pty write may block, which prevents read, according to patch #502930 on
SourceForge.  Generally a lack of flow control.  We don't implement flow
control well.

Not everybody needs this in order to get the tunnel working, it depends
on the configuration of the server, and it is problematic calculating
the correct route to add.  However, the GUI PPTP client (pptpconfig)
does this automatically, and when done unnecessarily it seems harmless.

I'll take a patch that implements the same thing in C within pptp, so
that people who don't use the GUI get it done for them.

Here's what the pptpconfig.php program does;

- the IP address of the PPTP server is obtained from the name, using
  gethostbyname(),

- the command "ip route get $ip | head -1" is executed, where $ip is the
  IP address determined above, and the result of the command is stored;
  it is a route specification of the path to the server before the
  tunnel is started,

- in routing_start(), an "ip route add" command is done using the route
  specification obtained above,

- when the tunnel is shutdown, an "ip route del" command is done using
  the same route specification.

I would prefer that the patch implements this by embedding the
equivalent syscalls within the pptp program, rather than use system() or
popen() to execute the /usr/sbin/ip program.

I would also prefer that there be a command line option for disabling
the feature.

- call manager is not being reused as it was designed to be; if a
tunnel is started within a minute of a tunnel being stopped, it does
not succeed; symptom is LCP ConfReq's without any traffic from the
server.

- pptp.8 update man page for new options
- pptp.c long_options array should use NULL for second last arg, not 0
- pptp.c use getopt_long more simply, e.g. set flags in option array

  being logged.

- clean up -T errors in pptp-command,

23rd December 2000

Things to do:
  Autoconf/automake this beastie.
  Fix do_gre_copy semantics to properly handle multiple calls.
   Like the call manager, there should only be one gre-copy process
   per connection.  This process needs to funnel packets to different
   output tty's, though, depending on the call-id embedded in the
   GRE encapsulation.  pptp.c must then be modified to use an
   already-existing gre-copy process in the same way it uses an
   already-existing call manager.
