今天在linux群中有人想做个脚本每天将日志发到自己邮箱中，我登陆我公司邮件服务器看，突然发现日志Jul 28 16:35:42 mail sshd[4416]: Failed password for root from ::ffff:218.5.2.247 port 47560 ssh2

这家伙不停的SSH我服务器，还好密码长，“？密码有多长呀？” ，长到有时候自己也记不住了。哈哈，我马上看了一下/etc/hosts.allow原来上次用的时候忘记关掉了，于事我马上更改设置，我就用最简单的/etc/hosts.allow /etc/hosts.deny 配置一下就搞定了。技术不难，我就奇怪的事，还真有人喜欢玩GJ呀？
