I developed a number of software packages that can be downloaded from
JOde, pronounced jay-oh-dee-ee,
is a Java applet and desktop application which allows one to
interactively analyze systems of differential equations. It was
designed to be a convenient aid in teaching differential
equations. JOde page has been mirrored at several Universities,
a partial mirror geared for teaching systems of 2 differential
including some modifications and additional examples.

LinODE is a package for the free, open source
Computer Algebra System (CAS) called Maxima. It solves linear equations
with constant coefficients and Cauchy-Euler type equations, both homogenous
and non-homogeneous. It has a nice interface for solving boundary value
problems with these types of equations.
The package is meant primarily as a tool
for instruction. It is especially well suited for teaching engineering course
bases on the Kreyszig's book, as it has been tested on all examples in
Chapter 3 of the book.
