Ubuntu server resolves unreachable extranet issues

　　　Ubuntu server resolves unreachable extranet issues

When setting up access to an extranet on Ubuntu server, you need to set up DNS, typically adding DNS to the/etc/resolv.conf file.

However, after you add DNS to the/etc/resolv.conf file, you can access the extranet, but when you restart Ubuntu server, the DNS is lost in the/etc/resolv.conf file.

Solution:

Add DNS separately to the

$ vi/etc/resolvconf/resolv.conf.d/base

For example, Shanghai DNS, add in, save can

NameServer 202.96.199.133

$ vi/etc/resolv.conf

NameServer 202.96.199.133

Save to exit

Then restart Ubuntu Server to see that the content in/etc/resolv.conf is not lost, so you can access the extranet!
