portsentry 和 IPTables 不断重启，但不知道为什么

Question

我一直在新服务器 [centos 5.7 Final] 上进行一些强化，我也有 logwatch，似乎得到了这些奇怪的日志

Commands Run:
User root:
   /sbin/service portsentry restart >/dev/null && /sbin/service iptables restart >/dev/null: 72 Time(s)

那么portentry日志是：

--------------------- PortSentry Begin ------------------------ 


 Ignored following ports
Advanced Stealth:
   TCP: ports: 21-22 25 53 80 110-111 113 135 137-139 443 932

Excluded following ports
Advanced: ports: 21-22 25 53 80 110 113 135 137-139 443

**Unmached entries**
72 Time(s): adminalert: Advanced mode will monitor first 1024 ports
72 Time(s): adminalert: ERROR: Socket 111 is in use and will not be monitored. Attempting to continue
72 Time(s): adminalert: Going into stealth listen mode on UDP port: 1
72 Time(s): adminalert: Going into stealth listen mode on UDP port: 111
72 Time(s): adminalert: Going into stealth listen mode on UDP port: 137
72 Time(s): adminalert: Going into stealth listen mode on UDP port: 138
etc etc ......   then
144 Time(s): adminalert: PortSentry 1.2 is starting.
144 Time(s): adminalert: PortSentry is shutting down
144 Time(s): securityalert: PortSentry is shutting down

 ---------------------- PortSentry End ------------------------- 

至少可以说，我有点困惑，如果我登录并手动启动 portsentry，我会得到关闭和启动的许可，所以我可以让它运行，只是似乎无法阻止它启动和停止在那之后。

我查看了 crontab，并且第一部分 [命令运行] 没有重复条目，该日志来自 cron。

如果其他人也遇到过这个，或者能给我一个线索，那就太好了。

谢谢

111 很可能是端口映射守护进程。为什么这个野兽要在你的服务器上运行？

如果您因为需要使用 NFS 客户端而需要它

PMAP_ARGS="-l"

在 /etc/sysconfig/portmap 中

这会将其绑定到本地主机。
