![]() Open a new terminal to start CRDB: cockroach.exe start -insecure Step 3: Prepare the Database and create our schemaīefore we do anything else, we’ll need to ensure CRDB is running and start a SQL session so we can issue commands. Further, we are able to use NPoco as a micro-ORM for the same reason: it has Postgres support built in. Since CockroachDB is compatible with PostgreSQL, we are able to use Npgsql as a data provider, and don’t have to worry about one built specifically for CRDB. NET Core Web API project in Visual Studio. NET Core Web API Projectįirst, we’ll walk through the normal initial steps of creating a new. I’ll be borrowing heavily from the code in that article to make a connection to our database. It’s not required, but you may also want to read through this “ Build a C# App w/ CRDB ” article as well. We’ll use a slightly different schema than used in that tutorial, but if you’ve never used CRDB before it’s a good place to start. Prerequisites: If you don’t already have a running version of CRDB, follow this tutorial by Cockroach Labs to get started. If you’d rather use something other than NPoco-go ahead! Just note that this post is specific to NPoco and CockroachDB.Īlright, let’s jump into the tutorial. Granted, a lot of improvements have been made with the release of Entity Framework Core, but in that time I’d already grown accustomed to NPoco. Then later versions had some reported performance issues, hence there was a push to third-party libraries. For a while EntityFramework was the go-to data framework for C#. hopefully.leading to quicker app prototypingĬhoosing an ORM (or micro-ORM for that matter) is almost never an objective decision.Improved code readability around queries.Also, in my opinion, it helps the data access code become predictable. I’ll admit my immediate reasoning for using an ORM because I commonly rely on one when interfacing with a SQL-compliant database. OSINT tooling/consumption : Python + Flask, metagoofil, recon-ng, FOCA, and nmap. ![]() “Data flow” : CockroachDB, Apache Kafka.Back-end : C#/.NET Core, SignalR, Rx.NET, NPoco.NET Core, NPoco, and CRDB.Ĭurrently, this is the (loose) tech stack of the larger OSINT project: So, below I’ll be covering how I connected. I’m electing to use the NPoco micro-ORM to make the connection a little easier. NET Core to this new distributed database I had never seen before. Together, these two technologies could give me distributed message queue connected to a persistent data store!īeing most of my software engineering experience has been in C#, I was left with a question of how to move data from. However, a studious suggestion from a professional mentor turned me to Apache Kafka and CockroachDB to handle the data storage and distribution concern of the project. Previous attempts at designing such a system left me with scalability issues. For example: synchronize WiFi signals with perimeter photos. To take this idea a step further, if such a system was designed to be distributed across IoT hardware it could introduce new possibilities for physical network pentests. I thought introducing some level of automation could make this “gather and organize” process easier (some clever modeling could alleviate that). Differing data formats make it difficult to relate and analyze the data sets from the tools.The lack of organization caused writing reports to be just as tedious as performing the test.However, I quickly learned these tools returned disparate data sets and formats. When I first learned about network penetration testing I was enamored with the reconnaissance tools available for gathering data. In this post, I'll give a w alkthrough of how I'm building the system, and how these connections work, so you can use them too. For this system, I’ll be using CockroachDB for its distributed nature, and connecting it to a. Thanks for the pointer - while you were writing i managed to find the solution by trial and error.Hi, I’m Darrien, and I’m building a distributed, near- real time, “OSINT data reconnaissance” system.
