I have a python script which triggers a http POST request using standard libraries. I'm trying to view and debug the requests content by capturing in wireshark.
The request is sucesfull because I recieve the correct server response.
In wireshark I listen on all available interfaces but cannot find the request.
I have also tried some filtering options like http filter but the request was still not found.
I have Ubuntu installed and the server host is not localhost
How can I find the request?
You are unable to capture HTTP POST request because you are using Wireshark http filters. Do not filter traffic with HTTP filters, instead of that use website/URL IP address.
I have just tried to filter the traffic with the help of Wireshark and found that I can filter it with the help of IP address.
Refer below link,
https://www.w3schools.com/python/ref_requests_post.asp
Use Filter : "ip.addr==192.229.133.221"
I can filter the packets, but its TCP encrypted traffic and we cannot get additional information without decryption.
Refer below answer, it will help you to find the IP address of your URL.
How to use filters in the wireshark?
If you are not comfortable with it, use “Microsoft Network Monitor” tool. It shows applications name along with IP address and ports.
Once you know the IP address and ports used, you can filter the traffic with the help of Wireshark easily.
Note:- I will suggest instead of "Wireshark" or "Microsoft Network Monitor”, please use fiddler. Refer below link,

I am trying to monitor calls to an API, and I am trying to do so with wireshark. However, I only see low level packets, I want to see the actual http and https requests and responses. Is this possible with wireshark?
You might consider using something besides wireshark for this.
For instance the Burp proxy will allow you to inspect requests and responses between you and the application, as well as pause a request, edit it, then send it on it's way. It really is a great tool for working with web APIs.
I'm trying to get the underlying socket/stream or the IP address from a NSURLConnection as the request starts transmitting a response. I haven't been able to find a way to get the underlying lower level stream from an active request (which would then easily allow me to get the IP information).
The use case for this is to record the exact IP used to a debug log since the hostname in the URL request can return many different IPs from the load balancer.
I recognize that these are higher level APIs than plain sockets and I'm considering doing a parallel DNS resolve for the same hostname as a workaround, but that still doesn't gurantee that the DNS resolution will return the same IP that was used for the request in question.
Thanks in advance for the help!
I am trying to communicate with my hosted server using an Arduino Ethernet shield.
Now the problem is this:
Using a web browser, I can see that calling the URL works fine, but calling the IP address does not. I assume that the hosting provider hosts several different URLs using the same IP address.
How can I make a URL dependent call from within the Arduino libraries? The standard Arduino libraries only require the IP address of my host, not the URL.
You need to ensure the http GET/POST request has the correct Host field.
Here's a sample get request from http://www.w3.org/Protocols/rfc2616/rfc2616-sec5.html
There's a lot of good technical information on this site.
Sample HTTP Get Request:
GET /pub/WWW/TheProject.html HTTP/1.1
Host: www.w3.org
This may require some customization of your code, but should do the trick !!
other options:

I'm working with the API using HTTMultiParty and I'm having trouble capturing the outgoing HTTP requests when I make POSTs. I don't see them at all in wireshark. I am capturing on the wireless adapter (I have no other internet connection) and filtering on
http.host contains "docusign"
but I can't see anything come up. Even with just an HTTP filter, I see nothing new captured while I see a request and response. Why is wireshark unable to view the traffic from my rails app? Note: I can see the request made by my browser to the rails app.
Since it's https traffic, assuming you know the IP address of the server you're talking to, use the filter ip.addr == x.x.x.x and you should see TLS traffic leaving leaving your client.
I presume in the above comments that you mean "ip.dst" because there is no such thing as "tcp.dest" as far as I'm aware.
Slightly old but here's a complete list of filters.
i am watching a video stream from a proprietary app and i want to know the URL it's connecting to. note that in this case, i know the URL that it connects to but am curious how i'd determine it using wireshark.
i have wireshark open and i let it scan for a few seconds. i looked at the results, and all i was able to determine was the url and port of the site that's providing the stream. there's a series of URL parameters that are important as well. is there a way with wireshark to see the whole url that the app is connecting to?
A full URL is the concatenation of 'host' and 'path' ('path' is URI in wireshark's jargon).
The concatenation of these strings usually does not pass on wire - you will not see it in wireshark - and it is not required by HTTP.
Therefore, you have to concatenate them on you own, either manually or using some software as the one proposed by the writer of the lua dissector.
Example:
GET /path HTTP/1.1
Host: www.amazon.com
thus, the full URL is: www.amazon.com/path
There is no such thing as a "whole" url. An application may connect to many servers during it's lifetime.There could be different servers for authentication, configuration, logging, data, etc.
Wireshark is a low-level monitoring tool. You can choose to watch the packets of a specific osi-layer and add filters to limit the output. But I don't think it can aggregate all the incoming connections of a specific application.
Please, check out following custom dissector written in Lua, that helps showing full URL in wireshark HTTP captures
