Finds for the presence of address which can be bound to the sandbox given an address range, i.e.
- Let's say 3 address aliases is required.
- The address range is 192.168.128.0/24
These addresses requires setup using ifconfig as such (MacOS example):
sudo ifconfig lo0 alias 192.168.128.1 255.255.255.0
sudo ifconfig lo0 alias 192.168.128.2 255.255.255.0
sudo ifconfig lo0 alias 192.168.128.3 255.255.255.0
This command will check if 192.168.128.1, 192.168.128.2, and 192.168.128.3 can be bound. The check is done by
binding a socket to each of these address using a test port.
If the number of required address is not present, provide the commands so the end user is able to copy-paste and
execute these commands.
:param nr_of_addrs: number of address aliases required
:param addr_range: the range of address which is available to core and agent to bind to.
The address is specified in the CIDR format, i.e. 192.168.128.0/24
