Hi...

Just wanted to say that putting the script in /etc/init.d worked fine. The only thing is that then I used a tool "Sys V-init-Editor" to put the script distinct "run-levels" (I think I guessed the good ones).

I took a look on the website, but just the first paragraphs looked a little intimidating (many known things for me, at lease), so I will try afterwards with more time.

Thank you very much...

Another thing: How can I do to make X to detect my USB modem once it is running? I managed to make it work, but it only does it when it is connected before starting X...
