Your Homelab Behind CGNAT — Now Reachable for Free

If your ISP puts you behind CGNAT, you can't SSH into your home server from outside. VPNs work but add complexity. rcmd now has a free hosted relay — 3 servers, no credit card, no ports to forward, works from anywhere.

Stop Giving AI Agents Your SSH Keys

Your AI agent needs to run commands on your servers. The only credential most people have to give it is an SSH key: everything, forever, with no record. rcmd's answer is a token scoped to named machines, expiring by default, revocable in one command, with every action audited — now one command to mint, and an MCP server to plug into. Includes the two security bugs I found in my own audit trail while building it.

How I Made remotecmd 1.7× Faster Than scp Over a 77ms Relay

remotecmd routes file transfers through a WebSocket relay — which means a single TCP stream can't fill the pipe on high-RTT links. I spent two days reading kernel source, CERN GridFTP papers, and gorilla/websocket internals. The result: parallel TCP streams that auto-tune by file size, atomic header+binary framing in the relay, and gzip writer pooling. 50MB over 77ms RTT: 1.74× faster than single stream, 1.21× faster than scp. Here's what worked, what didn't, and why.

Your CLI Should Update Itself

I have 6 servers running remotecmd daemons. Last week I spent 20 minutes manually updating each one to the latest version. That's stupid. So I implemented the cli-update-spec: rcmd update downloads, verifies, smoke-tests, and atomically swaps the binary. No SSH, no installer, no downtime. Here's how it works and why every CLI should do this.
