /home/user/.Xauthority
Nor lock exists. The password is correct. $ ssh user@guest_IP xterm I can connect the guest.
while tampering with the settings for my wireless connection by right-clicking on the icon on the top menu i was originally asked for my password for authentication. i selected the option to remember the password for future sessions unintentionally.
how do i get it back to the original setting so that it asks for a password before allowing me into the editing screen? i tried preferences > system > authorisations > network-manager-settings, but it didnt work.
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.
I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error: Authentification has failed. As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.
I have two machines X , Y . X is running on runlevel 5 while Y is running in runlevel 3 , I am trying to connect from machine x to y using X11 forwarding using the following command.
ssh -X username@IP
But i have the following error message.
"X11 connection rejected because of wrong authentication"
Using Wicd and it keeps dropping out or telling me "bad password" when the password is in fact correct. I even know it works because the first couple of times it worked, but the connection wasn't sustained for more than a few seconds each time. My reasoning is my wireless is functional in Ubuntu, there's no reason it shouldn't be in Debian. Wireless network card is ASUS PCE-N13. Ralink driver is installed. WPA-supplicant is installed. Gnome Network Manager is also present, though I've heard that it doesn't support my particular situation.
I am running Ubuntu 10.04 LTS. I am trying to run a query browser for mysql but keep receiving the following error:
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.
Seismicmike here. My first post. I'll try to be as clear and concise as possible. For the sake of this post, I'm going to use 1.2.3.4 as a place holder for my public IP. On my web server, I would like to be able to access the /var/ftp directory through a web browser. I have successfully done so with Google Chrome, but I cannot access the directory in Firefox or IE. Both FF and IE ask me for authentication but then time out attempting to load the directory.
I suspect that there may be something up with switching to passive mode and/or that this issue may be more with my configuration of Firefox and not with the server (seeing as how Chrome works). Another possibility may be related to SSL. When I connect with FileZilla, I have to use the FTP over Explicit SSL/TLS option in order to connect. In any case I still would like to fix it. I would also like to avoid having to install FireFTP if at all possible.
Steps to reproduce (not that you can without my actual IP =J):
* Open Chrome * Go to ftp://1.2.3.4 * Enter username * Enter password
On Ubuntu server 10.10, with a relay smtp server with authentication via postfix; I keep getting 535: Incorrect authentication data. I'm sure my username and password is correct. Heres how I set up postfix: I created a file called smarthosts.conf in my /etc/postfix/ directory that contains the following:
[Code].....
my server uses plain text authentication on port 25. I would like to use security like SSL, but this particular server is unsecured.
I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
If I am running a script, let's say a install script. Is there a way to make Su repeat authentication rather then just returning "Authentication failed" and continuing the script?
I need to make a choice on what authentication protocol I want to use for Authentication and Authorization. I was looking at Radius and then literature suggested that Diameter was a better protocol. Keep in mind I need this on a hetrogeneous setup ( linux & windows together). Diameter seemed like a good fit until I discovered that the open source code no longer seems to be maintained ( C/C++).
I was also looking at Kerberos as an option though there is alot overhead with the server. SSL/TLS or EAP? I am looking for simple but secure and am new at the security protocols.
I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?
Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?
I have a problem with ldap client authentication in ubuntu. I am using rhel5 as openldap server and I configured ubuntu as client, when I am trying to login the following message is coming."su: Authentication service cannot retrieve authentication info. Sorry" But when I do search through "ldapsearch" command output is coming without any errors, Can anybody explain what would be problem.
At my workplace the wireless connection is open but once you connect you first need to authenticate on your browser to be able to use the internet.On Windows as soon as I open whatever page I get the login request.On Linux I open firefox but nothing happens, just get the usual error page like if I had no connection. The IP's I get as well as DNS seem ok, I even tryed to match them up with windows.I tried a lot but can't get to the login page.
I have question regarding AD authentication. Will Ubuntu workstation joined AD domain via likewise client authorize to TMG proxy directly without any utilities like ntlmaps and etc?
