Monitor traffic

[Shay]

Hi

Is it possible to monitor incoming and outgoing traffic from the wireless?
(such as firewall is doing)

 

[Erel]

No. The system doesn't provide access to the raw data.

 

[Shay]

I wish to build some kind of firewall (layer 7)
Is there any to do it?

 

[Erel]

Not with Basic4android or Java.

 

[Shay]

so how?
I heard there is wireshark for andriod,
how can it be implemented here?

From the Wireshark site three days ago

While there isn't a mobile edition of Wireshark [yet], there are other packet-capture tools, based on tcpdump (which runs on most Android devices). However, tcpdump requires root privileges, so you would have to root your phone in order to use it (assuming a rootkit is available for your device).

 

[Shay]

strange - so how is it that there are firewalls for Android (or there isn't any)

 

[Shay]

anyone?

Hi

answer to your two questions

1) Firewalls in android.
they are java build frontend to set rules for iptables binary. which is the acutal firewall.

2) Wireshark or its alternative.
again native c binarry application doing the low level task there invokers being written in Java JNI to call and get then started.
