Hi, There is an uncaught exception (Python3 only) when Ryu responds to a HELLO message because the OF version is incompatible. The Ryu app specifies that it is interested in OF 1.3 only, and the exception occurs when an OF 1.0 switch connects.
Ref: https://github.com/faucetsdn/faucet/issues/1665 I've attached a patch that fixes the uncaught exception issue. Also: Ryu leaves the OF connection open after responding to the hello failed message. The connection appears to remain in the HANDSHAKE_DISPATCHER state. What is the best way to close the connection? Regards, -Bill
