Connection tracking on low level request
I would like to have a feature to track all connection requested on the proxy (at low level). Currently via Burp it's not possible to have a list of request executed via BURP but not handled correctly.
For example if burp receive a "CONNECT www.pippo.com:7767 HTTP/1.0" and www.pippo.com response with a reset (example TCP RST) you will not be able to see this connection in burp.
It's possible to have a feature to trace all the connections? In my knowledge it's not possible to do it via an extension.
Hi, thank you for your request, could you provide me with some context on your exact requirements? Would you like this to be displayed in the history tab or in a different part of the user interface?
Enabling this logging you will be able to see all the connection requested by the mobile, doesn't matter what happen after.
Which version of Burp are you using? You should encounter a message in the Event log and the Proxy history if there is an issue connecting.
Have you tried using Wireshark to assess this connection issue?
You can reproduce this issue by:
- launch on a system nc -l -p 443
- on the browser (with burp as proxy) go to https://ip of the host
If you don't kill netcat you will not see any error/alert on burp.
There is also others case that will generate the same issue (ex. TCP RST after the connect).
Using wireshark you can see all the CONNECT requests and you can find all the host contacted without problem.
Thanks for the additional information Agazzini.
We’ll investigate and get back to you.
