I am trying to create a so called origin server for storing the hls chunks and the manifest file on a remote server. The sending machine running ffmpeg is with IP: 192.168.178.50 and the web server which has to store both the HLS chunks and the manifest file is with IP: 192.168.178.100. My ffmpeg transcoding command line is:
$ ffmpeg -i 01_llama_drama_1080p.mp4 -profile:v high -level 5.2 -s 1920x1080 -strict -2 -start_number 0 -hls_time 6 -hls_list_size 0 -f hls http://192.168.178.100/hls/test.m3u8

[hls @ 0x24997e0] Cannot use rename on non file protocol, this may lead to races and temporarly partial files
But no matter what method I am using I got in the access log of my apache web server the following errors:
$ tail -f /var/log/apache2/access.log 192.168.178.50 - - [27/Jun/2017:10:40:45 +0000] "POST /hls/test.m3u8 HTTP/1.1" 404 469 "-" "Lavf/56.40.101" 192.168.178.50 - - [27/Jun/2017:10:40:45 +0000] "POST /hls/test12.ts HTTP/1.1" 404 469 "-" "Lavf/56.40.101" 192.168.178.50 - - [27/Jun/2017:10:40:46 +0000] "POST /hls/test.m3u8 HTTP/1.1" 404 469 "-" "Lavf/56.40.101" 192.168.178.50 - - [27/Jun/2017:10:40:46 +0000] "POST /hls/test13.ts HTTP/1.1" 404 469 "-" "Lavf/56.40.101" 192.168.178.50 - - [27/Jun/2017:10:40:47 +0000] "POST /hls/test.m3u8 HTTP/1.1" 404 469 "-" "Lavf/56.40.101" 192.168.178.50 - - [27/Jun/2017:10:46:44 +0000] "POST /hls/test0.ts HTTP/1.1" 404 468 "-" "Lavf/56.40.101" 192.168.178.50 - - [27/Jun/2017:10:46:51 +0000] "POST /hls/test.m3u8 HTTP/1.1" 404 469 "-" "Lavf/56.40.101"
These are the supported methods on my web server:
$ nmap -Pn -p 80 --script http-methods 192.168.178.100 Starting Nmap 7.01 ( https://nmap.org ) at 2017-06-27 10:47 UTC Nmap scan report for 192.168.178.100 Host is up (0.0015s latency). PORT STATE SERVICE 80/tcp open http | http-methods: |_ Supported Methods: GET HEAD POST OPTIONS Nmap done: 1 IP address (1 host up) scanned in 0.34 seconds
My web server is running apache2 on Ubuntu 16.04:
$ apache2 -v Server version: Apache/2.4.18 (Ubuntu) Server built: 2017-06-26T11:58:04
So according to the access.log file no matter what method I define in the ffmpeg command line it is always trying to upload the chunks using HTTP POST, but the latter is already supported and the directory I am directing the chunks has even 777 rights. Am I missing something here?

Answer
I have created a bash script, which is installing NGINX, configuring it and limiting the access to a certain IP network on my Github page. You can check the solution at: Origin Server running on NGINX. The point is that as @mata said HTTP POST requires some kind of a handle which to process the POST requests and save them to the storage or you can use HTTP PUT, but in this case you need to explicitly allow it, because it is by default not allowed. My solution is actually allowing HTTP PUT only in one specific directory and it is also limiting the HTTP PUT method to only one IP. Make also sure to check my WIKI page for more detailed explanation.
