In their own words
LCFG
LCFG is a free, GPL-licensed system for automatically installing and managing configurations across large groups of Unix machines. It targets sites where systems differ and change frequently. Administrators keep source settings on a central server; LCFG compiles them into XML profiles that clients download when changes occur. Client components react to resource changes by generating configuration files and reconfiguring related daemons. A package component aligns installed software with each machine’s profile. New machines can be installed over a network file system after source files are created, using a boot floppy or PXE. LCFG is self-hosted and agent-based, with patch management and HTTP resource transport. Listed supported platforms include Ubuntu 20.04, 22.04, and 24.04; FAQ material also names Fedora Core 3, 5, and 6 and Scientific Linux 5. Solaris support is weaker and un-packaged, Mac OS X is experimental, and the demonstration Windows client lacks real components. Documentation covers configuration, dynamic networking, and build tools.
Rex
Rex is a free, open-source automation framework for managing local computers and remote machines over SSH. It runs self-hosted and agentless on Linux and Windows, with support also listed for RHEL/CentOS, Fedora, OpenWRT, BSDs, and Solaris. Projects keep inventory, environments, authentication details, and tasks in a Rexfile. You can combine local or remote execution, push or pull management, and imperative or declarative styles. Tasks can install packages, upload configuration files, start services, and trigger actions when files change. Rex uses a DSL compatible with Perl syntax and can be extended with Perl modules or custom code. Authentication documentation covers passwords, SSH keys, passphrases, external credential sources, and ssh-agent. The control host needs Perl and dependencies; managed hosts need Perl 5 and a valid SSH account. Installation is recommended through CPAN, with package-manager and source options. Apache 2.0 licensing applies to Rex and its parts.
