First time trying to use Wget to access my daymet order. When I enter this suggested text into my command prompt window: wget -r -np -nH --reject "index.html*" -e robots=off https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdaac.ornl.gov%2Forders%2Fa042d92773ba5bca45d87260e3dfbcb6%2F&data=05%7C02%7Crobert.jespersen%40usda.gov%7C88e3814923ee4abd413908dc62f1f66d%7Ced5b36e701ee4ebc867ee03cfa0d4697%7C1%7C0%7C638494038576493490%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=NUonNY5380vXmyMcWcMzmctvL%2BwZuf3p5o4Ma219MEQ%3D&reserved=0

I get this error message:

Any help you can provide would be greatly appreciated,

Hi Gus,
We're looking into your question. Thank you for reaching out.
You are experiencing this problem because our email security tool is re-writing the wget information.

Gus,

The safelinks URL is a result of email clients being extra protective. In this case Microsoft Outlook has changed the URL in your email so it's safer. This is an issue we know about at ORNL DAAC. We are still exploring options to make that recommended URL display correctly in the email. It turns out that is difficult because email clients are really good at identifying URLs.

There are a few things you can do to get the correct URL:

- follow the link in the email to go to the download page then copy/paste the resulting URL
- enter the link in to Office 365's URL decoder here: https://o365atp.com/

In your case, the correct URL is:

Code: Select all

https://daac.ornl.gov/orders/a042d92773ba5bca45d87260e3dfbcb6/
We also have an order help page that explains more about building the wget command: https://daac.ornl.gov/help/order/

Let us know if this helps!

Thank you, that's very informative.

Unfortunately, now I get this:
Resolving daac.ornl.gov... 160.91.19.24
Connecting to daac.ornl.gov|160.91.19.24|:443... connected.
Unable to establish SSL connection

I tried both the link you sent copied directly as well as the translated once from o365atp and got the same error message (link text looks identical). Any thoughts?

I recommend updating the latest version of wget. There are many off-shoots of wget, so I can't say exactly how to do that for your specific case.

Most of the guidance I found about the "Unable to establish SSL connection" error suggests older version of wget are using outdated SSL technology. The posts I found were admittedly older. For example: https://superuser.com/questions/1182465/wget-returning-error-unable-to-establish-ssl-connection

You can also try including

Code: Select all

--no-check-certificate
to see if it will download your data that way.
