Telecoms: ePSK - Multiple Pre-Shared Keys

Originally posted on the Cambium Community Networks Just in case you missed it cnMaestro Version 2.2.1 (Cloud and On-Premise), brings us a great new feature called ePSK. If you’re not familiar with ePSK it’s maybe because Cambium are too modest to toot their own trumpet so I’m going to do it for them. In short ePSK gives each user a unique PSK (pre-shared key) when using WPA2-Personal, for me to explain why this is such a useful feature let me first explain the problem with using a shared PSK across the whole WLAN. When a wireless client connects to an AP it completes a 4-Way handshake, this generates the encryption keys used to encrypt wireless traffic. For the 4-way handshake to work it is a requirement that both the client and AP know the passphrase, however the passphrase is never transmitted over the air thereby making this exchange reasonably secure. But what happens when a 3rd party already knows the passphrase? It means they just need to capture the 4-way handshake to gener...

My Musings: Gladiator (2000) movie

Yesterday, I watched Gladiator, released in 2000, starring Russel Crow , Joaquin Pheonix and Connie Nielson Sad to say it was my first time to watch such an incredible and old movie. The plot was predictable at first when Commodus murdered his father and then the story continues.  You could almost see the evil in Commodus' eyes when he first appeared on the scene. His demeanor, his gait, his stance all reeked of someone who was disturbed. As the movie unfolded, it became clear: he sought a love that was not bestowed upon him as he desired. I know its all a movie and stuff but an important lesson drawn from this is that parental duties comes before all else. Marcus was out winning wars and his son was neglected. Commodus lacked an accessible role male model to look up to guide him in the ways of life. Perhaps he had, but his father could not be replaced. Fathers, be present for your sons.

Multimedia: Sound mixing

On my way to work this morning, I heard on the Radio, Raude by Black Rose of New Caledonia. It's been a while since I've heard that song in full.  It was an intriguing experience since I had a little experience in sound and mixing. It was a masterpiece, in my opinion. On the little speakers I was listening to, the drums clear and had presence. I felt the beat. It wasn't too much that it killed the speaker and it wasn't too little that was drowned out by the instruments.  The good sound may also have been due to the quality of the sound file played. I'm pretty sure that Legend FM was playing the song at 128kbps or more.  In retrospect, most of the new artists in PNG are very creative but they miss out on the technical aspects that makes the experience immersive. I hope they realize this sooner reach out to Technical Creatives to enhance their audiences experiences.
