can not resolve domains anymore

dglocke · 11-02-2017, 12:04 PM

Using Ubuntu 17.10 on a home made desktop computer. This setup has been working for at least 5 years. I also have Windows 7 on this computer and I have no problems with the internet connections. I have a newer home made computer with Ubuntu & Windows 7 on it. No problems with the newer computer.

I can ping 8.8.8.8 & it works. But if I ping www.google.com I get Name or Service not found. I can not connect to any server. Any ideas?

Please let us &future searchers know what broke & what fixes your case!!!

I also encounter this 'new feature'; might it be malware from the 'never-systemd' movement???

You might need to add your DNS server to your /etc/resolv.conf file.

Here's mine for reference:

Code:

#nameserver 8.8.8.8
nameserver 192.168.43.1

Good luck!

Isn't Ubuntu's /etc/resolv.conf just a symlink? (ls -l it)
Is vi /run/... 'persistent'?

Why? What ?default choice? is wrong, for a 'typical "end" user'?
