今天服务器收到大量集中连接（正常，非黑客攻击），但服务器出现许多类似PRINTK: 445 MESSAGES SUPPRESSED ,PRINTK:663 MESSAGES SUPPRESSED 这种错误信息，造成一小段时间无法连接，看了日志中printk...这段上下都没有其它异常，有知道是何原因的吗？

搜"服务器前台常出现的提示及含意"

NET: N messages suppressed.
服务器忽略了 N 个数据包.和上一条提示类似.服务器收到的数据包被认为是无用的垃圾数据数据. 这类
数据多是由攻击类的程序产生的.
这条提示如果 N 比较小的时候可以忽略.但如果经常或是长时间出现3位数据以上的这类提示.就很有可能
是服务器受到了垃圾数据类的带宽攻击了.

回复 #1 我是老新手 的帖子

应该是有问题，类似攻击
看看资源的消耗程度是多少

to 3楼：
我是 kernel: printk: 353 messages suppressed.
不是NET :** messages suppressed.
应该不一样吧！
