Here you can find some tools that's I've developed under GPL, BSD like or Artistic licences and documentation under the Creative Commons BY-NC-SA licence.

Apache modules

ModProxyPerlHtml

Apache2::ModProxyPerlHtml is the most advanced Apache output filter to rewrite HTTP headers and HTML links for reverse proxy usage. It is written in Perl and exceeds all mod_proxy_html.c limitations without performance lost.

Apache2::ModProxyPerlHtml is very simple and has far better parsing/replacement of URL than the original C code. It also support meta tag, CSS, and javascript URL rewriting and can be use with compressed HTTP. You can now replace any code by other, like changing images name or anything else. mod_proxy_html can't do all of that. Since release 3.0 ModProxyPerlHtml is also able to rewrite HTTP headers with refresh url redirection. One of the common used of ModProxyPerlHtml is as free replacement for Microsoft TM ISA servers.

AuthenCacheLDAP Apache2::AuthenCacheLDAP is an advanced Apache2 / mod_perl2 authentication program (allow group auth + non standard LDAP schema + cache + single signon (SSO)). Last version include SSO logout.
AuthenCacheLDAP Apache::AuthenCacheLDAP, same as above but for Apache/mod_perl versions 1

Antivirus

SquidClamAv

SquidClamav is an antivirus for Squid proxy based on the Awards winnings ClamAv anti-virus toolkit. Using it will help you securing your home or enterprise network web traffic. SquidClamav is the most efficient Squid Redirector and ICAP service antivirus tool for HTTP traffic available for free, it is written in C and can handle thousand of connections.

Database

Ora2Pg

Ora2Pg is a free tool used to migrate an Oracle database to a PostgreSQL compatible schema. It connects your Oracle database, scan it automaticaly and extracts its structure or data, it then generates SQL scripts that you can load into your PostgreSQL database.

Ora2Pg can be used from reverse engineering Oracle database to huge enterprise database migration or simply to replicate some Oracle data into a PostgreSQL database. It is really easy to used and doesn't need any Oracle database knowledge than providing the parameters needed to connect to the Oracle database.

pgBadger

pgBadger is a PostgreSQL log analyzer build for speed with fully detailed reports from your PostgreSQL log file. It's a single and small Perl script that aims to replace and outperform the old php script pgFouine.

pgBadger is written in pure Perl language. It uses a javascript library to draw graphs so that you don't need additional Perl modules or any other package to install. Furthermore, this library gives us more features such as zooming.

pgFormatter

pgFormatter is a SQL formatter/beautifier supports keywords from SQL-92, SQL-99, SQL-2003, SQL-2008, SQL-2011 and PostgreSQL specifics keywords. May works with any other databases too.

pgFormatter can work as a console program or as a CGI. It will automatically detect his environment and output as text or as HTML following the context.

pgCluu

pgCluu is a PostgreSQL Cluster performances monitoring and auditing tool.

pgCluu is a Perl program used to perform a full audit of a PostgreSQL Cluster performances. It is divided in two parts, a collector used to grab statistics on the PostgreSQL cluster using psql and sar, a grapher that will generate all HTML and charts output.

Log analyzer / Reporting tools

SendmailAnalyzer

SendmailAnalyzer as is name suggest is a free Sendmail/Postfix log analyzer. It process maillog files and generate dynamic statistics in HTML and graphical output. The reports are generated in real time so that it let you know at any moment what is going on your mail servers.

SendmailAnalyzer is easy to install and highly configurable to match the dozen of Sendmail possible configurations. It also support report for all the major milter or sendmail filters like SpamAssassin, MailScanner, Clamav, Amavis, RBL check, J-ChkMail, etc. SendmailAnalyzer is really helpful for IT reporting.

SquidAnalyzer

Squid proxy native log analyser and reports generator with full statistics about times, hits, bytes, users, networks, top urls and top domains. Statistic reports are oriented toward user and bandwidth control; this is not a pure cache statistics generator.

SquidAnalyzer use flat files to store data and don't need any SQL, SQL Lite or Berkeley databases.

This log analyzer is incremental and should be run in a daily cron or more often on huge network trafic.

pgBadger

pgBadger is a PostgreSQL log analyzer build for speed with fully detailed reports from your PostgreSQL log file. It's a single and small Perl script that aims to replace and outperform the old php script pgFouine.

pgBadger is written in pure Perl language. It uses a javascript library to draw graphs so that you don't need additional Perl modules or any other package to install. Furthermore, this library gives us more features such as zooming.

SysAdmin tools

SysUsage

SysUsage continuously monitor your systems informations and generate periodical graph reports using rrdtool or javascript jqplot library. All reports are shown throught a web interface. SysUsage is design with simplicity in mind. I want all relevant statistics from my servers within an intuitive web interface and without spending too much time to configure it, if you know Nagios, you know what I mean. You will especially like SysUsage for that.

SysUsage grabs all system activities using Sar and system commands allowing you to keep tracks of your computer or server activity during his life. It is a great help for performance analysis and resources management. The threshold notification can alarm you when the system capabilities are reached by sending SMTP messages or throught Nagios reports.

SquidGuardMgr

SquidGuard Manager is a Perl CGI Web GUI for squidGuard and SquidClamav administration. It allow full administration of SquidGuard blocklist and ACLs. You can also manage graphicaly your SquidClamav configuration.

This program support all configurations directives of SquidGuard and SquidClamav without intrusive modification, i-e you can still edit the configuration files by hand before and after using SquidGuard Manager.

pgCluu

pgCluu is a Cluster performances monitoring and auditing tool but it can also be used as a single sar grapher tool.
