Hi,
you can configure a publickey authentication with a null passphrase:

login IDA@SERVER1

SERVER1# ssh-keygen -t rsa -C "ssh_for_`whoami`@`hostname`" -f ~/.ssh/id_rsa
empty for no passphrase



SERVER1# cp -p id_rsa.pub authorized_keys.SERVER1
SERVER1# chmod 600 auth*
SERVER1# scp -p authorized_keys.SERVER1 SERVER2:/$PWD


login IDB@SERVER2

SERVER2# cat authorized_keys.SERVER1 >> authorized_keys
SERVER2# chmod 600 authorized_keys

IDA@SERVER1

SERVER1# ssh IDB@SERVER2
yes

(and viceversa)

hi ,if i understand this properly,ur trying to explain the key from my machine and polave it in the remote machine.And by doing this the need of expect script will no longer be needed right.c the problem is this in the remote machine scp has been disabled meaning the port is closed and for all the reasons the remote key is not responding to any keys,which now leaves me only one way to go and therefore i asked the above script question.
Anybody willing to share the ideas are welcomed and tell me whts wrong with the above script

[paolo barila]

expect can automate scripts that manually works

You should really listen to Pablo here. Using public key authentication would help you alot as you wouldn't need to supply the credentials upon every login.

There's also no need to open a new thread on this topic all the time.
