[senthil_kumar_1]

Hi

Shalom,

You should consider a master/server protocol like NIS or LDAP so when you create a user on the master its created on all other systems.

These are tools designed for the job.

If you want to do it without these tools then follow this document:

http://www.hpux.ws/?p=10

Write your user add script to run the list and



while read -r systemname
do
ssh $systemname command
done < system_list


command is a script on each system that adds the user.

Hi,

If you have established password less ssh login between one source sever(where script being executed) and other servers(where users needs to be created), you can achieve this by simple shell script.

Hi,

For password less login, follow these steps.

1.Login to serverA as user1.

2.$ssh-keygen -t dsa
Press enter for all the questions.It will create the private/public keys
under $HOME/.ssh/
File names are id_rsa and id_rsa.pub

3.Now you need to copy the id_rsa.pub file content into ServerB $HOME/.ssh/authorized_keys file
ServerA#scp ~user1/.ssh/id_rsa.pub ServerB:/tmp

Login to ServerB server

ServerB#cat /tmp/id_rsa.pub >> ~user1/.ssh/authorized_keys

Make sure the following permissions on serverB.

Home directory should have 755 permission (users home directory)
$HOME/.ssh directory should have 700 permission
$HOME/.ssh/authorized_keys file should have 600 or 640 permission

Hi ahsan,

pls explain that script.

[Jeeshan]

Read the script.

There is commentary inside that says about the script.

Shalom,

There is little practical difference between the script posted and my link.

Its just a step by step guide to accomplish your goal.
