|
|
|
|
a command to start a server and configure the local client to be able to
|
|
|
|
|
talk to the server.

|
|
|
- Encryption & authentication are handled via [`orion`](https://crates.io/crates/orion)
|
|
|
|
|
- [XChaCha20Poly1305](https://cryptopp.com/wiki/XChaCha20Poly1305) for an authenticated encryption scheme

## Examples
|
|
|
|
|
|
|
|
|
|
Launch a remote instance of `distant` by SSHing into another machine and
|
|
|
|
|
starting the `distant` executable:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# Connects to my.example.com on port 22 via SSH to start a new session
|
|
|
|
|
distant launch my.example.com
|
|
|
|
|
|
|
|
|
|
# After the session is established, you can perform different operations
|
|
|
|
|
# on the remote machine via `distant action {command} [args]`
|
|
|
|
|
distant action copy path/to/file new/path/to/file
|
|
|
|
|
distant action run -- echo 'Hello, this is from the other side'
