我的root密码很简单, 机子几乎整天连在网上,请问容易被入侵吗?谢谢

家的电脑基本上是365X24上网（adsl动态IP），root的passwd15位以上，开了ssh

我每天都能看到很多通过ssh连接我的电脑的。

可以看到频率还是相当高的。以下是6月份的记录：从以下记录可以看出有很多无聊的人天天在网上进行端口扫描，只要发现在开改的ssh端口，就用字典攻击。我没有改ssh的default端口22，(以前改成2222后就少了很多，后来还是改回22了)

所以基本上,使用ssh的童鞋,务必要用denyhosts一起配置着使用。

ssh没用过，
是不是用/etc/init.d/sshd status查看是否开启？
我的gentoo是当个人桌面用的，没用过远程登录。

你在路由后面，不做特殊的端口映射自己在办公室想连回家里都不行，别人就更连接不了，扫描也无从谈起。

我在路由器的设置中映射了一些端口

相信不包括 ssh 的默认端口。

gentoo 我用固定地址192.168.2.100  端口60005－60009，是给rtorrent用。
这样安全吗？谢谢

没什么问题。
