I had no clue I installed an old version. Tomorrow I will try the new version and see if the authenticating works now. If so, I will obviously mention that here.

[Zenith]

To be more precise, I did it like this:

$ cd /usr
$ sudo tar xvzf nomachine_4.0.369_1_x86_64.tar.gz
$ sudo /usr/NX/nxserver –install

I have a i5-2400 and run Linux Mint 19.2 Tina Cinnamon (64 bit). So that tar.gz seems to cover both 32 and 64 bit packages it seems. Please let me know if I used the right version 🙂

Hey wsilva32,

Thanks for your reply. I’m a Linux newbie, so I might have done the same. How did you install NoMachine on your Linux machine? That way I can check and compare if I did something wrong as well 🙂

Thanks in advance!

So I DO need to change the SessionLogLevel to 7 in the server.cfg and node.cfg files and SessionLogClean 0 in the node.cfg file?

Also, since the update tab is under ‘Server preferences’ this still represents the player version (as well)? In that case it’s indeed version 6.9.2

[Zenith]

One small addition to my last post, what do you mean with: “with the latest NM 6.9.2 package as well” ? Just the latest version of the player? And if so, how can I check the version on the player?

[Zenith]

Do I also have to carry out these steps?:

Step 1 – Set debug level in server.cfg
Edit /usr/NX/etc/server.cfg, uncomment and set the following:
SessionLogLevel 7

If the problem affects web sessions, set also:
WebSessionLogLevel 7

Step 2 – Set debug level in node.cfg
Edit /usr/NX/etc/node.cfg, uncomment and set the following:
SessionLogLevel 7
and:
SessionLogClean 0

Btw, when reinstalling NoMachine server on my Linux machine I didn’t install additional (separate) packages. I also had a ‘great’ idea last week. I borrowed my parents laptop, which is pretty new and they hardly use it. I just installed a few programs on it for them. So it’s a pretty uncompromised laptop if you understand what I mean. I installed the player on that and yet again got the same ‘Authentication’ error. So it’s not my Windows machine it seems.

I will gather the logs on both machines like you said. The clean install of NoMachine on the Linux machine is left in it’s default configuration this time. I only have to know if I have to change the debug levels in the config file like the instructions mention on this page:

NoMachine works out of the box in the majority of scenarios

I would agree, the installation process and the software seems really straight forward. And only when I try to login on my Windows machine I have a problem. I feel it must be such an easy solution, because it can’t be (this) hard… I still think it’s a wrong username or password.

I re-installed NoMachine and everything went fine, up to the point of trying to log in on the Windows player. Again I get the error: “Authentication failed, please try again.”

I understand you can’t provide remote support for non paying users, but I thought I’d ask. You never know 🙂
If I would purchase the ‘NoMachine Enterprise Desktop Subscription for Linux’ for $44.50, would that entitle me to remote support?

For now I’ll first try to re-install and see if that fixes anything. Should I install the ‘NoMachine Enterprise Client or the Terminal Server Node package’ as well? Because I think I did do that last time.

[Zenith]

In the player in Windows I can’t choose anything else then NX, there are no other options. In the server on Linux I can’t find an option to change the protocol either. Although I’m quite sure there have been more options available in the past, showing on the ‘Server status’ tab. In the box under ‘Use an IP from the list to connect to this desktop’.

Now I also can’t even reach the login part in the player anymore:

The connection to the server was lost.

Error: Server is stopped

While the server is clearly running. I restarted the server a few times to see if that fixed it, but it didn’t. I also restarted the player a few, but that didn’t fix anything either.

 

In the auth.log file I see pam_unix entries, but nothing about ‘nx’ or pam_unix(nx:auth). The log mentions authentication failures and even ‘3 incorrect password attempts’, while like I said I couldn’t even reach the login part in the player this time…

So I will e-mail those auth.log files (there’s also a auth.log.1), the last one contains some errors about port 22 (SSH). This is because I tried to change the port manually, since I couldn’t change the protocol.

I also ran this command again: sudo /etc/NX/nxserver --debug --collect

And I will add this zipped package to the e-mail as well.

If this result in a solution, is there any change I could get some remote support? Because this is going on for more then over two months now.

Thanks in advance

Done! 🙂

Yes sorry, I didn’t see your first reply on the second page here before sending that. In the meanwhile I replied to your last email, it was send on March the 13th at 17:08 (5:08 PM I believe). Please let me know if you have received it!

Thanks in advance

[Zenith]

Can you please let me know if you got/found the e-mail and if I should send it again?

Thanks in advance!

[Zenith]

Hello Britgirl,

I did send the e-mail on 25 February 2020 on 14:53u (or 02:53 pm) to forum[at]nomachine.com and it’s marked as sent. I didn’t receive an error, so it seems it has arrived. I used this as title: ‘Can’t login “Authentication failed, please try again.” (Linux forums)’.

So I added the ‘(Linux forums)’ part to the title, could that be the problem? Should I send it again?

Please let me know, thanks in advance!

[Zenith]

Sorry for the late response, I was able to collect the debug archive this time. I feel so stupid for forgetting the forward slash before ‘etc’… complete Linux newbie here.

I mailed the files like you said, can’t wait for the response 🙂

Thanks in advance

[Zenith]

Thanks for the reply!

I tried the commands:

etc/NX/nxserver --debug --collect

and

etc/NX/server --debug --collect

since there’s no ‘nxserver’ folder in NX, just ‘server’. Both give me this outcome:

bash: etc/NX/(nx)server: No such file or directory

I also tried both commands with sudo in front of it, but that gives me this message:

sudo etc/NX/(nx)server: command not found

The only folder present in the ‘server’ folder (in etc/NX) is ‘localhost’.

 

I DID find the /etc/pam.d folder and found a file called ‘su’. So I copied that to a folder where I save the files needed to provide. But still no luck on collecting the logs from the Linux server… and since I doubt I have a root account or sudoer (?) how will I ever be able to collect the files/logs that you need to be able to help me out?

I CAN provide the files: nxd.log, nxinstall.log and su. Would that be of any help?

Thanks in advance
