SCAPY send packet error OSError: [Errno 97] Address family not supported by protocol

Question

I hit the below error when trying to send packet using:

• Ubuntu: release 18.04
• Python: 3.6.6
• scapy version: 2.4.0

>>> send(IP(dst="192.168.1.1")/ICMP())
---------------------------------------------------------------------------

    408         self.ins.setsockopt(socket.SOL_SOCKET, socket.SO_RCVBUF, 0)
    409         if iface:

OSError: [Errno 97] Address family not supported by protocol

Is there anything that might cause this on a fresh install of Scapy?

Answer 1

That probably would happen if you use VM or Windows Subsystem for Linux. Try standard installation, that solved the same problem for me.
