openwrt以太坊
1. 軟路由裝OPENWRT可以支持鏈路聚合，匯聚么
埠就是在傳輸較大碼率數據時，使用多條鏈路均攤。如果連接到磁碟陣列的數據傳輸速率為4Gbps，連接的交換機最大為千兆口，可以使用8個交換機的物理埠聚合，形成一條邏輯鏈路，每個埠速率為500Mbps。埠匯聚就是有10條乙太網線要求接入，但是實際就有一個物理介面，可以使用交換機，將10個乙太網介面數據匯聚到一條乙太網鏈路上。
2. 極貳openwrt 編譯 7620a+7621e，能夠開啟 2.4G，5G 該怎麼打開
1. 下載openwrt最新代碼
2. 下載openwrt官方的7621e驅動https://github.com/openwrt/mtk-wifi-gpl
3. 參考https://code.google.com/p/openwrt-hiwifi/, 打上hc5761的補丁，使用其hc5761的config，並開啟mtk-wifi-gpl
4. 編譯完成通過ttl，sysupgrade -F -n openwrt-ramips-mt7620a-hiwifi-hc5761-squashfs-sysupgrade.bin刷機
5. 完成重啟，2.4G能夠開啟

從log看，5G已經識別了。
3. openwrt 在網卡eth0.2上獲取IP失敗! ,認證成功但無法上網
獲取IP失敗，你還能認證成功，碉堡了。在你的電腦IPV4設置里把DNS自動獲取改成手動獲取，然後把DNS填進去試試。
4. openwrt如何轉wifi為有線信號
啥配置文件都不用改好么?刷最新版的openwrt上去,然後進luci裡面,找到介面-無線-搜索到你的無線網,然後輸入密鑰點加入,保存並應用就好了么.....
5. 入介面選擇vlan 10 出介面選擇上聯口eth1
先看看網路拓撲，MW305R+刷OP，單口上聯ROS。設置兩個SSID，一個是無VLAN，一個VLAN ID 200
下面是OP的網路配置：
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'
無線部分配置：
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'
這樣設置後，無VLan的介面會失效，不能從ROS獲取IP。如果兩個SSID都設置VLAN ID，ROS也增加對應介面，這樣就沒有問題。
該如何設置才能使得無VLAN的介面可以正常上聯
6. openwrt怎麼知道哪個商品是eth0.1，eth0.2，eth0.3
我也不知道這個問題有沒有標准答案，從我的經驗來講，有這么兩個辦法
你把所有介面上的網線都拔了，只留一根網線插在你的網口上。這時候你在OpenWRT的命令行里跑ifconfig，看哪個NIC還有顯示，那插上去的口就代表那個NIC。（注意，這個方法只適合物理介面，不適合虛擬介面）
跑ifconfig裡面會有各個NIC的IP的顯示，如果你能區分插在各個網口上的機器的網段，那就能區分出NIC對應的介面
需要注意的是，eth0.x很多時候都是VLan劃分出來的子網（在eth0這個交換機上），所以你看到的介面可能是一模一樣的（比如8口或者24口交換機），也可能是不一樣的（比如家用的路由器，一般eth0.1代表Wan口，eth0.2表示lan口）。這是一個虛擬的劃分概念，和實際介面的外形沒有直接聯系
7. 路由器能刷kali linux固件么
以發行版Ubuntu為
例（如果你在Windows下，可下載Ubuntu的ISO文件，再用wubi安裝Ubuntu，可免去重新分區的麻煩），下載Buffalo
WHR-G300N V2路由器的FTP版固件文件，放到Ubuntu的/home目錄下，改名rf.bin，刷入的方法如下：
1.在Ubuntu中，保證正常訪問互聯網軟體源的情況下，找到並進入「terminal」（終端）界面；
2.輸入「sudo apt-get update」按回車，根據提示輸入管理員密碼，開始更新軟體包信息；
3.輸入「sudo apt-get install tftp」，開始安裝tftp軟體包；
4.用牙簽捅住路由器復位按鈕10秒
5.拔掉路由器的電源；
6.用網線連接電腦LAN口與路由LAN口（注意不要接成藍色的WAN口）；
7.輸入「sudo service networking stop」（適用Ubuntu 9.10或以前版本）或「sudo service network-manager stop」（適用Ubuntu 10.4或以上版本）命令，以關閉系統的網路管理服務；
8.輸入「ifconfig」查看是哪一個網卡與路由器相連，一般為「eth0」代號的網卡；
9.輸入「sudo ifconfig eth0 192.168.11.2」，強行設定「eth0」代號的網卡的IP為192.168.11.2（因為Buffalo路由器的bootloader里的默認是IP是192.168.11.1）；
10.輸入「sudo ifconfig eth0 netmask 255.255.255.0」，設置掩碼；
11.輸入「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路由器背面的標簽上可查到，處可不輸入冒號間格。
12.輸入「tftp」，出現「tftp>」提示符；
13.輸入「verbose」，出現「Verbose mode on.」提示；
15.輸入「binary」，出現「mode set to octet.」提示；
16.輸入「trace」，出現「Packet tracing on.」提示；
17.輸入「rexmt 1」，每格一秒嘗試一次推送；
19.輸入「timeout 60」，推送嘗試的時間不超過60秒；
20.輸入「connect 192.168.11.1」，連接路由器（實際上並沒連接，只是為連接作好准備）；
21.輸入「put rf.bin」，會提示失敗，並每格1秒就嘗試一次推送；
22.接上路由器電源，路由器將啟動，LED會亮起來，約10－20秒後，會顯示開始推送以及傳輸進展；
23.提示推送傳輸完成後再等待5－10分鍾，路由器的紅色LED燈閃爍，然後熄滅，最後無線LED指示燈亮起，表示固件刷新成功；
24.輸入「quit」退出tftp界面；
25.
輸入「sudo service networking start」（適用Ubuntu 9.10或以前版本）或「sudo service
network-manager start」（適用Ubuntu 10.4或以上版本）命令，以開啟系統的網路管理服務；
26.輸入「exit」退出終端界面；
27.
如果rf.bin文件的來源於Buffalo官方，則路由IP是「192.168.11.1」，網卡IP必須是「192.168.11.X」才連接，用戶
名為root，密碼為空；如果rf.bin文件的來源於OpenWRT、Gargoyle、DD-WRT，則路由IP是「192.168.1.1」，網卡
IP必須是「192.168.1.X」才能連接，DD-WRT用戶名和密碼自定義，Gargoyle的默認密碼是「password」。
8. WDR4300 刷了openwrt後 怎麼設置 雙wan口 我一個是 電信 一個是移動 這款支持 雙wan嗎
（一）首先在Network---Switch裡面設置如下：
（三）其餘的pppoe賬號設置不需要我多說了吧
