We're having several issues with data downloading, and now, running SeaDAS. I tried patching for the https switchover, but am now (see below) just installing fresh to reduce "variables" in the debugging.
First I'd like to confirm it's not a asymmetric route issue. (I began debugging problems in November and some routing issues were seemingly corrected then, but problems quickly returned, and have remained intermittent.)
For example, right now (Fri Jan 20 16:06:13 CST 2017), I am trying a fresh manual install of SeaDAS and am seeing install_ocssw.py hang on different "parts" of the downloading. A rerun might get farther or not as far as just previously. Right now it seemed to be forging ahead, but then "timed out before SSL handshake". Subsequent runs now seem to hang earlier ("Installing common (2 of 13)").
We have been plagued by data downloads that work one minute and then fail on another attempt for another file. We've trying from various machine in subnets 130.39.188.x thru 130.39.191.x with similar behaviors.
So, to first eliminate the routing issue...
This machine is at xx.xxx.xx.xx, running a fully-updated CentOS 6.8, (I also rebuilt "git" to make sure it was linking with a "latest" OpenSSL. )
