I was trying to capture xml-rpc calls to a localhost web site using Fiddler. I have yet to see xml rpc traffic.
Specifically, I was using Windows Live Writer which relies on xml-rpc to update blog/story information with underlying metaweblog api. I am able to connect Windows Live Writer to my code/local host but I want to see that traffic in fiddler.
Any ideas as to why I am not seeing it?
The resolution for me was to use the machine name instead of localhost or 127.0.0.1
Once I started using the pc name I was able to view/capture traffic via xmlrpc.

I have a local host webserver c++ code which runs on port 8080 on windows 10.
My first task is to test http requests and responses, and it's done properly with Postman.
But I have another task which is to capture those requests and responses via Wireshark(No other packet sniffing application).
Now, as far as I know it's no possible doing it unless one installs a loopback adapter, so I did it. But Wireshark still doesn't capture packets from and to port 8080.
Can sombedy please tell me what other configurations need to be done so it will be possible?
Probably your best option is to install and use Npcap instead of WinPcap. Be sure to install npcap's loopback adapter and capture on that interface and not on the Microsoft Loopback Adapter interface.
Another very good and simple option (if you're not required to use Wireshark) is to use RawCap instead of Wireshark.
Refer to the Wireshark Loopback capture setup wiki page for more details.
I have a server written on C++ REST SDK.
There's http_listener which listens to "http://localhost:34568".
When I try to send a request in browser or from the client to localhost it works fine and I get the responses from my server. But the point is to use the application in network. And here where the problem comes.
When I try to request the server from the other PC using IP(192.168.1.103:34568) I get "HTTP Error 400. The request hostname is invalid."
I'm aware that that could be some firewall issues but it's turned off. Also I tried to set port rules in brandmauer and it didn't help.
And even more! I got XAMPP running Apache server and when I do the same thing but with (192.168.1.103:80) I do get the response from Apache and have an access.
Anybody had something similar or somebody knows what the problem is about?
Listen to local ip address or to your network name (dns):
"http://xxx.xxx.xxx.xxx:34568" or
"http://your_network_name:34568"
So, if you have multiple network adapters, you can choose which one.
I am writing an application with C++ to connect to my server.
I am using gethostbyname(). It is working fine when I give host name as 'localhost'. but if i try any other site like google.com, it fails.
Can anyone please tell me what could be going wrong.
I can access those websites through browser. Note: I have proxy set up in my browser.
Is thr proxy causing issue with gethostbyname()? if yes, how can I mention proxy in my C++ code?
Based on what you describe in your question, it appears that your machine is on a corporate network that is firewalled off the Internet, all access to the web is via a web proxy, and that your network does not have Internet DNS resolution.
Even if you managed to succeed in resolving an IP address, you will not be able to make an outbound connection, unless your firewall offers a Socks proxy, or an equivalent.
If your intent is to write a client that accesses web sites via HTTP, you will need to use your corporate HTTP proxy to do that. Contact your system administrator for more information.
I want monitor HTTP traffic from BlueStacks so that I can debug web analytics tracking - any idea how?
For example, my application calles my server. I want to know what actual API my application actually called during testing.
I do not see any HTTP requests in Fidller even when using the BlueStacks.
I thought fiddler capture all internet request done by any software.
Actually you can use fiddler. You see, fiddler configures the winINET proxy to go through it (the one used by internet explorer and all other microsoft software, but sometimes even third pary software uses winINET proxy config - that is why some programs just magically work with fiddle). Some programs ignore wininet config completly and have their own method of setting a proxy (like firefox, chrome). And other programs, like bluestacks, have no support for proxy at all.
But you can force BlueStacks to go through the fiddler proxy. A tool which can do that, and which has a tutorial on this, is ProxyCap:
http://www.proxycap.com/bluestacks.html
Just use 127.0.0.1 as server and 8888 as port number in configuration of the proxies in proxycap. You must also add HD-Agent and HD-Frontend executables in the rules, as specified in the last part of the step-by-step guide.
Unfortunately, proxycap is a 30 day trial. You can use free proxifiers out there. Find something that supports http.
http://en.wikipedia.org/wiki/Comparison_of_proxifiers
I did manage to make this work with proxyCap myself and haven't tried anything else yet.
I think this is better for http traffic sniffing than wireshark which is for lower level network sniffing
Use ProxyCap to let Fiddler capture the trafic.
ProxyCap forwards all Bluestack communication to HTTP proxy (in this case our proxy is Fiddler).
The full step-by-step guide, how to redirect the Bluestack application traffic through proxy, is HERE.
Use 127.0.0.1:8888 as proxy address. That is the address of Fiddler on the local computer.
Today I tried Fiddler - ProxyCap - BlueStacks. It didn't work at first. After I added "HD-Plus-Service.exe" everything was Okay. It seems like new bluestacks versions don't use HD-Network.exe? Anyway my program list includes:
HD-Service.exe
HD-Agent.exe
HD-Frontend.exe
HD-Network.exe
HD-Plus-Service.exe
HD-LogRotatorService.exe
In 2019, Fiddler has been updated to support Proxy, just set up your BlueStacks to use Fiddler's proxy and you can capture all HTTP/HTTPS traffic going out from it.
In addition, for latest Bluestacks3 version here are the list of apps you need to add to your both program lists:
HD-Agent.exe ( from "C:\Program Files\Bluestacks\" )
HD-Player.exe ( from "C:\Program Files\Bluestacks\" )
Bluestacks.exe ( from where you installed Bluestacks )
Fiddler has a documentation regarding how to capture traffic of Android devices: https://docs.telerik.com/fiddler/configure-fiddler/tasks/ConfigureForAndroid. You can use the same config for bluestack
I need to monitor a http request and response for web site running on remote web server. The web server makes lot of web service call and would like to trace them.
If the web site was running locally, Fiddler traces every web service call request and provides me with a report. Could someone please help me with how the same is possible
*e.g.
If the web application is running locally and calls two web services fiddler shows the total time on statistics. However, if the web application is running on web server hosted on different web server hosted internally (intranet) and I ran fiddler on my machine, I don't get the statistics for each web service call. All I can see is the total time for the aspx page.*
So question is how (if possible) can I trace the statistics of each web services invoked by web application that's running on different machine and fiddler is running on my machine.
Thanks.
You could always use WireShark http://www.wireshark.org/ to catch all the packets, if you are on the same network as the server, that is.
Say you're running a website on port 80 of a machine named WEBSERVER. You're connecting to the website using Internet Explorer Mobile Edition on a Windows SmartPhone device for which you cannot configure the web proxy. You want to capture the traffic from the phone and the server's response.
0.)Start Fiddler on the WEBSERVER machine, running on the default port of 8888.
1.)Click Tools | Fiddler Options, and ensure the "Allow remote clients to connect" checkbox is checked. Restart if needed.
2.)Choose Rules | Customize Rules.
3.)Inside the OnBeforeRequest handler, add a new line of code:
if (oSession.host.toLowerCase() == "webserver:8888") oSession.host = "webserver:80";
5.) navigate to http://webserver:8888
Requests from the SmartPhone will appear in Fiddler. The requests are forwarded from port 8888 to port 80 where the webserver is running. The responses are sent back through Fiddler to the SmartPhone, which has no idea that the content originally came from port 80.
You can setup Fiddler in your machine and set it as a proxy in the web application you want trace. Easy inside a network, not so easy accross the interwebs.
