Want to build a file server but bandwith protected

For bible sharing

[sunny7day]

I have audio bible in more than 450 different languages want to openly share to the world.

In the past I had setup a server but people use DDOS(?) and wasted alot of bandwith.

I need to have a solution to protect bandwith on my server.

solution to protect bandwith on my server

Were you expecting a one-line copy and paste that would solve your issues?

Nothing like that exists, with the exception of password protection.

Many sites are using CAPTCHA for downloads.

Have a look at the Apache modules:-

mod_bandwidth
mod_limitipconn

You can probably configure Apache to work in the way you need to. Most of these kinds of issues have usually been solved already.

DDOS

I suspect you don't really mean that? A Distributed Denial of Service attack is a complex thing to set up (usually requiring large botnets) and to be frank they wouldn't usually target a bible site (unless yours is particularly contentious).

If you're just dealing with a volume/bandwidth problem, then throttle it with the above two modules.

If you really are dealing with DDOS attacks then you'll probably need specialist advice, kit and configuration, or pass the problem to your hosting company to sort for you.

Many sites are using CAPTCHA for downloads.

I think that's also a really good idea, but I would look to reduce the problem first of all at the webserver level, then add CAPTCHA as a belt-and-braces measure.

I am not really sure if they were DDOS attack: many IPs download a same file, and their inbound port keep changing.

Since my files are more than 100MB each, so I have to make my site "download-manager friendly". Allowing multiple connection per file and resumable.

Not sure if CAPTCHA is the only solution but it would be nice if the user can just click then download. Maybe LinkLok URL work?

Illustrated? PDF? Text only will significantly reduce bandwidth. Just a different point of view. ALSO, some of what appears to be DDoS is actually SCRAPERS or OFFLINE RIPS of the site. Check UAs to see if there's anything there that is block worthy.
