September 11, 2018: Managing Systems with Ansible

Ansible is an OSS IT automation engine, in the vein of Chef and Puppet. But what exactly can you do with it? John Gunkel filled us in. He covered key concepts, package management, templates, roles, GUI interfaces, and more!

RTFM: tcpdump(1) with Adam Thompson

Debugging an application's behaviour is sometimes easier to do by looking at the interactions it has with other systems on the network than by examining the application itself. Modern UNIXes all come with a tool, tcpdump(1), that can examine, filter, decode, and log all the traffic seen at a network interface - whether it originates on that system or not. Adam discussed the most common options for tcpdump(1), and demonstrated a simple example.

October 9, 2018: Reproducible Builds

Many of us run some amount of Free and/or Open Source Software, but how can we ever be sure that what we're actually running was built from the allegedly published source code? Whilst not a complete security solution in and of itself, this project helps influence and improve security and development as part of a wider set of policies. Presented by Muz, this short talk introduced the issues with trying to obtain reproducible builds, and some of the work that has been done to date on certain code bases, particularly with the Debian distro.

RTFM: netcat, with Wyatt Zacharias

A look into a computer networking utility for reading from and writing to network connections using TCP/IP protocol, designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts.

Note that there are two versions of netcat (or the nc command) that are widely available: the traditional "Hobbit" netcat(1), and the ncat(1) command that comes as part of Nmap. Wyatt's presentation focused on the latter. (Adam Thompson focused on the former in a June 2014 RTFM.)

November 13, 2018: Build an IP Captive Portal from Scratch

(For Fun and Education, but Not for Profit)

Love 'em or hate 'em, captive portals are widely used to restrict Internet access to authorized users. What if you need to set one up, but all the "canned" solutions aren't quite right for your use case? This presentation by Gilbert Detillieux will show you the various components that make up a captive portal, and how you can set one up from scratch, using Linux Netfilter/iptables, the Apache web server, ISC DHCPD and BIND, and some custom back-end scripting.
