Unable to connect: assertion failed

[henrik242]

I'm on the latest version (0.6.6), and I'm getting an error as the client connects:

# ./run
WIFI: driver loaded
WIFI: wpa_supplicant started
WIFI: wpa_supplicant connected
WIFI: OK wlan0 58:17:0c:4a:xx:xx

DHCP: ACK 58:b0:35:7b:xx:xx 192.168.5.101 hnrk
assertion "IdIn(IPFlowId(b).reverse()) == in()" failed: file "/home/szym/workspace/barnacle/jni/../native/nat/natopen.hh", line 98, function "void MappingFullCone::applyOut(const IPFlowId&, Buffer&)"
[2]   Segmentation fault      ./nat

The link seems fine, but I'm unable to send and receive data. I'm using a Sony Ericsson X10 mini pro with Android 2.1-update1.

This is pretty bad. Could you enable NAT debugging under Settings > NAT > Debug. Then when you get the error, could you run "adb logcat" and send me the dump? Thanks!

Sure, here you go:

[szym]

I'm looking into this issue. I am unable to reproduce this error, so right now I'm trying to figure out what could lead to this assertion failing.

[rwickst]

I am getting the same error. My technology level in this area is very low.

I am able to create a VPN connection to the client site; however, when I try to connect to the server via a Remote Desktop icon on my computer I receive the above error and shuts down my internet connection.

When I use EasyTether with a USB cable, I am able to connect to the server using the Remote Desktop icon on my computer.

I wouldl prefer to use Barnacle's wirelessly tethering instead of using a USB cable.

Thanks,
Reed

Also, I am using a Samsung Vibrant phone.

Hi, I'm running this Barnacle Wifi Tether on Xperia X10 phone, with android 2.1-update1 rooted, and I'm getting exactly the same error:
assertion "IdIn(IPFlowId(b).reverse()) == in()" failed: file "/home/szym/workspace/barnacle/jni/../native/nat/natopen.hh", line 98, funtion "voidMappingFullCone::applyOut(Const IPFlowId&, Buffer&)"

[2] Segmentation fault ./nat
Do you have any idea of what if failing?
How can I see the version that I have installed? Android report it as "Version 40"

[oliver]

Hi, this assertion failure always happens for me when I use the ICSI Netalyzr (http://netalyzr.icsi.berkeley.edu/) on laptop over Barnacle. The phone runs Android 2.1.

Hi. Has this issue ever been resolved or explained? I'm having the same problem with my motorola triumph running 2.2. I turn on barnacle tether then connect with my laptop. Then usually after 20-30 seconds, i get this error and stop receiving data.

[qorelogic]

Hi, I'm getting the same error a motorola backflip running 2.4 rooted with cyanogenmod. It happens every 17 or 57 minutes past the hour. It segfaults as soon as the clock hits (1|5)7 minutes

[Bischoff]

It segfaults immediately here, with exactly same error message as in first post.

Hardware is Xperia X8, Android 1.6, properly rooted. I have to skip the WPA phase, then the ad-hoc network is seen, but after association, the problem is with NAT. To be noticed, android-wifi-tether (another app) tells me that my kernel lacks the netfilter support and therefore cannot do NAT: maybe the problem is simple as that...
