SSH

VS Code Remote connects via SSH tunnels or containers, linking the developer's local editor interface with remote computing resources.

The SSH protocol was created in 1995 by Finnish researcher Tatu Ylönen, originally developed to replace the insecure Telnet and rsh protocols.

Ed25519 is a digital signature algorithm based on elliptic curves; compared with HMAC shared-key schemes, the receiver does not need to hold a secret that could be used to forge signatures, so the risk of leakage is lower, and signing and verification are fast with short signatures.

SSH key authentication is based on asymmetric encryption principles, where the private key is kept locally and the public key is uploaded to the server, with no password transmission throughout the process, making it more secure than HTTPS username and password authentication

The lifecycle of an ordinary SSH session is bound to the TCP connection; when the connection drops, the process receives a SIGHUP signal and terminates.

Termius是一款跨平台SSH客户端，支持Windows、macOS、Linux、iOS和Android等主流平台

OSC 52是一种可以通过SSH远程复制内容到本地剪贴板的转义码功能

The group's existing machines (such as a Fluent workstation or GPU cluster) can access CloscoScience by being registered as SSH servers, and a personal computer can also join the team as a host.

borg typically requires a writable SSH target for backups.

After connecting to another computer via SSH, Hermes cannot automatically bring the tools and operational capabilities already present on the host machine to the target computer; to operate software on the target computer, the corresponding tools must be installed or the corresponding MCP services configured on the target computer.

Programs launched via SSH on Windows do not necessarily appear in the currently visible desktop, and the desktop control component needs to run in the correct login session.

Triwarden supports storing SSH keys in the vault and using them for identity authentication and Git commit signing.

ZMODEM is a protocol for transferring files over serial connections (including SSH sessions); sz is used to send files and rz is used to receive files, reusing the already established terminal session rather than opening another connection.

`ssh user@remote_host tmux new -s remote_job` can create a tmux session on the remote host and start the task with a single SSH command.

On Ubuntu 24.04 LTS, SSH runs on port 22 by default.

Before enabling UFW, SSH must be allowed first, otherwise the remote connection will be cut off and can only be fixed through the cloud provider's console (VNC or serial).

The separate SSH remote auxiliary entry point has been removed, and SSH remote now runs the hub via an uploaded Cline CLI.

After an AI Agent connects to a remote host via SSH, it obtains a shell session in which it can execute arbitrary commands, able to read command output, determine the type of error, and decide the next action, forming a "perception-decision-execution" closed loop, which is precisely the core that distinguishes an Agent from ordinary code completion tools.

The developer uses a committed file, machines.json, to manage all machines, with each machine entry containing id, name, platform, SSH host, user and public key.

An SSH session forwards the shell's locale to another Mac that does not have that locale, causing perl to crash; the mac command now no longer sends any locale.
