Make path to ifconfig and route configurable upon installation

Original post from:
http://github.com/fries/android-external-openvpn/issues#issue/2

I have a problem with OpenVPN Settings and my HTC Hero / T-Mobile G2 - i
have installed the MoDaCo custom ROM 3.2.

So Busybox is integrated, but i have no /system/xbin/bb/ifconfig - if i ask
'which ifconfig' i get /system/xbin/ifconfig (which links to busybox)

if i want to start my openvpn config, after entering the password i get
this error:
FATAL: Linux ifconfig failed: could not execute external program

Can you fix this for the MoDaCo Hero users? :)

Let me know if i can help you in any way!

thank you for this release!

so in the OpenVPN Settings it is "Connected to [IP] as" - that worked now! :)

but still it looks lik i'm not in the VPN - the up: and down: values are not 
changing
when i make some traffic with f.e. the browser or the youtube app (up: 0.02kBps 
-
down: 0.02 kBps).

when i do a ifconfig on the console of my hero i get the following devices, with
openvpn running and without:
lo, rmnet0

so there is no tun0 - but there should be, right?

so i restarted my phone, made an 
 lsmod
 "tun 11172 0 - Live 0xbf000000"

then i tried to:
 su
 ifconfig tun0 up
 "ifconfig: SIOCGIFFLAGS: No such device"

so OpenVPN Settings shows me a valid IP where it is connected, but the traffice 
is
not going thought the VPN. Whats the problem with my HTC Hero? :)

First we should make sure the vpn connection is established and the interface is
configured correctly. Could you please start openvpn from the commandline and 
see if
there are any errors when it configures the interface? Then try to ping your 
peer. If
this works the interface should be configured correctly (You should also see the
up/down counters changing while pinging). You may also check the configuration 
using
ifconfig. But make sure you are using ifconfig from busybox, by using the full 
path.

No traffic will be redirected through the tunnel. This only happens if you use 
the
redirect-gateway option in your openvpn config, which I have not tested so far.

Ah, I remember. Android libc (bionic) does not support the getpass function 
which
openvpn seems to use when asking for the passphrase. When I ported openvpn I 
created
a stub just returning the empty string. (It's defined here: 
http://github.com/fries/android-external-openvpn/blob/master/missing.c). That's 
the
reason you where not asked for a passphrase. 

OpenVPN-Settings will advice openvpn to ask for a passphrases via the management
interface.

thank you for the detailed explanation!

so actually i can't test if openvpn on console is working, right?

Original comment by stefan.l...@gmail.com on 19 Mar 2010 at 10:02

GoogleCodeExporter commented 8 years ago

Actually you could use the '--askpass [file]' option. This would read the 
passphrase
from a file. This should be good enough for testing.

Hmm, could you post your config?
The command line seems to be correct. But I would first cd into 
/sdcard/openvpn/ and
then call 'openvpn --askpass /sdcard/pw --dev tun0 user.conf'. You might also 
add
--verb 4 or --verb 5 to get more verbose debugging output.

Here's my problem, the 2.1.1 version is having some problem with ifconfig.  
However
ifconfig is located in these places:

./system/bin/ifconfig
./system/xbin/bb/ifconfig
./system/xbin/ifconfig

and 'which ifconfig' shows:  /system/xbin/ifconfig

Here's the log showing the error.  Any ideas?  I'm running DroidMod 1.0 on a 
Motorola
Droid.  OpenVPN 2.1_rc15 which comes installed with the rom works just fine.

i'm now running N1 FroYo with cyanogen rooter, which gives root and busybox

My server config works with about a dozen Win/OSX/Linux clients.

The client config I am using worked with 5.0.6 (built-in openvpn binary) + 
OpenVPN Settings (couldn't get the 
"redirect-gateway def1" to work using 5.0.6 built-in openvpn gui).

# which ifconfig
/system/bin/ifconfig

# find / -name ifconfig
/system/xbin/ifconfig
/system/bin/ifconfig

I know that the BusyBox ifconfig is in /system/xbin/ifconfig so I used this 
location during OpenVPN-Installer 
binary installation.

I get this, as su:

So then I check if the interface is up:
# /system/xbin/ifconfig
eth0 (details omitted)
lo (details omitted)

No TUN interface seems to be up, no IP addresses assigned (from 
OpenVPN-Settings).

So then I do this (just like my desktop client does):

#/system/xbin/ifconfig tun0 delete
#/system/xbin/ifconfig tun0 10.8.0.6 10.8.0.5 mtu 1500 netmask 255.255.255.255 
up

OK, tun0 shows up:
tun0      Link encap:UNSPEC  HWaddr

          RX bytes:1456 (1.4 KiB)  TX bytes:0 (0.0 B)

I can ping 10.8.0.5
I can not ping 10.8.0.6 (not a problem, I can't ping it from the desktop 
either).

I can not ping the server 10.8.0.1

Why not? No route? Duh.
# /system/xbin/route

default         tomato          0.0.0.0         UG    0      0        0 eth0

In summary, I am inclined to conclude that neither ifconfig nor route location 
hard-coding has the desired 
effect :(

I am willing to troubleshoot this till no tomorrow as I NEED to be able to 
openvpn.

I noticed that, p-t-p ip assignment to tun0 is actually wrong...

                    ^^^^^^^^        ^^^^^^^^

actually the first one should read 10.0.0.6.

I am guessing that should be the problem.

By the way, is ifconfig and route ripped off from this openvpn binary?

Problem solved....

This binary doesn't work with busybox:

However this does:

By the way there should be pointtopoint in between the ips for the ifconfig 
problem...

Both links cited in #17 use /system/xbin/bb/ifconfig and /system/xbin/bb/route.

The difference is that openvpn-static.bz2 contains OpenVPN 2.1_rc15 whereas 
openvpn-static-2.1.1.bz2 contains OpenVPN 2.1.1.

get pushed.

FYI, I know it is a horrible, horrible hack, but I at least got to the point 
now where I am getting an internal IP address.  Next step is to figure out the 
proper routes.

how I did it:
0. I also have Froyo FRF91 on Nexus1 + root + busybox (from MoDaCo).
1. I had to use the statically linked openvpn listed above 
(http://github.com/downloads/fries/android-external-openvpn/openvpn-static.bz2)
2. Unzip and copy openvpn-static-2.1.1 to files to device. (I renamed mine 
/system/xbin/openvpn)
(for those who don't know how to copy, use adb remount, then adb shell <insert 
command here> to get around the "read only file system")
3. Make folder /system/xbin/bb
  Example: adb remount; adb shell mkdir /system/xbin/bb
4. Make symbolic links to ifconfig and route
  Example: adb shell ln -s /system/xbin/ifconfig /system/xbin/bb/ifconfig
           adb shell ln -s /system/xbin/route /system/xbin/bb/route

//Now I'm stuck at not being able to ping anybody (including google)
sh-3.2# ping INTERNAL.SITE
PING INTERNAL.SITE (XXX.XXX.XXX.XXX) 56(84) bytes of data.

OK, work around tested and works!! I can now tunnel all my traffic to inside 
and outside networks.

This has been tested using TAP.  Your mileage may vary.

Problem: route added to internet IP address of my vpn server.
Solution: delete route after routing has occured.

Implementation:
1.  Create a simple script to delete router.  Example (/sdcard/openvpn/up.sh)

#!/system/bin/sh
/system/xbin/route del YOUR_VPN_INTERNET_IPADDRESS

2. Make the file executable.  chmod +x /sdcard/openvpn/up.sh
3.  Modify your openvpn.conf to call script after routing, or pass it in as a 
command line argument.  I did the modification to script file.
     route-up "/system/bin/sh /sdcard/openvpn/up.sh"

How do you get your client (N1) to come up with a route, so as to have traffic 
routing through the server?

Let me summarize that IFCONFIG/ROUTE location hardcoding during installation of 
openvpn-installer DOES NOT WORK (at least not to /system/xbin)!!!

To get openvpn-installer to work as expected, one needs to:
-install openvpn-installer
-during installation point to busybox (ifconfig/route) at /system/xbin/bb
-create the symbolic links in those locations as per post 30

After this everything (openvpn-settings) works as expected (if configured 
properly ;) )!!

Followed posts 30 & 34 - not working on fully rooted Evo 4G 1.47.651.1.

Connects but External IP & Ext. Hostname are still issued by isp, not vpn 
provider.

Same .conf working on pc.

I have the same problem with #12, finally got it solved by using the method 
provided by #30.
I just installed OpenVPN Installer and OpenVPN Settings from Android Market, 
and excuted the commands in #30, finally got it done.
If all the files and operations are correct, follow #30 has no problem.
My phone is HTC G3 Hero, ROM is 3.2-update-hero-modacocustomrom-core-signed.zip

I have no more idea so I hope to get help here.
Installation is ok.
VPN connects and a ping to google.com works but I can t ping internal (e.g. 
192.168.1.30) IPs.

This is the Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

Number 34 solved my problem. I wasn't received an ip address, and no tun0 
interface was being created, and no routes were being added. 

All I needed to do was:

1.Point the openvpn installer to the /system/xbin/bb directory for ifconfig
2. Create /system/xbin/bb
3. Create links in /system/xbin/bb that point to /system/xbin

I don't really understand what the difference is between having it use links 
and using the path, but I'm happy it's working. Turnkey would be nice, but 
free's nicer. :)

For the traffic routing issue, if you do this
# ip ru show
0:  from all lookup local 
3001:   from all lookup wifi 
32766:  from all lookup main 
32767:  from all lookup default 
you have a few tables.

connect to your vpn network

ping <an internal vpn ip> -- if that works then great, but i doubt it would
ping -I tun0 <an internal vpn ip> -- If this works then that means that your 
traffic isn't being routed through the tunnel tun0

If you're on wifi connecting through vpn try this:
ip ru del wifi
then ping <an internal vpn ip> -- that worked for me

If you're on gprs then: ip ru del gprs.

I'm still trying to find out how to make the route work without having to do 
that though.

Is this application being monitored and updated? Openvpn is now 2.3 but the 
installer is still using 2.1.1 which is still having the ifconfig/route issue. 
I hope there will be a permanent fix rather that work around.

i don't expect a permanent fix.

your best bet is to install cyanogenmod which has openvpn built-in

Nexus One MIUI ROM v1.1.7
Had to do the same as #34 and #43. Even if in route and ifconfig in 
/system/xbin are links to busibox, the openvpn installed by openvpn installer 
only works if one creates /system/xbin/bb and links /system/xbin/route and 
/system/xbin/ifconfig there.

@friedrich
please can you change it and update it on market ?
maybe you can change the settings , that the path to route and ifconfig is 
always /system/xbin (there are the apps be sure..) and cahnge the code, so that 
route and ifconfig use always the /system/xbin/ path, then it would be ok, and 
noone must create apath manually ... for newbies it would be easier to know .. 
this::

only to be sure - here in summary:
it works if it will be done in this way:

1.) install binaries to /system/xbin
2.) select path to ifconfig and route -> /system/xbin/bb
3.) make a link to xbin -> "ln -s /system/xbin /system/xbin/bb"

then it works fine :)
