How to convert Cisco Aironet 1130 to autonomous

     I got some Cisco Aironet 1130 AP’s from Amazon a couple of month ago. but even those are brand new, it seems like there is no Cisco OS inside of the AP. From Cisco website, It sounds like the AP that we are using may be a LWAPP (Lightweight) AP. This is why we can’t configure it via the web. The solution is follow these steps showing below to revert them from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:

1. Set the static IP address of your PC on which your TFTP server software runs to 10.0.0.2
2. Download the TFTP server software. (e.g. one software called TFTPD32 can be downloaded from here)
3. Make sure that the PC contains the access point image file (can download from Cisco website) in the TFTP server root folder and that the TFTP server is activated.
4. Disable any software firewall products, such as Windows firewall etc.
5. Rename the access point image file in the TFTP server folder to c1130-k9w7-tar.default.
6. Connect the PC to the Ethernet port of access point.
7. Disconnect power from the access point.
8. Press and hold MODE while you reconnect power to the access point.
9. Hold the MODE button until the status LED turns red (might be 20 to 30 seconds) and then release.
10. The access point should receive the img file from the TFTP server
11. Wait until the file has been transferred, the access point will reboot as indicated by all LEDs turning green followed by the Status LED blinking green.
12. After the access point reboots, connect it to the DHCP server, and get the IP of AP by DHCP server.
13. use IE to connect the AP GUI by typing the IP

二倍距离

     林亨泰这个名字，只记得以前在某个李敖的节目中听到过。只知道是个诗人，只知道写过诗。今天再看到这个名字，俨然已变成教育界争论的中心。能否读懂他的诗，似乎已变成了能否进入大学校园的衡量标准。该诗全文如下：

二倍距离
　　—–林亨泰

　　你的诞生已经
　　诞生的你的死
　　已经不死的�
　　的诞生已经诞
　　生的你的死已
　　经不死的�
　　一棵树与一棵
　　树间的一个早
　　晨与一个早晨
　　间的一棵树与
　　一棵树间的一
　　个早晨与一个
　　早晨间
　　那距离必有二倍距离
　　然而必有二倍距离的

     暂无评论，对这首诗……

Google的结局？

     听说Google要退出中国了。不管是什么原因，对于普通用户来说，毕竟不是个好消息。
     目前最关心的，仍只是停留在国内还能不能看到肖恩D++上那一堆Google的程序……

VI中替换命令的具体用法

      VI中替换命令可以简单的写成以下命令：

:[range]s /[st1]/[st2]/g

其中:

• [range]表示替换命令的查找范围：
  • 1. “%” 表示所有行
  • 2. “.” 表示当前行
  • 3. “$” 表示最末行

       例如，:%s/[st1]/[st2]   表示查找文件中所有[st1]的字符串，并替换成[st2]
                :-5，+5s/[st1]/[st2]   表示查找目前行的前五行和后五行中[st1]的字符串，并替换成[st2]

• “s”表示替换命令
• [st1]表示要查找的字符串
• [st2]表示希望把匹配的字符串变成的字符串
• “g”表示可选项，放在命令末尾,表示对搜索字符串的每次出现进行替换;不加 g,表示只对搜索字符串的首次出现进行替换;g 放在命令开头,表示对正文中所有包含搜索字符串的行进行替换操作。
