Launching and closing Fiddler on Mac prompts for admin authN as it tries to configure the network(WiFi adapter in my case.)

I assume it's doing this to set the proxy. Does anyone know how to give Fiddler rights to make these changes whenever necessary, without the authN prompt?

Thanks

What I am wanting to achieve I think can be done with Fiddler Core, but I am not really a developer, I know enough to modify code and compile it but not to start from scratch.

This is what I want to achieve, I want to listen for a specific URL and POST value, then change the response (which I can do in Fiddler no problem), I want to then compile these settings into a standalone exe with no user interface or options, so i can simply doubel click and have it work on any pc. Since this would seem like a fairly standard use of Fiddlercore, is there a sample project I can download to start me off?

Slightly off topic to the above, rather than wait for the response from the server, can I just respond automatically (maybe add some latency first) and drop the real response if/when it comes?

 

thanks!

Hi,

 

I'm trying to use Fiddler Everywhere on macOS Mojave (10.14.4) and the proxy does not appear to enable after clicking the Capture button.  When I initially installed Fiddler and opened it, I was prompted for my password (but it still did not appear to be capturing any networking traffic).  I also got the password prompt the first time I closed the app.

 

I have since re-opened the app a few times and tried to click the Capture button, but nothing happens.  I also no longer ever get any password prompts (either on app open/close/capture button click).  I've tried to uninstall + reinstall the app as well with no change in behavior.

 

I also tried to run the app using sudo (using the following command):
sudo /Applications/Progress\ Telerik\ Fiddler.app/Contents/MacOS/Progress\ Telerik\ Fiddler

 

Please find the logs (electon.log and netcore.log) attached.

 

Any idea what might be going wrong?

Thanks

I'd like to be able to decode/inspect websocket messages (messages are 20-byte binary) so that each message can appear in a human readable way.  We basically just want to extend/add a custom websocket inspector which will show the selected message after it's been custom "decoded".  I have purchased Debugging with Fiddler Second Edition, but don't see any guidance for implementing a custom Websockets inspector.

Any guidance would be greatly appreciated!

Thanks!

Jim

When connecting my phone to fiddler, I am able to receive traffic. However, which host do I select to filter so fiddler only shows traffic from my phone? Both AppleDeviceService and YourPhone did not work for me.

Reinstalling without keeping settings did not help. I'm guessing I have something really huge/corrupted in the Composer history. Which file / registry key should I delete?

Thanks!

I installed the Fiddler on the Mac.

Following the instructions, when I enter

mono Fiddler.exe

I get the following error message:

-bash: mono: command not found

 

Any ideas?

Thanks,

I have a single ADFS server that is part of an Active Directory domain.  I'm having an issue with a Federated application and have turned to Fiddler to troubleshoot (as I have done in the past) and all of a sudden I'm seeing a strange issue that wasn't happening before.

I'm using fiddler on an administration desktop, so I log on with an admin account, this means when I try to use SSO for a federated app, when I hit ADFS it prompt for authentication.  Normally, great no problem, I put in my normal username / password (not the admin account I'm logged on with) it authenticates and off I go to the federated app.  This has been working fine for sometime but then recently its started to fail. It never accepts my username / password, just keeps 401, 401, 401, prompting me for username / password again and again.

I know my username / password are fine as I use them every day to log onto my desktop AND it only fails when I have fiddler open. If I close fiddler, I get prompted, enter my creds and it works fine.

It also doesn't matter what browser I use.

Does anyone know what this is? Or know how I can troubleshoot it / gather more info?

 

Patrick
