I have just recently switched from windows to Linux and i am unable to connect to the Ethernet. My university requires authentication software in order to connect to the Ethernet. They provide the download links on their website for the Linux version of the software. If you would like to take a look at the software here's the address http://www2.zzu.edu.cn/service/sys/RG_SU_For_Linux_1_30_setup.zip
After I downloaded the file and extracted I used sudo bash rjsupplicant.sh
as well as the chmod +x
command suggested in the Zip's readme. Both commands returned the error
Sysctl: write error: Bad file descriptor
Sysctl: write error: Bad file descriptor
Sysctl: write error: Bad file descriptor
Please select dhcp mode, using "--help" command to detail.
When I applied for an Ethernet connection at the university office I was given an ip address, gateway, subnet mask, and DNS server. I also needed to spoof my Mac address in order for the software to properly authenticate me. I have already changed all the settings for my wired connection via system settings>network>wired>options under the Ethernet tab and ipv4 settings to the values provided by the university network office
I have attempted to look up solutions, however, I do not have the expertise to follow them through :(. I would appreciate a step by step solution. I also apologize in advance if it is against the forum rules to post links.
