LaunchMON is a software infrastructure that enables HPC run-time tools to co-locate tool daemons with a parallel job. Its API allows a tool to identify all the remote processes of a job and to scalably launch daemons into the relevant nodes.

Ansible aims to be a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible facilitates complex changes like zero-downtime rolling updates with load balancers. This package provides a curated set of community-maintained Ansible collections, which contain playbooks, roles, modules and plugins that extend Ansible.

Pam-mount is a PAM module to mount volumes when a user logs in. It can mount all local file systems supported by mount, as well as LUKS volumes encrypted with the user's log-in password.

libpcap is an interface for user-level packet capture. It provides a portable framework for low-level network monitoring. Applications include network statistics collection, security monitoring, network debugging, etc.

The Router Advertisement Daemon (radvd) is run on systems acting as IPv6 routers. It sends Router Advertisement messages specified by RFC 2461 periodically and when requested by a node sending a Router Solicitation message. These messages are required for IPv6 stateless autoconfiguration.

The Linux Thermal Daemon helps monitor and control temperature on systems running the Linux kernel.
