Thanks a lot but in my situation :

1. nohup seems not to be installed on my "reduced linux distribution".
It's a OpenWrt tunning on my WRT54GL Broadband router.

2. I have looked for the way I can "detach the screen" with Putty but
I've not found (May be you can precise ?)

3. The "fork daemon" script found on
seems to be as huge as my own script and little bit hard to undestand.

So maybe "detach the screen" ?
