Tools and patches for the Linux Diskquota system as part of the Linux kernel

Super GRUB2 Disk helps you to boot into most any Operating System (OS) even if you cannot boot into it by normal means.

GaryOS is an entire GNU/Linux system in a single bootable file. It is also a Builder system to create and package Gentoo installations. Builder creates custom root filesystems that GaryOS can load into memory in place of its own. GaryOS can build new or updated versions of itself from within itself. Primary uses: * System rescue and recovery * Anonymous and secure workstation * GNU/Linux learning environment * Installation of Gentoo Unique advantages: * Source-based distributions are more flexible and powerful than binary ones * A single Kernel file is easier to manage and boot than an ISO image * GaryOS is stored on media as a resident of it, not the purpose of it No other GNU/Linux distribution takes the same approach or has the same features as GaryOS.

Arch Linux is an independently developed, i686/x86-64 general purpose GNU/Linux distribution versatile enough to suit any role. Development focuses on simplicity, minimalism, and code elegance. Arch is installed as a minimal base system, configured by the user upon which their own ideal environment is assembled by installing only what is required or desired for their unique purposes. GUI configuration utilities are not officially provided, and most system configuration is performed from the shell and a text editor. Based on a rolling-release model, Arch strives to stay bleeding edge, and typically offers the latest stable versions of most software.

openQRM is a web-based open source datacenter management and hybrid cloud computing platform that integrates flexibly with existing components in enterprise data centers. Releases available at https://github.com/openQRM/openqrm-community. Please visit http://www.openqrm-enterprise.com for latest 5.3 free Community Release. Includes important security updates, bugfixes and enhancements especially for KVM and Cloud plugin. openQRM abstracts Virtualization and supports the following virtualization technologies: KVM, XEN, Citrix XenServer, VMWare ESX & LXC. The Hybrid Cloud Connector in openQRM supports a range of private or public cloud providers to extend your infrastructure on demand via Amazon AWS, Eucalyptus or OpenStack. openQRM automates provisioning, virtualization, storage and configuration management, and it takes care of high-availability.

cpulimit is a per-process cpu usage limiter (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you don't want them to eat too much cpu. It is able to adapt itself to the overall system load, dynamically and quickly.

UEFI GPT fdisk is a port to UEFI of the famous GPT fdisk partitioning tool, see http://sourceforge.net/projects/gptfdisk/ . Now since this program runs directly under UEFI shell you don't need to *boot* the system to convert/edit partition tables.

RapidDisk is a Linux kernel module to dynamically create, remove, and manage RAM disk volumes. Ramdisks are a method by you which can allocate parts of your RAM for high performing file data storage.

Recursive LDD (recursive-ldd) is a Perl script that allows displaying a tree-like hierarchy of shared library dependencies. The script calls on the standard Linux ldd utility in a recursion for every listed binary and library. It completes running when no matches are found in the current branch. It can also print unique values only as well as environment variables that affect the loading of libraries: LD_LIBRARY_PATH and LD_PRELOAD. Same limitations to standard ldd apply. Recursive-ldd cannot check libraries without read permissions.

The scsirastools package adds several Linux SCSI tools that can be used to service and maintain disk storage devices. It handles SCSI, Linux SW RAID, SAS, SATA, and USB devices via SCSI emulation. For details & rpms, see http://scsirastools.sf.net.

l7-filter classifies packets based on patterns in application layer data. This allows correct classification of P2P traffic that uses unpredictable ports as well as standard protocols running on non-standard ports.

bootE Linux is yet another minimalist Linux distribution and is contained entirely on a single floppy disk. It supports only single user mode, and is intended as a repair/rescue/emergency distribution.

Freedom OS aims to be stable and free operating system, and include features like: latest stable linux kernel, GNU userland, tcsh as default shell, pkgsrc for easy packages management

Obsolete tools for resizing ext2 filesystems. Not maintained since 2004. The majority of this functionality was included into e2fsprogs years ago.

LiveCD is a "Complete FreeBSD System running on CD".

A JBD is a bootable CD that, in turn, boots a Slackware Linux system that is on a device connected to a personal computer. A JBD also serves as a handy Live CD for rescue, repair or whatever purpose you find for it.

Salvare is a Linux distribution specifically aimed at small credit-card sized CDs which typically hold around 34MB of data. It is aimed at providing a useful workstation, as well as rescue environment in a small package.

A Linux snoop driver and userspace utilities providing file descriptor/tty monitoring capabilities.

'finddouble' application searches into a directory and all its sub directories. If it finds several times the same file, a warning message is displayed, but no other action is taken. It's main use is to help you optimize you disk usage.

free apptoservice

Perl-based syslog watcher that matches certain login failures (SSH, FTP, POP3) and can dynamically block and email an alert, helping to monitor and manage hosting servers. NOTE: Although no recent updates, I'm still able/willing to update this code.

Cerber -- system firewall mechanism. It's a kernel module, which is a complete security solution for FreeBSD.

It is a Uruguayan Linux distribution. Can be used from floppy disks, cdroom or you can install it in your hard disk. It has been designed to be fast and effective without leaving of side the graphical aspect for the user.

ClamFS is a FUSE-based user-space file system for Linux with on-access anti-virus file scanning through clamd daemon. ClamFS has moved to Github. Please navigate to github.com/burghardt/clamfs.

A framework for allocation of system resources (such as CPU, mem, I/O and network) based on user defined classification of work within the system.
