Hello. i hope somebody can help me, My linux machine doesn"t allow anybody to login anymore, when someone try's the machien reply's with "login incorrect".

I have try to solve it using the "single-user mode" but in that mode the filsystem is Read Only"so i cannot change anything.

Did you recently add that user? Or did you install the shadow-suite? Have a look at /etc/shadow. If it exists and the new user isn't added, have a look at /etc/passwd. If the user's located there, run pwconv.

Can I run pwconv while in single-user mode ?????

Why does it say that the file system is Read-Only ?????
vx

Commented:
The filesystem must be mounted as read-only. Type mount to check that. I'm not sure if you can run pwconv in single-user mode, but normally you should be able to.

Did you check whether the user is added in /etc/shadow or /etc/passwd?

okay, i have checked it, the command pwconv isn't available.....!


My machine gives me a error concerning the kernel version, the version kernel isn't the good version?????

Commented:
pwconv isn't available, but /etc/shadow is? Strange. The error message means nothing to me. What kernel do you run?

Check the amount of free memory on your HD. Can sou login as root in multi-user mode. Linux stops the login of nun superuser accounts if the amount of free memory on your HD gets low.
