passwd

[j773303]

When I issue the passwd command, it always ask me to enther the older password and issue new passwd. Is it passible issue the passwd command, the auto enther the password by script or other ways?

[Steven E. Protter]

root user is not asked for the old password.

log on as root.

passwd

You will not be prompted for the old password.

You MUST be superuser to do this.

I use the normal user. And every month I need to chage the password again. Any other quick way to auto change password?

[Steven E. Protter]

No easy way.

passwd < input.file

input file includes the password twice.

This is completely insecure.

At least make sure you erase the input file when you are done.

I cant understand if u want to enter a passwd from script, y need of 'password' we can make it NULL or make it not force for password change.. or else i may not clear with your question,

[Rajeev Shukla]

The best way to do this is..
I have written an C program which encrypts the password (with the random first 2 fields).
You then use /usr/sam/lbin/usermod.sam command with -p option and source this password.
Totally secure..

Can you make an example how to use usermod.sam if I want to change user1 password? Thanks.

[Rajeev Shukla · Accepted solution]

First is to get the encrypted password.
say encrypted password for "test123" is iR1PEHS6Mybdg
Then just type
/usr/sam/lbin/usermod -p iR1PEHS6Mybdg
That will change the password of the user to test123.
I had posted that C program in one post but let me know if you want it.

I can use usermod.sam to change the user1 password in the root user mode. But the permission deny in the user1 mode? why usermode.sam can not executed in the normal user?

[Darren Prior]

This is because usermod.sam is a backend program for sam. It's not intended for use by normal users.
