    Default NX Failed authentication NXSsh exit status 255

    Hi,

    Recently I get the error Authencation failure for user and therefore some messages in /var/log/messages:

    Code:

    I don't know why they are coming^^

    How can I fix that?

    thanks

    i'm not a networking guru, so this might not be helpful:

    did you edit the log replacing something else for 'username', or is it
    what you actually logged ?

    do you know someone at 84.62.15.147 (somewhere in Germany) who might be
    trying to interact with the No Machine Desktop Virtualization and Remote
    Access server you are running?

    did you not assign them a user name and password?

    btw, why are you running the remote access server?

    I replaced my username with username!
    Yes this was myself trying to connect via NX, my username and password is correct, via ssh I can login!

    Im running the remote access server to have remote access xD, mostly I'm using ssh but sometimes I need X-Server and therefor I use NX, which was working well...

    I think I know where the problem is, but I don't know how to solve it...

    I changed the Port of my ssd from 666 to 665 because of our buggy router(doesn't forward 666 but 665-.-), where I have to change it to 665?

    Ok I got it, hat to change sshd_port AND sshd_auth_port in /etc/NX/etc/server.cfg

    Thanks!
