Actually, are you sure that the iButton and the Schlumberger JavaCards
use
the same file format ? I would expect, that their converters create
different
file formats, e.g. you can not use the converter shipped by
Schlumberger.
Although the JavaCard 2.1. specification with a standard JavaCard file
format
has been released, there does not seem to exist any compliant
implementation so
far.
However, I would guess that the iButton people implemented the converter
in
Java ("the big thing") and that they use native code only for the lower
level parts of the communication and you could therefore use their
converter under Linux as well.
Hope this helps.
