BleachBit deletes junk to recover disk space and maintain privacy. It rids your system of old junk including cache, Internet history, temporary files, unused locale files (better than localepurge), logs, and cookies. Designed for Linux systems, it wipes clean 50 applications including Adobe Reader, Bash, Firefox, Flash, OpenOffice.org, Opera, Real Player, Skype, and more. It shreds files so that they cannot be recovered, and it wipes free disk space to hide insecurely deleted files. It offers both a simple PyGTK GUI and a command line interface for automation.
Freedup finds and eliminates duplicate files by linking them, and thus reduces the amount of used disk space within one or more file systems. By default, hardlinks are used on a single device, symbolic links when the devices differ. A set of options allows you to modify the methods of file comparison, the hash functions, the linking behavior, and the reporting style. You may use batch or interactive mode. Freedup usually only considers identical files, but when comparing audio or graphics files, you may elect to ignore the tags.
Path Analyzer Pro integrates advanced traceroute software (based on the open-source tool LFT) with performance measurements, DNS, whois, and specialized network resolution to help investigate network issues. It also supports geolocation, and can plot network paths on a map. People use it to research IP addresses, email addresses, and network paths, to graph protocol latency, jitter, and other factors, and to locate firewalls and other filters that may be impacting your connections.
sdparm has a command line interface for getting and setting SCSI mode page fields. Fields can be referred to by an acronym or a numerical address. It has support for various SCSI transport and vendor-specific mode pages. It also decodes Vital Product Data (VPD) pages and can send some simple SCSI commands. sdparm was originally written for Linux with ports to FreeBSD, Solaris, Tru64, and Windows.
StableNet Express can comprehensively monitor an entire network, including the system and application environments. It features an easy-to-follow graphical display which provides a live view of what is going on in a networked IT system. The automatic discovery functions allow the entire monitoring system to be up-and-running within only a few minutes. Nothing needs to be installed on the production systems. It can be extended by users with their own measurement and alarm modules by adding scripts into a specific folder.
The svnmailer is a tool that is usually called by a subversion hook to submit commit notifications in various ways (at the moment: mail via SMTP or a pipe to a sendmail like program, news via NNTP, or CIA live tracker notification via XML-RPC). It is derived from the original mailer.py distributed with subversion, but should be much more consistent, more extensible, and have many more features.
Config::Maker takes a file with data in simple hierarchical format (similar to BIND and DHCP configuration files) and several templates, and produces the text by filling in the values. It is mainly useful for creating related configuration files. It can be used to generate firewall configuration scripts, DNS zone files, DHCP configuration files, a reference from a single file with all users and machines, etc. It's useful when you are not satisfied with keeping information synchronized in several places, but don't want something as complex as cfengine. Snippets of Perl can be used if all else fails.
logmine.pl parses a Common Log Format (CLF) log file from a Web server and generates a report of the relationships between the countries, IP addresses, and URLs that were visited. Specific URLs and patterns may be specially excluded from the report. It also supports listing only hits from certain geographical locations.
