This procedure uses as examples the PPP configuration files that were introduced in How to Define Communications Over the Serial Line. The procedure configures the dial-out machine that belongs to user2, as shown in Figure 16–3.
Log in to the dial-out machine as superuser.
The next /etc/ppp/options file contains options for PAP support, which are shown in bold.
# cat /etc/ppp/options lock name user2 auth require-pap
States that the dial-out machine must authenticate callers before establishing the link.
This dial-out machine demands authentication from its peers, even though most dial-out machines do not make this demand. Either way is acceptable.
The next example shows how to add PAP support to the existing /etc/ppp/peers/myserver file that was created in How to Define the Connection With an Individual Peer.
# cat /etc/ppp/peers/myserver /dev/cua/a 57600 noipdefault defaultroute idle 120 user user2 remotename myserver connect "chat -U 'mypassword' -f /etc/ppp/mychat"
The new options in bold add PAP requirements for peer myserver.
Defines user2 as the user name of the local machine
Defines myserver as a peer that requires authentication credentials from the local machine
