Operating Systems HP-UX Automatic script to change the UNIX Password Post 302843608 by Manivasagam on Wednesday 14th of August 2013 05:03:32 AM

Once the password expires it will ask for new password when the user logging next time and he can able to change.

The issue is our user account is getting locked if someone change the password to other password.

So we are planning to change the password automatically before it expires.

passwd

1) the above command will ask for old password
2) then this will ask for new password
3) confirm the new password.

4) again we need to type passwd command to do the password change
5) and need to set to old password

we are planning to autoamte the same in UNIX shell scriping and planning to place the same in crontab of each user with some time period (may be 55 days once)

so that password will get changed before it expires and hope no one will try to change the password.

Do you think is there anyway to automate such scenario - your suggestion please ?

NAME
dxchpwd - Create or change password program SYNOPSIS
dxchpwd dxchpwd -r | -l dxchpwd [-r | -l] -q dxchpwd [-r | -l] -u username OPTIONS
If dxchpwd is invoked without any options, it is assumed that the current user's password is to be changed. The following options are also accepted: Tells dxchpwd that the password change is to be done for a Local user. This can be combined with the -u and -q options. Tells dxchpwd that the password change is to be done for a NIS user. This can only be done from a NIS master and can be combined with the -u and -q options. Tells dxchpwd to query the user for the user name of the account whose password is to be changed. Tells dxchpwd to change this user's password. DESCRIPTION
The dxchpwd command lets you change your password. When you invoke the dxchpwd command, the program prompts you for the old password and then for the new password. Next, the program asks you for the new password again, to verify that you have typed it correctly. Note that the passwords are not displayed on the screen. Your new password must meet the length requirements specified by the authorization database for the user whose password is being changed. If your system is running with enhanced security, you may have to choose a password from a list of randomly generated passwords or you may be prohibited from changing your password until its minimum lifetime has expired, as specified in the authorization database. EXAMPLES
The following example requests that the password be changed for user smith: dxchpwd -u smith FILES
Password file Protected Password Database dxchpwd executable SEE ALSO
X(1X), xdm(1X), passwd(1) dxchpwd(1X)
