Ejemplo

conn := SSHConn{Host: "192.168.1.100", User: "deploy"}
if err := SSHCheck(conn); err != nil {
    log.Fatal("no se puede conectar:", err)
}

Notas

Usa BatchMode=yes para fallar inmediatamente si requiere input interactivo (password prompt). ConnectTimeout=5 para no bloquear si el host no responde. StrictHostKeyChecking=accept-new acepta hosts nuevos automaticamente.
