Fun with F-Spot 0.8.0 and sqlite3

Today I focused on the F-Spot version 0.8.0.
I knew that contains a database that keeps information about the pictures.
I found the database and tried a few commands:

$ cd .config/
$ cd f-spot/
$ ls
addin-db-001  photos.db

Once I found the database, I started SQLite3. See the example below:

$ sqlite3  photos.db 
SQLite version 3.7.2
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .tables
exports         meta            photo_versions  rolls         
jobs            photo_tags      photos          tags          
sqlite> .schema photos
CREATE TABLE photos (
 id   INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, 
 time   INTEGER NOT NULL, 
 base_uri  STRING NOT NULL, 
 filename  STRING NOT NULL, 
 description  TEXT NOT NULL, 
 roll_id   INTEGER NOT NULL, 
 default_version_id INTEGER NOT NULL, 
 rating   INTEGER NULL 
);
CREATE INDEX idx_photos_roll_id ON photos(roll_id);
sqlite> select * from photos;

It is easy to use and implemented various python scripts.

Linux and denial of service - DoS

A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users.
We can see more on the wiki web page.

On Linux we can see if an attack is attempted with this:

netstat -ant | grep SYN_RECV | wc -l
This is an indication of a denial of service (DoS) attack against your system's X port.

It is likely one attack against a public service such as a web server or mail server.
