Well, looking at /usr/src/crypto/openssh/cipher.c, there is a "none"
in struct Cipher. But specifying 'none' in Ciphers in sshd_config, I
get "Bad SSH2 cipher spec 'none'." trying to start sshd.

Does anyone know if/how the "none" Cipher is really available? I need
ssh only for authentication when transfering backups, and encryption
makes a difference in transfer speed on slow machines...
