cert-henu-p2p-speed教育网的速度

昨晚有人在学校网管群里抱怨校园网限速，限制p2p。作为cert教育网的忠实拥护者，截图（因为是PrintScreen直接截的图，电影内容看不到）一张，以证视听。可以看到，播放器右下角的即时速度为453KB/s。其实，峰值可以达到580多KB，不过是我按键的速度慢了点儿。

narrowad被黑导致xinhua被挂马

2009-03-24下午 18：36 google搜索图片过程中firefox挂掉了

还看到一个rundll错误的提示框，同时发现不明进程orz.exe（先前有听说过，但跟熊猫烧香一样从来没中过，汗……）
当时不太明白的是为什么xinhua网会被挂马，并且是2007-09那么古老的东西
后来一层一层的挖出来是广告商narrowad的问题。
比较有趣的是，在将近20点时，病毒被清除了，xinhua网上的广告恢复正常。（当时正在从2007-09到2009-03一页一页地测试）

还原后的恶性js脚本

疑问：
1.firefox下的flash插件早已升级，为什么还会出现这样的情况？
2.广告商是如何被黑？（很感兴趣……）以及，又如何恢复过来？

疑问1.的答案找到了，早期遗留下的旧版本falsh插件没有彻底清除，导致中马。惭愧……不过，给系统盘设置读写权限的做法很好地保护了俺免遭木马毒害。V

resume a background progress after logout(not ^z bg/fg)

here I'd like to share with you some useful tips I just founded while learning to set up a CS1.5 server on GNU/Linux. It's about how to resume a progress that had been put into background as you logout, and it's not the ^z and bg/fg stuff.

we have all come crossed such situations that we need to leave for a few seconds or just some unexpected things kicked us out from the system when we were still running a program, say 'nc -l -p 80'. This happens commonly when you are logging in with a not-robust connection, and when we get back, the the program is still there, running in the background. You can see it with a 'ps -A', but never will you be able to 'fg' it.

So, what shall we do?

The answer is 'screen'. With screen, you can safely "save" a running progress in the system, and "resume" it at any time. Following is the usage from 'man screen'.

SCREEN(1) SCREEN(1)

NAME
screen - screen manager with VT100/ANSI terminal emulation

SYNOPSIS
screen [ -options ] [ cmd [ args ] ]
screen -r [[pid.]tty[.host]]
screen -r sessionowner/[[pid.]tty[.host]]

-d -m Start screen in "detached" mode. This creates a new session but
doesn't attach to it. This is useful for system startup
scripts.

-S sessionname
When creating a new session, this option can be used to specify a
meaningful name for the session. This name identifies the session
for "screen -list" and "screen -r" actions. It substitutes the
default [tty.host] suffix.

And, examples I found at a GUN/Linux CS server howto.

"save a progress in background"

'screen -A -m -d -S hlds ./hlds_run -game cstrike +ip ip.de.internet +sv_lan 1 -nomaster +maxplayers 18 +map de_dust2'

"resume it whenever necessary"

'screen -r hlds'

To make it background again, Hold ctrl, then press and hold A, then press D.

keep an eye on Microsoft

Maybe we are all googlers, who hate Micro$oft and love GNU, but it is still necessary to watch Bill's huge company, world's largest software company.

向来喜欢标榜自己是google的忠实拥护者，努力用开源的GNU替代微软，然而还是很有必要留心比尔盖茨的大公司,世界上最大的软件公司～

the way to enable Google Search Wiki future

Happened to delete the old post, for I thought every body already knew how to enable Google Search Wiki. Yet, I was wrong, and it's still something new to most people. At least, you can't find the right answer at present when google "enable google Search Wiki". So I re-posted the article, renamed it from "how to start google Search Wiki" to "how to enable google Search Wiki", and add the Chinese text.
