24.237.158.14: /* Other Important Information */

Stub here to act as a table of contents sorts to our important computers / servers / related information.
===Loggernet Systems===
* Lognet (listed lower on the page) - [https://docs.google.com/a/alaska.edu/spreadsheets/d/1CFV-2dh7pPBvACJbi8AFLTF7aF6Bf3JSwRjbcY5aBMY/edit?usp=sharing LoggerNet configuration] (Partial GIPL & IARC) 
* Monitor real time connections here:
** http://ngeedata.iarc.uaf.edu/data/data.html
* Super Site Debian Laptop
** exclusively handles Super-site Data loggers at Poker Flat Research Range on an MD485 wired network

===Serial Server Systems===
What is a [[Serial Server]]? 
[[Several Important Network Devices]] (Covers much of the same ground) 
* [https://docs.google.com/a/alaska.edu/document/d/1rRO1Ess8hwZkxBgZB5HRP-FZ8u2NcKENp2TvAYmtYTE/edit?usp=sharing Fairbanks IARC Base Station server (Ralph) Configuration] 

* [https://docs.google.com/a/alaska.edu/document/d/1cvtqjE0w6MpFALUuruchsc71XF1WgvOJFbtLxnAWBQo/edit?usp=sharing Barrow Base Station server (Trout) Configuration] 

* [https://docs.google.com/a/alaska.edu/document/d/108gA9FC5sTJvvMaQ039XtKBFk9DH31bilRKUuF3_hq4/edit?usp=sharing Barrow BARC bandwidth tester (Grayling)Configuration ] 
* [https://docs.google.com/a/alaska.edu/document/d/1Fmh8lsWiJdNqu79rQfaMm7dj6GnruNk2WSrbzFa3pBg/edit?usp=sharing Lab 113 (Salmon) Configuration]
* [[Ser2Net Config Reference]] (Hopefully this reflects all of them)

* Barrow Raspberry Pi 1 ''Lost in the mail *Sad Emoji*'' 
* Barrow Raspberry Pi 2 ''Lost in the mail *Sad Emoji*'' 
* '''Barrow Dreamplug''' -- Kind of decommissioned at this point.
** It is old and still up in Barrow in the control shed. Still works but I sent the raspberry pis up to replace it. My plan is to replace it with a small server with a different computer architecture this winter. The reason for that over these small ARM processors is that I'm still trying to work around this weak telemetry problem. Thinking that if it is an x86 (well 64 bit but that style of CPU) that we can leave a copy of loggernet running up there so that when the network goes down as long as the unit is on we are still in business. I am working to put all of its configs in one location though. What was unique to it that hasn't been documented yet is that it used its second ethernet port as a DHCP server in support of a PTZ web cam. That required an additional package, special iptables rules, and some scripts in /usr/local/bin. On the to do list to get going at some point.

===Virtual Machines===
What is a [[Virtual Machine]]? 
====LogNet====
Primary LoggerNet server
* CentOS Linux virtual machine
* Located in IARC server room
* Function is ''main LoggerNet server'' for related projects.
* This computer pushes data to ngeedata after automated retrievals.

====NGEEDATA====
Primary Data processing server & data sharing web server 
* Debian Linux virtual machine
* Located in IARC server room
* Function is ''main data processing server'' and ''web server'' for sharing data with 3rd parties
* Online repositories for processing scripts:
** Cron related: https://github.alaska.edu/rcbusey/processing_bash_scripts
** Bash Utilities: https://github.alaska.edu/rcbusey/bash_utilities
** Python Utilities: https://github.alaska.edu/rcbusey/python_utilities
** DataPro V3 & other python utilities from Ross: https://github.com/rwspicer/csv_utilities

</pre>

A further modification would be to make the TimeIntoInterval commands use variables for the on & off times.
