Client programs that read, parse and process Argus data, and comprise
the client part of the Audit Record Generation and Utilization System.
Argus is a generic IP network transaction auditing tool that has been used
by thousands of sites to perform a number of powerful network management
tasks that are currently not possible using commercial network management
tools.
Argus runs as an application level daemon, promiscuously reading network
datagrams from a specified interface, and generates network traffic audit
records for the network activity that it encounters. It is the way that
Argus categorizes and reports on network activity that makes this tool
unique and powerful.
IOG is a network I/O byte grapher made to graph cumulative KB/MB/GB
totals for hours/days and months. It is intended to be simple, fast
(support thousands of hosts) and integrate well with MRTG. Data for
each host is updated hourly and HTML graphs are created. It uses a
data consolidation algorithm which allows for a small, non-growing
database file for each host. No external graphing libs or
executables are required.
IOG has been used in several production ISP environments,
including at the authors company, Dynamic Internet (dyni.net).

To ease the task of network administration,
decrease the likelihood of erronous command execution and
to maintain all network services from a central point,
EnderUNIX SDT anounces the availability of its 9th open-source tool,
netUstad.
It has been coded in C language and includes its own HTTP server.
The newly anounced version provides a web interface for
system administrators to add/delete/update FreeBSD IPFW and Linux IpTables
rulesets, manage routing table and network interfaces.
You can manage your Firewall via a TCP/IP connected remote PC, easily.

Net::IPAddr is a collection of helpful functions used to convert
IP addresses to/from 32-bit integers, applying subnet masks to
IP addresses, validating IP address strings, and splitting a FQDN
into its host and domain parts.
No rocket science here, but I have found these functions to very,
very handy. For example, have you ever tried to sort a list of IP
addresses only to find out that they don't sort the way you expected?
Here is the solution! If you convert the IP addresses to 32-bit integer
addresses, they will sort in correct order.
pmacct is a set of network tools to gather IP traffic
informations (bytes counter and number of packets); aggregation
of statistics is done using simple primitives (MAC addresses,
source host, destination host, ports and ip protocols) that can
be used alone or combined together to form complex aggregation
methods; counters are either global or historical (broken at
fixed timeslots). Data is either stored in a memory table,
pulled to stdout or in a SQL database (MySQL or PostgreSQL).
Gathering packets off the wire is done either using pcap
library (and promiscuous mode of the listening interface) or
reading Netflow packets coming from the network.
Slate: simple traffic analysis and data reporting collection server for LFAP
This package contains a small Lightweight Flow Accounting (LFAP)
server and LFAP API library. LFAP open solution to delivering
accounting data from Riverstone Networks Switches and Routers.
You can use the sfas program to obtain micro-flow information from
a Riverstone switch running either in Layer 4 bridging mode, routing
or MPLS LSPs. Data that can be collected includes everything from
an IPv4 header and UDP headers and the src/dst port from a TCP
header.
Transmission-daemon 是一个守护程序式样的 Transmission 会话,
可以使用 transmission-remote(包含在内)和其它比如 GTK+ 和
CLI 接口的 Transmission BitTorrent 客户端通过 RPC 来控制.
Transmission 已建成为一个轻量级、但不失强大的 BitTorrent 客户端。它简单、
直观的界面设计,可以轻松地和各种计算环境紧密集成。Transmission 在提供有用地的功能
和无限的功能膨胀间取得了平衡。此外,任何人都可以自由地使用和修改它。
bsdproxy is a generic, event-driven proxy designed specifically for the
BSD platform. It uses the kqueue()/kevent() system calls to determine
when to relay data from one side of the connection to the other. It also
uses GLib (http://www.gtk.org) data structures and memory management
functions to optimize steady-state performance (minimize unnecessary
memory allocation/deallocation).
bsdproxy has been used to proxy HTTP, HTTPS, telnet, and mysql without
any problems. It should be able to serve as a transparent proxy for
anything over a TCP/IP connection.
The guacamole-server package is a set of software which forms the
basis of the Guacamole stack. It consists of guacd, libguac, and
several protocol support libraries.
guacd is the Guacamole proxy daemon used by the Guacamole web
application and framework. As JavaScript cannot handle binary
protocols (like VNC and remote desktop) efficiently, a new test-based
protocol was developed which would contain a common superset of the
operations needed for efficient remote desktop access, but would
be easy for JavaScript programs to process. guacd is the proxy which
translates between arbitrary protocols and the Guacamole protocol.
GeoIP is a C library that enables the user to find the country that any
IP address or hostname originates from. It uses a file based database
that is accurate as of March 2002. This database simply contains IP blocks
as keys, and countries as values. This database should be more complete and
accurate than using reverse DNS lookups.
This module can be used to automatically select the geographically closest
mirror, to analyze your web server logs to determine the countries of your
visitors, for credit card fraud detection, and for software export controls.
This port includes a helper script, geoipupdate.sh, to help you keep the
library up-to-date.
