有人在不断尝试登录本机的smtp和imapd服务，有暴力破解的嫌疑。
需要看看出现的最多的这个地址是来自哪里的。

说明什么问题啊,

还有,

Jun 28 15:36:57 ttyt imapd[15456]: Command stream end of file, while reading line user=root host=[60.216.152.208]
Jun 28 15:36:57 ttyt imapd[15455]: Command stream end of file, while reading line user=root host=[60.216.152.208]

Jun 28 15:36:58 ttyt imapd[15457]: Command stream end of file, while reading line user=root host=[60.216.152.208]

是什么意思啊,

Jun 28 15:33:47 ttyt ipop3d[15371]: Login failed user=admin auth=admin host=[60.216.152.208]

ipop3d , smtp, imapd 登陆是怎么回事,,万一被登陆有什么后果. 服务器在这三个服务方面要注意哪些东西.

有没有好的防止暴力破解密码软件.

secure.1 里面怎么会有这样的记录呢

Jun 28 15:23:03 ttyt last message repeated 2 times 又是什么意思.

就是说有人在尝试登陆到你的系统，登陆进去了，你说能干什么，把你系统搞残是很easy的，还有至于如何防护，这不是一两句说得清的。好好看看吧
