# Note PANOS API KEY and IP address needs to be set prior to running.

# The following variables exported from environment will be used.

# If not set then values previously saved in domain.conf file are used.

# Firewall admin with superuser and IP address is required.

# REQURED:
|
|
# export PANOS_HOST="" # required
|

# export PANOS_USER="" # required

|

# Method 1: Password (RECOMMENDED)

# Method 2: API KEY
