openwrt以太坊
1. 软路由装OPENWRT可以支持链路聚合，汇聚么
端口就是在传输较大码率数据时，使用多条链路均摊。如果连接到磁盘阵列的数据传输速率为4Gbps，连接的交换机最大为千兆口，可以使用8个交换机的物理端口聚合，形成一条逻辑链路，每个端口速率为500Mbps。端口汇聚就是有10条以太网线要求接入，但是实际就有一个物理接口，可以使用交换机，将10个以太网接口数据汇聚到一条以太网链路上。
2. 极贰openwrt 编译 7620a+7621e，能够开启 2.4G，5G 该怎么打开
1. 下载openwrt最新代码
2. 下载openwrt官方的7621e驱动https://github.com/openwrt/mtk-wifi-gpl
3. 参考https://code.google.com/p/openwrt-hiwifi/, 打上hc5761的补丁，使用其hc5761的config，并开启mtk-wifi-gpl
4. 编译完成通过ttl，sysupgrade -F -n openwrt-ramips-mt7620a-hiwifi-hc5761-squashfs-sysupgrade.bin刷机
5. 完成重启，2.4G能够开启

3. openwrt 在网卡eth0.2上获取IP失败! ,认证成功但无法上网
获取IP失败，你还能认证成功，碉堡了。在你的电脑IPV4设置里把DNS自动获取改成手动获取，然后把DNS填进去试试。
4. openwrt如何转wifi为有线信号
啥配置文件都不用改好么?刷最新版的openwrt上去,然后进luci里面,找到接口-无线-搜索到你的无线网,然后输入密钥点加入,保存并应用就好了么.....
5. 入接口选择vlan 10 出接口选择上联口eth1
先看看网络拓扑，MW305R+刷OP，单口上联ROS。设置两个SSID，一个是无VLAN，一个VLAN ID 200
下面是OP的网络配置：
config interface 'lan'
option type 'bridge'
option _orig_ifname 'eth0 radio0.network1'
option _orig_bridge 'true'
option proto 'none'
option delegate '0'
option ifname 'eth0'
config interface 'wan'
option ifname 'eth1'
option proto 'dhcp'
option delegate '0'
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'switch0'
option vlan '1'
option ports '0 1 2 3 4'
config switch_vlan
option device 'switch0'
option vlan '2'
option vid '200'
option ports '0t 1t'
config interface 'VLan_200'
option type 'bridge'
option proto 'none'
option ifname 'eth0.200'
option delegate '0'
无线部分配置：
config wifi-device 'radio0'
option type 'mac80211'
option hwmode '11g'
option path 'platform/qca953x_wmac'
option htmode 'HT20'
option channel 'auto'
option txpower '12'
option country 'US'
config wifi-iface
option device 'radio0'
option mode 'ap'
option encryption 'none'
option ssid 'OpenWrt_Lan'
option network 'lan'
option isolate '1'
config wifi-iface
option device 'radio0'
option mode 'ap'
option encryption 'none'
option ssid 'OpenWrt_200'
option network 'VLan_200'
option isolate '1'
这样设置后，无VLan的接口会失效，不能从ROS获取IP。如果两个SSID都设置VLAN ID，ROS也增加对应接口，这样就没有问题。
该如何设置才能使得无VLAN的接口可以正常上联
6. openwrt怎么知道哪个商品是eth0.1，eth0.2，eth0.3
我也不知道这个问题有没有标准答案，从我的经验来讲，有这么两个办法
你把所有接口上的网线都拔了，只留一根网线插在你的网口上。这时候你在OpenWRT的命令行里跑ifconfig，看哪个NIC还有显示，那插上去的口就代表那个NIC。（注意，这个方法只适合物理接口，不适合虚拟接口）
跑ifconfig里面会有各个NIC的IP的显示，如果你能区分插在各个网口上的机器的网段，那就能区分出NIC对应的接口
需要注意的是，eth0.x很多时候都是VLan划分出来的子网（在eth0这个交换机上），所以你看到的接口可能是一模一样的（比如8口或者24口交换机），也可能是不一样的（比如家用的路由器，一般eth0.1代表Wan口，eth0.2表示lan口）。这是一个虚拟的划分概念，和实际接口的外形没有直接联系
7. 路由器能刷kali linux固件么
以发行版Ubuntu为
例（如果你在Windows下，可下载Ubuntu的ISO文件，再用wubi安装Ubuntu，可免去重新分区的麻烦），下载Buffalo
WHR-G300N V2路由器的FTP版固件文件，放到Ubuntu的/home目录下，改名rf.bin，刷入的方法如下：
1.在Ubuntu中，保证正常访问互联网软件源的情况下，找到并进入“terminal”（终端）界面；
2.输入“sudo apt-get update”按回车，根据提示输入管理员密码，开始更新软件包信息；
3.输入“sudo apt-get install tftp”，开始安装tftp软件包；
4.用牙签捅住路由器复位按钮10秒
5.拔掉路由器的电源；
6.用网线连接电脑LAN口与路由LAN口（注意不要接成蓝色的WAN口）；
7.输入“sudo service networking stop”（适用Ubuntu 9.10或以前版本）或“sudo service network-manager stop”（适用Ubuntu 10.4或以上版本）命令，以关闭系统的网络管理服务；
8.输入“ifconfig”查看是哪一个网卡与路由器相连，一般为“eth0”代号的网卡；
9.输入“sudo ifconfig eth0 192.168.11.2”，强行设定“eth0”代号的网卡的IP为192.168.11.2（因为Buffalo路由器的bootloader里的默认是IP是192.168.11.1）；
10.输入“sudo ifconfig eth0 netmask 255.255.255.0”，设置掩码；
11.输入“sudo arp -s 192.168.11.1 XX:XX:XX:XX:XX:XX”，“XX:XX:XX:XX:XX:XX”你Buffalo路由器的MAC地址，MAC地址在Buffalo路由器背面的标签上可查到，处可不输入冒号间格。
12.输入“tftp”，出现“tftp>”提示符；
13.输入“verbose”，出现“Verbose mode on.”提示；
15.输入“binary”，出现“mode set to octet.”提示；
16.输入“trace”，出现“Packet tracing on.”提示；
17.输入“rexmt 1”，每格一秒尝试一次推送；
19.输入“timeout 60”，推送尝试的时间不超过60秒；
20.输入“connect 192.168.11.1”，连接路由器（实际上并没连接，只是为连接作好准备）；
21.输入“put rf.bin”，会提示失败，并每格1秒就尝试一次推送；
22.接上路由器电源，路由器将启动，LED会亮起来，约10－20秒后，会显示开始推送以及传输进展；
23.提示推送传输完成后再等待5－10分钟，路由器的红色LED灯闪烁，然后熄灭，最后无线LED指示灯亮起，表示固件刷新成功；
24.输入“quit”退出tftp界面；
25.
输入“sudo service networking start”（适用Ubuntu 9.10或以前版本）或“sudo service
network-manager start”（适用Ubuntu 10.4或以上版本）命令，以开启系统的网络管理服务；
26.输入“exit”退出终端界面；
27.
如果rf.bin文件的来源于Buffalo官方，则路由IP是“192.168.11.1”，网卡IP必须是“192.168.11.X”才连接，用户
名为root，密码为空；如果rf.bin文件的来源于OpenWRT、Gargoyle、DD-WRT，则路由IP是“192.168.1.1”，网卡
IP必须是“192.168.1.X”才能连接，DD-WRT用户名和密码自定义，Gargoyle的默认密码是“password”。
