**VPN Up** is a secure, scriptable command-line VPN manager for [OpenConnect](https://www.infradead.org/openconnect/). It connects macOS and Linux machines to **Cisco AnyConnect**, Palo Alto **GlobalProtect**, **Pulse Secure**, **Juniper Network Connect**, and **ocserv** gateways straight from the terminal — with named profiles, simultaneous tunnels, Duo 2FA, certificate pinning, secure secret storage, auto-reconnect, and shell completion.

It's built for developers, consultants, DevOps engineers, and remote workers who'd rather drive their VPN from the command line than a vendor GUI.

## ❓ Why use VPN Up?

- Connect to Cisco AnyConnect-compatible VPNs without the official GUI client
- Manage multiple OpenConnect VPN profiles, connect by name, and run compatible profiles side by side (`vpn-up start "Work VPN"`)
- Use **Duo 2FA** from the command line — push, phone, SMS, or one-time passcode
- Store VPN secrets in the macOS **Keychain**, Linux **Secret Service**, or an encrypted OpenSSL vault — never in plaintext config files
- Run VPN connections as **launchd/systemd login services** with auto-reconnect
- Script VPN startup into your development, automation, and remote-support workflows

## 👤 Who is this for?

VPN Up is useful if you:

- Use OpenConnect instead of vendor VPN clients
- Connect to Cisco AnyConnect, GlobalProtect, Pulse Secure, Juniper, or ocserv VPNs
- Want a terminal-first VPN workflow on macOS or Linux
- Juggle multiple client VPN profiles on one machine, including simultaneous tunnels when their routes can coexist
- Need Duo 2FA support from the command line
- Want secure password storage without plaintext config files
- Want VPN auto-reconnect at login via launchd or systemd

## 🌟 Key Features

### Connect
- **Four SSL VPN protocols** via [OpenConnect](https://www.infradead.org/openconnect/): Cisco **AnyConnect** (and ocserv), Juniper **Network Connect**, Palo Alto **GlobalProtect**, and **Pulse Secure**
- **Multiple VPN profiles and tunnels** — pick from an interactive menu or connect by name with zero prompts (`vpn-up start "Work VPN"`), with full **AuthGroup/realm** support; compatible profiles can stay connected at the same time
- **Duo 2FA** — `push`, `phone`, `sms`, or one-time passcodes prompted at connect time; empty method lets the gateway auto-push
- **TOTP authenticator-app 2FA** — store the seed once and `vpn-up` generates the code at connect time (via `oathtool`); fully non-interactive, so it works as an auto-reconnecting login service
- **SSO / external-browser login** — for gateways that force a browser-based SAML/SSO flow (Okta, Azure AD, Ping Identity, often with an embedded Duo iframe), via OpenConnect's `--external-browser` (needs openconnect ≥ 9.0). Because the login runs in your **real** browser, **passkeys / FIDO2 / YubiKey-WebAuthn work automatically**
- **Client-certificate authentication** — an X.509 cert/key file *or* a **PKCS#11** smartcard / **YubiKey PIV**, on its own or alongside a password/SSO; the key passphrase or PIN is kept out of the process table
- **Background or foreground** execution, per your config

### Secure
- **No plaintext passwords** — secrets live in the macOS **Keychain**, Linux **Secret Service**, or an AES-256-CBC + PBKDF2 OpenSSL vault; legacy plaintext is migrated and scrubbed automatically, and secrets never appear on command lines or in child-process environments
- **Fail-closed server identity** — `pin-sha256` certificate pinning with a one-command pin fetch, or strict system trust-store validation
- **The sudo password is never stored** — interactive prompt by default, or a sudoers rule scoped to the one `openconnect` binary
- **Isolated user data** — config, profiles, secrets, and logs live in `~/.config/vpn-up` with `600`/`700` permissions, untouched by updates or reinstalls

### Operate
- **Profile-aware lifecycle** — `status` shows every running tunnel with profile, gateway, and uptime; `stop` and `logs -f` target a specific connection
- **Login service with auto-reconnect** — launchd (macOS) / systemd (Linux) supervision; reconnects when the tunnel drops
- **Lifecycle hooks** — run your own scripts on connect/disconnect (mount shares, switch proxies)
- **Desktop notifications** on connect/disconnect (Notification Center / `notify-send`)

### Manage
- **Guided setup** — a first-run wizard plus `add-profile` / `remove-profile`, which handle XML, secrets, pins, and services in one step
- **`doctor`** diagnostics — environment, dependencies, secret backend, and config at a glance
- **Bash/zsh tab completion** for commands and profile names
- **Hardened & tested** — 100+ tests on macOS + Ubuntu in CI, shellcheck-clean, secret scanning, modern Bash (≥ 4), no `eval`

## ⚖️ VPN Up vs. raw OpenConnect

VPN Up is not a replacement for OpenConnect — it's a safer, more convenient wrapper around it for people who want profile management, secure secrets, 2FA prompts, certificate pinning, logs, completion, and service management instead of long ad-hoc command lines.

| Feature | Raw `openconnect` | VPN Up |
|---|:---:|:---:|
| Multiple named profiles | manual | ✅ |
| Secure secret storage (Keychain/keyring/vault) | — | ✅ |
| Duo 2FA prompts (push/phone/sms/passcode) | manual | ✅ |
| Certificate-pinning helper | manual | ✅ |
| Auto-reconnect login service (launchd/systemd) | manual | ✅ |
| Profile-aware `status` / `logs` / `stop` | — | ✅ |
| Shell completion | — | ✅ |
| Connect/disconnect hooks & notifications | — | ✅ |

It works as a command-line alternative to vendor clients such as the Cisco AnyConnect Secure Mobility Client, GlobalProtect, Pulse Secure, or Juniper Network Connect whenever your gateway speaks an OpenConnect-compatible protocol.

---

## 💡 Common use cases

- Connect to a Cisco AnyConnect VPN from the macOS or Linux terminal
- Use OpenConnect with Duo Push authentication
- Manage multiple client VPN profiles on one machine
- Start a VPN automatically at login on macOS (launchd) or Linux (systemd)
- Run OpenConnect with certificate pinning for a known gateway
- Store VPN credentials securely outside plaintext files
- Script VPN startup before running developer tools or remote-support tasks

---

## 📋 Prerequisites & Installation

### Homebrew (macOS / Linux — recommended)

```bash
brew tap sorinipate/vpn-up
brew install vpn-up
```

Installs the `vpn-up` command with all dependencies (modern Bash, openconnect, xmlstarlet) and bash completion. Your data stays in `~/.config/vpn-up` either way.

### Manual — macOS (Apple Silicon / Intel)

macOS ships with Bash 3.2. Install modern Bash and the dependencies:

```bash
brew install bash openconnect xmlstarlet
```

Ensure Homebrew Bash is first in your PATH:

```bash
echo 'export PATH="/opt/homebrew/bin:$PATH"' >> ~/.zprofile
exec $SHELL -l
```

Then clone and run:

```bash
git clone https://github.com/sorinipate/vpn-up-for-openconnect.git
cd vpn-up-for-openconnect
chmod +x vpn-up.command
```

### Manual — Linux

```bash
# Debian / Ubuntu
sudo apt install bash openconnect xmlstarlet openssl

# RHEL / CentOS
sudo yum install bash openconnect xmlstarlet openssl

# Fedora
sudo dnf install bash openconnect xmlstarlet openssl
```

Optional (recommended): `secret-tool` for Secret Service keyring storage.

---

## 🚀 Quick Start

```bash
vpn-up setup          # one-time configuration wizard
vpn-up add-profile    # guided profile creation (+ password, + certificate pin)
vpn-up start          # connect (interactive menu)
```

> Manual installs: use `./vpn-up.command` instead of `vpn-up` throughout.

---

## ▶️ Usage

### Commands

```bash
vpn-up start                       # interactive profile menu
vpn-up start "Frankfurt VPN"       # connect directly (scriptable)
vpn-up list                        # list configured profiles
vpn-up add-profile                 # guided profile creation (+ secret, + pin)
vpn-up remove-profile "Old VPN"    # remove profile + secret + logs + service
vpn-up status                      # all running profiles, gateways, uptime
vpn-up logs -f                     # follow the connection log
vpn-up stop                        # stop all VPNs (or: stop "Frankfurt VPN")
```

Each profile keeps its own log and PID/state files under `~/.config/vpn-up`, so `status`, `stop`, and `logs` are profile-aware. You can connect multiple different profiles at once; starting the same profile twice is refused. Whether two tunnels coexist cleanly still depends on the routes and DNS settings pushed by their gateways — split-tunnel or non-overlapping routes are the safest fit.

### TOTP authenticator-app 2FA

For gateways that prompt for a time-based one-time code (Google Authenticator, Authy, a hardware TOTP token), store the base32 seed once and `vpn-up` generates the current code at connect time:

```bash
vpn-up set-secret "Work VPN" token_secret   # paste the base32 seed
```

…then set `<tokenMode>totp</tokenMode>` on the profile (the `add-profile` wizard offers this as a 2FA choice). Requires **`oathtool`** (`brew install oath-toolkit` / `apt install oathtool`; shown by `vpn-up doctor`).

- The **seed stays in your keychain** — it's never passed to openconnect's argv or written to disk; only the short-lived 6-digit code is sent (on stdin), the same path as a Duo passcode.
- Because no interaction is needed, a TOTP profile is the **one 2FA method that can run as a login service** with auto-reconnect (Duo passcode and SSO can't).
- Security note: storing the TOTP seed beside the password in the same keychain is effectively "1.5-factor" — it's opt-in.

### SSO / external-browser login

Some gateways don't accept a username/password on the command line at all — they force a real browser window for a SAML/SSO login (Okta, Azure AD, Ping Identity), often wrapping an embedded **Duo** iframe. `vpn-up` supports this via OpenConnect's external-browser mode.

Mark a profile as SSO — either answer **yes** to the "Use SSO / browser-based login?" prompt in `vpn-up add-profile`, or set `<authMode>sso</authMode>` in the profile XML:

```xml
<VPN>
  <name>Work SSO</name>
  <protocol>anyconnect</protocol>   
  <host>vpn.example.com</host>
  <authMode>sso</authMode>
</VPN>
```

Then connect normally:

```bash
vpn-up start "Work SSO"
```

OpenConnect opens your browser to the identity provider; you complete the login (including Duo) there, and the tunnel comes up. Notes:

- **Requires openconnect ≥ 9.0** (when `--external-browser` landed). `vpn-up doctor` reports your version and whether SSO is available.
- **Runs in the foreground** — `BACKGROUND` is ignored, and an SSO profile **cannot run as a login service** (`service install` refuses it) because it needs an interactive desktop session. No password is stored or piped for SSO profiles.
- **Linux + sudo caveat:** openconnect runs as root, so a root-spawned browser may not reach your desktop session. If the browser doesn't appear, point `vpn-up` at a session-aware opener:

```bash
  # ~/bin/vpn-up-browser  (chmod +x)
  #!/bin/sh
  exec sudo -u "$SUDO_USER" xdg-open "$@"
  ```
  ```bash
  export VPN_UP_EXTERNAL_BROWSER="$HOME/bin/vpn-up-browser"
  ```

`VPN_UP_EXTERNAL_BROWSER` overrides the opener command (default: `open` on macOS, `xdg-open` on Linux, or the bundled `openconnect-external-browser` helper if installed).

### Run as a login service (auto-reconnect)

```bash
vpn-up service install "Frankfurt VPN"    # connect at login, reconnect on drop
vpn-up service status
vpn-up service uninstall "Frankfurt VPN"
```

Uses a launchd user agent on macOS and a systemd user unit on Linux; the service manager supervises openconnect in the foreground and relaunches it if the tunnel drops (30s throttle). Requirements:

- the [passwordless sudoers rule](#passwordless-sudo-optional) — there is no TTY to type a sudo password into
- the profile's password stored in the secrets backend
- a non-interactive 2FA method (`push`, `phone`, `sms` — not `passcode`)

### Hooks

Drop executable scripts into `~/.config/vpn-up/hooks/connected.d/` or `~/.config/vpn-up/hooks/disconnected.d/` and they run (in name order) when a tunnel comes up or goes down. Hooks receive `VPN_EVENT`, `VPN_NAME`, and `VPN_HOST` in their environment (never the password). Because hooks are executable code, a hook is **skipped unless it is owned by you and not group/world-writable** — same rule as the config file. Hook failures are reported but never block the VPN.

```bash
mkdir -p ~/.config/vpn-up/hooks/connected.d
cat > ~/.config/vpn-up/hooks/connected.d/10-hello <<'EOF'
#!/bin/sh
echo "$(date): $VPN_NAME up ($VPN_HOST)" >> "$HOME/vpn-history.log"
EOF
chmod 700 ~/.config/vpn-up/hooks/connected.d/10-hello
```

### Shell completion

Homebrew installs completion automatically. For manual installs:

```bash
# bash (~/.bashrc)
source /path/to/vpn-up-for-openconnect/completions/vpn-up.bash

# zsh (~/.zshrc)
autoload -U +X bashcompinit && bashcompinit
source /path/to/vpn-up-for-openconnect/completions/vpn-up.bash
```

Completes commands and profile names (spaces handled).

### Secrets management

```bash
vpn-up set-secret "Frankfurt VPN" password
vpn-up delete-secret "Frankfurt VPN" password
```

Passwords are stored in the OS keychain/keyring (or an encrypted vault as fallback) — never in files, never in the process table, never exported to child processes.

### Passwordless sudo (optional)

`openconnect` needs root. By default you'll get the normal `sudo` prompt. Never store your sudo password anywhere; if you want non-interactive runs, grant passwordless sudo for `openconnect` **only**:

```bash
# macOS (Homebrew):
echo "$USER ALL=(root) NOPASSWD: /opt/homebrew/sbin/openconnect" | sudo tee /etc/sudoers.d/vpn-up
# Linux:
echo "$USER ALL=(root) NOPASSWD: /usr/sbin/openconnect" | sudo tee /etc/sudoers.d/vpn-up
sudo chmod 440 /etc/sudoers.d/vpn-up
sudo visudo -cf /etc/sudoers.d/vpn-up   # validate
```

> Verify the `openconnect` path with `command -v openconnect`. Keep the rule scoped to the one binary — do not add broad commands like `kill` here. Stopping the VPN will still ask for your sudo password; that's intentional.

### Certificate pinning

```bash
vpn-up pin vpn.example.com          # print the pin
vpn-up pin --save "Frankfurt VPN"   # write it into the profile
```

Prints the gateway's `pin-sha256:...` value for `<serverCertificate>`, or saves it into the profile directly with `--save`. If no pin is configured, the gateway's certificate **must** validate against the system trust store or the connection is refused (fail closed). Legacy SHA1 pins still work but print a deprecation warning. Verify any pin out-of-band with your VPN administrator before trusting it.

### Diagnostics

```bash
vpn-up doctor
```

### Advanced: extra openconnect arguments

Need an openconnect flag `vpn-up` doesn't model (`--no-dtls`, `--os=win`, `--csd-wrapper`, an HTTP/SOCKS proxy, MTU, `--reconnect-timeout`, …)? Set `<extraArgs>` on the profile (or answer the optional "Extra openconnect arguments" prompt in `add-profile`); the value is appended verbatim to the openconnect command, just before the gateway host:

```xml
<extraArgs>--no-dtls --reconnect-timeout 30</extraArgs>
```

- Tokenized with `xargs`, so quotes are respected (`"--csd-wrapper=/path with space"` stays one argument) — and **never** `eval`'d.
- Avoid flags `vpn-up` already manages — `--protocol`, `--user`, `--passwd-on-stdin`, `--background`, `--servercert`, `--authgroup`, `--pid-file`, `--external-browser`, `--token-mode`/`--token-secret`. Duplicating one prints a warning (it may conflict) but is still passed.
- ⚠️ openconnect runs as **root**; some flags execute programs as root (e.g. `--csd-wrapper`, `--script`). Only put flags here that you'd be comfortable running under `sudo` yourself.

**Split-tunnel routing:** to send only some subnets through the VPN (and the rest direct), set `<extraArgs>--script "vpn-slice 10.0.0.0/8 host.corp"</extraArgs>` — [vpn-slice](https://github.com/dlenski/vpn-slice) is a drop-in `vpnc-script` replacement. Full recipe (include/exclude syntax, hooks alternative, caveats): [Split-tunnel routing](https://sorinipate.github.io/vpn-up-for-openconnect/split-tunnel/).

### Client-certificate authentication

Authenticate with an **X.509 client certificate** — a file or a **PKCS#11** smartcard / **YubiKey PIV** — on its own (cert-only) or alongside a password/SSO. Set `<clientCertificate>` (and `<clientKey>` if the key is separate); each is a file path or a `pkcs11:` URI:

```xml
<clientCertificate>/etc/vpn/me.pem</clientCertificate>

<clientCertificate>pkcs11:manufacturer=piv_II;id=%01;type=cert</clientCertificate>
```

- The cert **path/URI is not a secret** (it stays in the XML); a key **passphrase or PKCS#11 PIN is** — it never goes on the command line. An encrypted key/token prompts interactively, or store a PKCS#11 PIN for unattended use: `vpn-up set-secret "Work" key_password` (fed via a transient `pin-source` file, never argv).
- For a [login service](#run-as-a-login-service-auto-reconnect), use a PKCS#11 token with a stored PIN, or an unencrypted `0600` key file (a passphrase-protected file key can't run unattended — there's no TTY to prompt on).
- `vpn-up doctor` reports PKCS#11 (`p11-kit`) availability. Full guide: [docs/client-certificate-auth](https://sorinipate.github.io/vpn-up-for-openconnect/client-certificate-auth/).

### HTTP/SOCKS proxy

Reach the gateway through a proxy by setting `<proxy>` on the profile (or answer the optional proxy prompt in `add-profile`). It's passed to openconnect's `--proxy`:

```xml
<proxy>http://proxy.corp:8080</proxy>

<proxy>socks5://127.0.0.1:1080</proxy>
```

- The proxy URL is an **identifier, not a secret** — it lives in the profile XML. ⚠️ Avoid embedding `user:pass@` in the URL: like any argument, it would be visible in the process table. Prefer a proxy that doesn't require inline credentials.

---

## ⚙️ Configuration

All user state (config, profiles, secrets vault, logs, PID files) lives in **`~/.config/vpn-up`** (override with `VPN_UP_HOME` or `XDG_CONFIG_HOME`), so updating or deleting the program directory never touches your data. Legacy files from the old in-repo `config/` directory are migrated automatically on first run.

### Main config — `~/.config/vpn-up/vpn-up.command.config`

```bash
readonly QUIET=TRUE          # openconnect output verbosity
readonly BACKGROUND=TRUE
readonly SHOW_BANNER=TRUE    # ASCII banner on start (independent of QUIET)
readonly NOTIFICATIONS=TRUE  # desktop notification on connect/disconnect
readonly ENCRYPTION_ENABLED=TRUE
```

> ⚠️ `ENCRYPTION_KEY` is intentionally ignored. OS keychain/keyring is always preferred. The OpenSSL vault prompts for a passphrase when needed.

### VPN profiles — `~/.config/vpn-up/vpn-up.command.profiles`

Seeded from [config/vpn-up.command.profiles.default](config/vpn-up.command.profiles.default) on first run, or created via `vpn-up add-profile`:

```xml
<VPNs>
  <VPN>
    <name>Frankfurt VPN</name>
    <protocol>anyconnect</protocol>
    <host>frankfurt.example.com</host>
    <authGroup>SimplicaEmployees</authGroup>
    <user>your.username</user>
    <password></password>
    <duo2FAMethod>push</duo2FAMethod>
    <serverCertificate>pin-sha256:BASE64_HASH</serverCertificate>
    <authMode>password</authMode>
    <tokenMode>totp</tokenMode>
    <extraArgs>--no-dtls</extraArgs>
    <clientCertificate>/etc/vpn/me.pem</clientCertificate>
    <clientKey></clientKey>
    <proxy>http://proxy.corp:8080</proxy>
  </VPN>
</VPNs>
```

Supported tag aliases: `username`/`user`, `group`/`authGroup`, `duoMethod`/`duo2FAMethod`. The `<password>` field is deprecated: plaintext values are migrated to the secrets backend and blanked in the XML automatically on first use — prefer `vpn-up set-secret`. A `duo2FAMethod` of `passcode` prompts for the one-time code at connect time. `<authMode>` is `password` (default) or `sso` for [browser-based SAML/SSO login](#sso--external-browser-login). `<tokenMode>` is empty (default) or `totp` for [authenticator-app 2FA](#totp-authenticator-app-2fa). `<extraArgs>` passes extra openconnect flags verbatim — see [Advanced: extra openconnect arguments](#advanced-extra-openconnect-arguments). `<clientCertificate>`/`<clientKey>` enable [client-certificate authentication](#client-certificate-authentication) — a file path or a PKCS#11 URI; a key passphrase/PIN goes in the secrets backend (`key_password`), never the XML. `<proxy>` routes the connection through an [HTTP/SOCKS proxy](#httpsocks-proxy).

---

## 🗺 Roadmap

**Under consideration** (open an issue if you need one of these):

- Yubikey OATH (HOTP) token support (TOTP authenticator codes are already supported — see [TOTP authenticator-app 2FA](#totp-authenticator-app-2fa) — as is a Yubikey **PIV client certificate** via [client-certificate authentication](#client-certificate-authentication))

**Explicitly out of scope:** Windows support, GUI, and **RSA SecurID** — importing a SecurID token requires passing the token secret to openconnect on the command line (`--token-secret`), which would break VPN Up's rule of never putting secrets in argv (the same reason TOTP is fed on stdin rather than via `--token-secret`).

**Known behavior:** some AnyConnect gateways emit an initial `Unexpected 404 result from server` — this is benign if the connection proceeds successfully. Simultaneous full-tunnel VPNs can also fight over the default route or DNS. VPN Up tracks and controls each OpenConnect process independently, but OpenConnect and the VPN gateways still own route/DNS installation.
