一.安装telnet 主机（服务器） [root@ruirui Packages]# rpm -q telnet telnet-0.17-47.el6_3.1.x86_64 [root@ruirui Packages]# yum install telnet* 二.修改telnet的配置文件，使得服务开启 [root@ruirui mnt]# vim /etc/xinetd.d/telnet
# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID disable = yes //这里将yes修改成no
}
三.关闭防火墙 [root@ruirui mnt]# service iptables stop 客户端登录： [root@ruirui mnt]# telnet 10.88.32.26 23 Trying 10.88.32.26... Connected to 10.88.32.26.
