MT7601u-AP模式（hi3518e）

1 mt7601u-ap模式源码编译

2、把src/os/linux/下的所有的ko文件拷贝到开发板，其中有三个ko文件

    mt7601Uap.ko     rtnet7601Uap.ko   rtutil7601Uap.ko

2.1、把源码下etc/Wireless/RT2870AP目录下配置文件全部拷贝到开发板相对应的位置

# cp RT2870AP /etc/Wireless/RT2870AP/RT2870AP.dat  -rf 

3、在开发板上安装ap驱动，按照顺序来安装,因为三者有依赖关系

rtutil7601Uap.ko
mt7601Uap.ko
rtnet7601Uap.ko

4、配置wifi网卡的ip地址

ifconfig ra0 192.168.2.1 netmask 255.255.255.0

5 为了可以动态的为联入的设备分配ip地址，需要启动dhcpd服务；hi35xx只有简易的udhcpd，故搭建udhcpd服务器

5.1 创建udhcpd.leases文件

mkdir -p /var/lib/misc  
touch /var/lib/misc/udhcpd.leases

5.2 配置udhcpd.conf

# Sample udhcpd configuration file (/etc/udhcpd.conf)  
  
# The start and end of the IP lease block  
  
start   192.168.2.2     #default: 192.168.0.20  
end     192.168.2.254   #default: 192.168.0.254  
  
  
# The interface that udhcpd will use  
  
interface   ra0     #default: eth0  
  
  
# The maximim number of leases (includes addressesd reserved  
# by OFFER's, DECLINE's, and ARP conficts  
  
#max_leases 254     #default: 254  
  
  
# If remaining is true (default), udhcpd will store the time  
# remaining for each lease in the udhcpd leases file. This is  
# for embedded systems that cannot keep time between reboots.  
# If you set remaining to no, the absolute time that the lease  
# expires at will be stored in the dhcpd.leases file.  
  
#remaining  yes     #default: yes  
  
  
# The time period at which udhcpd will write out a dhcpd.leases  
# file. If this is 0, udhcpd will never automatically write a  
# lease file. (specified in seconds)  
  
#auto_time  7200        #default: 7200 (2 hours)  
  
  
# The amount of time that an IP will be reserved (leased) for if a  
# DHCP decline message is received (seconds).  
  
#decline_time   3600        #default: 3600 (1 hour)  
  
  
# The amount of time that an IP will be reserved (leased) for if an  
# ARP conflct occurs. (seconds  
  
#conflict_time  3600        #default: 3600 (1 hour)  
  
  
# How long an offered address is reserved (leased) in seconds  
  
#offer_time 60      #default: 60 (1 minute)  
  
# If a lease to be given is below this value, the full lease time is  
# instead used (seconds).  
  
#min_lease  60      #defult: 60  
  
  
# The location of the leases file  
  
#lease_file /var/lib/misc/udhcpd.leases #defualt: /var/lib/misc/udhcpd.leases  
  
# The location of the pid file  
#pidfile    /var/run/udhcpd.pid #default: /var/run/udhcpd.pid  
  
# Everytime udhcpd writes a leases file, the below script will be called.  
# Useful for writing the lease file to flash every few hours.  
  
#notify_file                #default: (no script)  
  
#notify_file    dumpleases  # <--- useful for debugging  
  
# The following are bootp specific options, setable by udhcpd.  
  
#siaddr     192.168.0.22        #default: 0.0.0.0  
  
#sname      zorak           #default: (none)  
  
#boot_file  /var/nfs_root       #default: (none)  
  
# The remainer of options are DHCP options and can be specifed with the  
# keyword 'opt' or 'option'. If an option can take multiple items, such  
# as the dns option, they can be listed on the same line, or multiple  
# lines. The only option with a default is 'lease'.  
  
#Examles  
opt dns 192.168.2.1  
option  subnet  255.255.255.0  
opt router  192.168.2.1  
#opt    wins    192.168.10.10

另有中文简介：

start 192.168.43.30  #定义地址池的开始地址
end 192.168.43.100   #定义地址池的结束地址
interface eth2       #dhcp服务器中响应dhcp协议的接口
opt dns 8.8.8.8 219.239.26.42   #定义dns服务器地址
option subnet 255.255.255.0
opt router 192.168.43.1     #该地址为dhcp服务器中响应dhcp协议接口的IP地址
option dns 124.207.160.106  #dns server最多可以设置3个
option domain local
option lease 86400     #租约时间，单位为秒
static_lease 00:60:08:11:ce:4e 192.168.43.100   #静态绑定mac和IP地址
static_lease 00:60:08:11:ce:38 192.168.43.110
一般情况下安装完udhcpd服务器后，会在/etc下生成其主配置文件，如果没有，可以在/etc下新建一个名为udhcpd.conf的文件

5.3 运行udhcpd

udhcpd -f /etc/udhcpd.conf &  

或者：

service udhcpd stop
service udhcpd start

6 停止udhcpd；

 ps

kill -9 [PID]
