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.

rex runs a supplied command or shell script on several hosts in succession or in parallel. It can also be used to copy a file or files to several hosts.

Dstat is a versatile replacement for vmstat, iostat, netstat, and ifstat. Dstat overcomes some of their limitations and adds some extra features, more counters and flexibility. Dstat is handy for monitoring systems during performance tuning tests, benchmarks or troubleshooting.

Dstat allows you to view all of your system resources in real-time, you can, e.g., compare disk utilization in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).

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.

Detox is a program that renames files to make them easier to work with under Unix and related operating systems. Spaces and various other unsafe characters (such as "$") get replaced with "_". ISO 8859-1 (Latin-1) characters can be replaced as well, as can UTF-8 characters.

Bfs is a variant of the UNIX find command that operates breadth-first rather than depth-first. It is otherwise compatible with many versions of find, including POSIX, GNU, and *BSD find.

Fail2Ban scans log files like /var/log/auth.log and bans IP addresses conducting too many failed login attempts. It does this by updating system firewall rules to reject new connections from those IP addresses, for a configurable amount of time. Fail2Ban comes out-of-the-box ready to read many standard log files, such as those for sshd and Apache, and is easily configured to read any log file of your choosing, for any error you wish.

Though Fail2Ban is able to reduce the rate of incorrect authentication attempts, it cannot eliminate the risk presented by weak authentication. Set up services to use only two factor, or public/private authentication mechanisms if you really want to protect services.

MASSCAN is an asynchronous TCP port scanner. It can detect open ports, and also complete the TCP connection and interact with the remote application, collecting the information received.

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.

UwUFetch is a system information tool in the lineage of NeoFetch, PFetch, HyFetch, and the like. It prints ASCII art of your system's logo as well as a summary of system information. UwUFetch's unique contribution is the uwu-ification of various words used in the description. For example, Guix becomes gUwUix.

This package provides a utility to flash a new firmware image to a Netgear device. It has been tested on Netgear EX2700, EX6120, EX6150v2, DNG3700v2, R6100, R6220, R7000, D7000, WNR3500, R6400, R6800, R8000, R8500, WNDR3800, but is likely to be compatible with many other Netgear devices.

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.

Lynis is a security auditing tool. It performs an in-depth security scan and runs on the system itself. The primary goal is to test security defenses and provide tips for further system hardening. It will also scan for general system information, vulnerable software packages, and possible configuration issues.

This is the user-space component to the Linux auditing system, which allows logging of system calls made by user-land processes. auditd is responsible for writing audit records to the disk. Viewing the logs is done with the ausearch or aureport utilities. Configuring the audit rules is done with the auditctl utility.

This package provides the /etc/services, /etc/protocols, and /etc/rpc files, which contain information about the IANA-assigned port, protocol, and ONC RPC numbers.

The GNU Shepherd is a daemon-managing daemon, meaning that it supervises the execution of system services, replacing similar functionality found in typical init systems. It provides dependency-handling through a convenient interface and is based on GNU Guile.

This package provides a tiny system info utility.

A program that looks for coreutils basic commands (cp, mv, dd, tar, gzip/gunzip, cat, etc.) currently running on your system and displays the percentage of copied data. It can also show estimated time and throughput, and provides a "top-like" mode (monitoring).

Fasd (pronounced similar to "fast") is a command-line productivity booster. Fasd offers quick access to files and directories for POSIX shells. It is inspired by tools like autojump, z, and v. Fasd keeps track of files and directories you have accessed so that you can quickly reference them in the command line.

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

GTK-based greeter for greetd, to be run under a compositor such as Cage.

SSHGuard protects hosts from brute-force attacks against SSH and other services. It aggregates system logs and blocks repeat offenders using one of several firewall backends.

nq can create very lightweight job queue systems which require no setup, maintenance, supervision, or any long-running processes.

pscircle visualizes Linux processes in the form of a radial tree.
