This procedure uses the PPP configuration files that were introduced in How to Define Communications Over the Serial Line as examples. The procedure configures the dial-out machine that belongs to user2, as shown in Figure 26–3.
Log in to the dial-out machine as superuser.
Modify the /etc/ppp/options file.
The next /etc/ppp/options file contains options for PAP support, which are shown in bold.
#vi /etc/ppp/options lock nodefaultroute name user2 auth require-pap |
Sets user2 as the PAP name of the user on the local machine. If the login option is used, the PAP name must be the same as the user's UNIX user name in the password database.
States that the dial-out machine must authenticate callers before establishing the link.
Requires peers to provide PAP credentials when returning the call from the dial-out machine.
Create an /etc/ppp/peers/peer-name file for the remote machine myserver.
The next sample 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.
# cd /etc/ppp # mkdir peers # cd peers # vi 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
