Hi,

I wanted to say a huge thank you for creating and maintaining this docker image, it is fantastic!

Can I suggest adding the dnsleaktest.sh script into your image (and store it in the data folder) from here https://github.com/macvk/dnsleaktest as this test, at least gives peace of mind that DNS is not leaking when connected to the VPN.

Note that the script requires curl, so you will need to "apk add curl" to your image for it to work.

This could then be added to your README as another test to Verify Functionality: docker exec -it openvpn-client /data/dnsleaktest.sh

Thanks again for your excellent work.

I won't add that particular one. However, I'm not against the idea generally.

If you look at that script, you can see that it's just running a curl command and parsing the output. Since wget is already in the image, you should just use it.

docker exec openvpn-client wget -qO - "https://bash.ws/dnsleak/test/$(shuf -i 1000000-9999999 -n 1)?txt"

Ah yes I see, thanks for looking at this and for the instructions to use wget. I’ll use that going forwards.
