questions regarding ssh

two questions regarding ssh.

I am  logged in to a jumpoff box.  Can i  "carry" my autentication to the next box  without putting in my password again ?

Every time I ssh it ask me "do you want keep your key this time or ."  I just want to default to sshing to the box without a this question.  We have a lot of systems and liikey will not be going from the jumpbox to the target that often.

Yes, you can do ssh without entering your password every time.

You can setup a public and private key mechanism and this way you will not have to enter your password every time.  Setting it up is fairly simple too

When you enable your public/private keys on the host and the target, your source host is also entered into known hosts in the target machine.  You just have to say, "yes" for the first time when it asks you whether you want it save it.  Thereafter, you don't need to do anything.  You just say, "ssh hostname" and it would log you in with the current userID, provided the same userID exists on the target machine as well.

Setup includes the following steps:

1.  Generation of asymmetrical keys --public/private pair.
2.  Keeping the private key on the jump host and copying the public on the target machine.
3.  The public key is copied to the following file : ~userID/.ssh/authorized_keys
4.  Making sure the keys or the key folder has the right permissions.
5.  Doing the first ssh and typing "yes"

For the password less authentication FARZANI has suggested the correct way but If you want that while sshing any target system, the system should not ask "do you want keep your key this time or ."  . Then you can suppress that message with option -q

-q           Quiet mode.  Causes all warning and diagnostic messages to be suppressed.

ssh without prompting for password ,follow the below steps.

1.generate ssh key on source host
# ssh-keygen -t rsa
2.copy public ssh key to each destination host
