DHCPD Configuration Editor (DCE) is a Web service that allows you to update MAC addresses in the dhcpd.conf of an ISC DHCP server. It can load a dhcpd.conf file from a server, save a modified dhcpd.conf file to a server, import a dhcpd.conf file from the local filesystem, export a modified dhcpd.conf to the local filesystem, and change the MAC address of previously declared host entries. It can be used with the minimalist General Configuration Form Manager server, or with Apache and its PHP module.
Epikscan is a cluster aware, diagnostic script that runs basic health checks and gathers detailed, addressable system information from an RHEL, Scientific Linux, Oracle/OVM2, or CentOS 4, 5, or 6 system. A single archive is created for each host, containing the scan data along with linking information that can be merged with scans from other nodes to produce a cluster oriented report. HTML, text, XML, and SQLite3 database reports can be optionally generated to support both manual and automated fault analysis. The scan and merge process attempts to heuristically identify possible problems with the node or cluster configuration and highlights them in red to speed up the review and resolution process.
cronbot is a wrapper script for cron jobs. Rather than running your job/script directly, you run it through cronbot, and it will allow a little more control to help keep things from getting out of hand. The default behavior is to only allow one instance of your job to run. This can be changed with the --duplicate option. You can also pass in a maximum time of execution for a job or add a random amount time to delay the start of your job. By default, jobs are run with a default "nice" value, which is usually 10.
Ansible is a radically simple deployment, configuration, and command execution framework. It is dead simple and painless to extend. Extending Ansible does not require programming in any particular language; you can write modules as scripts or programs which return simple JSON. It’s also trivially easy to just execute useful shell commands.
