How to Add CHAP Support to the PPP Configuration Files (Dial-in Server)

  1. Log in to the dial-in server as superuser.

  2. Modify the /etc/ppp/options file.

    Add the options that are shown in bold for CHAP support.

    # vi /etc/ppp/options
    name CallServe

    name CallServe

    Defines CallServe as the CHAP name of the user on the local machine (dial-in server)


    Makes the local machine authenticate callers before establishing the link 


    Requires peers to provide CHAP credentials before the link can be established

  3. Create the remaining PPP configuration files to support the trusted callers.
