Introduction
H/OS 2 is the lastest operating system (flash image) for the Halon appliances. So far, it is pre-ínstalled on the Halon SPG 100/150/200/300/400/500 and Halon VSP (VMware and Xen) series appliances. H/OS 2 is booted by a firmware, which is also used for resetting the configuration and flashing (overwriting the Flash memory of) the appliances. Administration is carried out via a web application that connects to the appliance's operating system using a SOAP API, that administrators are free to use.
Getting started
An appliance that is either brand new, or that has been factory reset, is running on the default configuration. The getting started section describes the procedure of quick-starting the deployment of an appliance. If you know an appliance's password, but don't know it's IP address, the console comes handy. VSP users should read the virtualization document.
Web Administration
This chapter covers the mail gateway section of the Web Administration in particular. If something does not work as intended you may find this section about mail gateway troubleshooting interesting.
Common configurations
A few of the possible scenarios (or topologies) is way more common that the others. The getting started document describes the configuration of a single SPG/VSP being in front of a mail server, filtering mail messages (SMTP connections) for spam, viruses, outbreaks, DDoS attacks, and such. For increased security, outbound filtering, where users authenticate and submit messages through the SPG/VSP, can be configured.
Programming
Halon Scripting Language (also known as HSL) is used in H/OS 2 for programming different kinds of processes, like IP Policy (connection level) and Mail Content (document level) flows. The HSL section comes handy for advanced administrators with esoteric installations. Moving on, there is a SOAP API which be used when programming custom applications which is to interface with the appliances.
