Opened this issue · 11 comments

On my Froyo (visible with many custom roms) I saw the issue that the detection
of the running vpnc PID did not work.
Attached mini patch seems to solve it for me.
Thanks for your good work.

I can confirm this Issue on "Leedroid 2.1" (FroYo Rom). I get "Failed to
connect" though it connects just fine to the vpn (with "ip rul del table wifi").
If i go to console i get no output on "ps | grep 'vpnc$'" but i get output for
"ps | grep '[v]pnc --script'".
How can i use this patch? I have no idea how to compile it.

Managed to change apk in the meantime. I know now where the Issues lies. It
depends on the BusyBox Version. They changed "ps" in 1.17
For Busybox version < 1.17 "ps | grep 'vpnc$'" works
For Busybox Version >= 1.17 "ps | grep '[v]pnc --script"
A Busybox Version check should be integrated in "get-a-robot-vpnc". But it
looks like the devs aren't really active atm. I managed to apply the above
patch but i can't code and have no idea how to rewrite the code to check
busybox version.
An alternative to a busybox check would be to use both commands to check if the
vpnc process is running. This shouldn't be hard to code. Something like that:
if "ps | grep 'vpnc$'" has no output
then
if "ps | grep '[v]pnc --script'" no output
then not connected
else -> connected
else -> connected
This should really be implemented since there are ROMs out there that don't use
the outdated busybox 1.16....

Can somebody compile v0.99 with this patch applied, please ?
I'm using Leedroid 2.2 f and didn't manage to do so.
The Target-Network is an open Wifi, but one has to connect to the VPN to have
Internet-access.
The default v0.99 says it can't connect. The following Version connects, but I
can't surf the internet.

As per request a working .apk with my little patches. Tested with LeeDroid 2.2f:
- needs busybox 1.17.x
- tun.ko loaded or available in /lib/modules/tun.ko or
/system/lib/modules/tun.ko

I'm using get-a-robot-vpn-frontend.apk from nikolas.pooch, Nov 27, 2010 and
connection to Cisco is OK, but I cannot disconnect using the frontend.
Disconect can be done only by disable Wifi/GPRS. I have HTC Desire with
Leedroid 2.3d (i've tested 2.3a,b,c with same trouble). Blue LED is still
ligh-on }can be switche off by command in terminal). Busybox in Leedroid is
1.18.1.

Lee made a custom busybox when 2.3 came out (i told him on xda thats not a nice
idea because it may cause issues with apps that use it). Since the apk uses
busybox to "kill" vpnc im pretty sure the issue lies there.
You can try to install busybox 1.72.2. It should work with that version.

Thank's for your advice. Do I have to do S-OFF on my phone to get another
version of busybox then installed in Leedroid 2.3d? I have only rooted phone.
Thanks for answer.

Using the patched version linked above removes the PID failure of the 'stock'
.99, but I'm getting a different error below and it fails to work. Any help
appreciated.

I got problems with this version too.
If anyone still have issues. here's what worked for me:
VPNC-debug.apk from this thread:
http://code.google.com/p/get-a-robot-vpnc/issues/detail?id=38
and slightly modified vpnc-script

I have problems running vpnc on SAMSUNG Galaxy tab. Here is how I fixed them.
By default busybox is installed in /system/xbin. More of the tools used in
vpnc-script as awk, sed, ip, ifconfig, route... are suppose to use versions
provided by busybox. In addition the stock android system provides a "toolbox"
which is located in /system/bin. Some of the tools are available in both
binaries and because the $PATH variable is "/system/bin/:/system/xbin" I
changed the vpnc-script:
--- vpnc-script 2010-06-12 13:08:30.000000000 +0300
+++ vpnc-script_v099.vilkata 2011-03-22 10:01:29.000000000 +0200

-PATH=/sbin:/usr/sbin:$PATH
+PATH=/system/xbin/:/sbin:/usr/sbin:$PATH

I managed to fix "no PID detection" issue with using stock "ps" command from
/system/bin/toolsbox instead /system/xbin/busybox by just removing ps
association to busybox:
adb shell
$ su
# busybox mount -o rw,remount /system
# rm /system/xbin/ps
Verify that there is /system/bin/ps tool available, and if not create the link
# cd /system/bin
# ln -s toolbox ps
Finally for the DNS issue I used this:
