Overview of this book

Linux can be configured as a networked workstation, a DNS server, a mail server, a firewall, a gateway router, and many other things. These are all part of administration tasks, hence network administration is one of the main tasks of Linux system administration. By knowing how to configure system network interfaces in a reliable and optimal manner, Linux administrators can deploy and configure several network services including file, web, mail, and servers while working in large enterprise environments. Starting with a simple Linux router that passes traffic between two private networks, you will see how to enable NAT on the router in order to allow Internet access from the network, and will also enable DHCP on the network to ease configuration of client systems. You will then move on to configuring your own DNS server on your local network using bind9 and tying it into your DHCP server to allow automatic configuration of local hostnames. You will then future enable your network by setting up IPv6 via tunnel providers. Moving on, we’ll configure Samba to centralize authentication for your network services; we will also configure Linux client to leverage it for authentication, and set up a RADIUS server that uses the directory server for authentication. Toward the end, you will have a network with a number of services running on it, and will implement monitoring in order to detect problems as they occur.

Configuring NGINX with TLS

While we've covered Apache's HTTPD server so far in this chapter, there are other options available for use on Linux platforms as well. One popular offering is nginx (pronounced engine-x), which works well as a lightweight, fast, multithreaded offering.

We're going to look at how to set it up as a TLS webserver.

How to do it…

Installing on Ubuntu 14.04:

  1. Install the software:

    sudo apt-get install nginx
  2. Configure the server for TLS by uncommenting the HTTPS server section of /etc/nginx/sites-available/default while populating the ssl_certificate, ssl_certificate_key and ssl_ciphers variables.

  3. Restart the daemon:

    sudo service nginx restart

Installing on CentOS 7:

  1. On CentOS 7, nginx is not included in the default repos, but is available in the Extra Packages for Enterprise Linux (EPEL) repository.

  2. Install the EPEL repo:

    sudo yum install epel-release
  3. Install the nginx package:

    yum install nginx
  4. Configure the server for TLS by adding an https server section to /etc/nginx/nginx...
