No, it is not. There is no need to painstakingly try every single implementation of ping: some people here know how to actually implement ping, they know what the various system calls do and how they interact with firewall rules and network error feedback. And based on that knowledge, they can tell you: EPERM can be caused by firewall rules on the sendmsg() system call, but not on the socket() system call, and the original error message states it happens on the socket() system call. Note that nobody blames you for not knowing that, it is not a mandatory knowledge for using Debian, and I am sure there are other things you know about Debian that few other people know. But try to get the feel of the wind and understand that, lacking the corresponding knowledge, you should take their word for it. Regards, -- Nicolas George
