disabling utcpole.dat/leapsec.dat update

It is much safer to run install_ocssw.py as a normal user, e.g., without using sudo.  Some linux distros will prevent regular users from completely filling the disk, so when you run out of space you could see a useful error message instead of a crash.   The simplest way to recover is ...

L2 Bin - processing ocean color data

The real documentation is the source code.  In $OCSSWROOT/run/build/src/l2bin/l2bin.c, search for 110 and you will see that when no bins are filled, the output file is removed and ret_status set to 110: printf("total_filled_bins: %d\n", total_filled_bins);    if (total_fille...

Update the ocssw processors failed

I have MacOS El Capitan v 10.11.6 (with the supplemental security update), but your version should work once you have newer openssl support in some python-2.7.   The Apple version pf python-2.7 uses a very old openssl library that does not work with the NASA servers.   Macports o...

Update the ocssw processors failed

Running ./install_ocssw.py --install-dir=$HOME/ocssw --direct-broadcast without the --git-branch=v7.3 resets the branch to "master".    When things aren't working smoothly it is a good idea to add the -v flag for verbose output.  You would have seen messages like "S...

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...
