You establish a dial-up PPP link by having the dial-out system call the dial-in server. You can instruct the dial-out system 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 system.
Before you proceed to the following task, you should have completed either or both of the following tasks:
For example, the following command initiates a link between the dial-out system and dial-in server myserver:
$ pppd 57600 call myserver
pppd starts the call by invoking the pppd daemon.
57600 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,
For example, contact the host lindyhop from Sample Dial-Up Link.
$ ping lindyhop
If the link is not working correctly, refer to Troubleshooting Common Point-to-Point Protocol Problems.
$ pkill -x pppd
If you have followed all the procedures in this chapter, you have completed the configuration of the dial-up link. The following list provides references to related information.
