I have read that the hosts file type is ASII, and I changed the DNSclient to manual. if it is disabled, it still does not work. The hosts file is invalid. In the hosts file, write 127.0.0.1 www.baidu.com to ping the domain name as the public IP address.
I have read that the hosts file type is ASII. I also changed the DNS client to manual, but it is still disabled.
