[mythtv-users] Remotely monitor Backend is running

“Yes, please!” to your offer of a cut-down version. As I mentioned in my 
original post I piece and patch things together – not elegant but as 
long as it works! Will download your ‘Gaps’ for a learning experience – 
see what do understand.


I’m assuming the utility would be on my (local) computer and send 
inquires to the (remote) Backend. To me makes more sense in this usage 
to have Local send inquires to the Remote system: my script sends the 
“You there?” (SYN) and if doesn’t get an “Yup!” (ACK) puts up an error 
message window. (If the remote Backend is down/having problems it might 
not be able to send out a ‘help!’ message.)


Also if posted here could be used by others – seems like it would be a 
good utility to have just to monitor everything running properly rather 
sitting down at night to watch a show and being greeted with the “can’t 
find the Backend” screen.


Thanks!

Barry
