# rustguac — example configuration
#
# All settings are optional and have sensible defaults.
# Copy this file to config.toml and adjust as needed.
#
# Usage:
#   rustguac --config config.toml serve

# ─── Server ───────────────────────────────────────────────────────────────────

# Address and port to listen on.
# Default: "127.0.0.1:8089" (loopback only — safe for development).
# For production behind a reverse proxy, use "127.0.0.1:8089".
# To listen on all interfaces: "0.0.0.0:443" (with TLS) or "0.0.0.0:8089".
listen_addr = "127.0.0.1:8089"

# Address of the guacd daemon (Guacamole protocol server).
# Default: "127.0.0.1:4822"
guacd_addr = "127.0.0.1:4822"

# Directory for session recording files (.guac format).
# Default: "./recordings"
# DEPRECATED: use [recording] section below. Kept for backwards compatibility.
recording_path = "./recordings"

# Directory containing static web files (HTML, JS, CSS).
# Default: "./static"
static_path = "./static"

# Path to the SQLite database (admins, OIDC users, auth sessions).
# Default: "./rustguac.db"
db_path = "./rustguac.db"

# Title shown in the browser tab and page header.
# Default: "rustguac"
site_title = "rustguac"

# ─── Session Timeouts ─────────────────────────────────────────────────────────

# Seconds before a pending session expires (no WebSocket connection yet).
# Default: 60
session_pending_timeout_secs = 60

# Maximum duration for active sessions in seconds.
# Sessions running longer than this are automatically terminated.
# Default: 28800 (8 hours). Set to 0 to disable.
session_max_duration_secs = 28800

# OIDC auth session TTL in seconds. After this period, users must
# re-authenticate via their identity provider.
# Default: 86400 (24 hours)
# auth_session_ttl_secs = 86400

# ─── Session Limits ──────────────────────────────────────────────────────────

# Maximum concurrent sessions (all types). Default: 500. Set to 0 for unlimited.
# max_sessions = 500

# Maximum concurrent sessions per user. Default: 50. Set to 0 for unlimited.
# max_sessions_per_user = 50

# Seconds to keep completed sessions in memory before cleanup.
# Session history in SQLite is not affected. Default: 300 (5 minutes).
# session_cleanup_delay_secs = 300

# ─── Browser Sessions (Xvnc + Chromium) ──────────────────────────────────────

# Path to the Xvnc binary (from tigervnc-standalone-server).
# Default: "Xvnc"
xvnc_path = "Xvnc"

# Path to the Chromium binary.
# Default: "chromium"
chromium_path = "chromium"

# X display number range for Xvnc instances.
# Each web browser session gets its own display (:100 = port 6100, etc.).
# Default: 100–199 (up to 100 concurrent web sessions).
display_range_start = 100
display_range_end = 199

# ─── Connection Allowlists (CIDR) ────────────────────────────────────────────
#
# Control which hosts sessions can connect to. Each is a list of CIDR ranges.
# Hostnames are resolved and checked against the allowlist.
# Default for all three: ["127.0.0.0/8", "::1/128"] (localhost only).

# SSH session targets
ssh_allowed_networks = ["127.0.0.0/8", "::1/128", "10.0.0.0/8", "192.168.0.0/16"]

# RDP session targets
rdp_allowed_networks = ["127.0.0.0/8", "::1/128", "10.0.0.0/8", "192.168.0.0/16"]

# Web browser session URL hosts
# Use ["0.0.0.0/0", "::/0"] to allow any host.
web_allowed_networks = ["127.0.0.0/8", "::1/128"]

# ─── Trusted Proxies ────────────────────────────────────────────────────────
#
# CIDRs of reverse proxies whose X-Forwarded-For header should be trusted.
# When a connection comes from a trusted proxy, the first IP in
# X-Forwarded-For is used as the client IP in audit logs and rate limiting.
# Default: [] (empty — always use socket address)

# trusted_proxies = ["127.0.0.0/8", "::1/128"]

# ─── TLS ──────────────────────────────────────────────────────────────────────
#
# Enables HTTPS for clients and optionally TLS for the guacd connection.
# Omit the entire [tls] section to run plain HTTP (for development or
# when behind a TLS-terminating reverse proxy).
#
# Generate a self-signed cert:
#   rustguac generate-cert --hostname your-hostname.example.com --out-dir ./tls

# [tls]
# # HTTPS certificate and private key
# cert_path = "/opt/rustguac/tls/cert.pem"
# key_path = "/opt/rustguac/tls/key.pem"
#
# # Trust this certificate for the guacd TLS connection (optional).
# # When set, rustguac connects to guacd over TLS.
# # The same self-signed cert can serve both purposes.
# # Omit for plain TCP to guacd.
# guacd_cert_path = "/opt/rustguac/tls/cert.pem"

# ─── OIDC (Single Sign-On) ───────────────────────────────────────────────────
#
# Enables OpenID Connect authentication. Works with any OIDC provider:
# Authentik, Keycloak, Okta, Azure AD, Google, etc.
#
# The client_secret can also be set via the OIDC_CLIENT_SECRET environment
# variable, which takes precedence over this config file. Recommended for
# production (Docker secrets, systemd EnvironmentFile, etc.).
#
# When OIDC is configured, the web UI shows a login button. API key auth
# continues to work alongside OIDC.

# [oidc]
# issuer_url = "https://authentik.example.com/application/o/rustguac/"
# client_id = "your-client-id"
# client_secret = "your-client-secret"   # or set OIDC_CLIENT_SECRET env var
# redirect_uri = "https://your-host/auth/callback"
#
# # Role assigned to new users on first login.
# # Options: "admin", "poweruser", "operator", "viewer"
# # Default: "operator"
# default_role = "operator"
#
# # OIDC claim name containing group memberships (default: "groups").
# groups_claim = "groups"
#
# # Extra OIDC scopes to request beyond openid/email/profile.
# extra_scopes = ["groups"]
#
# # Custom CA certificate (PEM) for verifying the OIDC provider.
# # Use this when your IdP uses a private or internal CA not in the system trust store.
# # ca_cert = "/etc/ssl/private/internal-ca.pem"
#
# # Skip TLS certificate verification for OIDC connections (default: false).
# # WARNING: Only use for debugging — exposes client_secret and tokens to MITM attacks.
# # tls_skip_verify = false

# ─── Vault / Address Book ──────────────────────────────────────────────────
#
# Enables the Vault-backed address book. Connection entries (SSH, RDP, Web)
# are stored in HashiVault or OpenBao KV v2. Credentials never reach the
# browser — the server reads them from Vault and creates sessions directly.
#
# Authentication uses AppRole. The secret_id is provided via the
# VAULT_SECRET_ID environment variable.
#
# Vault KV v2 path structure:
#   <base_path>/shared/<folder>/<entry>          — shared across instances
#   <base_path>/instance/<name>/<folder>/<entry>  — instance-specific
#   <folder>/.config — folder metadata (allowed_groups, description)

# [vault]
# addr = "https://vault.example.com:8200"
# mount = "secret"            # KV v2 mount (default: "secret")
# base_path = "rustguac"      # base path under mount (default: "rustguac")
# role_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
# # namespace = "my-ns"       # optional, Vault Enterprise / OpenBao namespaces
# # instance_name = "prod-1"  # optional, enables instance-scoped entries
# # tls_skip_verify = false   # skip TLS cert verification (dev only, default: false)

# ─── Recording ──────────────────────────────────────────────────────────────
#
# Controls session recording and automatic rotation.
# If omitted, recordings are enabled with no automatic cleanup.
# The path can also be set via the top-level recording_path key
# (the [recording] section takes precedence).

# [recording]
# path = "./recordings"              # recording directory (default: "./recordings")
# enabled = true                     # master switch (default: true)
# max_disk_percent = 80              # delete oldest when disk usage exceeds % (0 = disable)
# max_recordings = 0                 # global max recording count (0 = unlimited)
# rotation_interval_secs = 300       # how often to check rotation (seconds, default: 300)

# ─── Theme ────────────────────────────────────────────────────────────────────
#
# Customize the web UI appearance. Pick a built-in preset and optionally
# override individual colors. Users can switch themes in the browser via
# the theme switcher (persisted in localStorage).
#
# Built-in presets: aurora (default), dark, light, high-contrast, terminal,
# nord, corporate, jaguar
#
# All color values are CSS color strings (hex, rgb(), hsl(), named colors).

# [theme]
# preset = "aurora"                 # built-in preset to use as the base
# logo_url = "/logo.svg"            # custom logo URL (shown on login + nav)
#
# # Override individual colors on top of the preset:
# # primary_color = "#e94560"
# # accent_color = "#5bc0be"
# # bg_color = "#1a1a2e"
# # surface_color = "#16213e"
# # text_color = "#e0e0e0"
# # text_muted = "#aaa"
# # border_color = "#333"
# # input_color = "#0f3460"
# # primary_hover = "#c73652"
# # accent_hover = "#4aa3a1"
# # text_dim = "#888"
# # text_on_primary = "#fff"
# # btn_disabled = "#555"
# # status_pending = "#f0c040"
# # status_active = "#5bc0be"
# # status_completed = "#888"
# # status_error = "#e94560"
# # status_expired = "#666"

# ─── Drive / File Transfer ──────────────────────────────────────────────────
#
# Enables file transfer for RDP (drive redirection) and SSH (SFTP) sessions.
#
# RDP: A per-session directory under drive_path is mounted as a virtual drive
#      visible in the remote Windows session (e.g. "Shared Drive" in Explorer).
# SSH: SFTP file transfer directly between browser and target SSH server.
#      No files stored on the rustguac server for SSH sessions.
#
# SECURITY: For RDP drive storage, use the LUKS options below to encrypt the
# drive_path volume. The encryption key is stored in Vault and the volume is
# only unlocked while rustguac is running.

# [drive]
# enabled = true
# drive_path = "/mnt/rustguac-drives"   # mount point / base dir for per-session storage
# drive_name = "Shared Drive"           # name shown in remote RDP session
# allow_download = true                 # allow downloading files from remote
# allow_upload = true                   # allow uploading files to remote
# cleanup_on_close = true               # delete session drive dir on session end
# retention_secs = 0                    # delay before cleanup (0 = immediate)
#
# # LUKS encryption (optional, requires Vault)
# # The install script can set this up interactively.
# luks_device = "/opt/rustguac/drives.luks"    # LUKS container file
# luks_name = "rustguac-drives"                # device-mapper name
# luks_key_path = "rustguac/luks-key"          # Vault KV path for encryption key

# ──────────────────────────────────────────────────────────────────
# RDP defaults
# ──────────────────────────────────────────────────────────────────
#
# Applied to every RDP session unless the address book entry (or the
# ad-hoc connect request) overrides the same field.
#
# default_auth_pkg: NLA/CredSSP authentication package. Rustguac
# defaults to "ntlm" because Kerberos requires a KDC reachable via
# DNS (usually over TCP) and its failure mode is a silent hang.
# Set to "kerberos" if you actually run AD-integrated hosts with
# Kerberos working. "negotiate" means Kerberos-first with NTLM
# fallback and is also prone to the silent-hang failure mode.
# Leave commented to accept the "ntlm" default.

# [rdp]
# default_auth_pkg = "ntlm"
