Using OpenBSD's chrooted httpd

Gespeichert von Marc Balmer am Sa., 12/22/2007 - 11:52

Copyright © 2003-2008 by Marc Balmer. All rights reserved. OpenBSD some time ago changed the mode of operation for the Apache webserver from the normal non-chrooted operation to chrooted operation. This enhances the security of the server on which Apache is run but it imposes a few challenges to the system administrator. In this article I will discuss selected aspects of running a chrooted HTTP daemon and present strategies on how to set up a chrooted environment for more complex applications like database access or using CGI-scripts.

The Java Framework for CGI

(This document describes version 1.01 of the framework) Copyright © 1996 by Marc Balmer, CH-4055 Basel, Switzerland. Internet applications written in the Java programming language are mostly designed as applets that run in a Java enabled browser like Netscape. There are, however, still many web-browser around that don't support Java. These need to use CGI (Common Gateway Interface) to access interactive pages on the web. Although CGI programs traditionally were realized using a scripting language like Perl or even the Bourne shell, nothing speaks against using Java to write CGI program.
