Hi All, Wishes!!
I need some help to prepare a script to copy the public key from admin host to multiple client hosts to make them login without password.

but, here if i run the script, for every client i need to enter "yes" and then "password" for each client.
please suggest me to automate the same without entering "yes" and then "password" for each host.
My scenario is as follows:
We have a handful of batch accounts that run our production jobs. Our users are able to use sudo to become that account. Also, because of other reasons, the passwords are also listed in an encrypted file that each team can see their batch ID. So, I have some users... (5 Replies)

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)NAME
ssh-keysign -- ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
EnableSSHKeysign to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_ecdsa_key
/etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host-
based authentication is used. Note that ssh-keysign is not set-uid by default on Mac OS X.
/etc/ssh/ssh_host_dsa_key-cert.pub
/etc/ssh/ssh_host_ecdsa_key-cert.pub
/etc/ssh/ssh_host_rsa_key-cert.pub
If these files exist they are assumed to contain public certificate information corresponding with the private keys above.
SEE ALSO ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)HISTORY
ssh-keysign first appeared in OpenBSD 3.2.
