PPP comes with HP-UX 10.30 and later.

The PPP manual "Installing and Adminsistering PPP" (Part No. B2355-90137)
can be viewed online at:

  o <http://docs.hp.com/en/B2355-90137/>

Or purchased in hardcopy form from:

  o <http://software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=B8679BA:B2355-90137>

Follow these steps to configure PPP on your 11.x system:

     1. Execute the GSP (Guardian Service Processor) DR command to disable
        the remote.

        Note: It is not necessary to run this command if the modem is on
              the MUX (mulitplexer) port.

     2. Modify the 19200 entry in /etc/gettydefs to include the following
        information:

         19200 #B19200 HUPCL CS8 SANE ISTRIP IXANY TAB3
                 #B19200 SANE CS8 ISTRIP IXANY TAB3 HUPCL
                 #login: #19200

     3. Create a device file for calling into a remote console port:

         mksf -C tty -H 0/0/4/0 -m 0x000202 /dev/ttyd0p2

         Note: For MUX cards, use SAM (System Administration Manager) or
                use the following command:

                mksf -d <mux_driver> -H <hw_path> -I <instance> \
                     -p <port_number> -a 2

     4. Add the following line in /etc/inittab:

         a1:3:respawn:/usr/bin/pppd <hostname>:<remote_host_IP> netmask
         <netmask> idle 150 requireauth <port_device_file> 19200

         Note: See the pppd(1) man page for more information.

     5. Re-initialize the /etc/inittab file so that the changes will take
        effect:

         init q

     6. Edit /etc/ppp/Auth against authentication of dial-up networking
        users:

         <username> <password_in_cleartext> ...
         ... <optional_address_restrictions>

         Note: Please see the ppp.Auth(4) man page for more
                information.

     7. Next, test the ppp connection from a PC. Launch:

         Start
          --> Programs
               --> Accessories
                    --> Dial-up Networking

         Use the same username/passwd pair that was entered into the
         /etc/ppp/Auth file.

As for HP-UX 9.x and 10.x, there are a couple options:

  o iij-ppp: a public-domain PPP implementation that has been ported to
             HP-UX

    Unfortunately, the homepage for the HP-UX port of iij-ppp appears to
    no longer exist.

  o Sun/Cobalt/Progressive Systems/Morningstar PPP: Once upon a time, this
    was a fine, supported product.  Due to merger-mania, Sun now owns this
    product, but offers no support for it.  Expect no further development.
    But, you can still buy a license for the product if you ask your Sun
    salesperson.  The product offers PPP and SLiP on HP-UX 9.x or 10.x
    systems.  Works with SecurID[R] cards and dialback modems.

It is a good idea to install the latest Mux/Pty patch before using PPP:

  o 11.11: patch PHNE_27760
  o 11.00: patch PHNE_27788
  o 10.20: patch PHNE_21872
  o 10.10: patch PHNE_20838
  o 10.0x: patch PHNE_9436
