    "©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."

How to use the NMAP Security Scanner on Linux - 1 views

  •  
    "Nmap is a free and open source network discovery and security auditing utility that is widely used in the Linux users community as it is simple to use yet very powerful. Nmap works by sending data packets on a specific target (by IP) and by interpreting the incoming packets to determine what posts are open/closed, what services are running on the scanned system, whether firewalls or filters are set up and enabled, and finally what operation system is running. Those abilities are used for a wide variety of reasons and howtoforge.com is not encouraging nor suggesting the use of nmap for malicious purposes"

How to configure peer-to-peer VPN on Linux - Xmodulo - 0 views

    "Last updated on October 9, 2014 Authored by Dan Nanni Leave a comment A traditional VPN (e.g., OpenVPN, PPTP) is composed of a VPN server and one or more VPN clients connected to the server. When any two VPN clients talk to each other, the VPN server needs to relay VPN traffic between them. The problem of such a hub-and-spoke type of VPN topology is that the VPN server can easily become a performance bottleneck as the number of connected clients increase"
