Telnet password assignation

Hi all,

I want simply to add a password for telnet users. Until now, my "etc/passwd" file looked like :

root::0:0:root:/:/bin/sh

ftp:x:14:50:FTP User:/home/ftp:

--> no password was needed to enter telnet console !

For what I know about Linux systems, I must add a "x" after root to indicate that I want to assign a password :

root:x:0:0:root:/:/bin/sh

But where and how must the encrypted password be set ??

Can I simply create a shadow file and put the pass directly in ??

I was thinking about something like "etc/shadow"...

Thanks for your help !

    I think I found the solution by myself on Nios Wiki --> Login HOWTO :

    ---------------------------------------------------------

    Busybox -->

    Login/Password Management Utilities -->

    [*] Use internal DES and MD5 crypt functions

    [*] getty

    [*] login

    [*] passwd

    Core Applications --->

    [*] init

    [ ] enable console shell <== unselect this

    [ ] execute firewall rules

    [ ] process init.conf

    (Sash) Shell Program

    ---------------------------------------------------------

    Then :

    ---------------------------------------------------------

    Method 2, for Fedora, and others that don't have mkpasswd to encrypt password.

    Change passwd file, remove the 'x' for root entry

    root::0:0:root:/:/bin/sh

    ftp:x:14:50:FTP User:/home/ftp

    Boot nios2 uClinux, login as root without password needed. Then run "passwd", enter your new password. Now you can save the content of /etc/passwd on your nios2 uClinux.
