The 'netsnmp' module provides a full featured, tri-lingual SNMP (SNMPv3, SNMPv2c, SNMPv1) client API. The 'netsnmp' module internals rely on the Net-SNMP toolkit library.
The net-snmp-utils package contains various utilities for use with the NET-SNMP network management project. Install this package if you need utilities for managing your network using the SNMP protocol. You will also need to install the net-snmp package.
The net-tools package contains basic networking tools, including ifconfig, netstat, route, and others. Most of them are obsolete. For replacement check iproute package.
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.
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.
