适用场景

  • Data ONTAP 7-模式
  • 克劳德克
  • CIFS

问题描述

  • 启用 Fpolicy 会导致 CIFS 访问延迟, etc/messages 日志中可能会显示以下消息

[fpolicy:cifs.server.errorMsg:error]: CIFS: Error for
server \\<VSERVER>: Error while negotiating protocol with server STATUS_IO_TIMEOUT.
[fpolicy:fpolicy.fscreen.server.connectError:error]: FPOLICY: An attempt to connect to fpolicy server \\<VSERVER> for
policy varonis failed [0xc00000b5].

  • 数据包跟踪显示 Fpolicy 服务器报告KRB5KRB_AP_ERR_MODIFIED 以响应会话设置
    • 使用加密的 Kerberos SMB2 会话设置请求 SMB2 etype: eTYPE-ARCFOUR-HMAC-MD5 (23) 失败
      KRB Error: KRB5KRB_AP_ERR_MODIFIED
