PBS Communication Error: Nodes can not communicate

Question

我成功安装了 pbs 服务器，启动了服务，可以使用 pbsnodes 命令查看节点。队列在 qstat -q 命令中正确显示。在我提交测试作业后，以下内容出现在我的 sched_log、server_log 和妈妈节点 mom_log 文件中：

sched_log:

如何解决这个问题？是由于任何类型的身份验证失败吗？在那种情况下，我应该设置 ssh 密钥身份验证登录吗？

有趣的是，我有另一台带有 Torque 的服务器，名为 headnode2，ip 为 .89.231，但没有显示任何错误。我没有按照任何额外的步骤来配置那个。

Answer 1

您可能只需要配置防火墙。我会运行

# iptables-save > iptables.bak && iptables -F

在服务器和一个测试节点上，然后向该节点提交作业以查看是否运行s。
