I'm using a Debian 9 image on a virtual machine. The ping command is not installed. When I run:
sudo apt-get install ping
It asks me:
Package ping is a virtual package provided by: iputils-ping 3:20161105-1 inetutils-ping 2:1.9.4-2+b1 You should explicitly select one to install.
Why is there two ping utilities? What are the differences between them? Is there some guidelines to choose one version over the other? What are the implications of this choice? Will all scripts and programs be compatible with both versions?
