L1B problems

You aren't doing anything WRONG, just pushing the limits of historical conventions (which didn't allow "." in a username due to legacy usage: "chown user.group ..."; current usage has changed to "chown user:group ..."). Using an ocssw.test user account on macOS ...

PAR data set format

In my lab we run into changes in raw storage format and scaling with netcdf-cf data sets from non-NASA sources.  In all the cases that were brought to my attention, explicit hard coding conversions and rescaling could be removed using current NetCDF libraries, resulting simpler and more robust ...

installing SeaDAS 7.4 fails

I'm sure someone at NASA can explain the difference between the vxx.xxx.xx.xx and vxx.xxx.xx.xxc files, but since mismatches like the one you have are a problem at my site, I'll pass on what I have learned.The NetCDF metadata for V2017124173600.GEO-M_SNPP.nc has:source = "V2017124173600...

Adding an ocssw user will require an admin, but only for a few minutes unless your site's policies require an extensive paperwork exercise for such accounts.

l2bin error

For every forum post like yours there are many other users who just give up and rely on the standard NASA products and most problems encountered by forum users show up sooner of later in our lab. I suggest you set up a new "ocssw" account andt install using only the command-line (the defau...

Better to stick with the default Apple configuration until things are working since that is what most other people will have.  I haven't used homebrew in years, but I recall that the default was to install in a "private" area and create symbolic links under /usr/local.  ...

You can certainly encounter problems with environment settings when mixing shell programs.   There are some security issues with bash: CVE-2016-0634, CVE-2016-7543, CVE-2016-9401, CVE-2017-5932 were just mentioned in Ubuntu Security Notice USN-3294-1, but Apple is slow and doen't alway...

Running the benchmark is helpful when you suspect a problem with your ocssw configuration.    The benchmark failed for me today  (at l1agen) on one El Capitan box after running update_luts.py, but started working after I ran the installer again (install_ocssw.py -v -b v7.4 --aqua)....

Like you, I was having network connection problems when installing the OCSSW Processing System on macOS El Capitan.  After installing, programs were failing with Segmentation fault: 11.   In fact, if $OCSSWROOT/run/var/modis/leapsec.dat is missing, I get:$ l2bin infile=$HOME/ocssw/ben...
