请问有没有遇到rpm 运行报错的问题？

可能是下载过程中文件被修改或者缺失，或自己的pc上传到安装的pc过程中文件被修改或者缺失；试试pc上用ftp方式去拷贝文件：

ftp> get xinetd-2.3.14-31.fc12.i686.rpm

local: xinetd-2.3.14-31.fc12.i686.rpm remote: xinetd-2.3.14-31.fc12.i686.rpm

227 Entering Passive Mode (192,168,2,134,13,162)

也许转文件的流格式不对，用asc码方式会造成文件被修改，修改SSH的流方式为2进制或许有效果
