Which Version of Solaris PPP to Use

Solaris PPP 4.0 is the PPP implementation that is supported. The Solaris 9 release and later releases do not include the earlier Asynchronous Solaris PPP (asppp) software. For more information, refer to Chapter 9, Migrating From Asynchronous Solaris PPP to Solaris PPP 4.0 (Tasks).

Why Use Solaris PPP 4.0?

    If you currently use asppp, consider migrating to Solaris PPP 4.0. Note the following differences between the two Solaris PPP technologies:

  • Transfer modes

    asppp supports asynchronous communications only. Solaris PPP 4.0 supports both asynchronous communications and synchronous communications.

  • Configuration process

    Setting up asppp requires configuring the configuration file, three UUCP files, and the ipadm command. Moreover, you have to preconfigure interfaces for all users who might log in to a machine.

    Setting up Solaris PPP 4.0 requires defining options for the PPP configuration files, or issuing the pppd command with options. You can also use a combination of both the configuration file and command-line methods. Solaris PPP dynamically creates and removes interfaces. You do not have to directly configure PPP interfaces for each user.

  • Solaris PPP 4.0 features not available from asppp

    • MS-CHAPv1 and MS-CHAPv2 authentication

    • PPP over Ethernet (PPPoE), to support ADSL bridges

    • PAM authentication

    • Plug-in modules

    • IPv6 addressing

    • Data compression that uses Deflate or BSD compress

    • Microsoft client-side callback support

Solaris PPP 4.0 Upgrade Path
