Strands harness is the open-source, state-of-the-art, fully assembled agent harness. It's a complete, production-ready agent the moment you install it. Across six benchmarks it matched or beat other harnesses on accuracy while using 28% fewer tokens. You get shell, file, and web tools, plus context management, memory, and subagents, all tuned and ready to use.
Secure shell is a method to access a remote machine securely over an unsecured network. It starts with a TCP connection from the SSH client to the remote machine (SSH server). Both the machines exchange the SSH versions and negotiate crypto algorithms, and each side runs a key exchange protocol. The SSH server sends the public key and a signature, which the client machine verifies.
The host key is checked against the known_hosts file. Both machines derive session keys on their end and do not share them over the network. Then the SSH client starts authentication by sending the public key for login. The SSH server matches the public key in the authorized_keys, and the SSH client also signs the auth request with the private key and sends the digital signature to the SSH server. This completes the SSH authentication, and now the session is open for communication.
