Terraform is an open-source software tool for Infrastructure as Code (IaC). The tool helps users to define and provision a cloud infrastructure with code. This guide will guide you on how to install Terraform on Linux.
You can either install Terraform from pre-compiled binary or you can also compile it from source and that this guide will help you with installing it from source.
The first step is to clone Terraforms repository from github. I prefer to install all my tools to /opt so thats what I do here but you can download to the location you want.
git clone https://github.com/hashicorp/terraform.git
Next we need to move into the terraform folder and compile the binary, to do this you will need to have golang installed, if you don’t have it already you can follow my guide on how to install Golang.
The last step that I recommend you to do is to make sure that terraform is available in your PATH environmental variable.
First check view your PATH with
Now we just need to move the terraform binary to one of the locations, I choose /usr/local/bin
mv /opt/terraform /usr/local/bin/
Now you have terraform installed. You can verify that is correctly installed by running:
The last thing I will recommend you to do is to enable tab completion so you can auto complete your terraform commands. You can do it by running the following command.
That’s it. Now you are ready to use this awesome IaC-tool. If you are interested in taking the Terraform Associate certification I recommend you to read my review of the exam.

This post is about httprobewhich is a tool for quickly probing for active http and https servers. If you have a list with subdomains you can quickly check which are active by using this tool. Httprobe is available on Github and the tool was created by Tom Hudson (@tomnomnom on Twitter).
2. Download ‘httprobe’ by running go get -u github.com/tomnomnom/httprobe
3. If you used my guide to install Go you can now find ‘httprobe’ at: /root/go-workspace/bin/assetfinder
Basic usage: To use httprobe you need to print out your domains and pipe them to httprobe. In the example below we are are using cat to read the data from domains.txt and gives its content as output to httprobe. cat domains.txt | httprobe
Adding extra ports: By default httprobe is probing for http on port 80 and https on port 443. We can add other ports by using the ‘-p’ parameter. cat domains.txt | httprobe -p http:8080 -p https:8443
Skip default ports and only probe for defined ports: By adding ‘-s’ parameter the default ports will be ignored. cat domains.txt | httprobe -s -p http:8080 -p https:8443
Specify a timeout: If you know that the response time on the target server might be high you can specify a custom timeout by using the ‘-t’ parameter. The time is configured in milliseconds. cat domains.txt | httprobe -t 10000
Combine with other tools: You can combine ‘httprobe’ with other tools such as ‘assetfinder’. If you don’t know about assetfinder you can read my earlier post that helps you getting started with assetfinder.
One example on how you can chain assetfinder with httprobe. assetfinder --subs-only yahoo.com | httprobe -s -p http:80 In the example we first searched for subdomains at yahoo.com and piped the result to httprobe to find out which of the subdomains that were listening on port 80.
