If you can log-in to a host with password, you just &apos;ssh-copy-id myuser@thishost&apos;, supply the password once, and from that moment you can ssh with public key authentication. Extreme magic.&lt;p&gt;Also, sshfs works great, but has some issues with memory mapped files that silently lose writes. Luckily (?) most programs don&apos;t use mmap to write files, so it&apos;s not very noticeable.&lt;p&gt;All in all, ssh is one of the greatest tools.</text><parent_chain></parent_chain></comment><story><title>SSH Tricks</title><url>http://tychoish.com/rhizome/9-awesome-ssh-tricks/</url></story>
