NFS over CIPE-VPN tunnels

Post date: May 23, 2005, 16:05 Category: Network Views: 3386 Comments
Tutorial quote: The Network File System (NFS) is a standard protocol for sharing file services with Linux and Unix computers. It is a distributed file system that enables local access to remote disks and file systems and is based on the client\server architecture. Although easy to configure, it is typically used only to transfer data over an intranet or LAN because of its transparency and security potholes when exposed to the risks of the Internet. However, it still can be employed -- without compromising security -- to share files over the Internet by configuring it to run on a Virtual Private Network (VPN) connection. This article will show you how to set up NFS to run over a CIPE-VPN connection between two Linux systems.

Install OpenWRT, Chillispot, FreeRadius Based Managed Hotspot(s) Including PayPal Payment Gateway

Post date: March 23, 2008, 14:03 Category: Miscellaneous Views: 6673 Comments
Tutorial quote: If you have ever tried to implement one of the hotspot HowTos on this and other sites, it might have dawned on you that this is not an easy feat to accomplish. Amazingly most solutions also leave out the most important part – how to get paid by the punters using the hotspot. Some will offer prepaid solution or access tickets that need to be printed, but this will require staff being involved on the premises. And in particular, once you want to offer a professional service and not just a toy concept it gets tricky – and expensive. Just imagine all the servers you need to provide redundant and load balanced freeradius, mysql and web servers. It is generally not worth the effort and expense for just one hotspot – unless of course you are willing to accept outages, unhappy customers etc.

How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)

Post date: October 27, 2009, 23:10 Category: Network Views: 6068 Comments
Tutorial quote: This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

CGI Programming on the World Wide Web

Post date: December 12, 2005, 17:12 Category: Programming Views: 3595 Comments
Tutorial quote: The Common Gateway Interface (CGI) emerged as the first way to present dynamically generated information on the World Wide Web. CGI allows the computer to generate Web pages instantly at the user's request rather than being written by someone in advance. And at the time of this writing, it remains the only stable and well-understood method for creating such pages. Java presents problems that have not yet been solved. Other products are currently just in the announcement stage.

CGI is fun. You can get a kick out of writing scripts that perform tricks for you, and the users enjoy the spice the scripts add to your Web pages. But CGI has a serious side too: It lets the Internet offer the kind of interactive, user-driven applications that modern computer users have come to expect. CGI opens up an entire class of modern applications to the Web.
