[vpnc-devel] VPNC Front End

Mon Mar 2 22:12:11 CET 2009

hi joshua,

   I built my vpnc to run on Vista/X64 and your front-end GUI worked out great
   if you can support 2-phase authentication... I was using vpnc release 0.5.3 +
   Tilman Schroder's Vista Patch. (the one fixed the routing table using 0.0.0.0 routes).

   Using your vpnc front-end, i got prompted (a pop-up) dialog for the 1st challenge
   but i didn't get another prompted dialog for the 2nd challenge . . Is that somewhere you
  can modify your GUI to allow users to define 1-phase or 2-phase challenge...

   Here is my vpnc connection output with 2-phase authentication:

What are the specific Vista and x64 fixes? You may not need them, vpnc works fine on Vista. 

The cygwin DLL is modified to use an alternate registry location, the front end relies on this registry location to function, you would then need to ensure those registry keys exist. Probably more work than it is worth. You should be able to just drop your vpnc.exe in the same directory, assuming you aren't linked against any further DLLs. I do not use the jscript file, I have implemented its functionality in an AutoIt script which has been compiled into an exe. I'm not a big fan of jscript.

What does the output of vpnc look like during this two phase challenge? It should be easy to implement.

joshua, i downloaded your vpnc front-end and tested a bit on my Vista system.
i have few questions about how to use your vpnc front-end to work with the
my own copy of vpnc. This is my custom built vpnc with some Vista/x64 fixes.

I noticed from your tarball, the bin directory has  your copy of vpnc.exe and sh.exe
along with your other *.dll files. If i want to use my own compiled vpnc.exe
and vpnc-script-win.js is that all i need to do is to replace those files with my own ??

Also my authentication requires 2-phase challenges..i.e. i need to provide 2 auth-challenges
in sequence... While your GUI front-end only prompts for the first challenge but didn't
prompts again when the 2nd challenge was requested by my Cisco vpn server... 
(i have Xauth Interactive set in my default.conf to have it working when doing command
line connection). Is this something you can modify to address this 2-phase auth-challenge ??

thanks...

wayne chan

I created an open source VPNC Front End for Windows, it is currently hosted on Sourceforge. I'm sending an email to this list because I want to make sure I'm not stepping on any toes. I have not modified any of the vpnc sources, they are just compiled with cygwin. I am providing in an installer the required cygwin libraries:

cyggcrypt-11.dll
cyggpg-error-0.dll
cygiconv-2.dll
cygintl-8.dll
cygwin1.dll

I modified the source of cygwin so I do not interfere with other cygwin applications. It will load in an entirely separate memory space and it uses an alternate registry location.

I also provide the TAP drivers provided by OpenVPN.

I'm in the process of setting up the Sourceforge site below, but the main sources and the installer are there.

I know there are probably quite a few people out there looking for something like this.
