NetBox is an IP address management (IPAM) and data center infrastructure management (DCIM) tool. Initially conceived by the network engineering team at DigitalOcean, NetBox was developed specifically to address the needs of network and infrastructure engineers. It is intended to function as a domain-specific source of truth for network operations.
NetCDF (network Common Data Form) is an interface for array-oriented data access and a freely-distributed collection of software libraries for C, Fortran, C++, and perl that provides an implementation of the interface. The NetCDF library also defines a machine-independent format for representing scientific data. Together, the interface, library, and format support the creation, access, and sharing of scientific data. The NetCDF software was developed at the Unidata Program Center in Boulder, Colorado. NetCDF data is: o Self-Describing: A NetCDF file includes information about the data it contains. o Network-transparent: A NetCDF file is represented in a form that can be accessed by computers with different ways of storing integers, characters, and floating-point numbers. o Direct-access: A small subset of a large dataset may be accessed efficiently, without first reading through all the preceding data. o Appendable: Data can be appended to a NetCDF dataset along one dimension without copying the dataset or redefining its structure. The structure of a NetCDF dataset can be changed, though this sometimes causes the dataset to be copied. o Sharable: One writer and multiple readers may simultaneously access the same NetCDF file.
This packages provides a 'netconsole' service for loading of netconsole kernel module with the configured parameters. The netconsole kernel module itself then allows logging of kernel messages over the network.
Netdiscover is an active/passive address reconnaissance tool, mainly developed for those wireless networks without dhcp server, when you are wardriving. It can be also used on hub/switched networks. Built on top of libnet and libpcap, it can passively detect online hosts, or search for them, by actively sending arp requests, it can also be used to inspect your network arp traffic, and find network addresses using auto scan mode, which will scan for common local networks.
NetHogs is a small "net top" tool. Instead of breaking the traffic down per protocol or per subnet, like most such tools do, it groups bandwidth by process and does not rely on a special kernel module to be loaded. So if there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this, and if it's some kind of spinning process, kill it.
The netpbm package contains a library of functions which support programs for handling various graphics file formats, including .pbm (portable bitmaps), .pgm (portable graymaps), .pnm (portable anymaps), .ppm (portable pixmaps) and others.
The netpbm-progs package contains a group of scripts for manipulating the graphics files in formats which are supported by the netpbm libraries. For example, netpbm-progs includes the rasttopnm script, which will convert a Sun rasterfile into a portable anymap. Netpbm-progs contains many other scripts for converting from one graphics file format to another. If you need to use these conversion scripts, you should install netpbm-progs. You'll also need to install the netpbm package.
NetSED is small and handful utility designed to alter the contents of packets forwarded through your network in real time. It is really useful for network hackers in following applications: * black-box protocol auditing - whenever there are two or more proprietary boxes communicating over undocumented protocol (by enforcing changes in ongoing transmissions, you will be able to test if tested application is secure), * fuzz-alike experiments, integrity tests - whenever you want to test stability of the application and see how it ensures data integrity, * other common applications - fooling other people, content filtering, etc - choose whatever you want to.
netsniff-ng is a high performance Linux network sniffer for packet inspection. It can be used for protocol analysis, reverse engineering or network debugging. The gain of performance is reached by 'zero-copy' mechanisms, so that the kernel does not need to copy packets from kernelspace to userspace. netsniff-ng toolkit currently consists of the following utilities: * netsniff-ng: the zero-copy sniffer, pcap capturer and replayer itself. * trafgen: a high performance zero-copy network packet generator. * ifpps: a top-like kernel networking and system statistics tool. * curvetun: a lightweight curve25519-based multiuser IP tunnel. * ashunt: an autonomous system trace route and ISP testing utility. * flowtop: a top-like netfilter connection tracking tool. * bpfc: a tiny Berkeley Packet Filter compiler supporting Linux extensions.
Nettle is a cryptographic library that is designed to fit easily in more or less any context: In crypto toolkits for object-oriented languages (C++, Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel space.
