Basically i want my Android phone to stop responding to ping requests.
I tried searching but i found no solution to this matter.
Has anyone done this? What's the easiest solution to permanently prevent the phone from responding to ping requests?
My phone is rooted and running 2.1 if that helps.
You can use iptables:
iptables -A INPUT -p icmp -j REJECT
Thanks for the reply!
This works great until i restart my phone.
What would be the best way to store this setting permanently?
I tried searching for an iptables config file but i couldn't find any.
iptables has no config file, you need run a script with all rules.
In the market you can find Autostart (root) to run a script at boot.
I downloaded Autostart and then ran the following commands:
Code:
su
mkdir /data/opt
echo "iptables -A INPUT -p icmp -j REJECT" > /data/opt/autostart.sh
Then i rebooted, pressed "Allow Always" for Autostart and rebooted once more.
Still i can ping my phone. Did i do anything wrong? Any more suggestions?
Check the rules with 'iptables -L -nv'
If nothing, try with the full path to iptables on the script (/system/xbin/iptables) and 'chmod 755 /data/opt/autostart.sh'
I just read this article,
http://blog.mycila.com/2010/06/reverse-usb-tethering-with-android-22.html
and I'm stuck on step 3. I don't have Ubuntu. How can I Bridge the 2 network interfaces?
STEP 3:
On Linux Computer, setup a bridge:
# usb0 is the new network intreface
# eth0 is the main interface connected to internet (or a gateway)
sudo ifconfig eth0 0.0.0.0
sudo ifconfig usb0 0.0.0.0
sudo brctl addbr br0
sudo brctl addif br0 eth0
sudo brctl addif br0 usb0
sudo ifconfig br0 up
sudo dhclient br0
See https://help.ubuntu.com/community/NetworkConnectionBridge to setup bridges
On windows, Bridge the 2 network interfaces

Hi all.
I'm attempting to root my phone via ZergRush's one click root. However I am on linux and i do not have a usb cable.
I downloaded the android-sdk for linux and have set up ftp/ssh on my Zte score. The problem is whenever I try to adb connect 10.10.0.25 adb does not connect with the device. I can ping my phone from my computer so it's reachable. If I try adb connect 10.10.0.25:2121 (FTP PORT) or 2222 (SSH PORT) it connect but outputs: "Device offline" and I can't run any successful commands.
I heard ssh tunneling is possible and would like to know if anybody knew the exact steps. I've tried:
# ssh [email protected] -p 2222 -R 5555:localhost:5037
and
# ssh -NR 5555:localhost:5037 [email protected] -p 2222
The latter connects through ssh but adb doesn't connect through the tunnel. The former outputs "Connection closed by remote host"
I checked the open ports on my phone and noticed 5555 isn't open so that means i must open it with setprop service.adb.tcp.port 5555 which I tried but still doesn't work. The command does go through though.
Appearantly, setprop didn't work as getprop service.adb.tcp.port 5555 outputs nothing.
Is there any way I can enable adbd to listen on my phone? I got a ssh and ftp shell up and running w/o root.
/mnt/sdcard $ getprop | grep adb
[persist.service.adb.enable]: [1]
[persist.radio.adb_log_on]: [0]
[persist.adb.trace_mask]: [1]
[init.svc.adbd]: [running]
It doesn't show service.adb.tcp.port so I can't set it. Is there a way for me to create this key? Help will be much appreciated! =)
EDIT:
Is there a way for me to chmod without root or adb? I tried chmod 777 exploit but it outputs permission denied. I'm going to see if I can change permissions some other way.
Anyone?
No luck googling for an answer.
Should I just wait and get a data usb cable?
Hi guys,
I want to use my PC running on Ubuntu 12.04 64Bit to access the internet.

Coz maybe the ones who viewed the thread didn't know a solution hence not answered
May be someone who uses Ubuntu world know...
Most of us user windows...
Sent from a Desire S waiting for Kernel 3. WAKE UP HTC!!!!
if u hv HTC sense on ur device, just tick the INTERNET PASS THROUGH option from the notification tab
and the system will do the rest
cheers
check out screenshot below
thanks for your replies
lynxnoon : yes I'v tried to do that, it will be connected to the PC but without internet connection.
ensure the adapters (esp the wired) are updated online and then try again.
Also ensure theres is pass through connection on ur fone and then try to browse with the in-built browser.
If all these still doesnt work then u have to find out if the internet service provider alllows tethering or the modem u r using.
cheers

When I connect my phone and choose internet passthrough, the phone chooses ip address in the 192.168.99.0/24. If yours creates a different subnet you will have to change below accordingly.
I hope this solves your problem.
Edit /etc/rc.local sudo nano /etc/rc.local and add the following:
echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward > /dev/null
iptables -P FORWARD ACCEPT
iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.99.0/24
iptables -A FORWARD -i eth0 -o usb0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i usb0 -o eth0 -j ACCEPT
#forward all dns queries from usb0 to google's dns server
iptables -t nat -I PREROUTING -i usb0 -p udp --dport 53 -j DNAT --to 8.8.8.8
then at terminal type:
sudo /etc/rc.local
that will get you connectivity, but it will be short lived because htc is stupid and will disconnect if it doesn't detect the winblows htc software crap.
So you will need to fake it out. Turns out the phone is listening for htc software on port 6000 for 00 02 00 00 hex.
first you have to find the ip address of your phone (if arp doesn't work or you get command not found, you probably need to sudo arp):
phoneip=$(arp -n | grep usb0 | awk 'BEGIN {FS=" "} {print $1}')
then you tell the phone that htc software is listening:
echo -n -e "\x00\x02\x00\x00" | nc $phoneip 6000 > /dev/null
To make that automagic each time us a script. Call it htcfaker or whatever:
#!/bin/bash
while :; do
phoneip=$(arp -n | grep usb0 | awk 'BEGIN {FS=" "} {print $1}')
while [ -z $phoneip ]; do
sleep 15
phoneip=$(arp -n | grep usb0 | awk 'BEGIN {FS=" "} {print $1}')
done
echo -n -e "\x00\x02\x00\x00" | nc $phoneip 6000 > /dev/null
while [ "$phoneip" != "" ]; do
sleep 15
phoneip=$(arp -n | grep usb0 | awk 'BEGIN {FS=" "} {print $1}')
done
done
Then in your startup applications, point to that script.
Hope it helps!
I'm using unrooted HTC Sensation XE and Ubuntu 12.04 64-Bits, with these scripts Internet Pass Through works beautifully!:laugh::good:

Did anyone experienced the problem that this stopped working after a day or so?
When I plug into the phone now it just wont give a ipv4 address therefore theres nothing to re-route through the pc?
Mine still working without any problem after 2 months. I can only suggest you to check 2 things:
Ensure your /etc/rc.local file is not changed due to any Ubuntu update
You have to run the "htcfaker" script in Terminal before plugging in your phone. Do not close this Terminal until you want to disconnect.

I have updated /etc/rc.local file but I'm getting below error what needs to be done? I'm newbie to Linux, neverthless tried to look into many forums but couldn't get it resolved.. Please help !!
Code:
[email protected]:~$ sudo /etc/rc.local
[sudo] password for anvyal:
iptables v1.4.18: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
Please let me know if any other info needs to be provided. Thanks in advance for your help !!

Please check the following line in your /etc/rc.local:
iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.99.0/24
You have to change the IP subnet (highlighted in red font above) to match your phone's IP address. If your phone use 192.168.1.2 for example, then you'll have to change the IP subnet to 192.168.1.0/24.
To find your phone's IP address, first connect your phone to your PC in USB Tethering mode. Then on your PC side open a Terminal and issue the command "arp" (without the quotes) which shall give you the IP address of your phone.
Good luck!:laugh:
Script update required for recent phones?
This script didn't work for me on my M8 - the Sync hex data seems to have grown, and just passing the \x00\x02\x00\x00 string caused the pass through to immediately disconnect with failure message "Either you do not have the latest version of HTC Sync Manager installed, or another phone is already using Internet pass-through on your PC".
Changing the line in the script as below fixes it:
Code:
echo -n -e "\x00\x02\x00\x00" | nc $phoneip 6000 > /dev/null
Code:
echo -n -e "\x00\x02\x00\x00\x00\x03\x00\x00\x00\x05\x00\x00" | nc $phoneip 6000 > /dev/null
I got this from vc0528.tumblr.com/post/71168788542/simulate-htc-sync-manager-via-usb-on-linux-os, which also has the alternative Perl script, which works a treat too:
Code:
#!/usr/bin/perl
use IO::Socket::INET;
#6000/tcp open X11
do{
open IN,”/proc/net/arp”; @arp=<IN>; close IN;
@d=grep ! /00:00:00:00:00:00/,grep /0x2.*usb0/,@arp;
} until($d[0]);
$_=$d[0]; s/\ .*//; chomp; print “sock:\t$_\n”;
my $sock = IO::Socket::INET->new(PeerAddr => $_ , PeerPort => 6000, Type=>SOCK_STREAM, Proto=>”tcp”) or die “Can not create socket [email protected]\n”;
print $sock “\x00\x02\x00\x00”;
print $sock “\x00\x03\x00\x00”;
print $sock “\x00\x05\x00\x00”;
close $sock;
Finally, if it helps anyone, I was wanting to set up a wifi range extender and so my IPtables was:
Code:
-A FORWARD -i wlan1 -o usb0 -m state --state RELATED,ESTABLISHED -j ACCEPT
-A FORWARD -i usb0 -o wlan1 -j ACCEPT
Hello Everyone,
I am using android 6.0 in samsung s2 plus.
I tried some app to change wifi mac address. even tried to search mac address file location but I didn't find any.
If you have any Idea How to change mac address in android 6.0 . then Help me.
Thank you in advance
Try this guide http://www.gohacking.com/spoof-mac-address-on-android-phones/
Before you spoof the MAC address, you need to record the original/current MAC address of your device which can be done according to the instruction below:
On the Home Screen of your phone, tap Menu button and go to Settings.
Tap About Device and go to Status
Now scroll down to record the 12-digit code shown under Wi-Fi Mac address. An address would read something like:
Example MAC address: E5:128:E5:69:97
Requirements for Spoofing the MAC Address
Rooted Android Phone
BusyBox app installed on your phone
Once BusyBox is installed, you need to install Terminal app
Once the above requirements are satisfied, follow the instructions below to spoof your MAC address:
Open the Terminal app and type the commands as listed below:
$ su [HIT ENTER]
$ busybox iplink show eth0 [HIT ENTER]
(This will show your current MAC address, just for your confirmation)
Now, type the following command:
$ busybox ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX [HIT ENTER]
(In the above command, replace XX:XX:XX:XX:XX:XX with your new MAC address)
You have now spoofed your MAC address successfully. To check for the change enter the following command again:
$ busybox iplink show eth0 [HIT ENTER]
(Now you should see your new MAC address)
