[vdr] check if vdr alive

[Juergen Schmidt <ju@ct.heise.de>]

Hello,

I need a way to check regularly, if vdr is still alive (and working!).
Ther are a couple of ways I can think of like

fuser /dev/ost/frontend0
echo "quit" | nc loclahost 2001

Is there a "recommended" way to check this?

bye, juergen

PS: As I'm running 2 instances of vdr, I have to check, I cannot use the
simple mechanism used in runvdr...
