9 Not everybody needs this in order to get the tunnel working, it depends
10 on the configuration of the server, and it is problematic calculating
11 the correct route to add. However, the GUI PPTP client (pptpconfig)
12 does this automatically, and when done unnecessarily it seems harmless.
14 I'll take a patch that implements the same thing in C within pptp, so
15 that people who don't use the GUI get it done for them.
17 Here's what the pptpconfig.php program does;
19 - the IP address of the PPTP server is obtained from the name, using
22 - the command "ip route get $ip | head -1" is executed, where $ip is the
23 IP address determined above, and the result of the command is stored;
24 it is a route specification of the path to the server before the
27 - in routing_start(), an "ip route add" command is done using the route
28 specification obtained above,
30 - when the tunnel is shutdown, an "ip route del" command is done using
31 the same route specification.
33 I would prefer that the patch implements this by embedding the
34 equivalent syscalls within the pptp program, rather than use system() or
35 popen() to execute the /usr/sbin/ip program.
37 I would also prefer that there be a command line option for disabling
44 - call manager is not being reused as it was designed to be; if a
45 tunnel is started within a minute of a tunnel being stopped, it does
46 not succeed; symptom is LCP ConfReq's without any traffic from the
51 - finish --max-echo-wait
55 - add two configurable timeouts for echo generation and echo reply timeout,
56 requested by Tobias Brox.
58 - ship .spec with tarball.
62 - timeout connect earlier, with option to extend timeout.
66 - GRE stats to a pipe or shared memory, for GUI to use
70 - pptp.8 update man page for new options
71 - pptp.c long_options array should use NULL for second last arg, not 0
72 - pptp.c use getopt_long more simply, e.g. set flags in option array
76 - log failure of write() to raw socket, as Ryan Murray

82 - clean up -T errors in pptp-command,
87 Autoconf/automake this beastie.
88 Fix do_gre_copy semantics to properly handle multiple calls.
89 Like the call manager, there should only be one gre-copy process
90 per connection. This process needs to funnel packets to different
91 output tty's, though, depending on the call-id embedded in the
92 GRE encapsulation. pptp.c must then be modified to use an
93 already-existing gre-copy process in the same way it uses an
94 already-existing call manager.
