I just changed my VPN and tried to capture the browser traffic in fiddler logs.
I tried by checking the option "Automatically detect settings" (Tools > Winnet Options > LAN Settings)
Also checked the option "Decrypt HTTPs Traffic" (Tools - Options - )
Also Cleared the "Clear Winnet Cache, Cookies, browser cache, temp files" in system.
Can any one tell me how to solve this problem?
I attach my error in the image here, for your reference.
VPN software and firewall clients are common culprits. It’s a known issue, please refer below link,

Some VPN's doesn't allow you to pass traffic for other applications.
If you're professional and using the VPN's provided by Company, ask the company/support team regarding issue. They have their own setup for these type of applications.
Some New VPN's like Z-Scaler will not allow the web traffic to other applications and they're trying to resolve this issue asap. But for temporary solution, they have a kind of setup which we can use to work?
Make sure you tried all the options of fiddler and if it is new VPN, Google it and that VPN may already provided which applications will not work with their VPN's

I am following this instruction http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureForiOS. Everything works until section Set the iOS Device Proxy.
Once I set the proxy on my iPhone, I can't connect to the internet from the phone anymore. Not even accessing the echo page, which I could access before turning on the proxy on the phone. I already installed the root cert on my phone, the makecert add-on on Fiddler
Could someone help with ideas to diagnose the issue here? Thanks,
What might be stopping your iphone from reaching your Fiddler machine on the port specified, usually 8888?
Have you a firewall on the Fiddler machine? You might need to open
the port.
Does your LAN have an automatic redirect to a login page? Ours
does, so I have to disable the proxy on the iphone while I login,
then reenable it.
Does your LAN expose the IPs of cable-connected machines to WIFI
users? Not all do.
Can you browse a simple web page on your Fiddler machine from your
iphone, before starting fiddler or doing any proxy configuration?
You might need to get really serious and install a ping utility on the iphone.
I've been trying to configure a captive portal using DD-wrt and Open-wrt, with my own radius server and I've also tried to configure them using a CSP page (http://worldspot.net).
DD-wrt
My first try was with a TP-LINK WR841N (v7.) and DD-wrt using the web interface. In dd-wrt web interface there is an option in Services -> HotsPot -> ChilliSpot. Here I tried both configurations, using my own server data, and also tried with WorldSpot data, and my issue was the same in both cases:
When I enable Chillispot on the router, I don't get IP assigned, meaning I can't connect to the wifi/lan. It seems the problem is obviusly with the router and It's something like the Chillispot configuration is not working, or the changes are not"applied"
Open-wrt
After some hours trying to make work dd-wrt I think that maybe with open-wrt it was easier to configure, and here I found another problem. After updating my TP-LINK to Open-wrt I realized that I cannot access to the router via WEB, so I have to connect via telnet and ssh to install some packages and make some configurations.
I tried to install "luci" the package for the web gui and I found with some errors:
- First It didn't find the package, and I have to change the /etc/opkg.conf file
- Once I downloaded the package and try to access web I get error uci_load: not found
- Once I fixed the uci package issue, I enable the uhttpd and start it, but when I try to connect via web I get another error "CGI didn't receive any response"
Questions
Someone with more experience than me could point me wich of these softwares is better to have a spot system/captive portal ?
It's possible that in dd-wrt case the configuration of chillispot wasn't applied to the router configuration ?
For open-wrt anyone has same errors with the web interface ?
I've been reading and it seems that it's possible to configurate ChilliSpot via SSH , but the tutorials I found were not very helpfull, anyone can point me to a good tutorial for this ?
I also have a D-Link dir-615 H2 but it seems to be less compatible with open-wrt and dd-wrt than the TP-LINK.
I would be thankfull for any information that can put me in a good direction, thanks!
Some months ago I found a very easy answer for this question about making a captive portal.
The best of this solution is that the router flashing part is very automatized and the Captive Portal configuration is made through a WEB UI very easy to understand and manage
You may also connect through ssh to the router if some software customization is needed, like VLANS
To use this solution your modem should be in this list(At the time the answer is wrote):
Linksys: WRT54G | WRT54GL | WRT54GS
MiniRouter: MR3201A
FonSpot / Fonera (Atheros)
Ubiquiti: Bullet-M | Nano-M | Rocket-M | Airrouter | UniFi | Bullet/Nano/etc/{2/5}
I used this method in several Ubiquiti AirRouters and now it just take me 5 minutes to configure a router for a HotSpot system using FreeRadius.
I tried with FreeRadius installed in a RaspBerry in LAN and also into an VPS through WAN
The steps to flash any of the above routers are:
Download coova-ap.jnlp from here
Open the file with Java Web Start
For Linux systems: sudo javaws coova-ap.jnlp
You have to click Flash CoovaAP and you will see a window like this where you should select your router model:
After the file is downloaded you will see the next window:
Here you should select your network device, usually eth0 (wired) is the best choice, anyways I strongly recommend to click Save firmware to File button to store a backup of the original firmware.
If youre using an Ubiquiti router, before clicking the Start Flashing
you need to:
. If you re using a Ubiquiti device you should put it in TFTP mode by unplugging the POE ethernet cable, and reconnecting it while holding the reset button for 8 seconds. If this doesnt work, you may have to press it for 16 seconds. The LED lights now should flash alternately indicating TFTP mode.
Once you hit Start Flashing and the flash is done, the router will restart and we will be able to access the router using the same Coova software.
Now the Configure CoovaAP button should be clickable and we will see a very fancy interface to configure the router Captive Portal, we will be able to use different HotSpot configurations.
If the button is not clickable make sure the CoovaAP IP is 192.168.1.1
One of the guides that help me most to configure the router using CoovaAP software was HotSpotSystem: Installation CoovaAP guide
On that tutorial you will have more information about some steps and the mainly configuration of the Captive Portal interface. I didn't add the HotSpot part because the question was about which was the best router configuration.
There are some ways to build a captive portal server:
1.
Regarding router compatibility I can only recommend DD-WRT build 22118 or later (coovachilli based dd-wrt).
Following versions are supported: mini_hotspot (broadcom_K26 non-nv60k , non-nv64k!), nokaid, standard, big or mega. Other versions (like mini or micro) don’t contain the hotspot module so they cannot be used for hotspot purposes.
Once you have a such build, you can start a simple Captive Portal with Chillispot.
All what you need is a FreeRadius server & Web Server.
2.
Using OptWARE
Here I used a router Asus RT N16, I've patched it with dd-wrt.v24-18024_NEWD-2_K2.6_mega.bin
The entire tutorial is here.
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
Now that the WP8 Emulator is based on Hyper-V, the old method of using Fiddler to intercept network traffic doesn't work if the network uses IPSEC.
Is there a way to use Fiddler and a WP8 emulator in such a scenario?
Fiddler with exactly the same setup as on WP7 (https://fiddler2.com/fiddler/help/phone.asp) works absolutely fine for me.
You grab the traffic from the host system, so the guest (the WP8 emulator) has to bypass that too.
If it doesn't work let me know, but for me and others I know, it runs without any issues.
I finally found the answer at http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj684580(v=vs.105).aspx
On a corporate domain, the emulator appears as a separate network device that is not joined to the domain. As a result, you may also
have to get an exception from your IT department before the emulator
can connect to services that are running on the domain-joined
development computer.
A network security exception was required.
You will probably have to use something like wireshark which works at a sub-protocol level and can therefore intercept anything.
Note that analysis won't be nearly as easy as it is in Fiddler though. Also, HTTPS connections might be impossible to analyze because of the whole man-in-the-middle attack prevention brought on by the protocol and certificates and such.
I get internet access on the browser but when i run the application, the application doesnt get internet. I have used internet permissions.
Actually the problem is because of proxy settings.
Early there was no internet connectivity on the browser, but later I set the proxy in APN and internet started working on the browser. But the application doesnt get internet.
Any solution for this?
** EDITED Apr 13th 2010 **
To get the proxy working with WebView, you apparently need to call WebView.enablePlatformNotifications()
According to the HttpURLConnection docs (Proxies heading):
Proxies
By default, this class will connect
directly to the origin server. It can
also connect via an HTTP or SOCKS
proxy. To use a proxy, use
URL.openConnection(Proxy) when
creating the connection.
You should be able to enable proxy use by setting the system properties described here, however this may not work on Android - the bug report on Proxy support doesn't go into much detail on where the bug is (e.g. property not set vs property not used)
Proxy use can also be controlled using ProxySelectorRoutePlanner, which is used by AbstractHttpClient.setRoutePlanner. Unfortunately, this means re-writing the httpConnection code to use DefaultHttpClient
Hope this helps,
