Re: [ns] Pcap/BPF network object in NS emulation

[Alefiya Hussain <alefiyah@catarina.usc.edu>]

The Network/Pcap/Live uses the standard BSD packet capture library and
berkeley packet filter (bpf).

Hence it can capture all types of packets and if not restricted to telnet
or ftp. Please refer to "man tcpdump" for format for filter strings.

all the best,
alefiya
