Discovering the speed of data transfer between my server and another server that I don't have access to

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.

I presume you have nftables or iptables available. the commands below are for iptables.

iptables -N ACCT_OUT #outbound accounting
iptables -n ACCT_IN #inbound accounting
iptables -A FORWARDING --dst <remoteip> -j ACCT_OUT 
iptables -A FORWARDING --src <remoteip> -j ACCT_IN
iptables -A ACCT_IN -p tcp 
iptables -A ACCT_IN -p udp
iptables -A ACCT_IN -p icmp
iptables -A ACCT_OUT -p tcp
iptables -A ACCT_OUT -p udp
iptables -A ACCT_OUT -p icmp

This will count bytes hitting these chains.

iptables -L -n -v -x

This will zero out the counters.

iptables -Z ACCT_OUT
iptables -Z ACCT_IN

This resource provides a much more verbose answer. https://catonmat.net/traffic-accounting-with-iptables

In general, when I type iptables -L -n -v -x, the bytes column shows a very small value compared to what my traffic has passed!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
