I'm using an rsa 4096-bit keypair to gain passwordless access to a raspberry pi from another pi. If I use the private key on Windows with PuTTY, I am able to access the target pi fine. However, if I try to gain access to the target pi with ssh from another raspberry pi, I am prompted for a password for the key file. There is no password for the key, but if I just press enter, the following is returned (This is while using ssh -vv etc..): debug2: no passphrase given, try next key. How am I supposed to enter a blank password if it automatically skips to the next key when no password is entered?

Thanks in advance, Nathaniel

After posting this I just found a forum with a related problem. Since I generated the keypair on linux, you must do: ssh-keygen -b [NUMBER OF BITS] -C [COMMENT] -f [FILENAME] -P "". The important bit is the -P "", as it seems to ensure ssh does not require the user to enter a password when the key file is used.
