remote power control

[thierry itty]

thanks to all who replied

about UPS, unfortunately we just bought a bunch of them, and they don't 
include this feature
about replacing the modem, the problem occurs with various makes and 
models (bewan, linksys, alcatel, netgear...)
about x10 devices, I'll add this as an alternative choice. it looks in 
fact cheaper, but it doesn't be quiet known in France
about atm circuit and network interface, I'll try and see at once if the 
models I have support this, if the problem can be solved using it, and 
how the server can manage that

btw we have 60 remote sites to handle and it takes up to 20% of a full 
time job just to go here and there to press a reset button, so it looks 
worth 100 or so bucks per site
