Server :: Can't Connect To Nxserver - Authentication Failed
Jul 21, 2010
If your machine is connected to the Internet, you'll probably want to disallow ssh password authentication (which is advised but not mandatory). Edit the /etc/ssh/sshd_config file and change/add the following lines:
PasswordAuthentication no
AllowUsers nx
Don't forget to restart the sshd daemon after making that change: service sshd restart I already have PasswordAuthentication yes in my file as I need it to login to the server through ssh. Do I just skip that line and only add AllowUsers nx mynxuser at the end? Also, I followed the rest of the manual and when I tried the client on Windows it failed: I put in a user and password to login but shouldn't it be using the key instead? I think the problem is related to the above due to:
Quote:
NX> 203 NXSSH running with pid: 1428
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
Using nomachine trying to setup an nxserver. Installed nx per these instructions. Checking the status looks like this.
Quote:
cynthia@cynthia:~$ sudo /usr/NX/bin/nxserver --status NX> 900 Connecting to server ... NX> 204 Authentication to NX server failed. NX> 110 NX Server is stopped. NX> 999 Bye.
I'm a noobie with nomachine and have no idea why the authentication is failing so I'm open to any suggestions. I've tried stopping and restarting both ssh and nxserver and I've tried regenerating keys. I can ssh to the host but nxserver doesn't work.
im unable to connect via nxclient to my remote desktop when i try i get this in the log
Code:

When I am trying to run the Xserver using the command startx I am getting the below mentioned error
xauth: creating new authority file /oracle/oracle10g/.serverauth.22555 Fatal server error:PAM authentication failed, cannot start X server. Perhaps you do not have console ownership?
Above mentioned is my configuration. when i try to connect client with SSH it is not sending a request for authenticating user to RADIUS server. what else configuration i have to do, or if there are any mistakes in my configuration
how much bandwidth does the nxserver client use? Some places have reasonably priced mobile broadband but they limit the Gb usage. As I have a server with unlimited bandwidth, I though I could coonnect to it through nxserver and just use the server via the connection...

I use snmpv3, and experiencing problem in passwords containing special symbols like "!". For Ex.: snmpwalk -v 3 -a SHA -A xxxxxxx!xx -l authPriv -u user -x DES -X xxxxxxx <IP address/Name of device> -bash: !xx: event not found I also tried using "" before "!" in passwords for ex. xxxxxx!xx, but then I have failed authentication.
I made a system in CentOS5.5. I used Tomcat6 and PostgreSQL. But I couldn't enter my system. There are some error. And I don't understand what kind of error this. JDBCExceptionReporter.logExceptions(100) | SQL Error: 0, SQLState: null JDBCExceptionReporter.logExceptions(101) | Cannot create PoolableConnectionFactory (FATAL: Ident authentication failed for user "postgres") "postgres" is username. Is anybody knows anything about this error message.
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?
Whenever I try to open a file using gedit as a super user in fedora 14, i get the following error (gedit:2975): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported ** GLib-GIO:ERROR:gdbusconnection.c:2270:initable_init: assertion failed: (connection->initialization_error == NULL) Aborted (core dumped) I've googled the problem, but nowhere comprehensive solution is said to be found.

I got a problem with my CentOS server. Somebody told me OpenVPN Requires different changes inside my firewall settings. That could be the problem why openvpn wont load..I receive this error on my CentOS panel when im trying to connect into the centos openvpn (with my winxp pc):
I was working recently on a perl program on our ftp server (box is running SuSE, I belive v9.3) designed to email a warning if the mountpoint to our backup machine could not be mounted. A couple of other programs, month-end critical, took me away from that for a while. I got back to it today, only to discover that I cannot even send the messages anymore (before, I could send, but I was having trouble interpreting the results I was sending).
The program is using MIME::Lite for its mailsending function. The actual error message I am receiving is
Code: Failed to connect to mail server: Invalid argument at ./organize_bks_2 line 174
The line in question is the actual $msg->send command.
I have good reason to believe that the environment for this has changed; during the time I was working on other projects, our office phone setup was replaced and refined with an ethernet-connected setup installed by the company that provides our mailing services (and presumably network services in general, although I do not know this for a fact). I know that we were having email troubles with some of our month-end scripts after that, which required our main server's DNS values to be changed...but those errors were not the same as the one I am getting on this machine.
Is this simply going to be as easy as changing the DNS settings on our FTP box, and if not, where is the best place to start digging for more information?
I want to use remote desktop viewer. Onse I try to use connect and press find the ip address, it gives me: Failed to connect to Avahi server: Daemon not running Also, after restarting it shows Network discovery is disabled.
Im having some problem with my DNS. We are using a Linux web server as one of our web server which runs some live websites.When I trying to get the status of the DNS (NAMED) it comes the following error :
The same error appears when Im trying to apply any changes on zone level for a selected doamin in WEBMIN. (Basically can't apply changes)
WEBMIN > Servers > BIND DNS servers > click a selected-domain.co.uk > Apply changes
But the server seems to be running without effecting any probelms to the sites or users. I have been searching weeks for this problem & couldn't find a solution. And also Please note that Im bit new to Linux.
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've been using synergy on Ubuntu 9.04 and windows xp.Synergy 1.3.1 on both machines.My problem is that the server keeps cutting out. It seems to happen a lot when I watch flash videos on the server machine (ubuntu). This is what the server side looks like:
Code:
NOTE: synergys.cpp,500: started server INFO: CServer.cpp,1141: screen "server" shape changed NOTE: CClientListener.cpp,127: accepted client connection
[code]....
I dont think I usually get disconnected when doing other tasks. Mostly only when watching flash videos. Sometimes it doesnt automatically reconnect, and I have to kill synergys and restart it.
I get this error ALL THE TIME after a reboot if I try to print. Going to the printing applet to add the printer does no good because Lucid is not connected to the CUPS server. I found that the work-around below fixes the issue for the current session.
Im a composer and I loaded up on some excellent applications for music creation and notation- so excited.. I start with Rosegarden. Failed to connect to JACK audio server. Try my other applications, same problem. Basically the JACK audio server just WILL NOT RUN (correctly). I can sudo it and press start, but still it wont "play with" the applications! Heres the error message from JACK (I also get related errors when I try to do ANYTHING involving music creation):
error JACK Audio Connection Kit -overall operation failed -unable to connect to server Here is the "fatal error" from MusE "Failed to Find Jack Audio Server" This is the JACK output:
