GuideLike many linuxjournal readers, I have also lived in today's very popular "tech nomads" life, between networks, from one access point to another, where we are in different parts of the real world and remain connected to the Internet and other networks we use on a daily basis. Recently I have found that more and more network environments are starting to block common ports such as SMTP (port), SSH (Port 22), and so on. When you walk into a café and want to SSH into one of your servers to do s
