What solution do you have so that I can get the speed of downloading from a server or uploading to a server on the TCP or UDP protocol, which I do not have access to that server? but I have root access to my server.
For example, I have a server and without access to Google servers to install special programs and only having the site address or the IP of that external server, I want to know the speed of data transfer between my server and that Google server? (Similar to downloading/uploading a file)
My best option is Linux CLI platform and any idea, solution, open source code, program or any solution or suggestion is helpful.
