自动阻止SYN、DoS攻击
除了告警敦促人工处理SYN、DoS攻击，可以将嫌疑犯先抓起来再说：
netstat -na | grep :80 |awk '{print $5}'|awk -F '::ffff:' '{print $2}' | grep ':' | awk -F: '{print $1}' | sort | uniq -c | sort -r | awk -F' ' '{if ($1 > 50) print $2}' | sed 's/^.*$/iptables -I RH-Firewall-1-INPUT 1 -p tcp -m tcp -s & --dport 80 --syn -j REJECT/' | sh
该脚本基于的基础是认为从一个IP过来的连接数过大（超过50个），则该IP可能在进行攻击。实际上可能误杀掉一些只能通过代理服务器访问的大公司用户，或者某些有点贪心的网络爬虫。可以在脚本中加入一些白名单以防止误杀，如：
netstat -na | grep :80 |awk '{print $5}'|awk -F '::ffff:' '{print $2}' | grep ':' | awk -F: '{print $1}' | sort | uniq -c | sort -r | awk -F' ' '{if ($1 > 50) print $2}' | grep -v xxx.xxx.xxx.xxx | sed 's/^.*$/iptables -I RH-Firewall-1-INPUT 1 -p tcp -m tcp -s & --dport 80 --syn -j REJECT/' | sh

自动短信提醒进行服务器状态告警
定时启动的脚本：
df | grep “/var” | awk ‘{ print $5 }’ | awk -F”%” ‘{print $1}’ | awk ‘{ if ($1 > 90){print “alert.sh \”139xxxxxxxx\” \”insufficient disk space on /var. “,$1,”\”"} }’ | csh
ps -ef | grep httpd | grep -v cronolog | grep -v grep | grep -v root | wc -l | awk ‘{ if ($1 > 3000){print “alert.sh \”139xxxxxxxx\” \”apache process “, $1,”\”"} }’ | csh
echo ‘show processlist’ | mysql | grep -v Id | grep -v processlist | wc -l | awk ‘{ if ($1 > 3000){print “alert.sh \”139xxxxxxxx\” \”mysql process “, $1,”\”"} }’ | csh
alert.sh 脚本:
echo $2
echo -e “From:monitor<>\nReply-to:support <support.labs@etentec.com>\nSubject:$2\n\n$2\n.” | /usr/sbin/sendmail $1@139.com

你把公司当什么？
联想又要裁员了，上次裁员的时候，有位员工写了篇《联想不是家》打动了很多联想人的心。每位职场中人可能都想过：“我把公司当什么”。
我想，首先公司不是家。对于绝大部分人来说，家是个温馨安全的港湾，你哪都去不了的时候，家总能包容你。而公司的文化再怎么追求人文，一旦经营不善就可能什么都不是。
很多人想创业，要追求自己的事业，为什么在公司就找不到自己的事业呢？作为员工来说，如果公司是你的家，你作为家庭成员应该想方设法把你的家建设好；如果你只是把公司当作赚生活费的地方，得过且过就行了。个人认为在很多公司里采取第二种想法的人应该是占很大一部分的。
其实对于很多公司经营的人来说，不管是不是老板，都有一种认同感，这种认同感并不完全在于薪酬、股权等利益上，而是公司提供了一个供他事业发展的平台。尤其体现在有活力的小公司里，在这样的公司里，每个人都能找到自己的位置，为集体作出最大的贡献。所有的有希望的公司都非常看重有激情的员工，这些员工都是公司的核心价值。所有的有希望的公司都注重给员工个体和集体提供共同发展的平台，这样的平台是公司的支柱。
公司是你个人事业发展的平台，你的成功源于此，你的失败公司帮你顶住。那么，你把公司当作什么？
