Reset all Passwords

nickyboy · 04-22-2006, 02:23 PM

I have a list of users and I'd like to reset all the passwords to the same - can do them all at once, if so how ?

(Samba passwords too) I'm using Redhat 3.

Thx

I dont think you can change them all in one command.

You could set them to 'null' using this command:
usermod -p "" username

How many users do you have?

assuming the list of users is in userlist (and that they are the same names as you want reset for smb) and that by reset, you mean to have no passwd reqmt during login, ie, no passwd reqd)

for user in `cat userlist` ; do
usermod -p "" $user
smbpasswd -n $user
done

note that the single quotes in the "for" clause is a single back quote, not the apostrophe to the right of the ";"

why would you want to do this? did you mean to remove the ability to login for users on the list? in that case, use passwd -l instead of usermod.

see man passwd, man smbpasswd, man usermod

Do you have the chpasswd utility on your system? From man chpasswd:

Code:

       chpasswd reads a file of user name and password pairs from standard input and uses this information to
       update a group of existing users. Without the -e switch, the passwords are expected to  be  cleartext.
       With the -e switch, the passwords are expected to be in encrypted form.  Each line is of the format

              user_name:password

       The named user must exist.  The supplied password will be encrypted as necessary, and the password age
       updated, if present

That doesn't help with Samba though... You can use apropos passwd to get a list of password related man pages.
