先看看系统日志。或者重新安装xinetd

重装xinetd包定能解决问题。
如果想研究一下，还是得看日志

hahasasa

in xinetd.conf
check "includedir /etc/xinetd.d"

已经解决了，谢谢大家

telnet对应的服务包都卸载了。
machine1:~ # rpm -qf /etc/xinetd.d/telnet
error: file /etc/xinetd.d/telnet: No such file or directory
machine1:~ # rpm -q telnet-server
package telnet-server is not installed
machine1:~ # ls -l /etc/xinetd.d/telnet*
-rw-r----- 1 root root 454 Sep 12 20:58 /etc/xinetd.d/telnet.rpmsave
machine1:~ #

如果要用就通过手工将telnet-server包安装上去。
将该包上传到目标机器，然后执行rpm -ivh telnet-server-1.2-134.22.x86_64.rpm进行安装。
然后修改/etc/xinetd.d/telnet、/etc/securetty等配置文件并重启xinetd服务解决(/etc/init.d/xinetd restart
)。
