0. Introduction of toolsThe purpose of Dnsenum is to gather as much information as possible about a domain. The program currently performs the following operations:1) Get The host ' s Addresse (A record). 2) Get the Namservers (threaded). 3) Get the MX record (threaded). 4) Perform AXFR queries on nameservers and get BIND versions (threaded). 5) Get extra names and subdomains via Google scraping (google query = "Allinurl:-www site:domain"). 6) Brute f

By default, after the vmwarevm and Ubuntu 12.04 are installed, the IP address is dynamically obtained. The IP address may change every time it is started, so it is necessary to configure a static IP address for it.
First, confirm the network configuration with Nat, determine the vmnet8 subnet address, and open the virtual network editor.
Make sure that the vmnet8 IP address on the Windows host is configured192.168.159.1.
Open the terminal in ubuntu12.0
NSLookup command at most to test it.Whether the DNS is normal.
We only need to configure iptables after confirming that the ADSL connection is correct.
Modify/etc/sysconfig/iptables (delete all the original content ).

Enter WQ to save and exit. Next, restart the resolvconf program to make the configuration take effect:
#/Etc/init. d/resolvconf restart
Go to the/etc/resolv. conf file and write the self-added DNS server! This is a perfect solution!
In 12.04, you can also use a simpler method:

From: http://vinsol.com/blogAt vinsol, we have been developing and deploying Rails Applications for more than four years. During this period, we have identified some best practices that we prefer to follow while deploying rails application to production server.
Below is the checklist of these practices:
1. Ensure that ns records and MX records are changed if they need to be changed
Changing nameservers will point the domain to the hosting server, and
-* options are implemented by the resolvconf package, if installed
DNS-nameservers 8.8.8.8 # DNS, separated by Spaces
Sudo/etc/init. d/networking restart # Start the nic and the eni will be disconnected.
Sudo/etc/init. d/networking force-Reload # force loading. This is better, and the terminal will not be disconnected.
