    Hello,

    I have installed nomachine 4.2.7 version on linux and configuration looks good, However there is is problem in the authentication. I am able to connect the linux server from windows XP as it is through the error in logs as below;

    In nxerror.log:

    xexecPAMCheckCredentials: Authentication failed with error 6.
    Info: Connection from <IP port 1990 closed on Tue Oct 14 09:57:48 2014.
    /bin/bash: ck-list-sessions: command not found
    /bin/bash: ck-list-sessions: command not found
    /bin/bash: ck-list-sessions: command not found

     

    In nxserver.log:

    Please see the following thread:

    https://www.nomachine.com/forums/topic/authentication-failed-with-error-6

     

    If that doesn’t help, please send the output of the following to issues [at] nomachine [dot] com:

    1) /etc/pam.d/nx, /etc/pam.d/su, /etc/pam.d/system-auth, /etc/pam.d/sshd, /etc/pam.d/password-auth files

    2) output of the command (after reproducing the issue):

    sudo grep -r nxexec /var/log/*

    Thank you.

    So this is a different problem and should be dealt with in a new topic. https://www.nomachine.com/forums/topic/black-screen-when-connecting-to-red-hat
