Issues with different servers about speedtest-cli

[maddie]

TCP pings are used as a fallback in the case of ICMP pings are failed, as indicated in the debug log you've posted:

Failed to ping target host: socket: permission denied
Will try TCP ping  <<<<

I presume you're using Linux? Check the following link for the Failed to ping target host: socket: permission denied error:

https://github.com/sparrc/go-ping#note-on-linux-support

If TCP ping fails too, then please check that the pingURL endpoint is working correctly.

And for the unmarshal failed message in your test infrastructure, which backend are you using?

Yes I am on Linux, but as I don't have root access to any of the servers and firewalls are dropping ICMP packets the go-ping modifications cannot be applied.
The unmarshal failed may be ignored as this is due the modifications I made to getIP.php, essentially I removed everything in relation with external lookups to ipinfo service.

I've checked further and the only difference I could find was a trailing new line at the end of empty.php which is used as pingURL. Removing the trailling new line did solve my issue, but I dont have an explanation for this as there should be no difference between

?>

and

?>

I did also switch to librespeed-cli v1.0.6, thanks for returning json output now on STDOUT!

[maddie]

No problem!

I'm not quite sure about how PHP actually works underneath, but if you're interested, you can also try the Go backend :)

Thanks a lot, I'll give the Go backend a try when I host it available to public or when I create a dedicated server for speedtest purpose.
