Sshguard protects networked hosts from brute force attacks
against ssh servers. It detects such attacks and blocks the
attacker's address with a firewall rule.

Signing Party is a collection for all kinds of pgp related things,
including signing scripts, party preparation scripts etc.

caff is a script that helps you in keysigning. It takes a list of
keyids on the command line, fetches them from a keyserver and calls
GnuPG so that you can sign it. It then mails each key to all its email
addresses - only including the one UID that we send to in each mail.

pgp-clean takes a list of keyids on the command line and outputs an
ascii-armored keyring on stdout for each key with all signatures
except self-signatures stripped. Its use is to reduce the size of keys
sent out after signing. (pgp-clean is a stripped-down caff version.)

gpg-key2ps will output a PostScript file which has your Key-ID, UIDs
and fingerprint nicely formatted for printing paper slips to take with
you to a signing-party.

Given one or more key-ids, gpg-mailkeys mails these keys to their
owners. You use this after you've signed them. By default, the mails
contain a standard text and your name and address as the From (as
determined by the sendmail command).

gpglist takes a keyid and creates a listing showing who signed your
user IDs.

gpgsigs was written to assist the user in signing keys during a
keysigning party. It takes as input a file containing keys in gpg
--list-keys format and prepends every line with a tag indicating if
the user has already signed that uid.

keylookup is a wrapper around gpg --search, allowing you to search for
keys on a keyserver. It presents the list of matching keys to the user
and allows her to select the keys for importing into the GnuPG
keyring.

This is the community site for the Nagios Plugin for Cacti (NPC).

As a long time user of Nagios and Cacti I consider both applications crucial to understanding the health of my network, servers, and services. The purpose of NPC is to be a complete web based UI replacement to Nagios while fully integrating into Cacti using the Cacti Plugin Architecture. The primary benefit is a single point of access for trending and alert monitoring.

Nagios is excellent at reliably determining the status of network devices and services and Cacti is great at managing trending data via RRD's. Because Cacti has an extensible interface via the Cacti Plugin Architecture and decent user management it made sense to stick with Cacti's user interface. Both applications have tools and API's available now to make an integration project like this possible.

Plugin for backup and viewing of Cisco Routers (via telnet).

Provides a simple Syslog event search an Alert generation and notification interface that can generate both HTML and SMS messages for operations personnel who wish to receive notifications inside of a data or network operations center.

Eagle Mode is an advanced solution for a futuristic style of man-machine communication, in which the user can visit almost everything simply by zooming in. It has a professional file manager, file viewers and players for most of the common file types, a chess game, a 3D mines game, a multi-function clock and some fractal fun, all integrated in a virtual cosmos. Besides, that cosmos also provides a Linux kernel configurator in form of a kernel patch.

By featuring a separate popup-zoomed control view, help texts in the things they are describing, editable bookmarks, multiple input methods, fast anti-aliased graphics, a virtually unlimited depth of panel tree, and by its portable C++ API, Eagle Mode aims to be a cutting edge of zoomable user interfaces.
