*Hi, I ve forgotten my root passwd on centos 6 (red hat based), I tried to change it as I used in debian (in debian it works perfectly) , that is:
use a cd live (or installation cd1), to access the hd, I mount my root partition and mount proc and devices I tried the command passwd, no error reprorted, but after reboot the passwd had´t changed. then I decided to remove passwd from /etc/shadow (delete the second field). OK, now I can access my machine without passwd, BUT I CAN´T GIVE ANY PASSWORD!!!! I RECEIVE THIS ERROR # passwd* *Changing password for user root. New password: Retype new password: passwd: Authentication token manipulation error any idea to fix the problem. thanks a lot *
