Monday 17th October.
Peter Postmus gave a presentation on his experiences with the Raspberry Pi 2 and 3 and he demonstrated how to turn a Raspberry Pi into a Network Attached Storage (NAS).
He gave an overview of the capabilities of the different models, discussed the different operating systems that could be used, and showed how to install the OS. He then showed how he had set up a Raspberry Pi to work as a NAS and a media server. He was using Raspbian, with OpenMediaVault for the NAS and LibreSonic for media streaming.
Then Geoffrey Smith continued the topic of security from his presentation in April. He discussed different ways to store passwords and showed how easily passwords can be cracked when they’re stored as a simple hash. He then discussed the Bcrypt algorithm, which can be used to store passwords well salted and encrypted. He discussed vulnerabilities in systems such as SQL injection and cross site scripting and showed us some techniques and technologies to help write secure programs and systems. These included the use of client certificates and how to keep session cookies secure.
The meeting was at the Melbourne Men’s Shed, situated in the Federation Square Car Park off the Russell St Extension.
