Solve the connection authentication problem of Sun Yat-sen linuxH3C

Solve the connection authentication problem of Sun Yat-sen linuxH3C-general Linux technology-Linux technology and application information. The following is a detailed description. This solution comes from liangxiaorui

Sun Yat-sen University campus network uses Huawei H3C Certification software. In fact, the installation guide for Internet authentication included in it is incorrect: first, to install H3C requires a C ++ Library (of course, this is a very small problem. You can download it from other computers online ); the biggest problem is that this authentication must be temporarily switched to the Super User identity for normal use, but there is no prompt, it is very easy to make mistakes! When we switch to the H3C folder using the cd command as instructed, run the command. /pre. ps, you can continue to install it. At last, you can use the linux1x-u username/password-n eth0-d command to try the authentication and a few simple words will appear, including pass automatically, you can use linux1x-v to find that both the IP address and subnet mask are available, but the amount of data sent and received is small, so you cannot access the Internet. The reason is that the IP address cannot be refreshed. According to my own tests, fedora and redflag Users enter su on the terminal before installation, press enter, and enter the password to switch to the Super User identity for running, and then follow the instructions to install it. For ubuntu and openSUSE, you only need to add sudo before the command in the manual. I also found that this H3C has a Bug. I am using Ubuntu linux. In a few cases, the input of sudo linux1x-d for boot authentication does not respond, that is, authentication is not performed. Solution: Enter the complete path of cd H3C, press enter, enter sudo linux1x-u username/password-n eth0-d, and press enter to enter the password.
