Use https for URL to GMT data server

[PaulWessel]

Run the encrypted service. Please test from outside hawaii.edu to make sure there are no side-effects since I cannot do it.

Does it work for you? This is what I got:

$ gmt which -Gl @AFR.nc
gmtwhich [ERROR]: Unable to down file https://oceania.generic-mapping-tools.org/gmt_md5_server.txt
gmtwhich [ERROR]: Libcurl Error: Couldn't connect to server
gmtwhich [ERROR]: Libcurl Error: Couldn't connect to server
gmtwhich [ERROR]: File AFR.nc not found!

[PaulWessel]

I cannot test until I go home. The libcurl function may need an extra setting to do this, perhaps?

[seisman]

I don't think it's libcurl settings. You can try visit the URL via you browser. http:https://oceania.generic-mapping-tools.org is redirected to http:https://www.soest.hawaii.edu/gmt/data/, with a 403 forbidden code. But https://oceania.generic-mapping-tools.org cannot be reached. Maybe https isn't enabled by the DNS provider?

[PaulWessel]

Try in a few minutes. The DNS services forwards

oceania.generic-mapping-tools.org to https://www.soest.hawaii.edu/gmt/data

now (it was http). So not sure what happens if you try http. I guess rc4 will have http so it may break? But from the entry above there is no left-side http or https I can set.

[seisman]

Not working for me now. I'll test it later. I believe it's possible to have both http and https. Just like https://www.generic-mapping-tools.org and http:https://www.generic-mapping-tools.org.

[seisman]

I still cannot visit the https URL now.

[PaulWessel]

I just now changed it back to http:

[PaulWessel]

So the GMT server supports either one of course (I remove the local rays_11.txt between each try):

gmt set GMT_DATA_SERVER http:https://www.soest.hawaii.edu/gmt/data
gmt which -Gc @rays_11.txt -Vd
gmt set GMT_DATA_SERVER https://www.soest.hawaii.edu/gmt/data
gmt which -Gc @rays_11.txt -Vd

But doing the same with oceania fails, only http works.

[PaulWessel]

Any thoughts on this @leouieda?

[PaulWessel]

Closing this since does not work for https.

[leouieda]

@PaulWessel I think it's a good idea to do https whenever possible. I'm sure SOEST IT can setup SSL for the data server.
