我是不是被入侵了?怎么办?
晚上9点多钟，硬盘狂响不停，切换至终端，显示很慢几乎不能用终端登录!只好Powner it!今天是第二次了。说明:Redhat 9.0；个人ADSL上网用户；cornd服务没开；系统安全日志如下；平时用init 3登录；菜鸟一只。Sep 24 17:19:55 localhost sshd: Server listening on 0.0.0.0 port 22.

顺便问一下sshd是什么?如果是入侵的话，我调高防火墙(不过好像是最高的)，会不会有用?终于应该怎么办?
还有会gnome会出来个正在搜索硬盘...的对话框，无任何内容 没事的，是updatedb，扫描你硬盘文件，方便你find
