I can't telnet into that port
nmeliasp at openflow:~$ telnet 208.77.78.155:6633
telnet: could not resolve 208.77.78.155:6633/telnet: Name or service not
known

Also when I run 
./nox_core -i ptcp:6633 routing

I get this output 
00001|openflow|WARN:stream: send error: Broken pipe
00002|nox|WARN:Error sending features request: Broken pipe

Okay, so in the case of a listener port the switch will bind on that port.

Can you do telnet <switch_ip> <tcp_port>

Where tcp_port coordinates to the port you used in the command below.

openflow <vlan_id> listener ptcp:<tcp_port>
