启动过程

代码: 全选

hostapd /etc/hostapd/hostapd.conf
ifconfig wlan0 192.168.123.1 netmask 255.255.255.0 up
dhcpd -q -cf /etc/dhcp/dhcpd.conf wlan0
iptables -t nat -A POSTROUTING -o p7p1 -s 192.168.123.0/24 -j MASQUERADE
hostapd配置

# Customize these for your local configuration...
interface=wlan0

手机能连接上,我想dhcp应该没有问题,但是不知到为什么上不了网,不是手机DNS的问题(直接输入了一个ip访问不了)

不知道问题出在哪里? :em20

lxr1234 写了:nat没做
我iptables里面只加了一条 -o 输出的,刚才把 -i的也加上了,

代码: 全选

iptables -t nat -A POSTROUTING -o p7p1 -s 192.168.123.0/24 -j MASQUERADE
iptables --append FORWARD --in-interface wlan0 -j ACCEPT
还是不行,能连接上,不能上网,不是hostapd里DNS问题
很疑惑啊。NAT这里怎么设置才算正确?

把下面指令 複製 貼進終端機 執行
1. sudo sysctl -a | grep net.ipv4.conf.all.forwarding
2. sudo cat /proc/sys/net/ipv4/conf/all/forwarding
把結果直接複製 貼上來

我是在开发板上执行的,不支持sudo,结果如下:
~ # sudo sysctl -a | grep net.ipv4.conf.all.forwarding
sh: can't execute 'sudo': No such file or directory
~ # sysctl -a | grep net.ipv4.conf.all.forwarding
sysctl: error reading key 'net.ipv4.route.flush': Permission denied
net.ipv4.conf.all.forwarding = 1
sysctl: error reading key 'net.ipv6.route.flush': Permission denied
~ # cat /proc/sys/net/ipv4/conf/all/forwarding
1

可以使用 root 登入嗎
~ # sysctl -a | grep net.ipv4.conf.all.forwarding
sysctl: error reading key 'net.ipv4.route.flush': Permission denied
net.ipv4.conf.all.forwarding = 1
sysctl: error reading key 'net.ipv6.route.flush': Permission denied
可能需要 root 權限
