Free dia software for linux

Dia is designed to be much like the commercial Windows program Visio. It can be used to draw many different kinds of diagrams.

Dia project currently has special objects to help draw entity relationship diagrams, UML diagrams, network diagrams, flowcharts, and simple circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to EPS or SVG formats and can print diagrams (including ones that span multiple pages).

AutoDia is a modular application that parses source code, XML or data and produces an XML document in Dia format (or images via graphviz and vcg). AutoDias goal is to be a UML / DB Schema diagram autocreation package.
The diagrams its creates are standard UML diagrams showing dependancies, superclasses, packages, classes and inheritances, as well as the methods, etc of each class.
AutoDia supports any language that a Handler has been written for - see below for an up to date list..
Autodia now outputs the following formats :
- Graphviz (using dot to generate jpg, png, etc)
- dot
- vcg
- xvcg (using xvcg to output postscript, etc)
- dia (using a new custom directed graph algorithm to layout diagrams)
- HTML/XML/Anything (if you write your own template)
- Experimental SpringGraph (native perl directed graphs similar to graphviz) now included
- Experimental Umbrello XML/XMI (requires fixing)
Autodia now parses the following forms of input
- Perl
- Python
- PHP
- Java (some issues with version 1.4) no longer fully supported (it used to work, Java broke its APIs now it doesnt, fixes welcome)
- C++
- Torque (XML DB schema)
- DBI (perl database interface handles)
- SQL
- Umbrello (experimental)

Yet Another dia2sql is a tool that generates SQL statements from Dia XML files.

yadia2sql is intended to process diagrams that are compatible with dia2sql.php to some point, and provide features that would allow generation of SQL code for different database systems from single Dia source.

Usage:

yadia2sql.py [OPTIONS...]

Options:

-h | --help | -?
Prints short usage and copyright information.
-i filename | --input filename
Specify input file (must be an uncompressed Dia XML file).
-o filename | --output filename
Specify output file.
-p "text" | --pk-append "text"
Append text text to primary key definitions.
-f "text" | --fk-append "text"
Append text text to foreign key definitions.
-t "text" | --tbl-append "text"
Append text text to table definitions.
-m filename | --map-file filename
Specify substitution map file.
-d database | --database database
Specify database system (currently only mysql is supported).
If no input/output file is specified, stdin/stdout is used.

DiaDBDesigner is a standalone module for constructing databases with the help of the diagram creation program Dia.

In an easy to use environment, with DiaDBDesigner you can join multiple diagrams together to form one model of interconnected tables.

Medoosa is an application which creates UML class diagrams from C++ sources.

Corrections can be made interactively in a diagram editor (Dia) and are fed back into the source as Javadoc-style comments.

At this time, the layout must still be done by hand. Some code is already present to produce the layout with Graphviz.

Kivio is a flowcharting and diagramming application for the KOffice application suite, and has an userinterface that is similar to Visio.
Kivio project is fully integrated into KOffice and can for example be embedded into KWord.
Main features:
- Scriptable stencils using Python.
- Support for Dia stencils.
- Plugin framework for adding more functionality.

smspasswd software provides two factor authentication via cell phone short message service (SMS). The reason I wrote this was because of all the pesky SSH brute force attacks, which continue to build in numbers. I didn’t want to waste money and time on using tokens because the few people who have accounts on my machines also have mobile phones.

I’m stoked that I have been using this since v0.1 back in 2005 and so far it’s worked very well with no changes. I’m hoping for feedback to get me motivated to develop this some more. Thanks to my good friend Solomon who has encouraged me to start posting some of my fun projects on the web.
Any feedback is more than welcome to ed -at- e-things.org.

How does this work?

The simple explanation for the average user goes a little like this. You use your normal password followed by a 6 digit number. To get access to a system you need to send an SMS from your pre-registered mobile phone number with a PIN. The systems admin folk will assign you a 4 digit pin and give you the mobile number to send your login request to. So, when you want to login, just send a text (SMS) to the phone number provided, with your 4 digit PIN. Shortly after you will receive a 6 digit number in a text (SMS) to your phone. Then login as normal using you normal password followed by the 6 digit number. You can use this same 6 digit number as many times as you like within a time period set by the systems admin folk. Simple right? Ok then, perhaps not much more complex than a token?

Now for the spanner-head explanation. smspasswd is a Perl application that runs as a daemon. It uses a MySQL back-end database which stores the usernames, mobile numbers, PIN’s, passwords, tokens, and the amount of time each users token (temporary x digit code) is valid for. smspasswd uses the information in the MySQl database to update your LDAP server based on a polling frequency you set in it’s config file. You can also set lots of other options in the config file and these are covered in the Features section below. smspasswd talks to a SMS gateway to send and receive new token requests. In my case it’s a cheap pre-paid Nokia 7110 connected to COM1 (/dev/ttys0) via gnokii.

The authentication process goes a little like this. The user sends a SMS to your gnokii phone with their PIN. Note the PIN is not really important because it will get saved in the users SMS outbox, so it could just be “request” or “foobar”. What’s important is that the SMS must come from the correct number for that user, and even if this could be spoofed, the reply will still go the users mobile number in the database anyway. Then smspasswd checks the database for the users mobile phone number and if it finds a match it will send a x digit code to the number registered for that user. At this point the password for this user will be updated in the local LDAP server with their normal password, followed by their new x digit code. Once the user has the SMS with the new code they can login.

You should setup your systems and applications for LDAP authentication, and if you wish you can configure your FreeRADUIS server to authenticate via OpenLDAP. Or you can use some commercial LDAP or RADIUS system. FreeRADIUS and OpenLDAP work just fine for me.

Confused? Drop me an email and I’ll make a nice diagram with Dia.
