There's no supported way to simply reset a DTU.
However, a trick I sometimes use which works today is what is known as
"poisoning the ARP cache" :). Not as dangerous as it sounds.
If for example the DTU that you want to reset has address 10.1.2.3, you
can set the ARP cache for it to a fake MAC address, as follows:
# arp -s 10.1.2.3 01:02:03:04:05:06
After a couple of minutes, the DTU will reset.
This works because it fools the system into thinking it should send
heartbeats for the DTU to a non-existent address. After receiving no
heartbeats for a while, the DTU tries resetting to see if it can resolve
whatever issue has arisen. When booting, the DTU will broadcast its
correct MAC address, and "heal" any poisoned ARP cache entries to the
correct MAC address.
It's not user-friendly, it takes a little while, but it does work if
you're in a pinch.

Thank you very much,
but I need to reset the DTU
and not only the user session.
Is possible reset the DTU as
switching off the current from command
line?
Thanks

Hi,

instead resetting DTU with PC kbd?
I have to reset DTU Sun from a script launched inside
Kiosk session when an application is closed.
Thanks
