I added with adduser and added the user to the group wheel and gave password. it is on a other soekris. i does have a NanoBSD image. and i didn't reboot i used exit. en mogen we nederlands praten hier?How did you add the user? What command(s) did you use? Is this on that Soekris? If it has a NanoBSD image /etc/ (where the user database lives) is a md(4) filesystem, changes to it will be lost when you switch off or reboot.
No i cannot log in root and user. It says Login incorrectWhat happens when the user tries to log in? What is the exact error message?
To debug it: Log in as root again, and look in /etc/passwd. Is the new user listed in there? If no, then adding the user failed (or changes to /etc/ were lost). If yes, then read the line for that user and see what is missing.
cksum program. Then change the password for root to a really simple string (like abc). You should now see that the modification time of master.passwd is newer, and that the content changed. Then reboot, and see whether you can log in. Also do the same thing with a non-root user account. If you still can't log in, them something in the configuration of login and perhaps PAM is broken. I'm not an expert on the internals of that.
