Hi! Is it possible to use libpcap without root privileges? In our case, we are testing an IP-stack in a "simulated" environment, this means the IP-stack-program has a "special" socket interface where we send and receive IP-packets from. For example:The traffic generator runs on 127.0.0.1:1234 (we will probably use scapy or netexpect as traffic generator and analyzer)And the simulated IP-stack program runs on the same machine on 127.0.0.1:4321 The IP-packets go directly between the traffic generator process and the IP-stack-process withouth using the NIC. Since the NIC is not used in this scenario libpcap shouldn't need root privileges, correct? Brs,Markus- This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
