I have a VPS with a mail server. Lately I have been thinking about using that VPS also for “sharing” files, i.e. for putting a file on my VPS and giving a link to that file on, for example, a forum that doesn’t allow attaching big files to your posts. (So as to void using services like rapidshare and similar).
So I don’t want to provide a file-sharing service myself, I just want anyone (without logging in) to be able to download the file the link to which I have given.
So my question is: what would be the simplest in configuration/least resource-hungry choice for this? Web-server? FTP-server with anonymous access? Which of web- or FTP-servers? Could you recommend something?
