Config my server
All kid's tricks...
Today, I installed Ubuntu 5.10 on my PC, and meanwhile removed Red Hat Linux 9 which had been settling on my PC for about two years. Also set up a Apache web server, and successfully added a cron job that synchronize my dynamic IP with this domain - yass.3322.org every 5 minutes, so now you should be able to visit the web page at my yass, well, actually nothing there now... :)
With this server, I will be playing a lot of games, you know what game means.
Final words, APT (the Advanced Packaging Tool) is damn good! RPM sucks...
(Note: I'm only running an experimental server, no always online guarantee)

What a stupid mistake...
原以为设置的 cron 是每五分钟执行一次的，可后来发现间隔的时间要长得多，仔细想了想，原来如此：
我设置的 cron entry 是
5 * * * * [do a job]
真正的意思是：当时钟的分钟数到达5时执行，也就是说，每小时才执行一次，如果想要达到5分钟执行一次的效果，最直接的方法是添加12条类似的 entry
0 * * * * [do a job]
5 * * * * [do the same job as above]
10 * * * * [do the same job as above]
...
55 * * * * [do the same job as above]
或者用 RegExp 把12条语句压缩到一条里面？
Mmm... 一小时更新一次也好，用户名密码以明文方式传输，传输的次数越多危险系数越高……
