Hi,

Hmmm... Sorry for I couldn't image the usecase for such feature though, as
far as I know, ryu-manger will just wait for the connections from the
switch side and doesn't set timeout value.

So just an idea, writing a script like the following seems to be easy way.
1. invokes ryu-manager from this script.
2. sleep sometime
3. if ryu-mager didn't establish any connection yet, kill the ryu-manager
process.

To check if ryu-mager has connections or not, monitoring the specific
message works well I guess.

Regards,
Iwase
