What is similar to nslookup in Linux?

I want to check the IP address of my ISP, and the DNS server it provides.

Is there anything similar to nslookup in Linux? The resolv.conf file contains all the information needed for you to query your ISP's DNS server. The resolvconf package, included in the default installation, takes care of this.conf is described in the file /etc/resolvconf/resolv.d/tail.

There are two additional files in that directory, 50-ubuntu.conf and 99-resolvconf. They are automatically created by resolvconf during the installation.04 you can use the following command. It works as nslookup on Windows.

Cat /etc/resolv.conf I added a couple of nameservers to resolve. You can use the following command in bash to view DNS server info: nameserver 8.8

What replaced nslookup in Ubuntu?

Nslookup has been replaced by NetworkManager.

That way we do not have to rely on local cache servers anymore. But my question is what replaces that (the software we use to connect to the Internet). Is it still called network-manager and/or wifi-radar? And do I need it or could I just remove those and be fine?

@jwre - the problem with your original post was that you needed nslookup in Ubuntu before (before NM/wifi-radar), while after it has been replaced with Network Manager. Your solution to "install dnsmasq" won't work, as dnsmasq does not replace NetworkManager (its a caching/query DNS server, which uses NM to fetch DNS info). What you want is another option besides NetworkManager to connect to the internet.

Nslookup is a utility built into BIND and used to query for domain information. NetworkManager, the replacement to network configs, is responsible for creating a network connection. You should be able to delete nm-applet, wifi-radar and replace them with sudo apt-get purge network-manager and install nm-applet.

PierrreApr 11 '12 at 20:15. I used to run 'systemsettings' (for K/Ubuntu) to configure my network connection. The command to list all available networks was: /usr/bin/nmcli dev list --type=wifi.04). How do I add the same functionality using nmcli/network-manager?
