To set up passwordless SSH, there are three main things to do:
* generate a pair of public/private keys on your local computer * copy the public key from the source computer to the target computer's authorized_keys file * check the permissions.
You can repeat that transitively for "A->B->C". You can use the initial pair of keys everywhere.
See here for details:

Making life with SSH on HCL easier
Here is a very convenient way to set up the access to any machine directly instead of doing a cascade of SSH calls. Put this into your .ssh/config file :
Host csserver User kdichev Hostname csserver.ucd.ie Host heterogeneous User kiril Hostname heterogeneous.ucd.ie ProxyCommand ssh -qax csserver nc %h %p Host hcl01 Hostname hcl01.ucd.ie ProxyCommand ssh -qax heterogeneous nc %h %p
Now, you can do:
ssh hcl01
and you get logged to the node immediately.
