thanks for the reply, I have mythtv installed, after upgrading to hardy 
and option became avaiable in the mythtv control center, where you can 
have the master backend run as a diskless server, I enabled that and 
built an image (not knowing what the techonlogy behing it is :).

The package ltsp-server is installed, if i try to remove it, it tries to 
remove the packages mythbuntu-diskless-server, so it is mythbuntu 
running that service on port 2000 as for why the /opt, well ltsp is not 
installed there, it just stores the images in /opt/.
but that still doesn't explain why going to the hostname:2000 in firefox 
or epiphany from an ubuntu machine gives me that exe file. I guess i 
need a good understanding of  how ltsp works and why it would return 
such a file, or is it a gecko thing maybe?

the diskless-server didnt work anyways! :S so i will remove the service 
for now and try setting it up later!

that was scary, but i discovered new things which i like, iftop, ntop, 
snort, ltsp ;)

thanks again
