When I attach my BBB to my computer, I can view 'flash drive' WEB pages from the mounted BBB. For this to happen, no WEB Server is required as my computers browser is just reading the various web files needed to view the content as a "web page". However, if I browse onto the BBB from my network via the ip my router's DHCP has assigned to it, (or from the USB RNDS wired connection), the BBB spits out WEB pages. What server is running on the BBB to do this. I have looked at the processes running on the BBB with TOP and systemctl. I see nothing that indicates what's going on. I was expecting Apache or Lighttpd or something similar.
What I'm really trying to do is find out where I can put my own custom Web pages on the BBB so that it can serve up my own content. I've found Blog postings where people have installed a Web server on the BBB, but I don't think this is really required as it already seems to be doing a good job with its own content. Any pointers or links would be greatly appreciated.
