Slackware :: FreeNX - Authentication Works But Session Fails
Jul 21, 2010
I installed freenx-0.7.3-i486-1alien.tgz on the server (with Slack 12.1), all according to instructions. I installed the no machine nxclient 3.4.0-7 on the client (with Slack 12.2). I ran setup and configured. I used the default no-machine keys, not custom ones. Since authentication failed at the beginning, I enabled DBauthentication, and added my user and password, which seemed to allow authentication to occur.
Here is my node.conf:
# node.conf
#
# This file is provided by FreeNX. It should be placed either into
# /etc/nxserver/node.conf (FreeNX style) or /usr/NX/etc/node.conf
# (NoMachine NX style).....

Does anyone know how to do a 'shadow' session with freenx client, qtNX?I don't see any options in that particular client to 'attach' or 'shadow' a current X11 session. Does anyone have a slackbuild for nomachines NX client?

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

I just tried FreeNX. I work great. I am thinking about uninstalling the vino/vnc on my machine.
However, I'd like to know if FreeNX can access the session that open locally on the server. I tried session 0 and 1, none of them can access the local session.
For default vnc, the connection will let you access the local session on the server. Can FreeNX do that?

I'm having some trouble with FreeNX on OpenSuse 11.2. I followed the instructions on this page to set up the server on my linux machine, and I'm connecting to it with the Nomachine client for Windows, running on Windows XP x64. It refuses to complete the connection, and the console log from the NX client is as follows code...
I've searched this forum and many web pages on google, but I haven't found anyone with this exact problem. the fact that it can't stat those files suggests to me that it might be a permissions thing, but I wouldn't expect non-root users to EVER have permission to files in any subdirectory of /var, so I sincerely doubt that they would release a program that requires read/write access to such files, and therefore, I am pretty certain it's a configuration issue, although I'm not experienced enough with the NX server to know where to start looking for the failure. Previous attempts with FreeNX and opensuse 10.3 (I am testing 11.2 for a possible upgrade of all of our linux systems here at my office) yielded totally successful results. the fact that there is no NX server included in the DVD distribution of 11.2 seems a little strange to me, as it was included with 10.3, but this is of little significance compared to my real issues.

I installed freenx on my desktop and decided to set up a custom key following this tutorial: [URL]
Code:
sudo dpkg-reconfigure freenx-server
Here I chose 'Create new custom keys' and SSH. After copying the client.id_dsa.key file to my laptop, I was able to log in no problem. However, I decided to check and used another computer (running qtnx as a client) to attempt a login with the default key.
It still worked.
Have I missed something in the fine print here? If not, is there a way to fix this behavior?

Im having some issues regarding AD authentication.
I have the PC running Ubuntu 8.10, it has likewise installed and is working great except for one problem.
We have currently two domains. One is called FS and one is called PIONEER. I joined the PC to FS, and can authenticate to FS perfectly (using FSuser at login), but when trying to Authenticate to PIONEER (using PIONEERuser at login) it just sits at the blank background and doesnt load the desktop at all.
What am I missing? Is there an conf file i need to edit?
Here is output of my auth.log when I try to log in using the PIONEERJpionner login
Code:
It looks as thought its not lauching the session.
Also, I am able to get in with PIONEERJpioneer using the failsafe terminal, but upon logon it gives me:
Then it acts normal.

For years, I've been using SSH with public key authentication to connect to a remote server, and my private key is formatted like this:

I've tried creating a new key which uses DSA, but I got the same result...
Does anyone know what the cause to this might be?

I am very new to this and tried searching for this problem in the forums but have not find anything. When I installed ubuntu (formatted HD), the installer gave an error but then seemed to proceed as normal and everything installed (from CD). However, when I boot up from Live CD all my wireless works fine (it detects networks, connects, etc.) When I boot up without the CD it says networking disabled and gives me no other options.

When I connect to my workstation via Real VNC Viewer 4 to Xvnc running on the workstation, and running "su -" I get authentication failure as follows:
So, effectively I cannot su when connected via VNC.
But if I'm at my workstation, I can su just fine:
Nov 18 16:24:30 localhost su: pam_unix(su-l:session): session opened for user root by xyz(uid=500)
Interestingly enough, I cannot su to my own userid over vnc, i.e. su xyz
In /var/log/secure I get:
I suspect it has something to do with PAM, but cannot figure it out.

I have an ssh (OpenSSH_5.1p1 Debian-6ubuntu2) client A and a server B set up for public key authentication as described in [URL]
The problem is the following: ssh asks for a password when connecting from A to B without any other ssh session going on between A and B; but if I connect from A to B whenever there is another ssh session between A and B, either I get prompted for the passphrase I used to encrypt the private key or I get logged automatically.
I already checked permissions on B: .ssh is 700 and authorized_keys is 600. I already tried "StrictModes no" in sshd_config. Printing debug information using DEBUG3 does not any useful insight. Moreover, there is no /var/log/secure (is it supposed to be there?)
Right now the computer is far far away from my reach, but when I configured the system I noted that whenever I was locally logged to B and then ssh'ed from A to B, I was logged in without any problem; whenever I was not logged in locally I was asked for a password. Note that at that time I was using a different public/private key pair whose private part had no passphrase.
how to know exactly what cipher is ssh/sshd using for a particular session? Is there a way to know any statistics for a given session (something like the ~s option in section 5 of [URL]
P.S. 2: does the following mean that ssh is using protocol 2.0 or something different than protocol 2.0?
(..........) sshd[2606]: debug1: Enabling compatibility mode for protocol 2.0

The first time PackageKit Update Applet ran, it asked me for the root passwordI accidentally pressed enter after making a typo, and ever since then Update Appletfails rror:Authorization failedYou have failed to provide correct authentication.Please check any passwords or account settings.Failed to obtain authentication. It never lets me input a new password. Two questions:1) Am I doing something wrong, or is this actually a bug? The possibility has been mentioned in other posts on the topic.2) Where does PackageKit store its files? I'll either change the password myself or delete the file where it's written, hopefully that will trigger PackageKit to ask again.

My first post here. I've been using Ubuntu to run our internal mail server for a while now on Ubuntu server 9.04 and ISPconfig 2. I've read a lot of threads on poeple that have difficulty connecting to their server using SSH from outside the LAN and it is not the same problem I have. Well, not entirely the same.
My problem is that my authentication fails from outside the LAn, but I can connect to the SSH port from outside my LAN. The other threads pointed towards checking the router port forwarding etc, but I can see my SSH log in asking for my username and password. So, at this stage I know the port forwarding worked, otherwise I wouldn't even see the log in prompt.
Has anyone see this before where you can connect, but the authentication fails? I can use the correct username and password from inside the LAN, but using the same credentials from outside fails.

One I cant figure out is a problem of authentication. I'm using open ldap server and try to authenticate a groupware (simple groupware) against it. As it fails, I tested with a ldap client to understand things better. Using GQ ldap client, I 'm able to browse my ldap tree successfully and to search some args from the base DN i specified. but when entering the exact uid as a search string iI got no answer whereas searching the cn returns the correct entry (and display its related entry including the uid I can't find ..) Here is the only thing I can trace in logs (syslog) when trying to seach firstname.lastname (= uid)

I recently upgraded my video card from a GeForce4 MX 440 AGP 8X to a GeForce FX 5500 AGP 8X. After that my 1360x768 monitor was stuck on a 1024x768 resolution. I ran system-config-display and under Hardware tab I changed the monitor setting from "Generic LCD Screen" to "1360x768 LCD Screen" with the acknowledgment that /etc/X11/xorg.conf file was been modified. After reboot the boot process stuck on:tarting kojid: Kerberos authentication failed. "Resource temporary unavailable" (11) [FAILED]I tried that with both 2.6.34.6-54 and 2.6.34.6-47 kernels available on my system.I use the latest KDE version available for Fedora.

I'm trying to connect to my Xubuntu box (zelda) remotely using my RSA key. I'm using Cygwin on my Windows box (link) to SSH in to the Xubuntu box. I've created the key and placed it in the authorized_keys file on my remote box. Here's where it gets weird. When I ssh into zelda the first time, it prompts me for my password. However, if I'm already connected to zelda and try to open another connection, it prompts me for my RSA passphrase. This is very confusing, and I have no idea what's going on.Here's my sshd_config file on zelda.
Code:
# Package generated configuration file
# See the sshd(8) manpage for details

I recently tried installing a new version of VirtualBox PUEL version, after uninstalling an earlier version. But the major issue I have now is that I can no longer modify my User Settings. Clicking on the "Autnenticate" icon gets me a failure notice: "System policy prevents modifying the system configuration", with details reading "Action: org.freedesktop.systemtoolsbackends.set". Hovering over this link says to click on the link to edit the file, but nothing happens. Searching the file system tells me this file does not exist. Prior to this episode with VirtualBox, I had no trouble modifying Users and Groups. I was able to remove a group from the command line, but the cannot get the GUI authorization to work. I have searched the forums and bugs for similar problems, and, although there appear to be a number of similar issues, no where can I find any clear information on how this system is supposed to work, or what I need to do to correct the problem.

Basically, the problem is, we have a bunch of computers in a computer lab, that we want to students to access, but not modify in ANY way. That includes backgrounds or whatnot. And after restart, any changes they may have made, change back. Also, they can't have read access to the administrator account on the computer.
This needs to give a permission denied, or something:
Code:
cd /home/(admin account username)
ls
The Guest Session is exactly what we are looking for, but try as I might, I can't get it to work. Because, we don't want to have to login as administrators, then activate guest session, just for our students to use the computers. The idea being, we can leave the computers in there, and not worry about the students breaking anything.
One thread I tried was: [URL]. However, using his method, will log the student into the account, and after about 5 seconds, log them back out.
The other method listed lower in the thread,
Code:
/usr/bin/guest-session
Seems to work, but upon logging out, fails to launch the gdm
Only way to restore is restarting the computer.

I just upgraded my Ubuntu 8.04 server to 10.04 and now I cannot receive mail on my Ubuntu 10.04 Evolution client, although I can send mail. No errors appear in auth.log or mail.log when I attempt to log in from my Evolution client, in fact mail.log shows 'pop3d-ssl: connection' from my laptop IP, followed by 'pop3d: Disconnected' when the log-in attempts fail.
I'm able to ssh into the server using the same log-on and password as before the upgrade, however I haven't changed the public or private keys in my .ssh directory. I updated the ssl keys in /etc/postfix/ssl but wasn't able to receive mail before or after the update.
The error in the client reads: 'Unable to connect to POP server mail.mydomain.com, error sending username'
I ran this test and the output appears to be related:
Is the pop3 server not running TLS? /etc/postfix/main.cf says it should, and I get no errors restarting / reloading postfix.
I am receiving messages in /home/user/Maildir, but I cannot download them.
I checked for supported authentication types in my Evolution client - 'Password' is the only one supported, as was true before. The client is not using any certificates.
The output of openssl s_client -tls1 -connect 127.0.0.1:995 shows 'certificate has expired' on the 'Verify return code' entry, not sure if that's significant.
What's different about incoming versus outgoing mail authentication?

At home in Guangzhou, I have no problem connecting to a WPA-secured wireless router.Now I'm on vacation in another city trying to use a dLink DI-624 router. If I connect immediately after reboot, no problem. If I suspend the session and then wake the machine up again, it will try to connect and then tell me WPA authentication failed.This happens both with network manager and wicd.sysinfo says the network controller is an Atheros AR9285 (ethernet is Realtek RTL8101E/8102E, probably not relevant).Since everything works correctly with routers other than the dLink, I'd have to guess it's not a general wireless configuration problem, nor a wireless card malfunction. Maybe some bad handshaking that manifests only after waking from sleep?More out of curiosity -- I'll only be here for a few weeks and a wired connection is readily available. But, say I end up in a hotel somewhere that uses dLink for WiFi

I got a workstation with openSuse 10.3 pre-installed. After I did the Online Update from YaST2 and rebooted the machine as requested by YaST2, the system came to fail starting up an X session.
Below are excerpts of the message appeared on the screen at the end of the boot process. (I transcripted it from the screen by hand.)
Code:
Waiting for mandatory devices: eth1 __NSC__
10 9 8 7 5 4 3 2 1
eth1 devices: Intel Corporation 82573L Gigabit Ethernet Controller
eth1 DHCP4 client (dhcpcd) is running
[Code].....
what is causing the failure of the X session and how to fix the problem? I would be glad if you give me any hints or pointers.
