Linux----rpm -ivh下载包出现库找不到类似libc

在做实验时，老师叫我们在FC12系统中下载telnet，安装telnet之前就得安装xinetd，但是当使用以下命令安装xinetd时，却出现以下错误：

root@localhost hsw]# rpm -ivh xinetd-2.3.14-20.el5_10.i386.rpm 
warning: xinetd-2.3.14-20.el5_10.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

询问同学，只要加上一个--nodeps选项即可！

然后以相同命令安装telnet也行了！
