The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic
load on network-links. MRTG generates HTML pages containing PNG images which
provide a LIVE visual representation of this traffic. Check
for an example. MRTG is based on Perl and C and works under UNIX and Windows
NT.
MRTG is being successfully used on many sites around the net.

Cactid is a poller for Cacti that primarily strives to be as fast as
possible. For this reason it is written in native C, makes use of POSIX
threads, and is linked directly against the net-snmp library for
minmumal SNMP polling overhead. Cactid is a replacement for the default
cmd.php poller so you must decide if using Cactid makes sense for your
installation.
nrpe is used to execute Nagios plugins on remote hosts and report the results
to the main Nagios server. From the Nagios homepage:
Allows you to execute "local" plugins (like check_disk, check_procs, etc.) on
remote hosts. The check_nrpe plugin is called from Nagios and actually makes
the plugin requests to the remote host. Requires that nrpe be running on the
remote host (either as a standalone daemon or as a service under inetd).
The Net::SNMP module implements an object oriented interface to the
Simple Network Management Protocol. Perl applications can use the
module to retrieve or update information on a remote host using the
SNMP protocol. The module supports SNMP version-1, SNMP version-2c
(Community-Based SNMPv2), and SNMP version-3. The Net::SNMP module
assumes that the user has a basic understanding of the Simple Network
Management Protocol and related network management concepts.
rtGui is a web based front end for rTorrent - a command line
BitTorrent client. It's written in PHP and uses XML-RPC to communicate
with the rTorrent client.
Features
* List all torrent downloads or by
* started/stopped/complete/incomplete/seeding status.
* Sort view by any of the displayed columns.
* View detailed torrent information.
* Stop/start/hash-check torrent.
* Set upload/download speed cap.
* Add torrents by URL.
* Does not require mySQL or any other database.
* Set priority per torrent or file.
Namecoin is an open source decentralized key/value registration and transfer
system based on Bitcoin technology (a decentralized cryptocurrency).
It allows you to:
* Securely register and transfer arbitrary names (keys), no possible
censorship!
* Attach values (data) to the names (currently up to 520 bytes, will be
extended)
* Trade and transact namecoins, the digital currency NMC
To register a name, you must own some namecoins (NMC, the internal
cryptocurrency used by the software).
High performance RTMP/RTSP streaming server
rtmpd is a high performance streaming server able to stream
(live or recorded) in the following technologies:
- To and from Flash (RTMP,RTMPE, RTMPS, RTMPT, RTMPTE)
- To and from embedded devices: iPhone, Android
- From surveillance cameras
- IP-TV using MPEG-TS and RTSP/RTCP/RTP protocols
Also, rtmpd can be used as a high performance rendez-vous server.
For example, it enables you to do:
- Audio/Video conferencing
- Online gaming
- Online collaboration
- Simple/complex chat applications
"echoping" is a small program to test (approximatively) performances of a
remote host by sending it TCP "echo" (or other protocol) packets.
- uses the protocols echo, discard, chargen or HTTP,
- uses UDP instead of TCP for the protocols which accept it (like echo),
- can repeat the test and display various measures about it,
- can use T/TCP on systems which support it.
It's useful for checking that http servers are running and not wedged.
ENet's purpose is to provide a relatively thin, simple and robust network
communication layer on top of UDP (User Datagram Protocol). The primary feature
it provides is optional reliable, in-order delivery of packets.
ENet is NOT intended to be a general purpose high level networking library that
handles authentication, lobbying, server discovery, compression, encryption and
other high level, often application level or dependent tasks.
hinfo is a utility that will display information about a host. It is
primarily designed to find the owner of an IP block in order to direct
spam complaints to where they may do some good.
(maintainer's note: the DATAFILES are updated without the port version
necessarily being updated. Expect drift on distinfo. See hinfo-update.)
Although the home page of the software is at www.blars.org/hinfo.html,
that page is not reachable from the FreeBSD.org domain.
