How to check proxy settings in Mac?

In a previous post I showed how to use the netcat command to check your proxy settings.

Now I'll show how to do the same thing in macOS.

This is what the results look like in Windows. The command we'll use is: nc -z localhost 8000. Where 8000 is the port the server is listening on, and localhost is your computer's IP address. In macOS this command looks like this: nc -z 127.1 8000 But it doesn't work! Here's why. There are some things that you need to know before you start hacking around with macOS: You can't use your own IP address. You can't use localhost. You have to use 127.1 This might seem odd, but if you're familiar with network protocols you'll see why. The network protocol for most home computers is called TCP/IP. It stands for Transmission Control Protocol and Internet Protocol, which is just a fancy name for a set of rules for how computers should talk to each other.

The most basic of these rules is that every computer should have an IP address. IP stands for Internet Protocol, and is basically a unique number for every device on the internet. The number is usually expressed in the format xxx.xxx, where xxx is a number between 0 and 255.

Every device has a unique IP address, so when you try to use nc -z 127.1 8000 it's telling it to listen on your computer's IP address, which is 127.

Now, your computer can't do this because it doesn't have an IP address! For this reason, you have to use 127.1 instead.

TCP/IP sets up a connection between your computer and other computers on the internet, and every time you try to open a connection it checks to see whether it's already open. If it finds a connection, it gives your computer a new IP address.

How do I check proxy settings in PowerShell?

When running PowerShell, how do I check the proxy settings?

I tried the following but it just tells me the setting is set to auto. Get-NetworkCredential It will be configured to use auto-detect if you don't specify a proxy server. If you want to specify a proxy server then you should use -ProxyServer.10. Format-List
If it returns a value, then that's what you're using. If it returns an empty string then you're not using a proxy server at all.

The Get-NetworkCredential cmdlet doesn't return the proxy server setting because it doesn't need it. It uses the proxy server automatically, so there's no need to tell it.
