So Linux does an excellent job in managing rights per user. You all know the file and process management.
But is it also possible to create a virtual private network interface?
Say Linux user John Doe (jdoe) wants to test network software without being root and disturbing the real netif. Can you create an interface that belongs to jdoe only? Like eth0, eth1 and ethJdoe, making ethJdoe belonging to jdoe.
