What is the package name for nslookup in Linux?
So I can run it with --enable-cli . But when I do, I get no output.
What is the alternative command to nslookup in Linux?
I use it on OSX. It's not an exact replica, but the nsswitch.conf configuration file makes sure that nameservers get looked up first.com
Server: 127.0.1
Address: 127.1#53 Name: google.com Address: 216.239.56.104
And with nsswitch.conf -rw-r-- 1 root 566 Oct 18 21:05 /etc/nsswitch.1#53 Non-authoritative answer: Name: google.59.109
As you can see, this lookup uses mdns4minimal (which should be available on your system) first. If it doesn't succeed, it falls back to dns as defined in the nsswitch.conf file, and as you can see the name of the file being looked up is returned as the result.
Now I'm not sure what your real question is. Maybe you want to know what the difference is between the two commands? But nslookup and dig do exactly the same thing under the hood.

When the system fails to resolve a given hostname it's best to try to change the setting back to a local DNS only server (in case OpenDNS is not accessible or if the IP address changes).
If after that, you still cannot access the host on OpenDNS servers, then you can try the following alternative: Make sure to restart Firefox after doing so. Type about:config into the address bar of the Mozilla Firefox address bar. Search for security.tlsfallbackhost The value under the security tab should be a valid IP address from a local DNS.
