Android平台网络常用命令

Android平台网络常用命令

工作中经常用到的一些命令，整理一下，方便以后进行参考
1.IP设置
 ifconfig eth0 128.224.156.81 up  //一般的嵌入式linux中设置IP。

ifconfig eth0 128.224.156.81 netmask 255.255.255.0 up

netcfg eth0 up dhcp   //通过dhcp 自动获取ip，网关，掩码等。

2. gateway

route add default gw 128.224.156.1  //一般的嵌入式linux会用这个命令添加网关,但是android中不用。直接“netcfg eth0 up dhcp” 自动分配IP等。

3. dns:

echo "nameserver 128.224.160.11" > resolv.conf  //一般嵌入式linux中设置dns的方法

nameserver 128.224.160.11

setprop net.dns1 128.224.160.11   //android中设置DNS的命令。

setprop net.dns2 147.11.100.30
4、自动获取IP
# ./dhcpcd -U eth1

broadcast_address='192.168.100.255'

dhcp_lease_time='30'

dhcp_message_type='5'

dhcp_server_identifier='192.168.100.1'

ip_address='192.168.100.10'

network_number='192.168.100.0'

routers='192.168.100.1'

subnet_cidr='24'

subnet_mask='255.255.255.0'
 
5、自动获取IP的详细调用过程
# ./dhcpcd -h eth1 -d
