I have provided above of the log of what happen on my adroid mobile.
Actually the log says, initialization complete which means that the is no error on the configuration file and the authorization to connect client to server.
however, the problem is,
TUN/TAP device tun0 opened <<-- here tun/tap device tun0 is opened but did after that entry
you cannot see that there is no this one
Sun Mar 31 08:12:48 2013 MANAGEMENT: >STATE:1364688768,ASSIGN_IP,,50.8.0.2,
Sun Mar 31 08:12:48 2013 /system/xbin/bb/ifconfig tun0 50.8.0.2 netmask 255.255.240.0 mtu 1500 broadcast 50.8.15.255
which means it did not set ip address for the tun0 device which I dont know why.
I have tested this same configuration on galaxy y and galaxy y duos both with preload tun/tap driver
but only galaxy y it work and not on galaxy y duos. what could be the problem?
I have installed identical packages/software on the 2 mobiles with same install procedure.
