turbossh 0.19.6

TurboSSH — SSH / Serial / SFTP / SCP / FTP / RDP terminal & automation toolkit for automotive & embedded (Python API, CLI, and a full PyQt5 GUI with a VT100 terminal).

TurboSSH

TurboSSH is an SSH / Serial / SFTP / SCP / FTP / RDP terminal and automation toolkit built on Paramiko — for automotive & embedded work, test automation, and everyday remote ops. It ships three ways in one install:

1. Python API — import turbossh for scripts and test frameworks.
2. CLI — turbossh …, fully argument-driven.
3. GUI — turbossh-gui, a tabbed multi-session terminal with a true VT100 emulator (htop / vim / top work), an SFTP browser, serial consoles, and RDP launch. Ships as a prebuilt Windows exe (PyQt5 baked in — no PyQt5 install needed, even on Windows ARM64).

pip install turbossh

Install

pip install turbossh           # API + CLI + prebuilt Windows GUI exe
pip install "turbossh[gui]"    # also installs PyQt5 to run the GUI from source

Batteries included: paramiko, scp, pyserial, keyring, pywinrm, and pyte (VT100) are pulled in automatically. Only PyQt5 is optional — the shipped GUI exe already contains it, so turbossh-gui works without installing PyQt5.

The GUI

turbossh-gui

• Session manager sidebar — saved SSH / Serial / RDP sessions (right-click for New / Open / Edit / Duplicate / Delete). Passwords live in the OS credential vault, never in plaintext. A Quick connect box filters as you type.
• Tabbed sessions + a + button; Split tiles several sessions in a grid.
• Menu bar (File / Edit / View / Session / Help) with icons — New session, Save output, Set up SSH server, Copy/Paste/Clear, Split, Check for updates…
• True VT100 terminal (pyte) — full-screen apps (htop, vim, top, less, nano) render correctly, with colors, a block cursor, and live PTY resize.
• 5000-line scrollback — wheel up to read old output; typing snaps back to the live tail. Save all output writes the entire session, not just what's on screen.
• Quick buttons — one-click slog2info -w, journalctl -f, dmesg -w, tail -f, plus Ctrl-C and Clear.
• Split SFTP browser under each terminal — navigate, upload, download, mkdir, rename, delete (transfers on a separate channel; the UI never blocks).
• Serial console — local, or on a remote RDP machine over SSH with a one-click Scan remote to list that machine's COM ports.
• 🖧 SSH server button — turn this Windows box into an SSH server, offline, from the bundled OpenSSH (see below).
• Check for updates — one click pulls the latest from PyPI and reinstalls.
• Settings — dark/light theme, terminal font + size, default baud (persisted, applied live).
• Crash-proof — all I/O on background threads; a startup failure shows a popup and writes a crash log; runtime errors are logged, never fatal.

Quick start (API)

from turbossh import SSHHandler, SSHConfig

with SSHHandler(SSHConfig(host="10.0.0.5", username="root", password="pw")) as ssh:
    print(ssh.run("uname -a").text)            # clean single-line output
    ssh.run("systemctl restart nginx", check=True)
    ssh.push("local.txt", "/tmp/remote.txt")
    ssh.pull("/etc/nginx", "./backup", recursive=True)

Connecting — local, jump host, RDP

# direct
cfg = SSHConfig(host="10.0.0.5", username="root", password="pw",
                host_key_policy="ignore")          # ignore = lab/reimaged devices

# through a bastion/jump (laptop -> jump -> target)
jump = SSHConfig(host="10.232.9.22", domain="CORP", username="user", password="pw")
cfg  = SSHConfig(host="10.120.1.91", username="root", password="pw", jump_host=jump)

host_key_policy	Behaviour
"auto" (default)	add unknown keys, reject changed keys
"ignore"	accept any key incl. changed — for reimaged/DHCP lab devices
"reject"	strict; only keys already in known_hosts

Auth is auto-selected: password, private key (+ passphrase), agent / discovered keys, empty-password accounts, or passwordless=True. Connects retry with backoff and reconnect automatically; a failed connect self-diagnoses (probes the SSH/RDP ports and explains why).

Running commands

r = ssh.run("ls -la", timeout=30, check=False)
print(r.text, r.exit_code, r.ok, r.duration)
ssh.run_many(["a", "b", "c"], stop_on_error=True)
ssh.sudo("systemctl restart app", password="pw")
with ssh.open_shell() as sh:                    # interactive send/expect
    sh.send("cd /var/log"); print(sh.read_until("$", timeout=5).output)

Continuous logs

ssh.stream("slog2info -w", on_line=print,
           match=r"error|fail", save_to="device.log", timeout=120)  # ANSI auto-cleaned
for line in ssh.iter_lines("journalctl -f"):
    print(line)

File transfer — SFTP / SCP / FTP

ssh.push("fw.bin", "/tmp/fw.bin")                 # SFTP upload
ssh.pull("/var/log/messages", "messages.log")     # SFTP download
ssh.push("./build", "/tmp/build", recursive=True) # folder, progress callback
ssh.scp_push("img.tar", "/tmp/img.tar")           # SCP protocol

from turbossh import FTPHandler, FTPConfig
with FTPHandler(FTPConfig(host="ftp.x", username="u", password="p", use_tls=True)) as ftp:
    ftp.push("a.txt", "a.txt"); ftp.pull("b.txt", "b.txt")

Through a jump host, transfers ride the tunnel automatically. Remote FS helpers: listdir, stat, exists, isdir, mkdir, makedirs, rename, remove, chmod, read_text, write_text, walk.

Serial / COM ports

# local port (device plugged into THIS machine)
from turbossh import SerialHandler, list_serial_ports
print(list_serial_ports())
with SerialHandler("COM5", baudrate=115200) as ser:
    ser.write_line("version")
    ser.stream(on_line=print, match=r"login:", save_to="com5.log")

# port on a REMOTE machine, over SSH/jump (COM = Windows, /dev/tty* = Linux)
ssh.serial_write("COM5", "version", baudrate=115200)
ssh.serial_stream("COM5", baudrate=115200, on_line=print, match=r"login:",
                  save_to="com5.log")

Port forwarding (tunnels)

# ssh -L : reach a remote service on a local port (e.g. a web UI behind the host)
fwd = ssh.forward_local("127.0.0.1", 8080, local_port=18080)
print("now browse http://127.0.0.1:%d" % fwd.local_port)
fwd.close()

# ssh -R : expose a local service on a remote port
rfwd = ssh.forward_remote(9000, "127.0.0.1", 3000)
rfwd.close()

Both work through a jump host and return a handle with .close() (or use as a context manager).

Keys & passwordless setup

from turbossh import generate_keypair
generate_keypair("~/.ssh/turbo_key")          # writes turbo_key and turbo_key.pub

# deploy it (ssh-copy-id) so future logins are passwordless
ssh.copy_id(public_key_file="~/.ssh/turbo_key.pub")

Automotive / legacy devices

Old ECUs / embedded SSH servers often use crypto modern Paramiko drops. Re-enable it:

cfg = SSHConfig(host="10.0.0.9", username="root", password="pw",
                enable_legacy_algorithms=True)     # old KEX/ciphers/host-keys
# fine-grained: disabled_algorithms={"pubkeys": ["rsa-sha2-512"]}

In the GUI, tick "Enable legacy algorithms" in the session dialog.

Confidential credentials

Mechanism	What it does
Secret	wraps a password; logs/reprs show ********; only .reveal() exposes it
mask()	redacts secrets from any string (applied to all logging automatically)
CredentialStore	stores/reads passwords in the OS vault via keyring — no plaintext
prompt_password()	hidden terminal input

Enable SSH on a Windows box (offline)

Run this on the RDP / Windows machine to turn it into an SSH server — so TurboSSH (and your scripts) can reach it, including the COM ports plugged into it. It's fully offline: the OpenSSH binaries (ARM64 / Win64 / Win32) ship inside the package, so it works on locked-down corporate networks where downloads are blocked.

From the GUI (easiest): click 🖧 SSH server in the ribbon. Choose:

• This PC — approve the Administrator prompt; it installs OpenSSH Server, starts sshd, opens the firewall, fixes host keys, and the GUI confirms when it's listening.
• A remote machine (WinRM) — install OpenSSH on another Windows box from here, fully offline: the bundled OpenSSH is pushed over WinRM and installed remotely. Needs WinRM (port 5985) reachable and a local-admin account on the target — handy for enabling SSH on an RDP machine without logging into it.

From the terminal:

turbossh-setup            # self-elevates, installs OpenSSH Server from the bundled
                          # ZIP (ARM64/Win64/Win32), starts sshd, opens firewall,
                          # generates + fixes host keys. No internet / Windows Update.
turbossh-setup --InstallPip --Port 22   # also pip-install turbossh; custom port

Or auto-enable a remote box over WinRM: SSHConfig(auto_bootstrap_via_winrm=True).

Tip: this is the "serve" step — do it once per RDP machine and you'll never have to remember to enable SSH by hand again.

Result objects & error handling

• CommandResult — .exit_code, .stdout, .text, .stderr, .duration, .ok
• TransferResult — .size_bytes, .duration, .human_speed, .files
• OperationResult — safe-mode wrapper: bool(res), .value, .error, .unwrap()

Raise mode (default): typed exceptions — SSHConnectionError, SSHAuthenticationError, SSHTimeoutError, SSHCommandError, SSHTransferError, FTPError, SerialError, WinRMError, CredentialError (all subclass SSHError).

Safe mode (SSHHandler(cfg, safe=True)): every call returns an OperationResult instead of raising — ideal for GUIs and long-running tools.

Full Paramiko capability

TurboSSH wraps the common operations with retries, structured results, and safe secrets — but it never hides Paramiko. Anything Paramiko can do is available:

• Commands / shells — run, run_many, sudo, open_shell, stream, iter_lines
• SFTP — full file operations + recursive push/pull with progress
• SCP — scp_push / scp_pull
• Port forwarding — forward_local (-L), forward_remote (-R)
• Keys — generate_keypair, copy_id (ssh-copy-id)
• Jump host / ProxyJump — SSHConfig(jump_host=…)
• Algorithm control — enable_legacy_algorithms, disabled_algorithms
• Keepalives, compression, timeouts, host-key policy — all on SSHConfig
• Raw escape hatch — ssh.client (the paramiko.SSHClient) and ssh.transport (the paramiko.Transport) are exposed, so any lower-level Paramiko call works:

transport = ssh.transport
sftp = ssh.client.open_sftp()
chan = transport.open_session()
# …anything Paramiko supports
