Some stuff that's seldom used, but wise to remember.

Using OpenSSL to test STARTTLS connections

• openssl s_client -connect server.example.com:25 -starttls smtp

Reaching ssh host behind another without agent forwarding

• ~/.ssh/config:
  Host <name>
    Hostname <unreachable ip>
    <other options> 
    ProxyCommand ssh -q -W %h:%p <name_of_reachable_host>
