Cisco VPN client on HTC Desire (short howto)

[Guest doktorko]

Hello guys,

I'm trying to install the tun module on desire with the following kernel

2.6.32.9-bravo-froyo-r15

I can't find the right module, so when I try:

#insmod /system/lib/modules/tun.ko

smod /system/lib/modules/tun.ko

smod: init_module '/system/lib/modules/tun.ko' failed (Exec format error)

Any suggestion?

Regards,

Daemon

For anyone that might still have problems connecting after finding a working tun.ko and a correct version of VPNC:

I had in my logcat:

D/VPN_Connections( 1672): Read vpnc process id as 1722

D/VPN_Connections( 1672): vpnc still trying to connect. Will check again in 500 milliseconds

D/Tethering( 140): tun0 is not a tetherable iface, ignoring

D/VPN_Connections( 1672): Attempt to read vpnc process id did not return anything

D/VPN_Connections( 1672): process had died, return as failed connection

But then got a workaround from this site

http://www.gossamer-threads.com/lists/vpnc/devel/1546

i.e. add "--natt-mode force-natt" to VPNC flags (press menu button in VPNC).

Hope this helps :D

same problem here, any suggestions? i tried the tun.ko from the vpnc page,

but did not help

[Guest p-d]

i have some problems with vpnc.

:

system

r8 baked with openvpn and installed VPN_Connections_v099.apk

connection to concentrator is established and i get my vpn routes:

xxx.xxx.xxx.xxx 192.168.100.254 255.255.255.255 UGH 0 0 0 eth0 <=my gateway

192.168.100.0 * 255.255.255.0 U 0 0 0 eth0

10.0.0.0 * 255.0.0.0 U 0 0 0 tun0

default 192.168.100.254 0.0.0.0 UG 0 0 0 eth0

but traceroute to 10.0.0.0 network always leads via wlan router to internet and not through tunnel interface.

what can i do?

[Guest p-d]

with aditional VPNC Flags "--natt-mode cisco-udp" the traffic seems to use tun interface but it is still not working:

ifconfig shows:

tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

inet addr:10.1.1.2 P-t-P:10.1.1.2 Mask:255.255.255.255

UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1

RX packets:0 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:500

RX bytes:0 (0.0 :huh: TX bytes:0 (0.0 ;)

why is the HWaddr 00-00...? and it is 16 byte - my windows laptop has 6 bytes HWadress:

Beschreibung. . . . . . . . . . . : Cisco Systems VPN Adapter

Physikalische Adresse . . . . . . : 00-05-9A-3C-87-00

DHCP aktiviert. . . . . . . . . . : Nein

IP-Adresse. . . . . . . . . . . . : 10.1.1.3

Subnetzmaske. . . . . . . . . . . : 255.0.0.0

Standardgateway . . . . . . . . . :

if i edit concentrator settings to "no compression" i detect only "Bytes Tx" and no "Bytes Rx"

if compression lzo is configured i can't see traffic in both directions

and subnetmask is different in windows/android

any suggestions?

[Guest p-d]

here is the solution for r8 with baked openvpn and VPN_Connections_v099.apk

Additional VPNC Flags: --natt-mode cisco-udp - if you connect to cisco device :huh:

and you need to do this: http://code.google.com/p/get-a-robot-vpnc/...s/detail?id=114

execute these commands after VPNC says "connected":

ip ru del table wifi - if you are connected via WiFi

ip ru del table gprs - if you are connected via GPRS

Hi, I've been trying this whole day to get Cisco IPsec-VPN working on my HTC Desire. But when I try to establish the connection, the application stops with the 'proces org.codeandroid.vpnc_frontend' error.

What I've done:

1) I've followed http://forum.xda-developers.com/showthread.php?t=768256 to stock 2.1

2) http://unrevoked.com/rootwiki/doku.php/pub..._driver_install and http://unrevoked.com/recovery/ to get root access

3) http://android.modaco.com/content/htc-desi...re-short-howto/ to install busybox and VPN_connections_v097.apk (with v099.apk I had the same problem)

Some more information:

Bravo PVT3 SHIP S-ON

HBOOT-0.83.0001

MICROP-051d

Touch Panel-SYNW0101

Radio-4.08.00.09

Jun 10 2010,12:12:05

and

Kernel 2.6.29-0cb9f166

What's the next step I can do to make this work?

[Guest almightybunghole]

Hi,

I've been following this thread with interest - I have an HTC Desire HD running CM6.1 RC2 - does anyone know whether this procedure will work or whether it will do something nasty?

Thanks

George
