If SSH without passwords is what your after why not use key based authentication? Setting up keys is painfully simple.
Public key encryption Generating keys for server A (the one with the data to be synced) a...@a:~> ssh-keygen -t rsa Enter file in which to save the key (/home/a/.ssh/id_rsa): Created directory '/home/a/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/a/.ssh/id_rsa. Your public key has been saved in /home/a/.ssh/id_rsa.pub. The key fingerprint is: 3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a...@a Tell Server B to Accept the key 1.
