Hi,

I know I can ssh login without password from a local to a remote. My question is how I can ssh without password from the remote to another remote. Say, I have three machines: A, B, C where A is the local machine. I use the same private/public key pair for all the login. What I can do are:

1. ssh from A to B.
2. ssh from A to C.
3. If I am sitting in the computer B (or B is local), then I can ssh from B to C.

What I am not able to do is:
After I ssh from A to B, I cannot ssh from the B to C. When I try to ssh from B to C, it asks me a passphrase.

I think that there are something missing that I do not understand.

Thank you for your help.

When the keys were created for B, no passphrase was was assigned.
That is why you can use ssh without be prompted for the passphrase.

When the keys for C were created, a passphrase was given to the keys,
hence you are prompted when you use those keys.

Notice that the passphrase is not the same as a password. If you're
prompted for a password, that means that no keys are being used.

The easiest solution would be to create another set of keys for C
and do not include a passphrase.
