Parameter license_key_id 

Optional parameter. There can be several license_key_id parameters in this section. They define a prioritized list of license keys. The first entry has the highest priority. If no key with this ID is available, the next key in the list will be tried. If a higher priority key becomes available, the emulator will switch to this license at the next periodic license check.

Syntax:

license_key_id "key-id-prio1"

Optional parameter. There can be several license_id parameters in this section. They define a prioritized list of product license IDs. The first entry has the highest priority. If no key with this product license ID is available, the next product license ID in the list will be attempted. If a higher priority license becomes available, the emulator will switch to this license at the next periodic license check.

Syntax:

license_id "lic-id-prio1"

Serial port option
Description
type

The serial port type determines the protocol used on the serial port. Possible values are:

  • socket: the port is set to telnet raw mode.
  • telnet: the port supports the telnet protocol.
  • device: indicates that the emulated serial line is connected to a physical terminal on the host.
port

Each port is mapped to a TCP socket on the emulator host or to a physical line. This parameter defines the TCP port used or the name of the physical device. A TCP port number must be unique on the host system.

A TCP port number is specified as "<where-to-listen>:<portnumber>". It requires a port type of socket or telnet.

Possible values for where-to-listen:

  • Empty:
    • If the port number is specified without a colon (:), the console will only be accessible on the localhost address. Equivalent lo:<portnumber>.
    • If the port number is specified with a colon, the console process will listen on all host interfaces.
  • Interface name: the console process will only listen on the specified host interface.
  • IP address: the console process will only listen on host IP address.

Default values:

  • ":30000" for line 1
  • ":30002" for line 2

A physical device is specified as "<device-file>". It requires a port type of device.

Example:

  • "/dev/ttyS0"
  • "/dev/ttyUSB0"
commandThis parameter is optional. It can be used to specify a terminal emulation program that is started automatically when the emulated system is started. Charon-PAR provides preconfigured profiles for PuTTY (HPA-Socket HPA-Telnet HPA-Telnet-VT100) that can be used to connect to the emulated system via a serial line.

...

  • A TAP interface can either be created by the user or will be created automatically by the emulator if it does not already exist.
  • For automatically created TAP interfaces, the user can specify a name or let the emulator select a name.
  • A automatically created TAP interface is not automatically added to a bridge, this must be configured via the initialize_command.
  • An automatically created TAP interface is deleted automatically upon emulator stop.

Notes for network configurations on VMware:

  • ESXi has configuration parameters that improve security but may block certain emulator NIC configurations.
  • One configuration option allows or blocks promiscuous mode (the default mode of operation for Charon-PAR guest NICs).
  • Other configuration options allow or block the change of a MAC address or the use of a different, additional MAC address on the same NIC (MAC address changes, Forged transmits).

By default, emulated models have one Ethernet device. Depending on the model, more Ethernet devices can be added.
