Directly supply the encrypted password

thiyagusham · 01-14-2013, 07:55 PM

Hello to all ;

I tried to create encrypted password when creating a user.
My system doesn't support me. I googled more options to use -p with useradd. i am getting command not found error.

>> OS VERSION >>

PHP Code:



# uname -a 
Linux testorcl 2.6.9-42.0.0.0.1.ELsmp #1 SMP Sun Oct 15 14:02:40 PDT 2006 i686 athlon i386 GNU/Linux

I know this is outdated. I would like to work on OEL only. please help me how to resolve my problem.

# useradd -p user120 xxxx

That's because the passwd must come after the -p option

Code:

useradd -p passwdxxx user120

BUT as per here http://linux.die.net/man/8/useradd, it must already be encrypted.

You could use

Code:

echo plaintext | passwd --stdin user120

#useradd -p passwdxxx user120

Quote:

#echo plaintext | passwd --stdin user120
Changing password for user user120.
passwd: all authentication tokens updated successfully.

From oracle user i issue following command

Quote:

$su - user120

su: incorrect password

May sound daft, but what's wrong with :-
useradd user120
passwd user120

(I'm assuming you have root access).

Regards your command I believe it should be :-

# useradd -p xxxx user120

1. passwd: difficult to see what the problem is. Its worth noting Unix/Linux is case sensitive(!) for everything.
I'd suggest doing

Code:

passwd user120

as root and creating a very simple passwd eg abc for now, just to prove it.

As above, you can't use the useradd -p unless the 'password' you supply is already encrypted.
Use one of the other methods and supply the plain/non-encrypted version.

2. home dir; the usermod cmd edits the /etc/passwd file only. To create the dir (or move it if it already exists), you'll need the -m option. See man page http://linux.die.net/man/8/usermod
