SYNOPSIS
pppoe-discovery [options]
DESCRIPTION
pppoe-discovery sends PPPoE Active Discovery Initiation (PADI) packets on a network interface to find available PPPoE access concentrators. It reports the names and services offered by any responding concentrators without actually establishing a connection.
This diagnostic tool is useful for verifying that a DSL modem or network is properly configured and that the ISP's access concentrator is reachable before attempting a full PPPoE connection.
