    First journal entry for the new year. It’s been a few months since I’ve had anything to add personally. Life has been pretty crazy with a newborn that I sort of put this notes blog down for a little while. Though in the process; when I had down time, I created some fun tools that I’m a pretty big fan of. Might even provide a little more information about them in their own separate articles.

    I wrote a command line application that will obtian the notBefore and notAfter values from within a TLS certificate and run a test on the current tiem of the machine it’s running in. Along with the timezone that the machine is running in. The name of the application is called certchecker and I wrote this in Go so I could have a quick ad-hoc way of pulling this information. At some point. I may add more functionality. I will because I would like to automate the process a little more as far as alerting is concerned. Perhaps even add some alerting from a daemon process that will provide a weekly to monthly report for a list of certificates.

    Below is the Git repository for it if anyone is interested.

    I am convinced that Google Cloud Platform training is some of the best that I’ve taken in a long time. They provide just about enough hands-on material with lecture that makes it almost perfect. Given the hands-on lab material it provides outside of the courses. That makes up for it. Some of the courses are all just hands-on labs too. It’s great!

    Finished finally setting up my first VPN tunnel between a FortiGate firewall and Google Cloud Platform. Given that there isn’t a whole lot of data related to the subject online. I thing I’m going to write some notes for it. Stay tuned for more… I intend on jotting down my notes for that and GCP to GCP VPN tunnels.
