java.rmi.ConnectException：連接被拒絕托管： <public IP>

Question

我使用的是Cisco Netflow Collector軟件，它正在按預期方式收集Netflow數據，直到服務器管理員禁用iptables和服務器的安全管理員啟用防火牆為止。 現在，它給出了以下異常。

收集器在內部/專用服務器上運行，並且Cisco NFC許可證已綁定到公用ip，因此在/ etc / hosts文件中將主機名設置為公用ip。

sec管理員已允許端口22和1099，但是引發了以上異常。 我需要更改服務器或防火牆中的配置嗎？

通過使用使用專用IP生成的cisco的新許可證解決了此問題。 感謝Vishawanath和EJP的幫助。
