Hi,

Service is running. However it’s not listening port 9696.
/var/log/neutron/server.log is empty.
Any idea?

root at xxxxxx:~# service neutron-server status
neutron-server start/running, process 6926
root at xxxxxx:~# netstat -l |grep 9696
root at xxxxxx:~# telnet 127.0.0.1 9696
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

Can you check that neutron server is actually running?
It should create a listening tcp socket on the port 9696.
Can you also look at Neutron server logs? If there is some misconfiguration and Neutron server fails to start, logs could give a hint about what is wrong.

Thanks,
Eugene.

Hi,

I’m installing Havana and meet a problem when run command “neutron agent-list”.
root at i2052247:~# neutron agent-list
Connection to neutron failed: Maximum attempts reached
Actually it would have same failure when run any neutron command.
I found bugs https://bugs.launchpad.net/neutron/+bug/1211915 and https://bugs.launchpad.net/nova/+bug/1229475/comments/14. Workaround is “ Forcibly clear connection pool“.
Does anyone know how to clear connection pool on Neutron/Havana?
