Where I work I need to test payment processes (Elavon, SagePay etc)

I need to open a port on my router and forward it to my machine so that the redirect URL for the payment will work correctly.

The port on the router is only open and forwarding when I need to test payment stuff.

 

When I have the port open and am using Fiddler to test I notice that I get inbound requests showing from google.pl and a few others which seem to use my computer to perform searches etc.

 

How can I get Fiddler to stop allowing these requests? As I'm currently having to constantly open and close Fiddler so that only running when absolutely needed.

Hello,

 

I keep receiving the following error each time I open Fiddler:

I am sure you guys are busy testing the beta version of Fiddler for the Mac.  I am super excited to see this work moving forward.  Unfortunately the number one feature I use these days does not work on the beta version for the Mac, which is Remote connections.  Each time I try to select to Allow remote connections it crashes. :-(

Is this a known issue?  If so I hope it can be addressed soon as without this the usage of Fiddler on the Mac is dead on arrival for me.

 

So I looked up a video on bypassing HWID authentication and it looks like something like this. Take a look at the screenshot below:

This is what I'm supposed to get when someone uses Fiddler to receive the authenticating packets(?) but all I get is this when I'm using Fiddler I don't get anything:

Do you guys have any clue as to how to solve this problem? Was this an impossible task from the beginning because I would first have to infiltrate their servers first? A in this case, a .lua script is injected into league of legends.exe and that .lua is asking for an HWID authentication from their server at access.sx-auth.me... Someone please help me! I've been trying to solve this for the past four days and I just can't seem to do it. At least tell me it's impossible so I can stop hurting myself lmao. Thanks.

HI, I came across the blog article below and I'm curious if there are any examples on how to use an existing cert vs the default "fiddler DO NOT TRUST".

Hello Eric,

I have a quick question.
I have made a c# program that downloads files from any site and saves them (if, and only if the content type of the file contains the word "torrent").

One site in particular allows me to do this. However after I have downloaded "X" number of files, my ip is prevented from downloading any more for a 24 hour period.

The temporary (or manual) solution to this is to disconnect and reconnect my internet (therefore getting a new ip address).

However this is not feasible, as I need this functionality inside a C# winforms app.

Can FiddlerCore change my actual internet ip address (without me disconnecting and reconnecting) just before sending an HttpWebRequest to a new download link (ie generate a new one) ?
(or even better) Can it spoof my ip address ? And if so,would it require FiddlerCore to setup as a proxy ?

Thanks

Hendrik

I am trying to understand how the installed version of my Fiddler on my server has created a dependency where if Fiddler is not running/memory resident my .Net application will not pass traffic via http/https.

We really like the product however want to be sure we can control access to our business critical applications without relying on 3rd part apps.  can someone please help me to understand what setting/where this can be changed so IE works wit or without Fiddler running? I think it has to do with the Web Session Manipulation feature, i have tried to replicate the issue however have not been able to. server OS 2008r2.

Initially I thought this was a bug from the Jetty HttpClient Java library, after I filled out a bug report and things were checked into we found out that Fiddler proxy replies to the CONNECT with a response that contains Connection: close.

I tried to capture the same traffic in Charles and it's working with no issues. Here is the link to my Jetty bug report page.

https://github.com/eclipse/jetty.project/issues/973#issuecomment-250836144

 

Here is the link to the log file  http://dropcanvas.com/11ltw

 

Any idea why it's working fine in Charles but not in Fiddler?

Hi Eric,
        I'm using fiddler with selenium(firefox) and configured firefox using details provided at http://blogs.telerik.com/fiddler/posts/13-04-01/configuring-firefox-for-fiddler.

Hi,
I'm using fiddler to intercept the calls from my web browser to a local server from about two months and it is simply AMAZING so thank you for this great tool.

Now I would like to use it in a manner a bit more complex. I would like to intercept the calls (XML/SOAP) form my local webserver (WebLogic) to a remote one of which obviously I know the specific IP and port.

I have some problem to configure the proxy used by Weblogic, in fact it seems that the standard manner doesn't work. Maybe it is a my fault (I'm not an expert in this field) or maybe the weblogic domain, configured by my company, has some particular restriction that prevent me to use a proxy.

I guess if there is a manner to redirect to fiddler all the outgoing request to a specific address on a specific port ad using an OS configuration instead of a local server configuration. I mean, when windows detects an outgoing connection to a specific remote address and port it automatically redirect (transparently) it to another, in this case to fiddler.

Is there an easy way to obtain this behaviour?
Thanks in advance.

Best regards,
