# This is a working example of ppp.conf.span-isp that uses ppp connections
|
|
# to the same machine through 3 null-modem serial cables.

# cuaD01 <-> cuaD06
|
|
# cuaD00 <-> cuaD07
|
|
#
|
|
# with gettys running on cuaD04, cuaD06 and cuaD07. The gettytab entry
|
|
# for these devices has a pp= capability that references a script that
|
|
# says:
|
|
#
|
|
# #! /bin/sh
|
|
# tty=$(tty)
|
|
# exec /usr/sbin/pppin -direct isp-in-${tty#${tty%?}}
|
|
#
|
|
# The whole thing is brought up with these commands:
|
|
#
|
|
# ppp -b isp1
|
|
# ppp -b isp2
|
|
# ppp -b isp3
|
|
#
|
|
# Something rather strange happens here.
|
|
# If you connect to the vpn-in diagnostic socket with ``pppctl
|
|
# /var/run/ppp/vpn-in'' and do a ``show links'', only a single link shows up.
|
|
# If you connect to the vpn diagnostic socket (which is created in
|
|
# ppp.linkup.span-isp.working, you see three links. This is because inetd
|
|
# is told to ``wait'' for ppp to finish and the receiving ppp gets to
|
|
# handle all incoming packets on the first descriptor.
|
|
#
|
|
# This is why enabling LQR won't work - VPN-IN has magic number problems,
|
|
# fails to reply to LQRs and the VPN invocations end up shutting down.
|
|
#
|
|
# If anyone can come up with a better way of doing PPP over UDP I'd be
|
|
# interrested to hear it. Currently, the server doesn't connect() or
|
|
# bind().... but the client connect()s. Is there any other way ?
