After Install Centos 7

I have just installed Centos 7 with the minimal installation options, lots of things which were taken for granted by me were not installed,

Question :
I have just setup on RHEL 7.0/CentOS 7.0 minimal server installation but i notice ifconfig and netstat command not found. How to make those command working ?
Solution :
By default, ifconfig and netstat utility is not installed on RHEL 7.0/CentOS 7.0 minimal server installation. You need to install net-tools utility manually, this include ifconfig and netstat command.

1. Update your centos 7 after instalation

yum update -y

2.  Install netstat for Check Listening Network Ports

yum install net-tools

 Try ifconfig command :

[root@localhost ~]# netstat -tulpn

Everybody says that Linux is secure by default and agreed to some extend (It’s debatable topics). However, Linux has in-built security model in place by default. Need to tune it up and hardening your linux as per your need which may help to make more secure system.
