    "©2016 Chris Binnie On a continually changing network it is often difficult to spot issues due to the amount of noise generated by expected network traffic. Even when communications are seemingly quiet a packet sniffer will display screeds of noisy data. That data might be otherwise unseen broadcast traffic being sent to all hosts willing to listen and respond on a local network. Make no mistake, noise on a network link can cause all sorts of headaches because it can be impossible to identify trends quickly, especially if a host or the network itself is under attack. Packet sniffers will clearly display more traffic for the busiest connections which ultimately obscures the activities of less busy hosts."

    "I came across Salt while searching for an alternative to Puppet. I like puppet, but I am falling in love with Salt :). This maybe a personal opinion but I found Salt easier to configure and get started with as compared to Puppet. Another reason I like Salt is that it let's you manage your server configurations from the command line, for example:"

    "Welcome to the FirewallD project homepage! FirewallD provides a dynamically managed firewall with support for network/firewall zones to define the trust level of network connections or interfaces. It has support for IPv4, IPv6 firewall settings and for ethernet bridges and has a separation of runtime and permanent configuration options. It also supports an interface for services or applications to add firewall rules directly."
