Every time we add a blade, getting passwordless login setup seems to be a pain as the master has to be modified to "know" about the node so we don't get prompted with do you know this key DF:ER:5R:etc. etc. and typically this is done quickly by doing ssh <user>@<newnode> and just answering yes (assuming the .ssh directory is just coming from a standard image).
Word has it there is a way to do automatic login so as we add blades, our goal is really just to discover that(some systems are starting to have that like cisco UCS) and then automatically add that to the slaves file. Does anyone know how to do passwordless ssh without publich key authentication OR at the very least tell the master to "trust" all nodes out there so it never prompts for the do you want to trust the key question? The authenticity of host 'dhiller ()' can't be established. RSA key fingerprint is 94:95:c6:70:9c:ce:48:ca:db:6f:ff:ab:95:47:01:11. Are you sure you want to continue connecting (yes/no)?
