[LIP] script to automatic login

Dear LIP,

how to write a script (perl,shell or awk) for
automatic login to remote host (do something on remote
host and come back).

I could do it with 'ssh' with public key setup.
still not useful .. i had to give password on prompt
for the first time when i was setting up the public
key for remote host.
then onwards it wont prompt.

I want to avoid prompt for passwd. (even for the first
time)
can a script enter the password automatically and
login to remote host.

Please help..

Alok
