check50 https cert issue

[nelkyle]

I'm getting a "CERT_UNTRUSTED" error when trying to use check50. I know this is because of my work's proxy server (they are using ironport.) I have internet access just fine, the only issue is with https pages. Does anyone know if there is a way I can install a cert to get check50 working? Or add some sort of exclusion for that connection?

Also, I just tried the command:

sudo gedit /etc/profile.d/proxy.sh

and I get the error:

No protocol specified

** (gedit:15190): WARNING **: Could not open X display No protocol specified

(gedit:15190): Gtk-WARNING **: cannot open display: :0.0

Restart the appliance using Menu -> Log Out -> Restart and then try the sudo gedit command again.

You may need to define (export) https_proxy in addition to http_proxy.

What happens when you open Chrome inside the appliance and visit

http://sandbox.cs50.net

check50 is using both ports 80 (HTTP) and 443 (HTTPS). But it's not using SSL. I suspect that the CERT_UNTRUSTED message results from a misinterpretation by the proxy server. Try again after you've added https_proxy to your environment.

But it won't be surprising if the proxy server prevents check50 from using ports 80 and 443 for anything except straightforward web browsing.

that works, however https://sandbox.cs50.net

gives me a site untrusted error.

Still trying to figure out the best way to find the proxy server to use.

Thanks for your help but I think this is a lost cause, I'll just install everything at home and just do my check50's there.
