ETHERSTAT(1)

NAME
etherstat - Ethernet packet filter (PUP, Ethertalk) connections and statistics

SYNOPSIS
etherstat

DESCRIPTION
Etherstat is used to print the internal data structures for the Ethernet packet filter, enet(4). It will show information for all network protocols that use the packet filter. Currently this includes Ethertalk and PUP. Etherstat prints information about each open connection, and then a summary. The information is organized by device. Each packet filter device corresponds to an Ethernet interface (e.g. ie0, le1). Etherstat will print both the minor device number and the corresponding Ethernet interface name.

The Ethernet packet filter allows software to specify which packets it is interested in using "filters" described as Polish operator strings. In the most general case, Etherstat will print the filter associated with each connection as a Polish operator string. However it will recognize a few commonly used operator strings, and print them in a more human-readable form, as Appletalk port numbers for Ethertalk connections, and as PUP address specifications for PUP connections.
