Severity: normal
Hi,
the following scapy 2.3.2 simple script:
=====================
#!/usr/bin/env python3
from scapy.all import *
pkt = IP()
pkt.ttl = 2
conf.L3socket = L3RawSocket
sr1(pkt)
=====================
Produces this in my debian system:
Begin emission:
ERROR: --- Error in child 3589
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/scapy/sendrecv.py", line 89, in sndrcv

r = pks.recv(MTU)
File "/usr/lib/python3/dist-packages/scapy/supersocket.py", line 94, in recv
from arch import get_last_packet_timestamp
ImportError: No module named 'arch'
I installed it from the debian archive:
% aptitude install python3-scapy
What is even more weird is that executing the same script steps in the
scapy CLI they work fine:
% sudo scapy
