Connect to the network in Ubuntu and start learning.

Ubuntu was installed on July 15, June 9. During the installation process, I was not prompted to set the root password. I only set my username and password, after entering the system, run the Sudo-s command to switch to the root permission, modify the permissions of myxrgsu (run the CHMOD command), or change the owner of myxrgsu to my username (run the CHOWN command) you can. Specifically, myxrgsu on my computer is the owner's read and write permissions, and group and others are the system permissions. I think I usually connect to the network under my own user name, so I will change myxrgsu to my own User name: chown cm/usr/bin/myxrgsu

The following figure shows the specific file and processing process. You can extract a segment from the network to find the file and download it to the required file:

 First, decompress myxrgsu.rar in Windows system, and put the extracted files and folders in the hard disk partition where the non-Ubuntu system is located. Of course, it is also possible to put the files in the USB flash drive and memory card. Then, log on to Ubuntu as administrator. In ubuntu, copy and paste the extracted files and folders /Home/Administrator directory, it is recommended to directly put the files in the bin and Lib folders in/home/ Administrator to facilitate the next copy operation. After the file is copied, myxrgsu is installed. Open "attachment" -- "Terminal ". Enter the command "sudo CP" in "terminal" /Home/Administrator/myxrgsu/usr/ Bin, and then press Enter. (Note: After you press enter, a password prompt will appear. Enter the password and press Enter. The password is not displayed on the terminal, therefore, if no error message is displayed after you press enter, you can continue. Also, the input command "CP" means copy) to continue, and then enter the command "sudo CP" in the terminal /Home/Administrator/Libpcap. So. 0.6 . 2 /Usr/ Then press Enter. Continue, enter the command "sudo CP" in the terminal /Home/Administrator/Libpcap. So. 0.8 . 3 /Usr/ Then press Enter. Continue, enter the command "sudo CP" in the terminal /Home/Administrator/libstdc ++. So. 5.0 . 7 /Usr/Then press Enter. Then, configure the network and fill in your IP address and other information in the network settings. Finally, run myxrgsu. Enter the command "sudo myxrgsu" in the terminal and press Enter. Enter your Ubuntu system password in the following password prompt and press Enter. If the password is correct, you will be prompted to enter the user name (your campus network ruijie user name), enter the user name, then press enter, then prompt to enter the password, enter and press Enter. Then press enter along the way, and then wait until the authentication is successful. Note: Do not close the terminal after the authentication is successful to minimize it. Every time you connect to the Ubuntu system, you can open the terminal, enter "sudo myxrgsu", Press enter, and then enter the system password, and then the user name and password ...... When copying files in the bin folder, you only need to copy myxrgsu, that is, you just copy the file myxrgsu In/usr/bin, set Libpcap. So. 0.6 . 2 copy to/usr/lib and put libstdc ++. So. 5.0 . 7 copy to/usr/lib and put Libpcap. So. 0.8 . 3 copy to/usr/ Bin ,. Because of security issues, these copies can only be performed in the form of commands on the terminal. -- Paste method.

The operation was performed according to the preceding instructions, and I was prompted that libstdc ++. So was not found.. 5. libstdc ++ is found on it. so.5.0.7, I guess myxrgsu requires libstdc ++. so.5. rename so.5.0.7 to libstdc ++. copy so.5 to the/usr/lib folder, and then run sudo myxrgsu!
