How to see the proxy settings on windows?

问题:

Our work laptops are configured to use proxy to access external sites and I don't have access to see the proxy information. All our applications like IDEs are configured to use system proxy. Is there a way I can check the proxy settings; For example, on chrome or command prompt or any other ways?

回答1:

It's possible to view proxy settings in Google Chrome:

chrome://net-internals/#proxy

Enter this in the address bar of Chrome.

回答2:

You can use a tool called: NETSH

To view your system proxy information via command line:

netsh.exe winhttp show proxy

Another way to view it is to open IE, then click on the "gear" icon, then Internet options -> Connections tab -> click on LAN settings

Other 4 methods:

1. From Internet Options (but without opening Internet Explorer)

   Start > Control Panel > Network and Internet > Internet Options > Connections tab > LAN Settings

2. From Registry Editor

   • Press Start + R
   • Type regedit
   • Go to HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Internet Settings
   • There are some entries related to proxy - probably ProxyServer is what you need to open (double-click) if you want to take its value (data)

3. Using PowerShell

   Get-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' | findstr ProxyServer
   

   Output:

   ProxyServer               : proxyname:port
   

4. Mozilla Firefox

   Type the following in your browser:

   about:preferences#advanced
   

   Go to Network > (in the Connection section) Settings...

You can figure out which proxy server you're using by accessing some websites with a browser and then running the DOS command:

netstat

and you'll see some connections in the Foreign Address column on port 80 or 8080 (common proxy server ports). Ideally you will be able to identify the proxy server by its naming convention.
