snoopy - spy on Ethernet packets
snoopy [ -abceiltup9 ] [ -np ] [ -N count ]
Snoopy displays the header and first 20 data bytes of packets received from the local Eth-
ernet. The packets displayed depend on the options chosen. The following options each
select packets from a particular protocol. If more than one flag is given, packets from
all those protocols are displayed.
e all Ethernet packets
By default all addresses are translated into system names. The option n suppresses this.
Snoopy runs in promiscuous mode by default, displaying all packets it can capture from the
Ethernet. The option p causes only packets sent to or from the system snoopy is running
on to be displayed.
Option 9 causes the data of TCP and IL messages to be interpreted and displayed as 9P mes-
sages. The N option sets the count (default 20) of the number of bytes to dump in hexa-
decimal from each packet.
The CPU servers do not take well to running in promiscuous mode. If run on them, snoopy
may kill their Ethernets.
