# If you connect to the vpn-in diagnostic socket with ``pppctl

|
|
|
# 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 ?
