ssh query string and password

Hi ,

I want to login with ssh without asking for password prompt . Like
when i login into some machine with ssh username@hostname i want to
add password in the query string itself (basically i dont want
password prompt) . Is there any way to do this.

Thanks,
Niraj Kumar

So it means that we can not write a script which will log me via ssh
command . My requirement is that every thing has to be in the script
and there should be no user interaction.

On the originating machine, say

ssh-keygen -t rsa

Save the key in the default file (~/.ssh/id_rsa) and do not use a
passphrase. This will create a file ~/.ssh/id_rsa.pub. Add the
contents of this file to the file ~/.ssh/authorized_keys2 on the
remote machine (i.e., the machine on which you want to log on).
Whereas the id_rsa.pub file is world readable, the authorized_keys2
file should only be readable by you. Use chmod to set the permissions
accordingly.

Intentionally no. This is a security hazard. If you really want to do
such a stupid thing, then use ssh-agent or use key-based authentication
with a passphraseless key (which is a lot more secure at least, than
password authentication in this case).

Creating ssh key with no password would do that.
ssh-keygen -t rsa and if it ask you for password leave it blank.

You don't pay attention. Use public key based authentication with a
passphraseless private key. This way there is no user interaction.

The other possibility is to use the ssh-agent, which will require you to
log in at least once manually, so it can cache the password for you.
This is probably even more secure, because at least the password won't
be saved on the hard-disk in this case, whereas the private key is a
file.

Why?
