Zenoss is an enterprise-class network/systems management application. Zenoss project provides an integrated software package for monitoring availability, events, performance and configuration across layers (network, servers, applications, environment, etc.) and across platforms (Linux, Windows, Unix, etc.).
Main features:
- Organization-wide, IT infrastructure monitoring
- Scales to handle 10,000s of resources
- Integrated monitoring of availability, performance, events and configuration changes
- Across layers: network, servers, apps, environment...
- Across platforms: Windows, Linux, Unix ...
- Automated discovery and configuration modeling
- Role-based access through web portal
- Group-level views, settings and reporting
- Collection via SNMP, WMI, Telnet, SSH, Syslog
- Licensed under GPL
Enhancements:
- The only changes in this release from the 2.0.1 release are that we made changes to the pycom file to facilitate better WMI data collections.

EasySQL is a front-end that provides a slightly extended version of the MySQL SQL syntax allowing for far more sophisticated tasks to be accomplished without resorting to using an external language such as Perl.
Main features:
- Iterate across a SQL result set, and execute multiple queries using the values from each result row.
- Connect to multiple data sources and issue individual queries against one or more data sources.

archive2iso application takes a directory tree and randomizes the files in the tree to stripe the files across several ISO files that can be archived or burned off to a CD.

The intended use is to stripe files across multiple CD/DVD randomly so if one disc is damaged all the images that were in the same directory will not be lost since files are spread across multiple disks. The actual files themselves are not split, all files remain in their original state.

An example of an intended use is where you have a series of valuable vacation photos that could span 6 CD for all your photos in your collection. archive2iso would spread them out across the 6 CDs so if 1 of the 6 cds is lost, you only loose 1/6th of your images. Which is better than loosing all of them!

SYNTAX: ./archive2iso

EXAMPLE:

Enter Directory: /absolute/path - Files to archive = 910 - Estimated total Size = 632 MBEnter Max megabyte Size for the ISO/CD/DVD (1-4700): 100 - Estimated Num Disks = 7 /usr/tmp/disk_1.iso - 139 files at 99.6 MB /usr/tmp/disk_2.iso - 128 files at 99.8 MB /usr/tmp/disk_3.iso - 144 files at 99.9 MB /usr/tmp/disk_4.iso - 164 files at 99.7 MB /usr/tmp/disk_5.iso - 136 files at 99.9 MB /usr/tmp/disk_6.iso - 159 files at 99.9 MB /usr/tmp/disk_7.iso - 40 files at 32.8 MB Is the above disk configuration okay?Answer y or n: yNOTE: If the Disks do not look balanced then answer "n" and it will re-randomize. - Building ISO images

Earth allows you to find files across a large network of machines and track disk usage in real time. The project consists of a daemon that indexes filesystems in real time and reports all the changes back to a central database.
This can then be queried through a simple, yet powerful, web interface. Think of it like Spotlight or Beagle but operating system independent with a central database for multiple machines.
Earth is initially focused on managing the explosion of data that occurs in digital visual effects work.
Enhancements:
- Many small usability improvements, several significant performance improvements for the Web application, reduced database size, code improvements, and a much improved command line interface to the Earth daemon.

Apache2::ASP was developed in an attempt to address some of the problems associated with web application development in Perl.
Main features:
- Easy to install and get going.
- Requires only a small number of dependencies, each of which install automatically.
- Offers some structure without enforcing undue rigidity.
- Scales out instantly across multiple servers without requiring front-end proxies.

IP::Anonymous is a Perl port of Crypto-PAn to provide anonymous IP addresses.

SYNOPSIS

use IP::Anonymous;
@key = (0..31);
my $object = new IP::Anonymous(@key);
print $object->anonymize("192.0.2.0")."n";

This is a Perl port of Crypto-PAn. Crypto-PAn is a cryptography-based sanitization tool for network trace or log data. The tool has the following properties:

One-to-one

The mapping from original IP addresses to anonymized IP addresses is one-to-one.

Prefix-preserving

The IP address anonymization is prefix-preserving. That is, if two original IP addresses share a k-bit prefix, their anonymized mappings will also share a k-bit prefix.

Consistent across traces

Multiple traces can be sanitized in a consistent way, over time and across locations, even though the traces might be sanitized separately at different time and/or at different locations.

Cryptography-based

To sanitize traces, trace owners provide a secret key. Anonymization consistency across multiple traces is achieved by the use of the same key. The construction of IP::Anonymous preserves the secrecy of the key and the (pseudo)randomness of the mapping from an original IP address to its anonymized counterpart.

This Perl port of Crypto-PAn uses similar logic to that found in Crypto-PAn 1.0, but most importantly maintains consistency in the process so that regardless of implementation, using the same key in each will give consistent results.

USAGE

$object = new IP::Anonymous(@key)

Initializes the electronic codebook object with a 32 8-bit decimal array. This array, consisting of 32 decimals between 0 and 255 inclusive, is the user defined private key for this anonymization session. This 256 bit key should be kept private. The key can be used across sessions to maintain consistent mappings between the original and the anonymized IP addresses.

$object->anonymize($address)

Called with a dotted quad IP address string (e.g. 192.0.2.0). Returns an anonymized version of that IP address as a dotted quad string.

rsync is a replacement for rcp (and scp) that has many more features. It uses the "rsync algorithm" which provides a very fast method for remote files into sync.

rsync project does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.
