facebook 弱网测试环境基于路由器和双口ubuntu1804

需要弱网环境学习和测试
一个有俩网口的电脑
一个无线路由

facebook 的可能是唯一选择

基于linux内核的
官方
参考1
-参考3
参考2

本机dns

填入dhpcd 配置的 domain-name-server里

sudo nmcli dev show | grep IP4

得到182.168.1.33

指定网卡enp1s0的固定ip地址

ifconfig 指令指定
ifconfig 指令up 生效，一定要


root@zhangbin-i7660u:/home/zhangbin# ifconfig enp1s0 192.168.1.1 netmask 255.255.255.0
root@zhangbin-i7660u:/home/zhangbin# ifconfig enp1s0
enp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

root@zhangbin-i7660u:/home/zhangbin# ifconfig enp1s0 up
root@zhangbin-i7660u:/home/zhangbin# ifconfig enp1s0 生效了

重启dhcp服务

root@zhangbin-i7660u:/home/zhangbin# dhcpd enp1s0 -pf /var/run/dhcp-server/dhcpd.pid

dhcpd配置

配置 /etc/dhcp/dhcpd.conf

subnet 192.168.1.0 netmask 255.255.255.0 {
        range 192.168.1.110 192.168.1.233;
        option routers 192.168.1.1;
        option domain-name-servers 182.168.1.33;
}

启用
- 对enp1s0 启用dhcp 功能

root@zhangbin-i7660u:/home/zhangbin# mkdir /var/run/dhcp-server
root@zhangbin-i7660u:/home/zhangbin# touch /var/run/dhcp-server/dhcpd.pid
root@zhangbin-i7660u:/home/zhangbin# chmod 777 /var/run/dhcp-server/dhcpd.pid 
root@zhangbin-i7660u:/home/zhangbin# dhcpd enp1s0 -pf /var/run/dhcp-server/dhcpd.pid

dhcpd 成功

验证:

root@zhangbin-i7660u:/home/zhangbin# netstat -uap | grep dhcp
udp        0      0 0.0.0.0:bootps          0.0.0.0:*                           25111/dhcpd

root@zhangbin-i7660u:/home/zhangbin#

ip 转发，nat的？

root@zhangbin-i7660u:/home/zhangbin# vi /etc/sysctl.conf 
root@zhangbin-i7660u:/home/zhangbin# sysctl -p
net.ipv4.ip_forward = 1
root@zhangbin-i7660u:/home/zhangbin#

设置nat

sudo iptables -F
sudo iptables -X 
sudo iptables -t nat -A POSTROUTING -o enp3s0 -j MASQUERADE 
sudo iptables -A FORWARD -i enp3s0 -o enp1s0 -m state --state RELATED,ESTABLISHED -j ACCEPT
sudo iptables -A FORWARD -i enp1s0 -o enp3s0 -j ACCEPT
root@zhangbin-i7660u:/home/zhangbin# sudo bash -c "iptables-save > /etc/iptables.ipv4.nat"

启动内外网

enp3s0 是可上网的，dns由这个ip地址提供
enp1s0 是内网的网关，用于分配lan的ip地址的
先启动 sudo atcd --atcd-wan enp3s0 --atcd-lan enp1s0 --atcd-dont-drop-packets

要修改setings.py，加入192.168.1.1

报错

The error log is straightforward. As it suggested,You need to add 198.211.99.20 to your ALLOWED_HOSTS setting.

In your project settings.py file,set ALLOWED_HOSTS like this :

ALLOWED_HOSTS = ['198.211.99.20', 'localhost', '127.0.0.1']
