doctl provides a unified command line interface to the DigitalOcean API.

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.

Btop++ provides unified monitoring of CPU, memory, network and processes.

This package provides a graphical console greeter for greetd. It doesn't need a Wayland compositor to be used.

Spindle is a tool for improving the performance of dynamic library and Python loading in HPC environments.

Iftop does for network usage what top does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts.

The Ansible roles provided by that can be used to manage Debian or Ubuntu hosts. In addition, a default set of Ansible playbooks can be used to apply the provided roles in a controlled way, using Ansible inventory groups.

The roles are written with a high customization in mind, which can be done using Ansible inventory. This way the role and playbook code can be shared between multiple environments, with different configuration in to each one.

Services can be managed on a single host, or spread between multiple hosts. DebOps provides support for different SQL and NoSQL databases, web servers, programming languages and specialized applications useful in a data center environment or in a cluster. The project can also be used to deploy virtualization environments using KVM/libvirt, Docker or LXC technologies to manage virtual machines and/or containers.

Tcptrack is a sniffer which displays information about TCP connections it sees on a network interface. This is a fork of Steve Benson’s tcptrack.

daemonize runs a command as a Unix daemon. It will close all open file descriptors, change working directory of the process to the root filesystem, reset its umask, run in the background, ignore I/O signals, handle SIGCHLD, etc. Most programs that are designed to be run as daemons do that work for themselves. However, you’ll occasionally run across one that does not. When you must run a daemon program that does not properly make itself into a true Unix daemon, you can use daemonize to force it to run as a true daemon.

wpa_supplicant is a WPA Supplicant with support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE 802.1X/WPA component that is used in the client stations. It implements key negotiation with a WPA Authenticator and it controls the roaming and IEEE 802.11 authentication/association of the WLAN driver.

This package provides the wpa_supplicant daemon and the wpa_cli command.

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

Neofetch is a command-line system information tool written in Bash. Neofetch displays information about your system next to an image, your OS logo, or any ASCII file of your choice. The main purpose of Neofetch is to be used in screenshots to show other users what operating system or distribution you are running, what theme or icon set you are using, etc.

This package provides a command line tool that can give numerous reports on memory usage on GNU/Linux systems.

HyFetch is a command-line system information tool fork of neofetch. HyFetch displays information about your system next to your OS logo in ASCII representation. The ASCII representation is then colored in the pattern of the pride flag of your choice. The main purpose of HyFetch is to be used in screenshots to show other users what operating system or distribution you are running, what theme or icon set you are using, etc.

Inetutils is a collection of common network programs, such as an ftp client and server, a telnet client and server, an rsh client and server, and hostname.

Facter is a tool that gathers basic facts about nodes (systems) such as hardware details, network settings, OS type and version, and more. These facts can be collected on the command line with the facter command or via the facter Ruby library.

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.

This package inherits pam-mount but is compiled specifically for use with the greetd log-in manager. It uses a different configuration location and PAM name space from the original.

This allows greetd-pam-mount to auto-(un)mount XDG_RUNTIME_DIR without interfering with any pam-mount configuration.

hungrycat prints the contents of a file to standard output, while simultaneously freeing the disk space it occupied. It is useful if you need to process a large file, don't have enough space to store both the input and output files, and don't need the input file afterwards. While similar in principle to running cat immediately followed by rm, hungrycat actually frees blocks as soon as they are printed instead of after the entire file has been read, which is often too late.

hostapd is a user-space daemon for WiFi access points and authentication servers. It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators, RADIUS client, EAP server, and RADIUS authentication server.

Nmap ("Network Mapper") is a network discovery and security auditing tool. It is also useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. It also provides an advanced netcat implementation (ncat), a utility for comparing scan results (ndiff), and a packet generation and response analysis tool (nping).

Dool is a command line tool to monitor many aspects of your system: CPU, Memory, Network, Load Average, etc. It also includes a robust plug-in architecture to allow monitoring other system metrics.

This package provides a command-line UEFI image editor, including cbfs, create-ffs, fmap, fspinfo, glzma, guid2english, microcode and utk CLI utilities.

Jnettop is a traffic visualiser, which captures traffic going through the host it is running from and displays streams sorted by bandwidth they use.

Autojump provides a faster way to navigate your file system, with a "cd command that learns". It works by maintaining a database of the directories you use the most from the command line and allows you to "jump" to frequently used directories by typing only a small pattern.
