- Off-course you should use a username and password of your choice. Press Done.Have patience and wait for the completion of the setup. After completion of the installation, it will ask to reboot the server, just press Finish configuration. The server reboots and will request your username and password afterwards.
- Setting Up DNS Server On CentOS 7. For example, if we type www.unixmen.com in browser, the DNS server translates the domain name into its associated ip address. Since the IP addresses are hard to remember all time, DNS servers are used to translate the hostnames like www.unixmen.com to 173.xxx.xx.xxx. So it makes easy to remember the domain names instead of its IP address.

During linux installation I selected 'minimal' option:
In this tutorial, we will go over how to set up an internal DNS server, using the BIND name server software (BIND9) on CentOS 7, that can be used by your Virtual Private Servers (VPS) to resolve private host names and private IP addresses. Install BIND on DNS Servers. Use nslookup—included in the 'bind-utils' package—to test.
When I went to run the nslookup command to look up an IP address I got the error message

The minimal install likely did not come with the
bind-utils
package, which I believe contains nslookup

In processing, traceroute is a computer network diagnostic tool for showing the path and measuring transit delays of packets over an Internet Protocol (IP) network. The historical backdrop of the course is recorded as the round-trip times of the packets got from each remote node in the path. Each hop indicates the total time spent to establish the connection.
When you connect with another PC, your traffic does not go straightforwardly to the machine you are attempting to connect with. Rather it goes through different machines on the Internet known as switches. These machines fill the sole need of controlling how your activity gets to your destination. On the off chance that any one connection fails, you will not be able to connect to the intended destination.
Output:
Traceroute sends out three packets per TTL increment. Each column corresponds to the time is took to get one packet back (round-trip-time). This tries to account for situations such as:
A traceroute packet is routed along a different link than other attempts
A traceroute packet is routed along a different link than other attempts
A traceroute packet is dropped
Disable IP address and host name mapping
At whatever point traceroute command is run, it will demonstrate some host names with their IP addresses. Traceroute comes with a facility with which the mapping of IP addresses into their host name is deactivated. We can do this using ‘-n’ switch.
Output:
Configure Response Wait Time
At whatever point traceroute issues a test, it wait for the response from the switch for some time span called “Response Wait Time”. The ‘-w’ option set the time (in seconds) to wait for a response to a probe. Default wait time is 5.0 sec.
Output:
Configure Number of Queries per Hop
As already explained earlier, the traceroute utility sends 3 packets per hop to provide 3 round trip times. This default value of 3 is configurable using the option ‘-q’. This option expects an integer which it sets as new value of number of probes per hop.

Configure the TTL value to start with
Traceroute utility is flexible enough to accept the TTL value that the user wants to start the utility with. By default its value is 1 which means it starts off with the first router in the path but using the ‘-f’ option a new value of the TTL field can be set.
