Ruling out assymetric route (first)?

I have a CentOS7 system with OpenSSL 1.0.1e-fips 11 Feb 2013 which works intermittently, as do  other systems here (Bedford Institute of Oceanography in Nova Scotia).  I see intermittent "no route to host" errors and "host not responding in web browsers.  Our IT people ...

Raster Export as GeoTIFF, floating point vs integer

You don't provide enough detail for someone to reproduce exactly what you have done, but I can tell you that GeoTIFF doesn't support scale and offset transformations.  A good guess is to try the values from the NetCDF files.  One way to check this guess is to use the Statistics too...

Ruling out assymetric route (first)?

It may be helpful to provide tcptraceroute results, but this usually needs "sudo".  Use port 443 for https, as in:$ sudo tcptraceroute oceandata.sci.gsfc.nasa.gov 443Selected device wlan0, address xx.xxx.xx.xx, port 26005 for outgoing packetsTracing the path to oceandata.sci.gsfc.nasa...

New thread on manual update of OCSSW processors

It seems homebrew is not building openssl correctly.  Trying to fix such issues after a package is installed is something for experts, and is more of a quick fix.  Unless homebrew fixes the problem, the workarounds will have to redone for each update.  Anaconda Python (binary packages...

New thread on manual update of OCSSW processors

@jgallenWhich MacOS version? How did you install the version of python in /usr/local/bin?  If you used homebrew on El Capitan then your python may be showing the OpenSSL version from the homebrew OpenSSL headers but actually linked to the (insecure, deprecated) Apple library.  See Installi...

New thread on manual update of OCSSW processors

You aren't doing anything silly at all -- if anyone is being silly it is Apple letting people thing they care about security and then shipping python with an obsolete openssl library.1) Does the python script work with python 3.5.2 or does it need 2.7.8?The OCSSW scripts need a python 2.7, but a...

@Swathy -- I just had the same problem so it may have been an internet hiccup.  You can try running update_luts.py manually.   I don't think the install_ocssw.py script does anything more after "Python version acceptable" than run update_luts.py for each requested sensor.

Many open source software providers have moved away from tarballs in favour of direct access to version control repos.  This has important advantages: a) less work for software providers (so they can focus on improving the software), b) users can pull particular versions, and c) lower network c...

NASA is not the only organization moving to https or beefing up crypto protocols for https.  Many sites will be adopting the Mozilla Modern recommendations so if there are problems with NASA now there will be problems with others sites in the future.   It would be helpful to have some...

Connections to oceandata.sci.gsfc.nasa.gov timing out!

Wget 1.13.4 is quite old, so there is a good chance it was built an old version of openssl or gnutls that lacks (Mozilla Modern) crypto support required with many sites that enforce https. The two most common crypto libraries on linux are openssl and gnutls, so it might be useful to check that ciphe...
