Maximum PC

What is the maximum length that a file name can be on a Linux system (32-bit) running Apache HTTP server? (Server version is 2.2.17)

Additionally, can you do things like this:

Filename: connection.guest.php
or-
Filename: connection.guest.inc

Or do you have to stick to a filename, a period, and then an extension only?

Someone told me it was 24 cahracters (not including the extension), but I'm not sure if that's even true, espeically on a linux system. What is the recommended max that I should use for a web server on Linux running Apache?

I don't know about the max length, but pretty sure you can do whatever the fuck you want.

I'm sure pretty much anything will fly with Linux. I'm more or less concerned with potential issues with client computers viewing websites... I know obviously to try to use dashes not underscores, and no spaces in filenames, and that Linux file systems are case-sensitive (as in, use lower case), etc, etc.

Could a filename that excessively long or have an excessive number of periods in the filename affect a client computer's web browser or is that not even an issue?
