Official Internet Protocol Standards
By RFC Editor,

This page lists those RFCs that have not been obsoleted and which
therefore represent the current level of standardization of
standards-track specifications. It also lists the RFCs that have been
explicitly given the HISTORIC status (rather than simply obsoleted).

Dynamic Host Configuration Protocol - DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for
automating the configuration of computers that use TCP/IP. DHCP can be used to
automatically assign dynamic IP addresses to devices on a network,
to deliver TCP/IP stack configuration parameters such as the subnet mask and
default router, and to provide other configuration information such as the
addresses for printer, time and news servers.

Roaring Penguin PPPoE
RP-PPPoE is a free PPPoE client for Linux, NetBSD and Solaris,
by Roaring Penguin Software.
If your ISP uses PPPoE, but has given you a router, you may not need a PPPoE
client on your Linux box. DHCP may work fine. However, if you have a DSL
"modem" and your provider uses PPPoE, you need a PPPoE client like RP-PPPoE
to connect to your PPPoE service provider.

FTP: File Transfer Protocol
By Dr. D. J. Bernstein.
These pages are designed as a reference for the File Transfer Protocol (FTP).
Unlike the IETF FTP specifications, these pages describe how FTP actually
works (and doesn't work) in practice.
ftpparse:
ftpparse is a library written in C for parsing FTP LIST responses.
ftpparse is Open Source by D. J. Bernstein. Commercial use of ftpparse
is fine, as long as you inform him what programs you're using it in.

MRTG: The Multi Router Traffic Grapher
The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic
load on network-links. MRTG generates HTML pages containing graphical
images which provide a LIVE visual representation of this traffic.
MRTG is based on Perl and C and works under UNIX and Windows NT.
MRTG is freely available under the terms of the GNU General Public License.
-
RRD Tool
RRD is the acronym for Round Robin Database. RRD is a system to store
and display time-series data (i.e. network bandwidth, machine-room
temperature, server load average). It stores the data in a very compact
way that will not expand over time, and it presents useful graphs by
processing the data to enforce a certain data density.
It can be used either via simple wrapper scripts (from shell or Perl) or
via frontends that poll network devices and put a friendly user
interface on it.
If you know MRTG, you can think of RRDtool as a reimplementation of
MRTG's graphing and logging features. But RRDtool is not a replacement
for MRTG, as it does not implement the frontend and data aquisition
features of MRTG. RRDtool currently compiles on a number of different
Unix platforms as well as on NT.
RRDtool is open source available under the terms of the GNU GPL.
By Tobi Oetiker.
RRDtool Front-ends.

Cacti
Cacti is a complete frontend to RRDTool, it stores all of the necessary
information to create graphs and populate them with data in a MySQL
database. The frontend is completely PHP driven. Along with being able
to maintain Graphs, Data Sources, and Round Robin Archives in a
database, cacti handles the data gathering. There is also SNMP support
(using net-snmp) for those used to creating traffic graphs with MRTG.
Cacti is released under the GNU GPL, meaning that it is completely free.

Server Message Block - SMB
-
SAMBA.org - opening windows to a wider world
Samba is an open source software suite that implements the Server Message
Block (SMB) protocol for UNIX systems, providing seamless file and print
services to SMB clients, such as Windows 9x/Me/NT/2000 or LanManager.
SMB protocol is sometimes also referred to as the Common Internet File
System (CIFS), LanManager or NetBIOS protocol.
- Samba-TNG
Samba-TNG is a fork of Samba. It was derived from the same code but is being
developed independently.
The main philosophical difference is that the Samba project wants to
produce a Unix server capable of acting as an NT domain controller,
whereas the Samba-TNG project wants to basically be an NT domain
controller running on Unix, with a LDAP backend.
