A blog about curiosity being a good habit
You’ve written a variety of .NET apps and are running into problems connecting to a third party site using .NET as the client creating outbound requests. This post is not about configuring your server to receive requests using TLS 1.1, and higher. If you are looking for configuring IIS, etc, to meet PCI DSS or other security… Continue reading Enable outbound TLS 1.1 and 1.2 on Windows Server
It’s been a long time since I have played with the Naze 32 and GPS. Not only have I been running Rev 5 (yeah, I am far behind the ball after the last couple of years), but I went to the dark side and got a 3D Robotics Iris+ and, recently, a DJI Phantom 4.… Continue reading Naze32 Rev 6 Configuration for UBLOX NEO-6M GPS
PCI DSS 3.1 can be a bear, especially when you’re running a variety of Microsoft Windows Servers, particularly Windows 2008 R2 (links to support cycle). If you turned off TLS 1.0 you could potentially lock yourself out of RDP, forcing you to physically connect to the machine. If you were running it on a Hyper… Continue reading How to disable TLS 1.0 without breaking RDP
I’ve seen a thousand posts looking for information on the 3D Robotics Iris+ motors and propellers. Hopefully this can be used as a reference. T-Motors or Tiger Motors are the manufacturers of both the stock motors and the propellers. Note: TLDR? Links at the bottom for buying. Note: a lot of people tend to think of drones… Continue reading 3D Robotics Iris+ Plus Motors and Propellers
Here’s a quick how-to on assigning a static IP address to your Raspberry Pi 3.You’ve got your Raspberry Pi 3 (this is for Pi 3 only as far as I am concerned) connected to your local network via WiFi using IPv4. I did this by connecting a mouse, keyboard, and monitor, then using the Desktop to add… Continue reading Raspberry Pi 3 Static IP WiFi Configuration
Go to the directory (or just add the dir to the path) # sudo find ./ -type d -ls To output it to a file: # sudo find ./ -type d -ls > somefilename.txt Another good reference: http://www.tecmint.com/35-practical-examples-of-linux-find-command/ Of course, there are other ways: # sudo find / -type f -perm 0777 # sudo find /… Continue reading Linux – use find to output directories recursively with permissions
I’ll keep adding some good reference material here for checking Linux connections from the command line: TCPDUMP yum install tcpdump See all port 25 connections tcpdump -n dst port 25 tcpdump -n dst host * port 25 tcpdump -n dst host any port 25 tcpdump -i eth1 tcp port 25 Apachetop Go to the link… Continue reading Linux network status cheat sheet
MSSQL_CONNECT and MSSQL in PHP on Linux You’ve yum installed php-mssql and you’re still tearing your hair out because you can’t connect to MSSQL from Linux. In this case it’s CentOS 6.7 with PHP 5.6.23 and Apache 2.2.15. You’re using mssql_connect in a basic test script like this one: <?php #################################### # PHP error handling for… Continue reading Accessing MSSQL from Linux using PHP MSSQL_CONNECT
Getting this error when trying to use ColdFusion CFHTTP to connect to a site using Let’s Encrypt? I/O Exception: sun.security.validator.ValidatorException: PKIX path building failed: java.security.cert.CertPathBuilderException: Could not build a validated path. You need to add their trust chain to you JRE. I’m lazy and don’t touch Java too much so I always have to look up… Continue reading Add Let’s Encrypt Trust Certificates to Cold Fusion on Windows
This drove me absolutely nuts. I recently installed CentOS 7 with the typical LAMP configuration. Also, I know. I shouldn’t be using root. I am because it doesn’t matter in this case – it’s not a production machine. I installed MySQL 5.5 and ran the secure installation (mysql_secure_installation). I made sure selinux and firewalld were… Continue reading root can’t connect remotely to MySQL 5.5
