NAME

kathara-lconfig - Attach network interfaces to a running Kathara device of a Kathara network scenario

SYNOPSIS

kathara lconfig [-h] [-d DIRECTORY] -n DEVICE_NAME (--add <CD[/MAC_ADDR]> [<CD[/MAC_ADDR]> ...] | --rm CD [CD ...])

DESCRIPTION

Manage the network interfaces of a running Kathara device in a network scenario. The affected device is identified by DEVICE_NAME, which is the name of the running device in the network scenario.

OPTIONS

-h, --help
Show a help message and exit.
-d DIRECTORY, --directory DIRECTORY
Specify the folder containing the network scenario.

Manage the network interfaces of running devices in a Kathara network scenario that is located inside DIRECTORY. If no -d option is provided, assume the network scenario is located in the current directory.

-n DEVICE_NAME, --name DEVICE_NAME
Name of the device to configure.
--add <CD[/MAC_ADDR]> [<CD[/MAC_ADDR]> ...]
Specify the collision domain to be connected to the device:

CD: The name of the collision domain to which the specified interface must be connected. Note that the name of the collision domain must not contain spaces (" "), commas (",") and dots (".").

/MAC_ADDR: An optional parameter to specify the MAC address of the interface (MAC address must be in the format XX:XX:XX:XX:XX:XX). If MAC_ADDR is not provided, Kathara will assign a random one.

Equip the device with an additional network interface attached to a (virtual) collision domain whose name is CD. The number of the resulting network interface is generated incrementing the number of the last network interface used by the device.

--rm CD [CD ...]
Specify the collision domain to be disconnected from the device.

Disconnect the device from the collision domain whose name is CD and remove the corresponding interface.

EXAMPLES

Connect pc1 to collision domain X and Y (with random MAC addresses):

kathara lconfig -d path/to/network_scenario -n pc1 --add X Y

Connect pc1 to collision domain X with the specified MAC address:

kathara lconfig -d path/to/network_scenario -n pc1 --add X/00:00:00:00:00:01

Disconnect pc1 from collision domain X and remove the corresponding interface:

kathara lconfig -d path/to/network_scenario -n pc1 --rm X

REPORTING BUGS

Report bugs opening an issue on the official GitHub repository where the development and maintenance is primarily done.
Issues which are security relevant should be disclosed privately to the Kathara mailing list. You do not have to be subscribed to the list to send a message there.
When reporting a bug, remember to write used commands, eventually attach your network scenario, and include the output of kathara-check(1) in order to make possible to reproduce the bug.
