我按照http://docs.openstack.org/developer/swift/development_saio.html上的说明在机器 1（Centos 6）上安装了 OpenStack Swift 服务。
我能够在同一环境中使用 curl 检索令牌。
curl -v -H 'X-Storage-User: test:tester' -H 'X-Storage-Pass: testing'http://machine-1IP:8099/auth/v1.0
* About to connect() to machine-1 ip port 8099 (#0)

如果我尝试从另一台机器（机器 2）访问它。我得到主机不可访问异常。我可以从 machine-2 ping machine-1。
curl -v -H 'X-Storage-User: test:tester' -H 'X-Storage-Pass: testing'http://machine-1IP:port/auth/v1.0

请建议为什么无法从远程机器访问 Swift REST 服务？我错过了配置中的任何内容吗？
