install.sh fails internet connection check

[0d0a0c]

The line in the internet connection check

if nc -zw1 example.com 443; then

fails due to the url placeholder example.com

Hello again 0d0a0c,

I don't understand why it fails from your side for "example.com" can you elaborate (some proxies are dropping it?) ?

Have a good day,
Félix.

Salut a tous
I run in an auth-proxied environment (squid).
Commenting out the check_network in the install file got ride of the network check via nc.

Thanks.

This is very odd! It fails the internet connection on my pi. Also on my laptop using the check_connection function in a terminal.

So I tried example.com in the browser and it fails there too. That was when I changed the URL in the code to google.com which works on my pi and on my laptop. I assumed the issue was that example.com was not a real website, just a place holder in the code.

I have now tried it on another laptop, on the same home network and it works from that laptop. Assuming it is something specific to the affected machines.

EDIT:
My issue was fixed by flushing the dns cache on my local machine.

@0d0a0c
Do you have full understanding and control of the the request path - firewalls, dns, dhcp and proxies - inbetween?
Do you have http_proxy or similar in your env?
Is your browser by any chance pulling a pac file?

In my case - my env is correctly set up. NC, being nc in the install.sh - does not honor env. @felixamie: A simple "curl" maybe smoother than nc. Sorry for not providing a patch at this time. Having other issues with the network interfaces et al.
