Calling the Dial-in Server

You establish a dial-up PPP link by having the dial-out machine call the dial-in server. You can instruct the dial-out machine to call the server by specifying the demand option in the local PPP configuration files. However, the most common method for establishing the link is for the user to run the pppd command on the dial-out machine.

Before you proceed to the next task, you should have done either or both of the following:

ProcedureHow to Call the Dial-in Server

  1. Log in to the dial-out machine by using your regular user account, not root.

  2. Call the dial-in server by running the pppd command.

    For example, the following command initiates a link between the dial-out machine and dial-in server myserver:

    % pppd 57600 call myserver

    Starts the call by invoking the pppd daemon


    Sets the speed of the line between host and modem

    call myserver

    Invokes the call option of pppd. pppd then reads options in the file /etc/ppp/peers/myserver, which was created in How to Define the Connection With an Individual Peer

  3. Contact a host on the server's network, for example, the host lindyhop that is shown in Figure 16–1:

    ping lindyhop

    If the link is not working correctly, refer to Chapter 21, Fixing Common PPP Problems (Tasks).

  4. Terminate the PPP session:

    % pkill -x pppd
