How To Fix ifenslave: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu ifenslave is provided by ifenslave package.

ifenslave is:

This is a tool to attach and detach slave network interfaces to a bonding device. A bonding device will act like a normal Ethernet network device to the kernel, but will send out the packets via the slave devices using a simple round-robin scheduler. This allows for simple load-balancing, identical to “channel bonding” or “trunking” techniques used in switches.

The kernel must have support for bonding devices for ifenslave to be useful. This package supports 2.6.x kernels and the recent 3.x.x kernels.

To fix this problem, we can install more using the command below.

sudo apt-get -y install ifenslave

sudo apt -y install ifenslave
