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"
Both servers are running RHEL 4.7
I am running Ubuntu 10.04 LTS. I am trying to run a query browser for mysql but keep receiving the following error:

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.

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?
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

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!

View 1 Replies View RelatedThis is kind of a double question thread and I'm hoping they can be resolved together. I'm running Debian wheezy and I modified my /etc/apt/sources.list file to include "contrib non-free" on the ends so I could install flashplugin-nonfree for Chromium. After an apt-get install flashplugin-nonfree, I notice the error of:
ERROR: sha512sum rejected install_flash_player_10_linux.tar.gz
I tried to go to a video streaming site and I get the typical message saying I have a missing plugin. So I uninstalled flashplugin-nonfree and tried to go another route of getting the flashplayer-mozilla package from "http://www.debian-multimedia.org wheezy main non-free" hoping that might work. I installed their GPG key from here and did the apt-get update and apt-get install flashplayer-mozilla. I noticed that it would pull in tons of dependencies requiring about 250MB. I backed out of that and removed those lines from my sources.list file, trying to go the original route again. Now I'm stuck with that GPG key installed and I don't use that repository.
So my question is, how can I get flashplugin-nonfree working with Chromium, and how can I remove the key I installed from the .deb package from debian-multimedia.org?

i have been running Ubuntu for about 3 days now, finally getting all my files moved back to the drive and what have you.I came from running windows, and an Android phone with full su access, and done up all custom-like..I am loving the speed, etc. great experience so far.

I was having a problem with the keyring asking me for a password after I changed my user password. I googled it and found that since the password changed, I will get asked for the keyring password until I delete ~/.gnome2/keyrings/login.keyring. What happened was that I wasn't paying attention that you had to generate a new keyring password before rebooting.
Now, whenever I try to login via gdm, I get this message: error initiating conversation with authentication system - general failure
How do I get it working again? I can still login from the terminal.

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 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:

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.

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.

If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> I was hoping I could just plug in both cards and do this dd if=/dev/sdb of=/dev/sdc to copy everything and have a back up SD card.
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.

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.
