======SSH / rysnc without password======
make sure the same versions of ssh are on both machines (open version 3.1+ works best for HP-UX boxes) \\
need to configure client (machine connecting from) and server (machine connecting to) \\
on client:  create dsa and rsa public and private keys with the following: \\
<code>
cd ~/.ssh
ssh-keygen -t rsa -f ~/.ssh/id_rsa
ssh-keygen -t dsa -f ~/.ssh/id_dsa
</code>
this creates id_dsa, id_dsa.pub, id_rsa, id_rsa.pub - optionally can enter a 'passphrase' when prompted \\

on server: \\
<code>
cd ~/.ssh/
</code>
vi authorized_keys2 \\
copy the id_dsa.pub and id_rsa.pub from client into authorized_keys file \\
make sure permissions 644 on authorized_keys \\
Also:
<code>
chmod 0700 /home/<user's-home-directory>/.ssh -R
</code>

Repeat process for creating keys on server, and copy the .pub keys to the client's ~/.ssh/authorized_keys file. \\

Should now be able to connect without being prompted for password. \\

To restart sshd: kill running sshd process \\
now issue:
<code>/sbin/init.d/sshd
</code>

Or for Red Hat systems:
<code>
service sshd restart
</code>
