I recently bought myself a Raspberry Pi B+ (picture semi-related). I had no initial plans on what I was going to with it, but I ended up installing Raspbian and setting up a PPTP VPN in my home’s DMZ (There are plenty of guides online if you are looking to do this). The reason I went with PPTP over IPSEC or L2TP is because PPTP is so easy to set up. It took about 15 minutes to get it up and running. Even though PPTP is no longer considered a “secure” VPN, I wanted to be able to have an encrypted connection anytime I was on a public WiFi.
I recently took my company of about 140 off of our current POP/SMTP email system (yes, companies still use POP for email) and onto Microsoft’s Office 365 Hosted Exchange. They give you PowerShell access to your Exchange 2013 server so there is a lot you can do to help reduce the time it takes to get your environment ready. Here are some quick and easy PowerShell scripts I wrote to assist with my transition.
