昨天晚上起床就发现网站上不去了，ssh 也连不上，心想不妙，去问网管，网管说是内网有个机子在 arp 欺骗，不过每次似乎总是这个原因，真有点怀疑真实性……
网管说等机子自动刷新完 mac 缓存就好了，如果实在着急，可以打电话重启机子。我等了一个小时，还是没好，无奈只好打电话去重启，这也是服务器自上架以来的第一次重启，之前服务器已经无故障平稳的运行了三百多天，不过服务器没什么负载也是真的，所以没什么可自豪的。
结果重启之后还是不行，心情一下跌倒谷底，在想服务器是不是启动失败了、硬盘坏道了、 CPU 烧掉了……越想越郁闷……
但是大半夜的也没发解决问题，只好先去吃饭，吃到一半，试了下发现网站都可以上了，顿时心情大喜，心想运气真是不错～
等我吃完饭，打算 ssh 连一下服务器，结果竟然是 connection refuse，顿时晴天霹雳，心想完蛋列，肯定是上次升级 openssl 之类的，导致 ssh 服务没有正常启动吧，ssh 启动不了，就啥也干不了了，难道这次真的得去跑机房了？
镇静了一下，忽然想到，原来 ssh 的默认端口号我改掉了，升级之后是不是端口也恢复成默认的了呢，马上尝试，OK! 连上～
再次欢呼～
一身冷汗啊，只要 ssh 不出问题，其他一切问题都好办，ssh 一挂，就只有跑路了……
下次 etc-update 的时候一定要仔细看了……
