Hardware preparation: Mercury MW150U 150m wireless USB card (don't ask why, if you can use something else that can support ap mode and have a driver, I used Ralink and 360wifi to configure it to death)

System version: ubuntu 14.04 LTS Desktop version (new system setup root password: sudo passwd)

It is divided into two parts: configuring wifi under ubuntu and configuring ATC project

1. Configure wifi under ubuntu

1. Check to see if the wireless network card is connected: lsusb

If we display the information of our wireless network card, which means that we have identified our usb wireless network card

two。 Install hostapd and dhcp

Hostapd: the wireless network card can be switched to AP/Master mode through Hostapd, and an open (unencrypted) WEP,WPA or WPA2 wireless network can be established by modifying the configuration file.

Dhcp: simply put, ip management

Installation: apt-get install hostapd isc-dhcp-server

Verify whether the installation is successful: type hostapd and dhcpd respectively, and the detailed description of the command will be successful.

3. Configure hostapd

Vi / etc/hostapd/hostapd.conf

Hostapd.conf##

Interface=wlan0

Driver=nl80211

Ssid=autotest / / wifi name

Channel=10

Hw_mode=g

Macaaddr_acl=0

Auth_algs=3

Wpa=2

Wpa_passphrase=12345678 / / password

Wpa_key_mgmt=WPA-PSK

Wpa_pairwise=TKIP CCMP

Rsn_pariwise=TKIP CCMP

# # #

4. Run hostapd (you can skip to step 5, step 4 is to step on the pit)

Execute: hostapd-B / etc/hostapd/hostapd.conf

Error report: nl80211: Could not configure driver mode

Nl80211 driver initialization faile

Solution: nmcli nm wifi off

Rfkill unblock wlan

5. Run hostapd

Execute: nmcli nm wifi off

Rfkill unblock wlan

Killall hostapd

Hostapd-B / etc/hostapd/hostapd.conf (- B running in the background)

Or

Hostapd-d / etc/hostapd/hostapd.conf (- d runs directly)

6. Query DNS, step 7

Execution: nmcli dev list iface eth0 | grep IP4

Root@lufukeng:/# nmcli dev list iface eth0 | grep IP4

IP4.ADDRESS [1]: ip = 192.168.200.131 pick 24, gw = 192.168.200.2

IP4.DNS [1]: 192.168.200.2

IP4.DOMAIN [1]: localdomain

IP4.WINS [1]: 192.168.200.2

7. Configure dhcpd

Vi / etc/dhcp/dhcpd.conf

# # #

Subnet 192.168.0.0 netmask 255.255.255.0

{

Range 192.168.0.2 192.168.0.10

Option routers 192.168.0.1

Option domain-name-servers 192.168.200.2 the DNS of the query, there is no need to change it.

}

# # #

8. Set up wlan0

Ifconfig wlan0 192.168.0.1 netmask 255.255.255.0

9. Start dhcp-server

Touch / var/run/dhcp-server/dhcpd.pid

Chmod 777 / var/run/dhcp-server/dhcpd.pid

Dhcpd wlan0-pf / var/run/dhcp-server/dhcpd.pid

10.IP forwarding

Bash-c "echo 1 > / proc/sys/net/ipv4/ip_forward"

11. Set up NAT

Iptables-t nat-A POSTROUTING-o eth0-j MASQUERADE

Here, if the phone is connected to wifi and surf the Internet normally, it will be successful.

Download and configure ATC

1. Install pip

Terminal input: sudo apt-get install python-pip

Install the django components required by ATC through pip:

Pip install atc_thrift atcd django-atc-api django-atc-demo-ui django-atc-profile-storage

two。 Create a django project to use the ATC server app

Django-admin startproject atcui

3. Modify ATC configuration

Cd atcui/atcui

Vi settings.py

Add the following to INSTALLED_APPS

'rest_framework'

'atc_api'

'bootstrap_themes'

'django_static_jquery'

'atc_demo_ui'

'atc_profile_storage'

Vi urls.py

Change the urlpatterns content to the following:

From django.views.generic.base import RedirectView

From django.conf.urls import include

Urlpatterns = [

Url (r'^ admin/',admin.site.urls)

Url (r'^ api/v1/',include ('atc_api.urls'))

Url (r'^ ATC _ demo_ui/',include ('atc_demo_ui.urls'))

Url (r'^ api/v1/profiles/',include ('atc_profile_storage.urls'))

Url (r'^ $', RedirectView.as_view (url='/atc_demo_ui/', permanent=False))

]

Cd atcui / / change to the directory where manage.py is located

Update django database: python manage.py migrate

4. After the configuration is completed, it can be run. Here, the network card eth0 is used as the public network connection, and wlan0 is used as the private network connection, which is specified by parameters when starting.

Sudo atcd--atcd-wan eth0-- atcd-lan wlan0

5. Run ATC UI

Python manage.py runserver 0.0.0.0:8000

When you visit 192.168.0.1 profile 8000 through a mobile browser, you will display a web page that has not been configured with any Facebook. The file configuration that has been configured is provided below.

6.facebook has configured common network configurations for us in its own project, which can be added in the following ways

Apt-get install git

Git clone https://github.com/facebook/augmented-traffic-control.git

Apt-get install curl

Cd augmented-traffic-control

Utils/restore-profiles.sh localhost:8000

7.ATC usage

Turn on / / Open

Select / / Select

Update Shaping / / Update. After selecting the network, click Update.

Turn off / / close

Finally, a copy of the network parameter configuration is attached (for reference only):

Network bandwidth (bandwidth)

Delay (latency)

Packet loss rate (packet loss)

Packet error rate (corrupted packets)

Disorder rate (packets ordering)

Name Latency Bandwidth Packet-loss

GPRS (good) 500 50 2

EDGE (good) 300 250 1.5

3G/HSDPA (good) 250 750 1.5

DIAL-UP (good) 185 40 2

DSL (poor) 70 2000 2
