Info

From localhost to instant DNSOften, especially when working with other people or when developing integrations with onlineservices, we have to make our computer accessible from the Internet. This information could beobtained from our trusty router, but wouldn't it be easier if we just had a tool that makes our computerport publicly accessible?Luckily for us there is such a tool!Meet ngrok, the versatile one line command that makes you forget about router configuration andcontinuous redeploys. Ngrok is a simple tool that exposes a port from our computer to a uniquedomain name publicly available on the Internet.How does it do it?Well, let's see it in action!Go to the website, click on the Download button, and choose your destiny. In our case, our destiny isthe Linux package in 64-bit. Next, go to the terminal, unzip the file, and copy its contents to the binfolder:cd downloadsunzip ngrok.zipmv ngrok ~/bin
Now do a rehash and type the following:ngrok http 80We can see that port forwarding for ports 80 and 443 is running on our local 80 port, at a customngrok subdomain name. We can also see the region of the server, which by default is located in theUS. If we are in a different region we can set this with the following:ngrok http 80 --region euThe ngrok server is located in Europe. In order to test our ngrok server, let's use our trusty Pythonserver to show a simple HTML page:python -m SimpleHTTPServer
