There is one really good command in Linux/UNIX called man :-)
man tcpdump
.....
Under Linux:
You must be root or tcpdump must be installed setuid to root
(unless your distribution has a kernel that supports capability
bits such as CAP_NET_RAW and code to allow those capability
bits to be given to particular accounts and to cause those bits
to be set on a user\u2019s initial processes when
they log in, in
which case you must have CAP_NET_RAW in order to capture and
CAP_NET_ADMIN to enumerate network devices with, for example,
the -D flag).
