HTTP Sniffer traffic - http

I'm trying to find out a way (or a tool) to see all http traffic that comes into my WiFi network.
I found Fiddler or HttpDebugger but it only works on the computer I have installed them. Is there any other that works globally? For any computer or mobile device that is connected to my Wifi.
Thanks in advance

Traffic flow with and without VPN?

I was not able to access an open learning website that was working fine earlier with the same Vodafone network.
To troubleshoot this further I have checked it with another network JIO and found that It is working fine.
So, further, I checked with the Vodafone network by connecting VPN and found that It is working as expected. (If I am disconnecting VPN then It's not working).
FYI:
a)Without VPN with Vodafone Network
(base) Shailesh-Yadav:~ shaileshyadaav$ host website_name
;; connection timed out; no servers could be reached
b)after connecting VPN with Vodafone network
shaileshyadaav$ host website_name
www.web_site_name is an alias for spayeeservers.com.
spayeeservers.com has address 134.2XX.XX.XX
spayeeservers.com mail is handled by 0 smtp.secureserver.net.
It'll be very much helpful to understand working if anyone can help me with below question.
1. I am accessing an open website(not having any restriction) and the same is not accessible with the Vodafone network but observe that It's working when I am connected to VPN. So how the traffic is flowing.
2.Any command through which I can understand the destination route(how it is reaching) OR differentiate the flow path(reason for this).
I have checked it by using the traceroute command and found that the traffic is flowing with different routes(hopes) with VPN and without VPN.
So, It means if we are connected to VPN then all the traffic will go through a tunnel and the site is not working without a VPN maybe some restriction from the ISP side.
(but again one doubt which one is better/faster in performance).

vpn not listed in wireshark to analyze packets

I have vpn connection in my laptop. I am able to ping the vpn ip address successfully. I would like to analyze the network traffic and packets to and from vpn.So, I installed sharkwire But I dont see the listing of either VPN Name or the IP Address of VPN in wireshark. Any help?
Wireshark uses WinPcap on Windows, and some third-party VPN software doesn't work with WinPcap and even some standard VPN software might not work with WinPcap. That might be the problem.
You could try installing Npcap and, if Wireshark uses it, that might fix the problem. As its main page says, report problems on Nmap's GitHub issues page.

Ethernet Data Traffic hidden from capture

I have a puzzle I am not able to figure out, I would appreciate any help.
I am connected to a remote desktop using windows default remote desktop utility (Windows 8 locally, Windows 7 remotely).
The remote desktop is not in the same sub-network as my own.
Connection is made through default port 3389. Using Wireshark locally I can confirm the TCP connection being established and the data flow.
Running Wireshark in the remote desktop, I don`t see any flow of data between the two computers.
If I send a ICMP ping from the remote desktop to my computer, it works well and I can see it in Wireshark both remotely as well as locally. But if I send the ICMP ping from my computer to the remote desktop, it fails. I see it leaving my computer through Wireshark, but it never reaches the remote desktop (I don`t see it in Wireshark).
I don't think it is a firewall issue (specially since it can't explain why Wireshark won`t capture the port 3389 RPC flow).
Does anyone have any idea of what might be going on?
I found the main issue.
In Wireshark, turns out it is possible to configure the capture interface with a filter.
To change it, go to: Capture->Interfaces
On the interface being used, stop capturing to enable the Options, there it is possible to configure a capture filter.

Send data/string online to a device connected to the internet

Good Day,
I basically have a laptop connected to the internet with a fixed IP Address. I need to have a way for a server possibly though a PHP script, send data/string to the laptop and it is able to receive it.
Now, if I was within a local network, i could do that. But what if I wanted to send from an external network? Do devices have a particular address that I can access from any internet connection?
Do devices have a particular address that I can access from any
internet connection?
No, it does not, unless you do use external IP for your laptop (doubtfully).
The easiest and fastest solution I could think of is to do the other way round: open TCP or UDP socket on your server and use laptop to connect and request data from the server. Of course, it is not suitable for all scenarios, but in many cases it works. Write more information (what is the purpose of this? What are the requirements and limitations?) so more specific answer may be provided.
OK, to make things easier to explain, let's say:
- Your router's public IP address is 10.10.10.10
- Your laptop's private IP address is 192.168.0.1
- You want to communicate via port 80 (since you mentioned PHP)
What you need to do is configure your router so that it forwards packets destined to 10.10.10.10:80 to 192.168.0.1:80. This is the simplest form of NAT.
Then from anywhere else with an Internet connection, you can send packets to your laptop by sending packets to 10.10.10.10:80.

IOS4 - Send data using UDP socket on Wifi

I am trying to send data using the AsyncUDPSocket class. And I can send data using the iPhone simulator over the wire to another machine that is running a simple C-coded listening server. I can also receive data over the wire using a client connected to the simulator(server). However, when I tried the same over Wifi, using the simulator, I could only send data but not receive any data.
I read on another post, that unicast data makes this possible. How can I acheive this using AsyncUDPSocket?
Thanks,
Angelo.
Ok, I figured this out. A newbie kind of thing, really.
When I set my Mac network preferences to Ethernet, I get an IP for me to communicate. However, when I turn Airport(Wi-Fi for more newbies) ON, and ethernet cable disconnected, I checked my network preferences, and sure enough my IP address was a different one.
Spoke to a friend (an ace in networking) and the thing clicked immediately: On WiFi networks a DHCP server allocates an IP address. This IP address has to be reserved, at the very least, at the DHCP server. Since my IP was not reserved, I had to change the IP address, in my udp_client.c file, recompile and run the client to connect.
BTW, I can now communicate between my iPhone and my PC using my local WiFi (office) network.
For any who might face the same problem, do not be assured that the IP address of your mchine is the same, when you switch from LAN to Wifi, and use the device mostly for WiFi reated testing. :)
