Hi,
I can start , stop , pause the trace remotely. I am also able to save the
trace on local machine (target-mips board). I am unable to save the trace
on remote machine. I get the following error.
> lttctl_client ltt_control writeTraceNetwork "kernel" "0" "traceTest"
"/home/techie/Desktop/tracetest" 2 false false false
Reply error 131077: Channel closed
