Field Description
s= Lists the source address of the packet and the name of the interface (in
parentheses) that received the packet.
d= Lists the destination address of the packet and the name of the interface
(in parentheses) through which the packet is being sent out on the
network.
len Displays the packet’s length.
sending

fragment
sending broad/multicast proto
unroutable
The last part of each line lists the status of the packet.
TCP src= Displays the source and destination ports, the sequence number, the
acknowledgement number, and the window size of the packets in that
TCP packets.
UDP src= Displays the source and destination ports for the UDP packets.
ICMP type= Displays the ICMP type and code.
IP Fragment States that it is a fragment and displays the unique number identifying the
fragment (Ident) and the
offset (in 8-byte units) of this fragment
(fragment offset) from the beginning of the original datagram.
