Hi all,
I have been trying to read packets on the loop back
interface. The code in the pcap lib tries to open the
device /dev/lo, when I give the command
tcpdump -i lo1 -V and fails.
The loopback interfaces can be obtained by issueing an
ioctl call or by reading the output of ifconfig -a
option, but I cannot seem to find a way to read the
packets using the tcpdump.
How do I use tcpdump to read packets on all
available interfaces on the system ?
Also, My system doesn't support promiscuous mode at
all.
Thanks,
SN
