Wireshark | FreeRDP Wireshark RDP Protocol Analyzer | Learning library

I am currently trying to connect to an AWS REST API which requires at least TLS v1.2. The documentation stats that clients must also support cipher suites with perfect forward secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE).

When sending a GET request using the HttpClient, the connection simply times out. I have set the TLS version explicitely to TLSv1.2 like this:

Summary:
While capturing USB traffic with wireshark, I see that devices enumerate properly when plugged in, but I never see the USB address getting assigned by the host.

Details:
I have tried this on both Windows 10 and Linux, and on several types of USB devices.
I plug in a device, and capture the USB traffic using Wireshark. I expect to see a Setup transaction, with the data packet containing bRequest = 0x05 (SET_ADDRESS) and the wValue word containing the address to be assigned. But I never see this. The wireshark capture does show the other traffic I expect, like "GET DESCRIPTOR" request and response for the device, but no SET_ADDRESS. The simplest device I have is a USB 1.1 mouse, and the wireshark capture (summary lines only) is below.

I have this code to send multicast messages to a group. There are no errors while running the program but when I monitor packets in Wireshark the ethernet destination of my packets are of my default gateway instead of something like 01-00-5e-xx-xx-xx

The code:

we are currently working with a cloud product that uses JSCH internally to connect to external sftp sources. Im investigating an connection reset exception that we are getting when trying to connect to azure sftp.

Using wireshark i determined that the problem occurs after we send the Client: Key Exchange Init. Establishing the same connection with filezilla we dont have this issue.

comparing the packages from jsch and filezilla i didn't see an obivious issue, but im not an expert on the ssh protocol. im gonna post both requests below if somebody could give me any pointers it would be greatly appreciated.

Request with JSCH (not working)

Request with Filezilla (working)

Response with Filezilla (working)

See below for the log output:

Could you explain the "weird" behaviour? I'm running netcat on Linux, as a UDP echo server:

I'm trying to send https web requests with Asio and OpenSSL. My code is working fine on most of the sites I tried it on, but on some others, I get an error during the handshake handshake: wrong version number (SSL routines, ssl3_get_record).

I've found some people having this issue because they were behind proxies or because they tried to connect to port 80 instead of port 443, but this is not the case here (as far as I know) because the exact same code (see below for minimal example) works for most of the sites I tried it on.

I've tried to check with wireshark to see if I could spot the difference between a case with and one without the error. Here what I found:

• when it works, TLSv1.2 or 1.3 is used, when it doesn't, it's TLSv1
• when it doesn't work, the DNS query shows a cloudfront cname redirection, but the endpoint used for the socket matches the redirection

Based on these observations, I know my code is capable of using TLSv1.3, and I thought that using TLSv1 was the issue. So I tried to force asio to use a version > 1 for TLS with asio::ssl::context::tlsv13_client when creating the context, or by adding asio::ssl::context::no_tlsv1 to set_options, but wireshark still showed that a TLSv1 protocol was used.

For the second point, I'm not too familiar with web stuff, so I'm not sure what conclusion I can make about that, or even if it's relevant to the issue.

Minimal working example:

If set up a program with boost asio. Broadcasts are working fine, if only one network interface is present. However, if there are more network interfaces each broadcast is being sent on one interface only. The interface changes randomly. As observed by wireshark.

I'd expect each broadcast to go out on every interface.

Who's wrong? Me, boost or my understanding of how to use boost. Well, I'm aware, that the latter is the most probable :).

And how can I get the expected behavior.

I have a UDP sender program here:

I want to create a named pipe ("mkfifo") with .net6 in Linux.

Using the class NamedPipeServerStream doesn't help me as it creates a socket file instead of a pipe.

This creates a socket :
