不同界面上的 Speedtest-cli

Question

I have eth0, eth1 and wlan0 connected to my Raspberry Pi. I would like to measure the internet speed of the different interface, in this case - eth1. It works well for eth0 (192.168.1.21), but I get an error if I try to use a different interface, in this case, eth1 (192.168.8.100).

I have read Speedtest python API documentation and mostly copied code from there. I have also tried to search before posting on StackOverflow.

source = "192.168.8.100" #eth1
s = speedtest.Speedtest(source_address=source)
s.get_servers()
s.get_best_server()
s.download()
s.upload()
res = s.results.dict()
download = res["download"]
upload = res["upload"]
ping = round(res["ping"])
print(download, upload, ping)

EDIT: This is the error:

I'm new to speedtest-cli and this post has answered my question on how to use a different interface. So, thanks for that :-)

It's a bit of a guess, but your problem might be due to network routing. Can you ping an external host through both interfaces:

ping -I eth0 google.com
ping -I eth1 google.com

If eth1 times out, then you probably need to update your network routing entries.

ip route
