SYSTEM GRAB BAG


WELCOME!

This site contains utilities and tools for system administrators and programmers
across multiple operating systems. The hope is that this is useful for system
administrators regardless of operating system. While the content at the moment
is primarily focused around Unix and Unix-like operating systems such as Linux,
FreeBSD, OpenBSD, and others, the hope that it helpful for everyone.

This site is also intended to be resource friendly and to be light so that it
can run well whether you have a low-end computer from 10 years ago or a high end
computer right off the factory floor. This site is also intended to be mobile
friendly so that devices with smaller screens (such as phones or tablets) can
also use these tools and read the reference material that is available here
incredibly easily, without sacrificing the utility of these tools on desktop
computers.


TOOLS AND UTILITIES


GENERAL

 * Computer Size Converter - convert easily between bytes, kilobytes, megabytes,
   terabytes, petabytes, etc. This tool also provides the number of 8-bit
   (octets), 16-bit (hextets), 32-bit, 64-bit, and 128-bit groupings which may
   be useful in situations where needing to know this is needed.
 * Timestamp Converter and Parser - convert easily between different types of
   timestamps in use by various different computer systems today. It accepts
   natural input like 1999-01-01 00:03:33 so you can easily convert between
   timestamps without having to have any (for example if you only have log files
   that have human readable dates and times).
 * Base 2, 8, 10, 16, and 36 Converter - quickly convert between numbers of
   various bases and learn about the different numbering systems used in
   computing. Multiple different bases are shown on one page with quick links to
   some common numbers.
 * IPv4 Subnet Calculator - enter in an IP address or an IP network in CIDR
   notation and find out the range of IPs that are in the range, the reverse
   DNSes of the beginnings and ends, and which RIR or organization operates a
   network quickly and easily all from your browser. Lots of different stats,
   along with popular IP networks, are also given as suggestions.


UNIX


GENERAL

 * Unix Permissions Calculator - or "chmod" calculator, this tool is provided to
   help provide both information on what access permissions are available on
   Unix based systems as well as being able to convert between different forms.
 * rsync Command Generator - this tool helps to assist you to generate commands
   for the powerful rsync utility in an easy to use, yet powerful, user
   interface.


LINUX

 * systemd Unit Security - this tool helps to analyze systemd service files and
   configurations to help provide more secure services. It also can be used for
   generating parts of the unit file directly. It has a simple to use interface,
   focusing on making it incredibly easy to create secure configurations without
   sacrificing needed functionality.


REFERENCE

 * Man (Manual) Pages - generally used on Unix-type operating systems, a copy of
   man pages are available.
 * TLDR Pages - quick and useful reference for the most common usages of
   particular commands.
 * Tool Pages - A lot of the tools, such as the Unix Permissions Converter or
   the Timestamp Converter and Parser also have information on their respective
   pages.
