[zhu yu tang] I want to ask a question, which is the router software upgrade, saying that I want to "start a TFTP server on the computer in the LAN and place the downloaded file in the service path of the TFTP server"! But I don’t know how to turn it on, please tell me in detail, thank you!
[Nian Laohu] I don’t know what brand and model of router you are using, but since the router software system is upgraded through TFTP transmission, there should be detailed instructions for upgrading methods in the instructions included with the router, and the TFTP server software for upgrading is placed on the included CD. Maybe you will say that I don’t have these things, so it doesn’t matter. Let me explain the specific method to you.
First, download Cisco TFTP Server from /?Go=Show::List&ID=6133 (if you know the router brand, you should also have the corresponding TFTP server software download to the router manufacturer website), and install it on the machine where the router upgrade file is placed (at this time, you must set the IP address of this machine so that it is on the same network segment as the router's LAN IP). Then start the TFTP server software, and set the "TFTP server root directory" in the options settings (usually under the "View" - "Settings" menu) to the directory where your router upgrade file is located. Press "OK", and the TFTP server settings are completed.
Next, use telnet to log in to the router and use the tftp command to upgrade the router's software system in the router configuration mode. The general command form is "tftp TFTP server IP address file name", such as input "tftp 192.168.0.2 2006.2b", which means downloading a file named 2006.2b from a TFTP server with IP address 192.168.0.2 to upgrade the router. For specific command parameters, you also need to refer to the router's instruction manual or directly view the command help.
