Controller & network nodes running RHEL 6.5. Compute node running CentOS 6.5. Neutron & Nova installed on compute node just fine, but I can't access the controller node. For example:

keystone --debug user-list

DEBUG:keystoneclient.session:REQ: curl -i -X POST http://tm1cldctll01:35357/v2.0/tokens -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: python-keystoneclient" -d '{"auth": {"te nantName": "admin", "passwordCredentials": {"username": "admin", "password": "pass-admin"}}}' INFO:urllib3.connectionpool:Starting new HTTP connection (1): 8080 Authorization Failed: Unable to establish connection to http://tm1cldctll01:35357/v2.0/tokens [NEW:note: root@tm1cldcmpl03 on parent: /root] #

This looks very suspicious. I have another controller node running RHEL 6.5, and it works OK. The HTTP connection info, though, looks different:

DEBUG:keystoneclient.session:REQ: curl -i -X POST http://xxxctlxxx:35357/v2.0/tokens -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: python-keystoneclient" -d '{"auth": {"tenantName": "admin", "passwordCredentials": {"username": "admin", "password": "pass-admin"}}}' INFO:urllib3.connectionpool:Starting new HTTP connection (1): xxxctlxxx DEBUG:urllib3.connectionpool:"POST /v2.0/tokens HTTP/1.1" 200 7939 DEBUG:keystoneclient.session:RESP: [200] {'date': 'Sat, 10 May 2014 00:42:20 GMT', 'content-type': 'application/json', 'content-length': '7939', 'vary': 'X-Auth-Token'}

Any idea why the differences?
