Introduction

libaddr is an easy to use C++ library that parses IP & Unix addresses to C++ objects. This includes parsing one or more IPv4 and IPv6 addresses, with a port or a CIDR mask and the latest also supports real or abstract paths to Unix addresses.

The library also includes functions to list interfaces (i.e. "eth0", "eth1", etc.) and your route tables (see route(8).) The library actually includes a tool, ipv4_routes, one can use to list routes as the libaddr sees them.

The existing parser has limits since it is streaming the input characters instead of converting the input to tokens that can be managed. However, it is still much more powerful than what the default C library functions offer.

csspp

CSS Preprocessor (csspp) is a scripting language that transforms advanced (extended) CSS code into a script that browsers can read.

The input to csspp can be the same as standard CSS, or it can use extensions as described below such as using basic math, embedding rules in other rules (cascading by nesting) and many other things.

The project offers a C++ library that can readily be used in your own C++ project and a command line tool.

The Communicator Daemon is a service used to communicate between any number of nodes in any number of clusters, local (same LAN) and remote. The network connection can be plain text (LAN, fast) or encrypted (remote, safe).

The Communicator service supports a text message which has its own compact format. You may also use JSON if it makes it easier with your systems (such as a browser).

The daemon supports a basic set of system messages such as QUIT and CONNECT. It comes with a library that other services are expected to use to connect and manage their connection with the Communicator ...

The IP Manager is a tool we created in order to manage our DNS zone files.

Working on those manually is time consuming and many of the parameters (most, actually!) are repeated between all the different files. Not only that, you are much more likely to have (many) mistakes.

Instead, the ipmgr command line tool reads configuration files and transforms them in Bind9 compatible zone files. It also takes care of restarting bind9 when something changed.

Ultimately, we would like to use the rndc and nsupdate tools to dynamically create zones and add sub-domains to them. However, our attempts at using those tools at the time we created ipmgr did not succeed. Setting up the permissions properly seems to require quite a bit of work. Note that although we do not use those tools, the ipmgr configuration files can be setup for dynamically updateable zones. This is important in various situations such as automatically setting up an SSL (TLS really now) certificate with letsencrypt.

Sitter

The sitter project is a daemon, plugins, and tools that can be used to watch a computer to make sure that it runs smoothly.

It has the ability to verify that a process is running. A service responds to a ping. That the memory is not maxed out. Ensure the disk drive is not close to being full. Etc.

The Snap! Logger Project

Originally, this project was a break up of the log.cpp and log.h from the libsnapwebsites to its own project. However, that implementation had a dependency on log4cplus which has all sorts of drawbacks for our Snap! environment. Don't get me wrong, up to here, it served us well and log4cplus version 1.2.x works very well.

That being said, our way of handling configuration files, the fact that we like to use fork() and a few other things, made us think that having our own implementation of a logger would improve our general environment quite a bit. This newer version of the logger is the result.

Introduction

Snap! comes with many different projects, all of which need a common set of cmake rules and some of those are rather complex. For that reason we created a common project used to compile all of those projects. This project is the Snap! CMake Modules.

Introduction

WARNING: We are in the process of replacing this tool with snapmanager.cgi and snapmanagerdaemon which together allow an administrator to manage his cluster of computers. We already installed a 12 computer cluster with these two tools. At this time, the snapmanager is still necessary to setup the domains and websites tables, but that too will be converted to an interface accessible through snapmanager.cgi.

The Snap! Manager graphical tool was created in order to setup the basics in the database. This is important because without those basics snapcgi and snapserver do not know ...

Introduction

The libtld is a C/C++ library used to extract the TLD from a URI. This allows you to extract the exact domain name, sub-domains, and all the TLDs (top level, second level, third level, etc.)

The problem with TLDs is that you cannot know where the domain starts. Some domains can use one top-level domain, others use two, three, etc. (up to five at this time). However, it may be useful to know where the domain is to have the exact list of sub-domains. For example, if you want to force www. at the start of the domain name if no other sub-domains are specified, then you need to ...
