TCP/IP and Data Communications Administration Guide

Inbound Connections Scenario

The host initiating the inbound communication logs in, which invokes the /usr/sbin/aspppls login service. Then the following events occur:

  1. The login service connects to the link manager through the /tmp/.asppp.fifo file.

  2. The login service provides the link manager with information such as the login name used by the endpoint at the other end of the link.

  3. The link manager uses this login name to find a corresponding configured path in the configuration file.

  4. The link manager then configures and initiates PPP.

  5. The data-link layer is established, and the PPP modules on the peer hosts start communicating.

  6. The link manager enables IP over the link.

The link manager then monitors the connection until an event occurs such as an idle time out, line disconnect, or error condition. When any of these events occur, the link manager disconnects from the peer and returns to the idle state.
