Aeris License Manager

Licensing library for Keysight Aeris products (aeris-channel, aeris-scene, aeris-netplanner, aeris-6gr). Product packages install it automatically as a dependency.

---

Requirements

• Python 3.11 or later
• A valid aeris.lic license file from Keysight
• Supported platforms for this release: Windows and Linux (macOS not currently supported)

---

Installation

pip install aeris-channel   # or aeris-scene, aeris-netplanner, etc.

For normal product use, aeris-license is installed automatically as a dependency. Install it directly when you are setting up the license daemon.

---

Activating your license

Save the aeris.lic file you received from Keysight to a permanent location, then set the AERIS_LICENSE_FILE environment variable to that path.

Recommended locations:

• All platforms: ~/.keysight/aeris.lic
• Windows: C:\Program Files\Keysight\aeris.lic
• Linux: /etc/keysight/aeris.lic

Windows (PowerShell — permanent, per user):

[System.Environment]::SetEnvironmentVariable(
    "AERIS_LICENSE_FILE",
    "C:\Program Files\Keysight\aeris.lic",
    "User"    # scope — saves to current user's profile, no admin rights needed
)

Linux:

echo 'export AERIS_LICENSE_FILE=/etc/keysight/aeris.lic' >> ~/.bashrc
source ~/.bashrc

If AERIS_LICENSE_FILE is not set, the package searches these locations in order:

1. aeris.lic in the current working directory (the folder you launch Python from)
2. ~/.keysight/aeris.lic
3. The platform-specific location above

Note: the search is not relative to your virtual environment or the installed package. Copying aeris.lic into a venv folder (for example .venv/ or site-packages/) will not be found. Use AERIS_LICENSE_FILE (recommended) or one of the locations above.

Restart your terminal or IDE, then import the product package. Product packages call aeris_license.load_license() as part of their startup and verify the license automatically. The aeris-license package itself does not verify a license merely because it is imported.

Quick verify (node-locked):

python -m aeris_license check
python -c "import your_product_package"  # replace with your installed Aeris product package

---

Diagnosing a license problem

python -m aeris_license check

This prints the license file location, expiry date, licensed products, and whether the current machine's MAC address is authorised.

Floating license server (multi-seat teams)

If your organisation uses a shared floating license, your IT administrator sets up the Aeris License Manager daemon on a central server. The signed floating license lives only on the server — workstations do not receive a license file.

Each workstation sets AERIS_LICENSE_SERVER=host:port to point at the daemon. Clients do not install or run the daemon, and they do not need node-locked licenses. At startup load_license() checks out a seat from the server.

For this release, floating licenses are MAC-bound. For production deployment, use a native OS service:

• Windows: NSSM service via install_windows.ps1
• Linux: systemd service (aeris-license.service)

The server setup guide for your IT administrator is bundled with this package. On the license server, first install the daemon extra:

pip install "aeris-license[daemon]"

Then the bundled server files are available from the installed package:

python -c "import importlib.resources as r, aeris_license.server as s; print(r.files('aeris_license.server'))"

The same package directory also contains install_windows.ps1 and aeris-license.service for server setup.

On Linux, /opt/keysight/aeris_license/ is the recommended daemon service directory. Because it is not a default license search path, set AERIS_LICENSE_FILE explicitly when the license is stored there.

Or start the daemon directly on the license server, specifying the license file explicitly:

AERIS_LICENSE_FILE=/opt/keysight/aeris_license/aeris.lic aeris-license-daemon

Quick verify (floating):

# On server host
curl http://localhost:27010/v1/health

# On client workstation (no local .lic file)
export AERIS_LICENSE_SERVER=<license-server-host>:27010
python -m aeris_license check
python -c "import your_product_package"  # replace with your installed Aeris product package

---

Requesting a license

Contact support.aeris@keysight.com with:

1. Your name and company

2. The MAC address of your workstation (or license server for floating)

   Windows (PowerShell):

   getmac /v /fo list | Select-String "Physical Address|Connection Name"
   # or
   ipconfig /all | Select-String "Physical Address"
   

   Linux:

   ip link show | grep "link/ether"
   

   Python (reference command; requires psutil):

   python -c "
   import psutil
   for nic, addrs in psutil.net_if_addrs().items():
       for a in addrs:
           if a.family == psutil.AF_LINK and a.address not in ('', '00:00:00:00:00:00'):
               print(nic, a.address)
   "
   

3. The product(s) and features you need

4. Preferred license term (trial / annual / perpetual)
