get free internet access by openvpn

previously, we are talking about how to tune up openvpn configuration, now we are talking about how to get free internet access by openvpn.

as you know that openvpn can run on TCP or UDP mode, on this section, we will try to use TCP connection.

for years ago, people use ssh tunnel over http inject technique to make socket connection, then they direct firefox to their new tunnel. You still need to set all application to use this socket connection to go out. Or set it with proxify.

well, openvpn can do it easily, you just need NMDVPN client, then set your openvpn configuration file to be use TCP, and add some operator bugs there. Just see here :

then wait until the application success to make new routing to your vpn server : 

by this way,

• you not only speed up your internet connection but also break your internet quota, however you will get FREE internet access. (even you are on ZERO balance). 
• all application will run properly, because you will get full tcp/ip stack, no need to proxify it.
• its very easy to use.

speed up open vpn

today, i will share my experience to speed up vpn connection over mobile internet broadband. Officially i just get 512 kbps, but we can speed up up to 14 Mbps then. its depend on signal strenght in your location.

well, lets start by setup server configuration. As you know that openvpn server can be use as certificate (tls), password only, tls +  password, and static key. whatever you chose it, what you need to tune up are

proto [udp/tcp]
reneg-sec [604800/ make it bigger]
sndbuf [100000 / make it bigger]
rcvbuf [100000 / make it bigger]
tun-mtu [48000 / make it same with server]
fragment [0 / let it 0]
mssfix [0 / let it 0]

if you want to run openvpn over socket tunnel such as ssh tunnel, maybe you can set 

cipher none
auth none

because you are on secure connection now, already encrypted by ssh.

remember, if you make tun-mtu bigger, you should also tune up the link-mtu bigger too.

install 1k3 ubuntu 13.10

sudo apt-get install ndiswrapper-common ndiswrapper-utils-1.9

1. plug in your modem and check it

2. create file :  /etc/usb_modeswitch.d/0408:ea25 the content as below :

DefaultVendor= 0x0408

DefaultProduct= 0xea25

TargetVendor= 0x0408

TargetProduct= 0xea26

MessageContent="5553424312345678000000000000061b004600000000000000000000000000"

CheckSuccess=20

3. add this command to  /lib/udev/rules.d/40-usb_modeswitch.rules

# LTE Modem 1k3m

ATTRS{idVendor}=="0408", ATTRS{idProduct}=="ea25", RUN+="usb_modeswitch '%b/%k'"

4. add this command to   /etc/modprobe.d/mobily-lte.conf 

options usbserial vendor=0x0408 product=0xea26

5. restart the services 

sudo ser­vice udev restart

sudo rmmod option 

sudo rmmod usb_wwan
sudo rmmod usbserial
sudo modprobe usbserial
sudo modprobe usb_wwan
sudo modprobe option 

6. unplug the modem, then plug it again, and check with dmesg, you should see as below :

7. create your dial-up profile on network connection menu, or you can use wvdial

note : 

1. for band selection, you can choose on your profile, you may use LTE only or 3G only, or others as well.

2. light indicator color : 

• violet : its ready to use, but its not LTE
• blue : its LTE ready
• red : your modem in trouble

3. forcing to LTE service with wvdial, according to  http://www.eigenmagic.com/2012/03/14/how-to-get-telstra-4g-mobile-broadband-working-with-linux/
you should use AT+ZSNT=6,0,0 to force on LTE

how to hide ip

sometimes, you need to hide your real ip address for some reason. let say :  you want to download some file from korean server, while the server just allow traffic from korean. There are some technique to make it, today we'll learn about how to hide your real ip and location using proxying or serial proxy.
