Go Ethereum (geth) is a software for Ethereum. geth doesn't provide secure networking and it should do this, as this kind of built-in functionality would increase complexity and add attack surface to critical blockchain node software. Fortunately, in UNIX world, you can easily combine different tools to work together. The solution to this particular problem is to use VPN/tunneling software for secure connections. The tunnel will expose the server local connections to your own computer. The most popular tool for this (available in every OS by default, nowadays including Windows) is [Secure Shell (SSH)][1].

[If you are not familiar with SSH please first read SSH tutorial how to safely do passwordless logins using SSH keys][2].

Start a node on server. When the node starts it binds its RPC port to localhost (127.0.0.1 in IPv4, ::1 in IPv6). This is so-called loopback connection that you can only access from the computer itself and not from external netwo

PSS = bzz whispered

pss (bzz whispered) is a swarm network service offering incentivised internode messaging using kademlia based deterministic routing.

phase 0 comes with priorities and an easy to use api exposed to RPC. you can subscribe to messages and peers using geths new pub/sub (available via websockets and ipc).

Swarm kademlia routing implements an efficient unicast address based messaging system. While whisper's architecture offers a nice trade-off between efficiency and anonimity, it is lacking the case when strong anonimity is not required, but predictably low latency transfer is. Public chatrooms, or convo between nodes that do not mind leaking this fact (the content is always safe due to end-to-end encryption).
