# Pentesting SSH (port 22)

## When to Use
- Default port `22/tcp`; management/embedded services may expose SSH/Erlang-OTP on `2022`, `830`, `2222`.
- When `nmap`/banner shows `ssh`, `OpenSSH`, `Dropbear`, `libssh`, `wolfSSH`, or an `SSH-2.0-*` banner.
- For auditing crypto posture, authentication configuration, key trust, and known daemon vulnerabilities.

## Quick Enumeration
```bash
# Banner grab
nc -vn <IP> 22

# Host key fingerprint
ssh-keyscan -t rsa,ecdsa,ed25519 <IP> -p 22
