ssh
The ssh identity: Secure Shell. Every field and what is required.
ssh is the Secure Shell protocol (RFC 4253). The target is host:port (default 22). The step sends and receives raw bytes as hex, and the session persists across steps, so a solution can stage an exchange and continue it.
Write it in English
A step reads as sentences, the same byte-session forms as tcp: send hex "<hex>" (or send hex of "<text>"), receive <n> bytes, receive until "<hex>", port <n>, timeout <n> seconds, close the connection, and expect ....
Fields
ssh uses the byte-session fields from tcp:
| field | required | what it does |
|---|---|---|
send | yes | the bytes to send, as hex or hex "text"; empty when a step only reads |
recv | how many bytes to read at most | |
recv_until | stop reading once this hex marker appears | |
timeout | how long to wait, in seconds | |
close | end the session after this step | |
capture | pull a value out of the received hex for later steps |
Example
ssh banner
# read the SSH version banner
recv 4096
timeout 5 seconds
expect the response to match "5353482d"
