+## Docker Deployment
+
+Rustsploit ships with a standalone provisioning script that builds and launches the API inside Docker (mirroring the multi-stage workflow used in vxcontrol/pentagi).
+
+### Requirements
+
+- Docker Engine 24+ (or Docker Desktop)
+- Docker Compose plugin (`docker compose`) or legacy `docker-compose`
+- Python 3.8+
+
+### Interactive Setup
+
+```bash
+python3 scripts/setup_docker.py
+```
+
+The helper will:
+
+1. Confirm you are in the repository root (`Cargo.toml` present).
+2. Ask how the API should bind (`127.0.0.1`, `0.0.0.0`, detected LAN IP, or custom host:port).
+3. Let you enter or auto-generate an API key (printable ASCII, 128 chars max).
+4. Toggle hardening mode and tune the IP limit if desired.
+5. Generate:
+   - `docker/Dockerfile.api` (build + serve stages)
+   - `docker/entrypoint.sh` (passes CLI flags / hardening state)
+   - `.env.rustsploit-docker` (API key, bind address, hardening settings)
+   - `docker-compose.rustsploit.yml`
+6. Optionally run `docker compose up -d --build` with BuildKit enabled.
+
+Existing files are never overwritten without confirmation (use `--force` for scripted deployments).
+
+### Non-Interactive / CI Usage
+
+All prompts have CLI equivalents:
+
+```bash
+python3 scripts/setup_docker.py \
+  --bind 0.0.0.0:8443 \
+  --generate-key \
+  --enable-hardening \
+  --ip-limit 5 \
+  --skip-up \
+  --force \
+  --non-interactive
+```
+
+This produces the Docker assets but skips the compose launch. To start the stack later:
+
+```bash
+docker compose -f docker-compose.rustsploit.yml up -d --build
+```
+
+Environment variables are written with 0600 permissions so secrets stay private. Re-run the script any time you want to regenerate artefacts or rotate the API key.

+## API Server Mode
+
+Rustsploit includes a REST API server mode that allows remote control of the tool via HTTP endpoints. The API includes authentication, rate limiting, IP tracking, and security hardening features.
+
+### Starting the API Server
+
+```bash
+# Basic API server (defaults to 0.0.0.0:8080)
+cargo run -- --api --api-key your-secret-key-here
+
+# With hardening enabled (auto-rotate API key on suspicious activity)
+cargo run -- --api --api-key your-secret-key-here --harden
+
+# Custom interface and IP limit
+cargo run -- --api --api-key your-secret-key-here --harden --interface 127.0.0.1 --ip-limit 5
+
+# Custom port
+cargo run -- --api --api-key your-secret-key-here --interface 0.0.0.0:9000
+```
+
+### API Flags
+
+| Flag | Description | Required |
+|------|-------------|----------|
+| `--api` | Enable API server mode | Yes |
+| `--api-key <key>` | API key for authentication | Yes (when using `--api`) |
+| `--harden` | Enable hardening mode (auto-rotate key on suspicious activity) | No |
+| `--interface <addr>` | Network interface/IP to bind to (default: `0.0.0.0`) | No |
+| `--ip-limit <num>` | Maximum unique IPs before auto-rotation (default: 10, requires `--harden`) | No |
+
+### API Endpoints
+
+All endpoints except `/health` require authentication via the `Authorization` header:
+
+```bash
+# Bearer token format
+Authorization: Bearer your-api-key-here
+
+# Or ApiKey format
+Authorization: ApiKey your-api-key-here
+```
+
+#### Public Endpoints
+
+- **`GET /health`** - Health check (no authentication required)
+  ```bash
+  curl http://localhost:8080/health
+  ```
+
+#### Protected Endpoints
+
+- **`GET /api/modules`** - List all available modules
+  ```bash
+  curl -H "Authorization: Bearer your-api-key" http://localhost:8080/api/modules
+  ```
+
+- **`POST /api/run`** - Execute a module on a target
+  ```bash
+  curl -X POST -H "Authorization: Bearer your-api-key" \
+       -H "Content-Type: application/json" \
+       -d '{"module": "scanners/port_scanner", "target": "192.168.1.1"}' \
+       http://localhost:8080/api/run
+  ```
+
+- **`GET /api/status`** - Get API server status and statistics
+  ```bash
+  curl -H "Authorization: Bearer your-api-key" http://localhost:8080/api/status
+  ```
+
+- **`POST /api/rotate-key`** - Manually rotate the API key
+  ```bash
+  curl -X POST -H "Authorization: Bearer your-api-key" \
+       http://localhost:8080/api/rotate-key
+  ```
+
+- **`GET /api/ips`** - Get all tracked IP addresses with details
+  ```bash
+  curl -H "Authorization: Bearer your-api-key" http://localhost:8080/api/ips
+  ```
+
+- **`GET /api/auth-failures`** - Get authentication failure statistics
+  ```bash
+  curl -H "Authorization: Bearer your-api-key" http://localhost:8080/api/auth-failures
+  ```
+
+### Security Features
+
+#### Rate Limiting
+- IPs are automatically blocked for **30 seconds** after **3 failed authentication attempts**
+- Blocked IPs receive HTTP `429 Too Many Requests` responses
+- Failed attempts are logged to both terminal and log file
+- Counter resets automatically after the block period expires
+- Successful authentication resets the failure counter for that IP
+
+#### Hardening Mode
+When `--harden` is enabled:
+- Tracks unique IP addresses accessing the API
+- Automatically rotates the API key when the number of unique IPs exceeds the limit (default: 10)
+- Logs all rotation events to terminal and `rustsploit_api.log`
+- Clears IP tracking after key rotation
+
+#### Logging
+All API activity is logged to:
+- **Terminal:** Real-time console output with colored status messages
+- **Log File:** `rustsploit_api.log` in the current working directory
+
+Log entries include:
+- API requests and responses
+- Authentication failures and rate limiting events
+- IP tracking and hardening actions
+- Key rotation events
+- Module execution results
+
+### Example API Workflow
+
+```bash
+# 1. Start the API server
+cargo run -- --api --api-key my-secret-key --harden --ip-limit 5
+
+# 2. Check health
+curl http://localhost:8080/health
+
+# 3. List available modules
+curl -H "Authorization: Bearer my-secret-key" http://localhost:8080/api/modules
+
+# 4. Run a port scan
+curl -X POST -H "Authorization: Bearer my-secret-key" \
+     -H "Content-Type: application/json" \
+     -d '{"module": "scanners/port_scanner", "target": "192.168.1.1"}' \
+     http://localhost:8080/api/run
+
+# 5. Check status
+curl -H "Authorization: Bearer my-secret-key" http://localhost:8080/api/status
+
+# 6. View tracked IPs
+curl -H "Authorization: Bearer my-secret-key" http://localhost:8080/api/ips

+
+Improved the telnet bruteforce module with safer inputs and sturdier execution:
+
+Added guarded prompts for port, thread count, yes/no answers, and wordlist paths (loops until valid input, checks file existence). Blank or invalid inputs now fall back to sensible defaults or re-prompt instead of panicking.
+Wordlists are trimmed and filtered, with explicit errors when the files are empty—preventing silent no-op bruteforcing.
+Swapped the shared stop flag to an AtomicBool so workers react immediately when a credential is found while stop_on_success is enabled.
+Counted queued combinations up front and log the total attempts for visibility.
+
+
+Added a powerful raw brute-force option to the Telnet module:
+Prompts now support programmatic password generation: answer “yes” to “Enable raw brute-force password generation?” to supply a character set (default a-zA-Z0-9) and a maximum length (bounded to 1–6).
+Wordlists became optional when raw mode is on (leave the password wordlist blank to skip it); the module still accepts wordlists and can combine them with raw guesses.
+Queue building now streams through a background generator thread that respects the shared stop_on_success flag (AtomicBool) and counts attempts via an AtomicUsize.
+Improved input validation for ports, thread counts, yes/no answers, and file paths; empty lists now raise clear errors.
+Logged attempt counts and status messages highlight usernames/passwords loaded and total credentials queued.
+
+
+
+Credential Modules
+Hardened the SSH brute-force runner with validated host normalization, atomic stop control, and a bounded async work queue so we no longer pile up tasks or contend on a mutex; workers now exit immediately once a hit is found while still honoring combo mode and verbose logging.
+
+FTP Bruteforce Fixes
+Swapped the shared stop flag to an Arc<AtomicBool> and tightened the worker loops so we stop queuing attempts immediately after a hit while still letting outstanding tasks exit cleanly under the semaphore cap.
+
+Simplified throttling: we dropped the expensive system-polling loop and now rely on the semaphore for connection pressure, plus clearer panic logging in the join loop.
+Extended try_ftp_login with a verbose toggle so noisy connection failures only print when requested, while still surfacing TLS fallbacks or critical errors.
+
+Replaced the brute-force loop with a semaphore-guarded task queue so concurrency stays bounded, tasks bail fast once a hit is found, and DNS results are resolved once and reused across attempts.
+
+Added shared header storage plus richer error messages that identify the target when RTSP replies are unexpected or connections fail.
+
+Advanced headers are now shared via Arc, and the stop flag moved to AtomicBool so threads don’t block on a mutex when cancelling runs.
+
+RTSP Target Support Updates
+Added centralized target normalization so the module now accepts domains, IPv4, IPv6 (with or without brackets), optional schemes, and inline RTSP paths; inferred paths are queued first in the brute-force list.
+
+Introduced normalize_target_input to standardize host/port handling and trim any implicit path/query fragments before resolution.
+
+No automated tests were run; consider a quick RTSP smoke test against known IPv4/IPv6 endpoints to confirm resolution and path detection behave as expected.
+
+Introduced shared prompt utilities for ports, thread counts, yes/no answers, and wordlists so SMTP input handling now mirrors the other modules and gives consistent feedback on bad values.
+
+Reworked the SMTP brute-force module to match our richer prompt UX and concurrency story: inputs are validated, wordlists must exist, and worker threads respect an AtomicBool stop flag while reporting loaded counts and draining the queue on success.
+
+Added reusable helpers for SSH input validation—targets are normalized through DNS-safe bracket handling and wordlists must exist before continuing—so mis-typed hosts or files fail fast with actionable feedback.
+
+Hardened the REPL inputs: we now cap command length, sanitize module paths, and refuse targets with whitespace/control chars so only vetted values reach the module runner and env vars.
+
+Locked down proxy usage by deduplicating/truncating large lists before activation, making it harder to feed an unbounded or repeated proxy set into env vars.
+
+Added explicit sanitizers for module paths/targets to block traversal attempts and exotic characters before they ever touch utils::module_exists or shared state.
+
+Docker Setup Utility
+
+Added scripts/setup_docker.py, a standalone interactive helper that:
+Detects repo root, validates Docker/Docker Compose availability, and guides users through binding address selection (loopback, 0.0.0.0, detected LAN IP, or custom).
+Prompts for API key (custom or securely generated), optional hardening toggle, and IP-limit.
+Generates a multi-stage Dockerfile (docker/Dockerfile.api) matching the requested build/serve stages, a hardened entrypoint (docker/entrypoint.sh), a project-specific compose file (docker-compose.rustsploit.yml), and an environment file (.env.rustsploit-docker).
+Optionally runs docker compose up -d --build to bring the API online with the chosen configuration.
+
+Usage
+
+From the repo root, run python3 scripts/setup_docker.py.
+Follow the prompts to select interface, API key, and hardening settings.
+Allow the script to generate files and (optionally) launch the Docker stack.
+If you skip the final step, start the stack later with:
+docker compose -f docker-compose.rustsploit.yml up -d --build
+All new files are created only after confirmation when existing content is detected, preventing accidental overwrites.
+
+Rebuilt scripts/setup_docker.py into a safer CLI/interactive hybrid:
+Validates repo root, docker/docker‑compose availability, and enforces printable API keys with optional random generation.
+Adds flags (--bind, --port, --api-key, --generate-key, --enable-hardening, --disable-hardening, --ip-limit, --compose-cmd, --skip-up, --force, --non-interactive) so the tool can be scripted or used interactively.
+Normalizes host/port selection (loopback, all interfaces, detected LAN, or custom) and applies strict parsing for non-interactive use.
+Generates Dockerfile, entrypoint, Compose file, and env file with restricted permissions (.env written 0600), docker security options (no-new-privileges, tmpfs /tmp), and port bindings derived from user choices.
+Supports BuildKit-enabled docker compose up -d --build, or skips launch when --skip-up is set.
+
+Reworked run to drive a multi-target workflow: it now gathers sanitized targets from CLI, interactive prompts, or files, applies per-target ports (including ip:port forms), and iterates through them while reusing a single DNS query configuration.
+
+Added robust parsing, validation, and de-duplication helpers for targets, with stop handling, file support, and strict host/port sanitization so mixed IPs/domains and custom ports are accepted safely.

+Diagnosis
+
+The compiler couldn't prove the loop would exit because:
+The break only exited the inner for loop, not the outer loop.
+Even with a flag, the compiler couldn't track that it would be set inside nested match/for structures.
+The code after the loop was considered unreachable.
+
+Solution
+Used a labeled break:
+Added a label 'main_loop: to the outer loop (line 39).
+Changed the exit command to use break 'main_loop; (line 78), which breaks directly out of the labeled loop.
+This makes the exit path explicit and provable, so the code after the loop is reachable.
+Control flow now:
+Main loop starts with label 'main_loop.
+User enters commands (can be chained with &).
+When "exit" is entered, break 'main_loop; exits the outer loop directly.
+Execution reaches Ok(()) after the loop.
+This is the idiomatic Rust approach for breaking out of nested loops and resolves the unreachable code warning. The code should compile without warnings.
+add back command with shortcuts
+
+Adding a "back" command with shortcuts. Checking the current command structure:
+Adding a "back" command with shortcuts to clear the current module and target:
+
+
+Changes Made:
+
+Added the "back" command handler (lines 80-84):
+Clears the current module selection
+Clears the current target
+Shows a confirmation message
+Added shortcuts in resolve_command (line 353):
+back - full command
+b - short shortcut
+clear - alternative name
+reset - alternative name
+Added to help menu (line 416):
+Listed with its shortcuts and description
+Usage:
+You can now use any of these to clear the current module and target:
+
+
+All compilation errors are fixed. Summary of changes:
+SNMP packet encoding: Rewrote to use proper BER TLV (Type-Length-Value) encoding
+Error handling: EAGAIN/EWOULDBLOCK errors are treated as timeouts (invalid community strings)
+Type inference: Fixed async function return types
+The module should compile and run. The SNMP packet encoding now follows the BER format, and socket errors are handled correctly.
+
+Try running it again. The module should:
+
+Build SNMP GET requests correctly
+Handle timeouts and socket errors gracefully
+Detect valid community strings when SNMP responses are received
+If you encounter any runtime issues, share the details and I can help debug.
+it should ask for username and passoword and add error handling input validaitpon and all porper safetys. also can you add a new feature where i can combine multaible commands to execute in a row like use module & set target & run in this format it should work usable in modules 2 without chanign modules.

+
+Summary
+1. Improved SNMP module input validation
+Port validation: checks range 1-65535 with clear error messages
+File validation: verifies file exists, is a regular file, and is readable before proceeding
+Concurrency validation: limits 1-10000 with clear error messages
+Timeout validation: limits 1-300 seconds with clear error messages
+All prompts include error handling and retry loops
+2. Command chaining support
+Added support for chaining commands with & separator
+Example: use creds/generic/snmp_bruteforce & set target 192.168.1.1 & run
+Commands execute sequentially in the same context
+Works across all modules without changing module context
+The exit command properly exits even when chained
+
+
+Usage Examples:
+# Chain multiple commandsrsf> use creds/generic/snmp_bruteforce & set target 192.168.1.1 & run# Works with any commandsrsf> use exploits/some_exploit & set target 10.0.0.1 & run# Can chain any commandsrsf> modules & find snmp & use creds/generic/snmp_bruteforce
+
+The SNMP module now has:
+Better input validation with clear error messages
+File existence and readability checks
+Range validation for all numeric inputs
+Proper error handling throughout
+
+
+RDP Bruteforce Module Improvements
+1. Improved concurrency handling
+Switched from Vec<JoinHandle> to FuturesUnordered for better task management

+More efficient task scheduling and completion handling
+2. Better stop signal management
+Replaced Mutex<bool> with AtomicBool for the stop signal
+Lock-free, more efficient for frequent reads
+Uses Ordering::Relaxed for performance
+3. Enhanced timeout handling

+Uses tokio::time::timeout to enforce timeouts
+Kills hung processes on timeout
+4. Input validation
+Validates file paths before use
+Checks file existence and readability
+Clear error messages for invalid inputs

+### L2TP/IPsec VPN Bruteforce Module
+
+Created an L2TP/IPsec VPN bruteforce module. Summary:
+Features implemented
+L2TP/IPsec authentication support
+
+Two-phase authentication:
+
+IPsec phase: machine authentication with optional PSK (pre-shared key)
+L2TP phase: user authentication with username/password
+Supports multiple L2TP client tools:
+strongswan (ipsec)
+xl2tpd
+
+pppd with L2TP plugin (Linux)
+Configuration options
+Configurable port (default: 500 for IKE)
+Optional PSK for IPsec authentication
+Username/password wordlists
+IPv4/IPv6 support with proper address normalization
+Bruteforce capabilities
+Combination mode (every password with every user)
+Sequential mode (cycling through users)
+Configurable concurrency
+Timeout handling
+Stop on first success option
+Framework structure
+Follows the same patterns as other bruteforce modules
+Proper error handling
+Results saving to file
+Verbose mode support
+Implementation notes
+L2TP/IPsec authentication is complex and requires:
+Root privileges for IPsec operations
+System configuration files (/etc/ipsec.conf, /etc/ipsec.secrets, etc.)
+Proper IPsec tunnel establishment before L2TP authentication
+
+The current implementation provides:
+
+Framework and structure for L2TP bruteforcing
+Detection of available L2TP client tools
+Basic connection testing
+Full parameter support (IPs, ports, usernames, passwords, PSK)
+For a production implementation, you would need to:
+Create temporary configuration files dynamically
+Use proper ipsec commands to establish IPsec tunnels
+Use xl2tpd or pppd commands to establish L2TP tunnels
+Parse connection status and authentication responses
+The module is registered in mod.rs and ready to use. It will automatically be picked up by the build system.
+wire everything toghter and make it fully working with the framework
+
+Verifying the L2TP bruteforce module is integrated with the framework and fully functional. Checking integration points and fixing any issues.
+Improving the L2TP implementation to be more functional and ensuring it integrates with the framework. Enhancing the connection logic:

+Resource cleanup and bounds checking
+
+
+
+Key Bug Fixes:
+
+Fixed receiver cloning issue - The main bug. Workers now use Arc<Mutex<Receiver>> to properly share the channel receiver
+Fixed raw password generation - The odometer logic now uses proper carry detection to avoid infinite loops and correctly exhaust all combinations
+Made save_results async - Converted to async to match the rest of the codebase
+Removed unused functions - Cleaned up save_results_blocking and prompt_threads_default duplicates
+
+
+ Safety Improvements:
+
+    Command Chain Limit: Added MAX_COMMAND_CHAIN_LENGTH constant to prevent DoS via excessive command chaining
+    Fixed unwrap() panics:
+        In pick_random_untried_proxy(): Changed .unwrap() to proper fallback handling
+        Added null checks before unwrapping
+    Proper error handling: All prompt functions now have their errors properly handled instead of using ? which could crash the shell
+    Target sanitization relaxed: Removed whitespace restriction (targets can be URLs with spaces in query params), kept control character blocking for security
+    Module path sanitization: Added - to allowed characters (common in module names)
+    Validation on prompt_u64: Added check to ensure value is greater than 0
+    Safer proxy selection: Added fallback logic in case the proxy list becomes empty during selection
+    Memory safety: All existing size limits maintained (MAX_INPUT_LENGTH, MAX_PROXY_LIST_SIZE, MAX_TARGET_LENGTH)
+
+API Key Validation: Added check to ensure API key is not empty/whitespace-only
+Bind Address Validation: Created parse_and_validate_bind_address() function that:
+
+Properly parses IP addresses using std::net::IpAddr
+Validates socket addresses using std::net::SocketAddr
+Prevents binding to port 0
+Rejects invalid IP addresses (like "256.0.0.1")
+Rejects malformed addresses
+Provides clear error messages
+
+
+IP Limit Validation:
+
+Ensures ip_limit is greater than 0
+Adds upper bound check (max 10000) to prevent resource exhaustion
+
+
+Better Error Messages: All validation errors now include descriptive context about what went wrong and expected formats
+
+Fixed unwrap() bug in try_rdp_login: Changed from .unwrap() to proper conditional checking to avoid panics when checking if xfreerdp/rdesktop is available
+Line-by-line reading for combo mode: Instead of loading all passwords into memory, the code now reads the password file line-by-line for each user, greatly reducing memory usage for large wordlists
+Line-by-line reading for sequential mode: Password file is now read line-by-line using .enumerate() to track position for cycling through users
+Added count_lines() function: Efficiently counts lines without loading them into memory, used for displaying wordlist sizes
+Improved error handling: Better handling of file read errors with proper Result checks instead of relying on unwrap()
+Fixed task limiting: Properly drains tasks during iteration to prevent unbounded task accumulation
