I have a Linux ubuntu VM where i ran a simple k6 test
import http from 'k6/http';
import { sleep } from 'k6';
export default function () {
http.get('https://test.k6.io');
sleep(1);
}
using the command: k6 run test.js --vus 10 --duration 30s
everything is working fine, i added another network interface to this machine and tried to run k6 and use the new interface using the command: k6 run test.js --vus 10 --duration 30s --local-ips=10.0.0.6,10.0.0.7
Now there are some requests failing with this error error="Get \"https://test.k6.io\": dial: i/o timeout"
I’m running a very small number of vus so i don’t see why this is happening!
The same issue is happening on another Linux VM targeting another URL.
I’m using k6 v0.42.0, OS: Ubuntu 20_04-lts-gen2
Anyone faced this issue before??
Hi @mohamed.sengab
Welcome to the community forums
Can you run the tests separately on both interfaces (the initial one that works and the new interface)?
k6 run test.js --vus 10 --duration 30s --local-ips=10.0.0.6
k6 run test.js --vus 10 --duration 30s --local-ips=10.0.0.7
Is it only one of the interfaces causing the issues? Or both?
Have you tried runing a curl https://test.k6.io
forcing the requests to use each network interface? It will tell us if this is a k6 issue or an OS issue.
Based on the error i/o timeout
, one possible cause is that the new interface can’t reach the test endpoint https://test.k6.io. If curl
works but not k6
, I would run k6 with http debug and we can have a look at the logs.
Let me know the results, and we’ll take it from there.
Cheers!
It seems the new interface has a problem, I tried your suggestion, and it seems curl is throwing error as well ( No route to host) so it seems it’s an OS issue.
Thanks for your help.

Thanks for getting back @mohamed.sengab. Let us know if once curl
works you still see issues and we’d look into it.
Have a nice day!
