Yes. But we do not supply the tools. You must download them yourself.

I have never tried via SSH, so I do not know if that works.
GdbServer does work on windows.

Having said that, I only tested Window to other Windows.
If you do Linux to windows you need to test if your local gdb can open 
the windows exe for symbols (afaik it needs a copy of the windows exe). 
Theoretically this should work. Again this kind of gdb stuff, you need 
to find gdb support / gdb mail list....


You must download it (e.g. from mingw), maybe also download any dll it 
needs (some versions need dll / It will pop up a notice, if it does).

There are some notes here.

All else google the docs for gdbserver.

Lazarus 1.2 supports this (but likely with some limitations), But 1.3 
has improved support.
