I want to use nomachine, instead of freenx, and well it isn't working. SSH server works and all, because freenx works., same for neatx. But I hear with nomachine you can see the main display of the computer? Is this true? Well one way to find out, but whenever I try to login I get: Authentication failed for user x. I don't know why, neatx and freenx worked, even x2go, but not this.

I'm trying to restrict command line ssh and yet keep NoMachine working, so I followed this post [URL]... and tried adding this to /etc/ssh/sshd_config:
AllowUsers nx@*.*.*.* paul@*.*.*.* *@::ffff:127.0.0.1 *@127.0.0.1
On restarting the ssh daemon other users can't login by the terminal, but I can. However, NoMachine won't log me in. I get: NX> 502 ERROR: Public key authentication failed. As a server side check:

I just finished following the instructions found here to install FreeNX on my ubuntu 10.04 server. It went smoothly, just used the default keys.Once I had that all set up I scrolled down and followed the instructions to set up the client and that went fine as well.My problem is with actually using the program.When I try to log in I get the error "Authentication failed for user tony" (my username). Do I need to change anything in the configuration other than setting it to use gnome and putting in the host address?oes it make a difference that my ssh settings only allow rsa login? I logged into the server with ssh to see if that helped but it did not. I even tried using the ssh key with the FreeNX Client but that did not work

Which user am I supposed to log in with? Is it the same user as I use on the server or is this a separate nx user? When I receive this message is it because of the user or the ssh key I use?
I inherited this shop. NIS is working fine... and has for years with one exception.One user named jpeters (not really ... just made that up) couldn't ssh into the network but she only had problems ssh'ing into one server named frodo (nis client). Other users were / are able to ssh into frodo so I know the daemon is running. (I saw the other thread that sounds exactly like my problem - but the solution didn't make sense because I don't have any other domains. Oh and I do *not* have sldap running anywhere.)When jpeters ssh'd into frodo it failed: "permission denied."Jpeters can, however, ssh into all the other NIS client servers. On the problem box, frodo, if I: # ypmatch jpeters passwd frodo returns the info stored on the NIS Master (gandalf). I verified this from several other servers too. All are pointing to the NIS master.
Then I discover that jpeters also has a local user account on frodo. I deleted (userdel) her from the local users on frodo. While this *did* successfully remove her record from frodo's local /etc/passwd file it didn't remover her from the /etc/group
Question 1: Shouldn't userdel have removed her group entry?
So I then used vi to manually remover her from frodo's /etc/group.But, still, she couldn't ssh into frodo and I'm tempted to tell her to STOP trying to ssh into frodo ..., but then I noticed that, unlike the users that are successful at ssh'ing into frodo, user jpeters belonged to several groups including "wheel." So I changed this in the /etc/groups on the NIS master server so she no longer belongs to the wheel group.She still could't ssh into frodo though. I then ssh'd into frodo as root. and as root I su'd to jpeters:
# su - jpeters
# yppasswd
but now something is different - I'm jpeters now and I when I entered jpeters password to authenticate the password request change, NIS *did* recognized her password!
I then changed the password and the changes were successful. jpeters can now ssh from all the servers including frodo.
Question 2: Do you think that taking jpeters out of the wheel group resolved the problem? Or did I just forget to make or restart or rebind something...
In trying to troubleshoot this problem I've learned a great deal but I'm also confused because as I said, NIS is working yet many of the things that people in the forum said to check aren't there for example:
# ypcat ypservers returns nothing
Question 3) how can this work if ypcat servers returns nothing?
Question 4) why does my passwd file on the nis server contain encrypted password for some users? Most have x in the password field but a few have gobbledgook. All the users that I have personally added appear this way. What am I doing wrong? And how do I fix it?
I have 2 servers A & B. both installed on different locations. both can ping and traceroute each other but there is no load shareing (both performing same functionality but independently). when i checked of server B /var/adm/messages, i can see that server A is trying to connect to server B but getting failed. and this is going on for long time. i mean it's not like someone manually try to enter but automatically its happening. i have already checked in cronjob but there is nothing. here are the logs,

I've been using Ubuntu since 6.04, not a linux guru by any means but can usually get myself out of trouble.
So, the issue... I installed 8.04 on my mother's laptop some time back as she was having trouble keeping Win 2000 running (she has a low spec no-name generic laptop btw). I live in Autsralia and she in England, i thought i could better support her if she was running Ubuntu... All has been well with 8.04 but with the new LTS release (10.04) i thought i'd talk her through the upgrade... Did the online upgrade via Update Manager, all seemed to go OK but when she went to log on after restart she got an error saying 'authentication failed' even though we are 100% sure we have the user name and password correct... Tried to do a ctrl+alt+F1 to by pass the GUI log on but couldn't get the terminal session to open up, just got a black screen - no command prompt.
So... thought OK re-install... downloaded the ISO, burned and sent her a CD in the post... talked her through the re-install, all seemed to go well (again) - BUT, after restart, couldn't log in "authentication failed" again...
So, remember i'm trying to talk a novice through all this... any thoughts!?!
If i can get her to log in i can then support her via some kind of remote sesion or other screen share... and it wont cost me a small fortune in international calls!!! But if i can't get a log in, i'm dead in the water!?

I apologize first because I do not know if this is the right section for my problem, but I could not find anything more suitable. I have an Asus 900 with Ubuntu Netbook Remix 10:04 In a nutshell: I realized today, trying to install a new program with Ubuntu Software Center, that I can not anymore authenticate myself as root. Of course I have not changed the password, but the old one is not anymore accepted ("Authentication failed").
The interesting thing is that I can install programs without problems (using the same old password) with the package manager in Administrative Tools (synaptic). Here, the authentication works well. Opening a terminal, I can use sudo to run any command by providing my password, with no problem at all. Following some guides found on the web, I reset the root password (supplying the same one as before) and everything went well. Only .... nothing has changed! Ubuntu center software authentication always fails.
What could have happened? Maybe I did some mistake by editing /etc/sudoers to solve another problem some days ago. Ubuntu told me that my username was not in the sudoers file, so I resolved it by adding to /etc/sudoers the line myusername ALL = (ALL) ALL
I checked the contents of the file and, apart from this line added, it is as it was before (I compared with that on another PC with Ubuntu). Can anyone make some sense out of it? Starting from the fact that the package manager does function ... but software center does not.
the laptop of my friend runs ubuntu through wubi. The system suddenly freezed and she restarted it manually. After doing a check disk and automatically repaired some packages(unfortunately she doesn't remember what exactly, only just inode information appeared), she can't log in as when she types her username and password the answer is authentication failed. We tried to change the password through recovery mode but nothing happened.
1. Do you have something to propose to solve the login problem?
2. If not how can i access and back up her ubuntu documents through windows?
I have just installed Fedora 15 on my laptop, Now i am trying to install some programs like .... skype, drivers to my printer etc but i get this message: Failed to obtain authentication.... when the installer is trying to solve dependensies...

View 2 Replies View RelatedEarlier today I was setting up ssh on a new computer. I modified permissions on the Passwd folder to complete the setup. I few hours later when I went to sudo something in the terminal I received the notice of an incorrect password (after using sudo prior to this), even though it was typed correctly.
I tried to restart the computer to solve the issue, but was met with an Authentication Failed message, regardless of the user I tried to log in with. I was hoping I could log in with recovery mode but was unable to do that as well. I have searched a substantial amount and have not found a solution. Could this be an issue with permissions on either the Passwd or Shadow folder? If so, could these be changed if I ran a Live CD?
I have a problem updating packages when using the kpackagekit systray notifier, it fails with the error "failed to obtain authentication".I've looked around and can't find any log output of this.If i start kpackagekit from the menu it all works fine, but not this way.This is with kubuntu 10.10, upgraded from 10.04, it did actually work before.
