Nall is a small status icon application that
discreetly fits into the system tray. Its purpose
is to spawn a list of user scripts periodically
and display one line of output per script in a
tooltip window. Thus, it is possible to "monitor"
any kind of event that can be detected with a
script. Nall does not care about the return values
of the scripts it runs, but only displays their
output. It is also easy to interface nall with
Nagios plugins.

Opt-X is a network monitoring tool. Its features
include port monitoring, content monitoring,
creating server groups, dynamic creation of a port
list, tracking tasks, servers, vendors, and being
able to log changes that occur to a server.

Apt-zeroconf is a distributed apt-cacher for local
networks. It's called apt-zeroconf since it uses
avahi for automatically finding other apt-zeroconf
instances on the LAN, similar to Apple's
Rendezvous/Bonjour/Zeroconf technology.

OpenVPN Auth Passwd is a plugin that authenticates
OpenVPN users using the local passwd or shadow
files, using a privilege separation model. The
authentication method must be defined in the
Makefile prior to the compilation of the plugin.
On shadowed systems it uses the functions provided
in the shadow suite and, on other systems, the
getpwnam(3) function to verify the username/password.

Systemtap is a GUI to assist in the development of
Systemtap scripts and to graph the return values
of those scripts. It is intended to ease the use
of the Systemtap tool for Linux. It is both an IDE
for the scripting language and a data
visualization and analysis tool. The GUI is
targeted at system administrators who want to get
information out of their system using Systemtap,
as well as developers who wish to write new
scripts. It is an Eclipse-based application.

firewall_e is a small Web application which allows administrators to create lists of servers, users, and ports and assign them to each other. This allows an administrator to login, create users, and assign ports on servers for them to access. Users can login and their remote IP address will be stored. From this address, they'll then be able to access whatever services the administrator provided them.

arprelease is a small libnet-based tool to flush ARP
cache entries from devices like Cisco routers to
move an IP from one Linux box to another.

trackpeer is an agent that helps network and
server administrators with tracking their users'
computers. It makes it possible to determine the
MAC addresses of computers over a network, even
when the computers are behind NATed gateways. This
agent is intended to be used by the administrators
who need to identify and locate malicious
computers and virus-infected computers in a
network such as a middle-sized wireless LAN,
public Ethernet jack system, campus, or corporate
network.

Subnet Mask Calculator is a simple PHP script that
will return the subnet mask and slash-notated mask
for a given number of hosts.

NetCallback is a Java application permitting the export of TCP and UDP ports behind a firewall to hosts outside the firewall. This may be useful in some special cases, for example, centralized control of test (demo) networks, or connection to applets running in browsers. NetCallback consists of a public and a private server. The public server executes on a host outside the firewall and is responsible for receiving port forwarding requests. The private server is run on a host behind the firewall and is responsible for contacting the public server and connecting the protected TCP and/or UDP service to the public server clients. The connection between public and private servers may optionally be encrypted using SSL.

glTail.rb allows you to view real-time traffic,
data, and statistics from any log file on any
server with SSH, in an intuitive and entertaining
way using Ruby, net-ssh, and OpenGL.

DataMonitor is a Quartz 2D based plugin for
GlowWorm FW that displays network transfer
statistics in a visually appealing and unobtrusive
window using GlowWorm Statistics to obtain the data.

This script provides a simple way to monitor Ethernet link
status, and if the link goes down and up again, to kick the
DHCP client to try to renew its lease.

CronosEnbourg is a monitoring daemon for JMX, designed to target J2EE application servers like jBoss or WebLogic.

rrshd differs from rshd in that it ignores the
remote user's alleged identity and credentials,
and unconditionally runs local tasks as a specific
unprivileged user ("nobody" or similar). It will
only allow execution of programs listed in a
configuration file (/etc/rrsh.allow), and will
exec those programs directly without using an
intermediary shell of any kind. It also has TCP
wrapper support. These modifications make it a
good deal more secure than traditional rshd.
