["Zhao Yongming (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-3181?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14203965#comment-14203965 ] 

Zhao Yongming commented on TS-3181:
-----------------------------------

for example, we should try to filter out these issues with cluster enabled:
{code}
[Nov  7 15:28:21.428] Manager {0x7f277bfff700} NOTE: [ClusterCom::drainIncomingChannel] Unexpected message on cluster port.  Possibly an attack
[Nov  7 15:28:57.501] Manager {0x7f277bfff700} NOTE: [ClusterCom::drainIncomingChannel] Unexpected message on cluster port.  Possibly an attack
[Nov  7 15:34:09.624] Manager {0x7f277bfff700} NOTE: [ClusterCom::drainIncomingChannel] Unexpected message on cluster port.  Possibly an attack
[Nov  7 15:38:36.235] Manager {0x7f277bfff700} NOTE: [ClusterCom::drainIncomingChannel] Unexpected message on cluster port.  Possibly an attack
[Nov  7 15:39:45.596] Manager {0x7f277bfff700} NOTE: [ClusterCom::drainIncomingChannel] Unexpected message on cluster port.  Possibly an attack
{code}

> the manager ports, such as 8088 8089 etc shoud only accept local network connections, and by ignore all the connections from outer network, we can make the interactions more stable.
