The seccure toolset implements a selection of asymmetric algorithms
based on elliptic curve cryptography (ECC). In particular it offers
public key encryption / decryption, signature generation /
verification and key establishment.
ECC schemes offer a much better key size to security ratio than
classical systems (RSA, DSA). Keys are short enough to make direct
specification of keys on the command line possible (sometimes this
is more convenient than the management of PGP-like key rings).
seccure builds on this feature and therefore is the tool of choice
whenever lightweight asymmetric cryptography -- independent of key
servers, revocation certificates, the Web of Trust or even
configuration files -- is required.
Intel's Active Management Technology is a simple embedded subsystem
that helps you manage remote servers. In particular you can power off
or reset a remote system, regardless of the state of the operating
system.
amtc is a tool to efficiently monitor, power-control on a scheduled
basis and interactively manage a bigger bunch of PCs equipped with
Intel vPro technology, distributed over several rooms. Having a
practical tool for this purpose massively eases system management
procedures, from scheduled, unattended OS-re-installs to individual,
interactive remote power management needs.
djmount is a UPnP AV client. It mounts as a Linux filesystem the media
content of compatible UPnP AV devices.
Djmount discovers automatically all UPnP AV Media Servers on the network,
and make the content available in a directory tree. All shared files
(e.g. Audio or Video files) are directly visible and can be played using
your favorite media player.
djmount is written in C for the Linux operating system.
It is free software, licensed under the terms of the GNU General Public
License (GNU GPL).
NFSping is a command line utility for measuring the response time of an NFS
server. It's basically a copy of the fping interface but doesn't share any code
with that project.
On modern NFS servers, the network stack and filesystem are often being run on
separate cores or even hardware components. This means in practise that a fast
ICMP ping response isn't indicative of how quickly the NFS filesystem is
responding. This tool more directly tests the responsiveness of the server's
operating system's NFS component.
Oak is a program that can be used to monitor syslogs from a collection
of servers and notify operators when problem conditions arise. In
addition to providing immediate notification of critical problems oak
will also batch less critical problems into summary messages that can
be sent less often and via any medium. For example you may wish to
have oak page you on critical events while sending a summary of less
important messages to your terminal once an hour. In addition you
could send a daily email message summarizing all events.
Munin network-wide graphing framework (node)
Munin is a tool for graphing all sorts of information about one or more
servers and displaying it in a web interface. It uses the excellent
RRDTool (written by Tobi Oetiker) and is written in Perl. Munin has a
master/node architecture. The master connects to all the nodes at regular
intervals, and asks them for data. It then stores the data in RRD-files,
and (if needed) updates the graphs. One of the main goals have been ease
of creating own "plugins" (graphs).
This is the collector. It is installed on the machine that shall collect
and display performance data.
reslog resolves IPs in Apache(8) log files. The result can then be analyzed
by another program, like Analog. You can think of it as a replacement of the
Apache(8) HostNameLookups directive, in the sense that it resolves client
IPs altogether once a day.
Resolving takes long time. This is mainly caused by resolving: Network
packets may be filtered by firewalls; DNS servers may not be correctly
configured; may not be up working; may sit in slow network sections; may be
old slow machines; may have traffic jam... etc. All these reasons are out of
our control.
HATop is an interactive ncurses client and real-time monitoring
statistics displaying tool for the HAProxy Unix socket.
HATop's appearance is similar to top. It supports various modes for
detailed statistics of all configured proxies and services in near
realtime. In addition, it features an interactive CLI for the haproxy
Unix socket. This allows administrators to control the given haproxy
instance (change server weight, put servers into maintenance mode,
etc.) directly out of hatop (using keybinds or the CLI) and monitor the
results immediately.

This are the common components to drive both the server and the node components
of munin.
