CAS is the Central Authentication Service for our campus. Whenever you log in to a service CAS is used to either check that you have already been properly authenticated or to have you authenticate, including two-factor authentication (2FA) using Duo. Windows SSO (Single Sign-On) is a similar mechanism for allowing you to connect to various […]

Network Configuration for a Wi-Fi Access Point
This page describes how to configure the network interfaces for a Raspbery Pi running as a Wi-Fi Access Point (AP). This is just one step in a larger list of instructions, which can be found on the page Raspberry Pi Wifi Access Point. The instructions here do not include the routing, which is covered later. […]
Using Duo Security Two-Factor Security at SUNY New Paltz
SUNY New Paltz is in the process of adding Two-Factor Authentication (2FA) to their adminstrative computer systems, and I have been trying it out. This is a report on some of the things I’ve learned, such as how to get it to remember you for 5 days without having to accept all third-party cookies. Two-Factor […]
Raspberry Pi WiFi Access Point
I have an old iPad which has been dropped so many times that a piece of wire fell out the side, and I think that wire was the WiFi antenna. The iPad can only connect to WiFi when it’s close to the access point or when the signal is very strong. I figured out that […]
Raspberry Pi Access Point Routing
This is the last step required to turn a Raspberry Pi into a WiFi Access Point. If you want to see all the previous steps, start with “Raspberry Pi Wifi Access Point“. When you get to this page you should already have done the following: Configured both network interfaces, Set up hostapd (a daemon which lets […]
DHCP daemon on Raspberry Pi
DHCP stands for “Dynamic Host Configuration Protocol”. The DHCP daemon is the process which assigns IP addresses to computers when they join a network, and gives them other important information about the network, including DNS server addresses. A local network used for a wireless Access Point usually has a DHCP server associated with it. […]
Configuring hostapd on Raspberry Pi
The daemon hostapd is a Linux service which enables a “host” computer to become a WiFi Access Point (AP). Thus “host” + “AP” + “d” (for daemon) gives the name hostapd. I originally learned to set up hostapd from instructions on Pastebin written by user Dryfire117,1 andlater found useful instructions on the Raspberry Pi […]
