Hi All,
I am new to RYU having previously been using POX as my SDN Controller. One of
the first things that I've noticed when running RYU from my linux command line
is that when I quit RYU with Ctrl-C I get the following exception reported
back...
[root@localhost bin]# /usr/local/bin/ryu-manager
loading app ryu.controller.ofp_handler
instantiating app ryu.controller.ofp_handler of OFPHandler
^CTraceback (most recent call last):

KeyboardInterrupt
[root@localhost bin]#
RYU doesn't appear to have any handling for the KeyboardInterrupt signal. Is
this correct or is there a better way to shutdown RYU? I'd rather not see an
exception on program close.
Regards,
Alan.
