Sipcalc is an advanced command-line IP subnet calculator. It can take multiple forms of input (IPv4/IPv6/interface/hostname) and output a multitude of information about a given subnet.

Features include:

• IPv4

  • Retrieving of address information from interfaces.

  • Classfull and CIDR output.

  • Multiple address and netmask input and output formats (dotted quad, hex, number of bits).

  • Output of broadcast address, network class, Cisco wildcard, hosts/range, network range.

  • The ability to split a network based on a smaller netmask, now also with recursive runs on the generated subnets. (also IPv6)

• IPv6

  • Compressed and expanded input and output addresses.

  • Standard IPv6 network output.

  • v4 in v6 output.

  • Reverse DNS address generation.

This package provides a simple, configurable system information tool.

Resource monitor that shows usage and stats for processor, memory, disks, network and processes.

stress-ng stress-tests a computer system by exercising both physical subsystems as operating system kernel interfaces. It can stress the CPU, cache, disk, memory, socket and pipe I/O, scheduling, and much more, in various selectable ways. This can trip hardware issues such as thermal overruns as well as operating system bugs that occur only when a system is being thrashed hard.

You can also measure test throughput rates, which can be useful to observe performance changes across different operating system releases or types of hardware. However, stress-ng is not a benchmark. Use it with caution: some of the tests can make poorly designed hardware run dangerously hot or make the whole system lock up.

Compared to its inspiration, stress, stress-ng offers many additional options such as the number of bogo operations to run, execution metrics, verification of memory and computational operations, and considerably more stress mechanisms.

The Stress Terminal UI displays graphs of the CPU frequency, utilization, temperature and power.

GNU Rot[t]log is a program for managing log files. It is used to automatically rotate out log files when they have reached a given size or according to a given schedule. It can also be used to automatically compress and archive such logs. Rot[t]log will mail reports of its activity to the system administrator.

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

This package provides an on demand system DBus service. It allows callers to configure network authentication and domain membership in a standard way. Realmd discovers information about the domain or realm automatically and does not require complicated configuration in order to join a domain or realm. Dbus system service that manages discovery and enrollment in realms/domains like Active Directory or IPA.

Tcpdump is a command-line tool to analyze network traffic passing through the network interface controller.

IGT GPU Tools is a collection of tools for development and testing of the Intel DRM driver. There are many macro-level test suites that get used against the driver, including xtest, rendercheck, piglit, and oglconform, but failures from those can be difficult to track down to kernel changes, and many require complicated build procedures or specific testing environments to get useful results. Therefore, IGT GPU Tools includes low-level tools and tests specifically for development and testing of the Intel DRM Driver.

cbatticon is a lightweight battery icon that displays the status of your battery in the system tray.

The ACPICA project provides an OS-independent reference implementation of the ACPI specification. ACPICA code contains those portions of ACPI meant to be directly integrated into the host OS as a kernel-resident subsystem, and a small set of tools to assist in developing and debugging ACPI tables.

This package contains only the user-space tools needed for ACPI table development, not the kernel implementation of ACPI.

Bash screenshot information tool which can be used to generate those nifty terminal theme information and ASCII distribution logos in everyone's screenshots nowadays.

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.

This package contains tools for Allwinner devices:

1. sunxi-fexc, bin2fex, fex2bin: Compile a textual description of a board (.fex) to a binary representation (.bin).

2. sunxi-fel: Puts an Allwinner device into FEL mode which makes it register as a special USB device (rather than USB host). You can then connect it to another computer and flash it from there.

3. sunxi-nand-part: Partitions NAND flash.

4. sunxi-bootinfo: Reads out boot0 and boot1 (Allwinner bootloader) parameters.

5. sunxi-pio: Sets GPIO parameters and oscillates a GPIO in order to be able to find it.

6. sunxi-meminfo: Prints memory bus settings.

7. sunxi-nand-image-builder: Prepares raw NAND images.

UDPcast is a file transfer tool that can send data simultaneously to many destinations on a LAN. This can for instance be used to install entire classrooms of PC's at once. The advantage of UDPcast over using other methods (nfs, ftp, whatever) is that UDPcast uses UDP's multicast abilities: it won't take longer to install 15 machines than it would to install just 2.

The Neighbor Discovery Protocol Proxy Daemon (ndppd) proxies some IPv6 NDP messages between interfaces to allow IPv6 routing between machines that are in the same network but not on the same local link. It currently only supports Neighbor Solicitation and Neighbor Advertisement messages.

pam-hooks is a tiny PAM module enabling the execution of hook scripts when a PAM session is opened or closed. The typical use case is the need of doing some per-user set-up when a user logs via a PAM-aware login mechanism and/or the need of doing some per-user clean-up when the user logs out.

GNU adns is a C library that provides easy-to-use DNS resolution functionality. The library is asynchronous, allowing several concurrent calls. The package also includes several command-line utilities for use in scripts.

C-ares is a C library that performs DNS requests and name resolution asynchronously. It is intended for applications which need to perform DNS queries without blocking, or need to perform multiple DNS queries in parallel. The primary examples of such applications are servers which communicate with multiple clients and programs with graphical user interfaces.
