htb-terminal

Python terminal client for selected HTB Labs API workflows (v4 and v5): machines, VPN, OVPN files, and raw API calls. Zero external dependencies.

See the command reference for every command, option, default, and the API endpoint each command calls.

Screenshots

Compact active-machine output keeps the session details and profile-only status text readable without dumping the full HTB profile.

machine active --oneline collapses that into a single status line.

Tables use compact columns, terminal colors, and truncation by default. Use --wide when you need full values.

user info shows your rank, points, and owns at a glance.

speedrun shows a live, per-step status while it connects the VPN, sets the MTU, and spawns the machine.

These images are generated with scripts/screenshots.py (see Regenerating screenshots).

Installation

Requires Python 3.10+. This project has no external dependencies.

Install as a global command with pipx (recommended) so htb is available from any directory:

pipx install htbx
htb --help

Or with pip:

pip install htbx
htb --help

The package is published on PyPI as htbx; it installs the htb command (an htbx alias is installed too). To run the latest from source without installing, use a clone:

chmod +x ./htb
./htb --help

Only speedrun has host-network prerequisites: Linux, OpenVPN, and the ip command from iproute2. vpn connect also needs OpenVPN, but elevates only that process by default.

Authentication

Generate an App Token from your HTB profile settings, then save it once with init:

htb init
# Paste your HTB App Token (input hidden): ...

htb init --check   # also verify the token and print who you are

init stores the token in your user config directory (~/.config/htb-terminal/token, or $XDG_CONFIG_HOME/htb-terminal/token) with owner-only permissions, so a pipx-installed htb finds it from anywhere. You can also pass it non-interactively:

htb init --token "$MY_TOKEN"
echo "$MY_TOKEN" | htb init

The token is resolved in this order, first match wins:

1. HTB_API_TOKEN environment variable.
2. --token-file PATH, when given.
3. ./api.token in the current directory (handy as a per-project override).
4. The user config file written by htb init.

When speedrun is run through sudo, lookup additionally falls back to the invoking user's default ~/.config/htb-terminal/token via SUDO_USER.

api.token is gitignored; never commit your token.

Examples

Full details for each command are in the command reference.

./htb machine active
./htb machine profile "BoardLight"
./htb machine list
./htb machine list --retired --page 1
./htb machine list --sp-tier 1
./htb machine search board
./htb machine search kerberos --all --limit 10
./htb machine search "breach creds" --all --profiles

./htb machine start "BoardLight" --mode auto
./htb machine start 444 --mode play
./htb machine start 478 --mode spawn

# Seasonal release: keep retrying a full spawn server, then wait for the IP.
./htb machine start Nimbus --mode auto --wait --retry-for 360 --interval 5

./htb machine stop
./htb machine reset
./htb machine extend
./htb machine submit 444 HTB{flag} --difficulty 50
./htb machine active --oneline

./htb user info

./htb vpn servers
./htb vpn servers starting_point
./htb vpn switch us-free-1
./htb vpn switch 'US Machines VIP+ 1'     # friendly names from live listing work
./htb vpn download us-free-1 -o lab-vpn.ovpn  # download the assigned server
./htb vpn connect us-free-1 -o lab-vpn.ovpn

# Speedrun a seasonal release: connect VPN, set MTU 1300, spawn, wait for IP.
sudo "$(command -v htb)" speedrun Seasonal us-free-1
sudo "$(command -v htb)" speedrun Pov 'US Machines VIP+ 1'

./htb raw GET /machine/active
./htb raw POST /vm/spawn --data '{"machine_id":478}'

Output

By default, commands print human-readable output with terminal-width wrapping and automatic color when stdout is an interactive terminal.

Use raw JSON for scripts:

./htb --json machine active

Color can be controlled globally:

./htb --color never machine active
./htb --color always machine list

Tables are compact by default and truncate long cells to fit common terminal widths. Use --wide to keep full table values:

./htb --wide machine list
./htb --wide machine search active-directory --all

machine active enriches the active session response with the matching machine profile when a machine is active, but prints a compact summary by default. The summary includes useful profile-only text such as info_status and description when HTB returns it. Use --details for synopsis and Academy module names, or --json before the command for the full enriched response:

./htb machine active --details
./htb --json machine active

Machine search

machine search intentionally uses the documented/listed Labs v4 machine list endpoints and filters the results locally. It does not depend on an undocumented search endpoint.

By default it scans playable machines:

./htb machine search linux

Useful options:

• --retired: search retired machines only.
• --all: search playable and retired machines.
• --profiles: also fetch each scanned machine profile and search profile-only fields such as descriptions.
• --limit N: stop after printing up to N matches.
• --max-pages N: cap the number of API pages scanned per list.

Without --profiles, the query matches machine id, name, OS, difficulty, tags, maker names, and common list fields. Use --profiles for terms that may only exist in the detailed machine profile, for example description text mentioning breached credentials.

Spawn a seasonal box with --wait

When a seasonal machine drops (Saturdays 19:00 UTC) the spawn servers are full, so a plain machine start fails immediately with a capacity error. If you are already connected to the VPN, add --wait to keep retrying until a slot frees up and then block until the machine reports its IP:

./htb machine start Connected --mode auto --wait --retry-for 360 --interval 5

• --retry-for SECONDS: total time to keep retrying the spawn (default 600).
• --interval SECONDS: base delay between spawn attempts and ready-state polls; each spawn delay is jittered ±20% so simultaneous clients do not retry in lockstep at the release moment.

Only transient rejections are retried -- capacity messages (full, busy, try again, ...) and 429/5xx responses, including the Release Arena's "Failed to spawn ... Please try again." Real failures (bad token, unknown machine) fail fast instead of spinning for minutes.

If HTB rejects the start with "You already have an active instance", the command inspects what is active and reacts automatically:

• Same machine, already has an IP -- returns it without churning the instance.
• Same machine, no IP (stuck slot) -- terminates the stuck instance and retries.
• Different machine is active -- fails with a clear error naming the blocker.

For the full hands-off flow that also connects the VPN and tunes the MTU, use speedrun below.

Speedrun a season release

When a seasonal machine drops (Saturdays 19:00 UTC), the slow part is the manual dance of connecting the VPN, fixing the tunnel MTU, and spamming spawn until a slot frees up. speedrun does all of it in one command and shows a live status for each step:

sudo "$(command -v htb)" speedrun Seasonal us-free-1
sudo "$(command -v htb)" speedrun Pov 'EU Machines VIP+ 1'

speedrun: Seasonal via us-free-1
  resolve machine 'Seasonal' ... ok
  switch vpn server us-free-1 ... ok
  download ovpn config ... ok
  start openvpn ... ok
  wait for tun0 ... ok (3s)
  set tun0 mtu 1300 ... ok
  spawn machine ... ok (42s)
  wait for machine ip ... ok (18s)
┌─ready ────────────────────┐
│ machine   Seasonal        │
│ ip        10.10.11.50     │
│ tunnel    tun0 (mtu 1300) │
└───────────────────────────┘

It needs root (for OpenVPN and the MTU change), so run it with sudo. The VPN runs in the foreground; press Ctrl-C to disconnect. If Ctrl-C or an HTB API failure interrupts any step after OpenVPN starts, speedrun disconnects and reaps OpenVPN automatically. It also verifies that the OpenVPN process and tunnel interface remain active while retrying the spawn and machine IP. Tunables: --mtu, --interface, --retry-for, --interval, --mode, and --variant.

Running speedrun with sudo

speedrun must run as root because it starts OpenVPN and changes the tunnel MTU. With pipx, resolve the executable as your user before sudo applies its restricted PATH:

command -v openvpn ip
sudo -v
sudo "$(command -v htb)" speedrun Seasonal us-free-1

Run htb init first as your normal user. Under sudo, the client checks the current ./api.token, root's config, then the invoking user's default token via SUDO_USER. For a custom XDG location, pass --token-file explicitly. Avoid a persistent /usr/bin symlink to the user-writable pipx command.

vpn connect is different: run htb vpn connect ... normally. Its default sudo openvpn command elevates only OpenVPN, leaving token and API work unprivileged.

Shell completion

Enable tab-completion for commands and subcommands. The same script works for both the htb and htbx commands.

# bash — add to ~/.bashrc:
eval "$(htb completion bash)"

# zsh — add to ~/.zshrc (before compinit, or save to a file on your $fpath):
eval "$(htb completion zsh)"

Architecture

• htb_terminal/cli.py: thin entry point — dispatch and error rendering.
• htb_terminal/parser.py: argparse definitions, one builder per command group.
• htb_terminal/handlers.py: command handlers (args + client -> result).
• htb_terminal/config.py: loads/saves the token and API URL.
• htb_terminal/http.py: authenticated HTTP client.
• htb_terminal/output.py: human-readable and JSON rendering.
• htb_terminal/ui.py: StepRunner live step status for workflows.
• htb_terminal/netcfg.py: host network/process ops (OpenVPN, interface, MTU).
• htb_terminal/timefmt.py: relative time formatting for display.
• htb_terminal/completion.py: bash/zsh completion scripts from one command map.
• htb_terminal/services/machines.py: MachineService — machine API operations.
• htb_terminal/services/user.py: UserService — current-user profile.
• htb_terminal/services/speedrun.py: SpeedrunService — season-release flow.
• htb_terminal/services/payloads.py: pure helpers that reshape machine-list JSON.
• htb_terminal/services/search.py: local machine search and result ranking.
• htb_terminal/services/spawn.py: transient spawn-failure detection.
• htb_terminal/services/vpn.py: VPN and OVPN operations.

Each module keeps a single responsibility to make future changes easier if HTB changes an endpoint. MachineService only talks to the API; payload reshaping, search ranking, and spawn-error detection are stateless modules it composes, so they are testable in isolation and stay small.

Regenerating screenshots

The images in docs/screenshots/ are produced by scripts/screenshots.py, which renders each command's output to SVG with rich and screenshots it with a headless Chromium — no PTY needed, so it works on CI and remote boxes:

pip install -e ".[screenshots]"
python3 scripts/screenshots.py                 # capture all shots
python3 scripts/screenshots.py vpn-servers speedrun   # capture a subset

Commands that hit the API need a saved token (htb init); the machine active shots need an active machine. The speedrun and machine-start-wait shots use the fixed demos scripts/demo_speedrun.py and scripts/demo_seasonal_start.py, which render a realistic status with no token, root, or network.

Development

Install the dev tools and run the test suite:

pip install -e ".[dev]"
pytest
ruff check .

The tests are also runnable with the standard library alone:

python3 -m unittest discover -s tests -v
