Issues with wget authentication

Sean,You are right, my issue is that I did not get this far. I'm still having authentication issues. I cannot use neither wget nor curl, so I have to do everything manually. Looking at wget's auth-no-challenge implementation, it seems all it does is set basic auth headers, which we already d...

Issues with wget authentication

Sean,I am able to read the file listing from NASA CMR, but the lack of the file size in the HEAD request is still a problem. Our generic downloading code looks at the expected file size to make sure the download is not interrupted. I can turn this check off or propagate the known file size from else...

Issues with wget authentication

Sean,

To make sure I get this right - what are CMD concept ids for MODIS Terra and Aqua L3BIN datasets? For example, is this the correct concept id for CHL:
https://search.earthdata.nasa.gov/search/granules?p=C1458149034-OB_DAAC&q=modis%20terra%20l3bin&tl=1565042310!4!!

Issues with wget authentication

Thank you, these URL now work. Last question - if a file has different creation time and modification time, which of them shows up in the cdate field? (Hopefully, modification time?)

Sean,

Yes, crawl-????.googlebot.com sounds right. If it's impossible to unblock it, I'll try CMR.

Issues with wget authentication

I'm able to repeat the request with the exact same headers without issues from my desktop, so I'm kinda stumped. Could you look in nginx's error logs to see if there are any details? The URL I tried was:https://oceandata.sci.gsfc.nasa.gov/api/file_search?search=A2020014.L3m_DAY_CHL_chlor...

Issues with wget authentication

Thanks, Sean. This looks promising, but I'm hitting a weird snag. Using wget on such URLs works fine, but fetching them using our internal system returns a 403 and this:<!DOCTYPE html><html lang="en-US"><head><meta http-equiv="content-type" content="text/html;charset=utf...

Issues with wget authentication

Sean,Thank you, but the problem is I actually can't use neither wget nor curl, as my binaries do not have access to the Internet. Instead, we have an internal system that proxies HTTP requests, and I don't think I'd be able to use plaintext auth there. I was hoping to use this system for...

Issues with wget authentication

Hi,I'm having the same problems as above - wget only works --auth-no-challenge=on, but since this method sends plaintext password, it's not great. LPDAAC downloads (eg, https://e4ftl01.cr.usgs.gov/VIIRS/VNP13A1.001/2016.08.28/VNP13A1.A2016241.h24v06.001.2018162005736.h5) also require authent...
