Hi Leaders,

I have to reset the password of almost 100 unix users automatically. Can you please suggest any script to perform this activity. Thank you in advance.

In their user profile, under settings,
there is usually a setting/checkbox to 'time limit' their password.

- forcing them to change it on a set/regular basis.

you may have to this change manually - on all those machines.

I've never used it, but I've heard sysadmins recommend ClusterSSH for tasks involving large numbers of machines.

http://sourceforge.net/projects/clusterssh/

also you can configure SSHPT, one of the great tool to maintain large number of servers.

Hi,

My question is to automatically pass the default password when we try to do the below activity.

$ passwd user01
Changing password for "user01"
user01's Old password:
user01's New password:
Enter the new password again:

do you mean you do not want to allow them to change their passwords?
there is a command to do that: passwd -l <user>

No. I have created 100+ unix users (for example user01, user02, ... user150 ect). Once the creation of users is done, we have to set the password for further login with the created user. For that we will issue the below command with root user at unix prompt.

$ passwd user01

This will prompt the user to issue the password and confirm password. Now, these two ( password and confirm password) should be updated with default password ( like happy1 ) without user interaction. for this I want the shell script. This is my requirement. Not sure how to implement. Requesting you to please suggest a way. Thank you in advance.

You can put this command in a file and execute that file-
give the file executable permission and copy the file on remote host and execute.

For more detail you can take help from this link - http://fclose.com/b/linux/3198/chang...-command-line/.

if you are using redhat based linux distro you can use this command


it will not give you another prompt to set the password

We are working on Unix with AIX6.1 and executed the command but its prompting for the password.

Could you pipe names and passwords to chpasswd?

I did a quick try and the following worked, so presumeably you could pipe a file to it:
Where me is the username and the password is set to the word password.
