- show the last ports that hosts tried to open.
- search for packets logged from an host.
- search for packets logged for a given port.
- search for packets logged for a given user.
Installation
Settings up the database
To use it, create a mysql database ulogd, tape as root :
mysqladmin create ulogd
Next, populate the database using ulogd.mysqldump :
cat ulogd.mysqldump | mysql -u USER -p ulogd
Put your user and password in include/require.inc.

The database is not the standard mysql database for ulogd. It add a few tables and indexes to have thing work fast.
Settings up netfilter
If you don?t use EdenWall or NuFW, you need to configure your netfilter installation.
Now you can log into the database. To log bad packet you have to use use ULOG
iptables -A FORWARD -j ULOG --ulog-nlgroup 1 --ulog-prefix "badif"
Enhancements:

Databrid is a browsing, retrieval and manipulation tool designed for the novice to the expert user. Databrid works on MySql and Oracle Database (versions 8 and above although not all functionality in the Browser is available for the lower versions). The core functionality of Databrid revolves around the tabbed areas within the Databrid application. The four main tabs in the main screen of Databrid are: SQL Editor, Browser, File and Jobs.

## SQL EDITOR ##
The SQL Editor tab allows you to write and run SQL and PLSQL. The tab provides the ability to use one of more sql autocompletion, word and syntax highlighting editors with automatic case adjustment for keywords. Provided with each editor is a table for displaying SQL query results and a text output area to display DBMS_Output output. Jobs can be run in the background allowing for the execution of multiple statements at any given time.

## BROWSER ##
The Browser tab allows the you to browse various parts of the database schema. The browsing is done via a particular schema user and displays information on tables, views, sequences etc. Features include the generation of database creation statements for tables, views etc, browsing table or view data, truncating tables, etc.

## FILE ##
The File tab allows you work with a CSV (comma delimited text file) and the database without having to load the CSV into the database. This tab has two areas that functionality: CSV Update and Database Update. CSV Update allows you to add additional columns to a CSV using a Select statement, including binding CSV column values to the Select statement. Database Update allows you to update the database using insert, updates, deletes or PLSql by binding the CSV column values into your statement.

## JOBS ##
This tab allows you to view which jobs are currently running or have finished. Jobs that are running can also be stopped.

Large Database Backup is a PHP class can be used to backup large MySQL databases into multiple files.

It can list the tables of a given MySQL database and generate SQL statements to create and insert records with the current values of the table rows, as if it was creating a new database. The class stores the generated SQL statements in files.

A full backup process can be split in multiple iterations to not exceed PHP default script execution time limit. Each iteration dumps a limited number of table rows. An iteration can be executed by a script that redirects the page request to itself at the end to proceed to the next iteration.
