-rw-r--r-- 1 root root 59040 10月 17 13:24 telnet-0.17-47.el6.x86_64.rpm

-rw-r--r-- 1 root root 37360 10月 17 13:24 telnet-server-0.17-47.el6.x86_64.rpm

-rw-r--r-- 1 root root 123624 10月 17 13:24 xinetd-2.3.14-34.el6.x86_64.rpm

##2. 安装telnet相关

[root@ywb rpm]# rpm -ivh xinetd-2.3.14-34.el6.x86_64.rpm

[root@ywb rpm]# rpm -ivh telnet-0.17-47.el6.x86_64.rpm

[root@ywb rpm]# rpm -ivh telnet-server-0.17-47.el6.x86_64.rpm

##3. 检查安装结果

[root@ywb rpm]# rpm -qa | grep xinetd

xinetd-2.3.14-34.el6.x86_64

[root@ywb rpm]# rpm -qa | grep telnet

telnet-0.17-47.el6.x86_64

telnet-server-0.17-47.el6.x86_64

##4. telnet服务之后,默认是不开启服务,修改文件/etc/xinetd.d/telnet来开启服务

[root@ywb rpm]# vi /etc/xinetd.d/telnet

[root@ywb rpm]# cat /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= no #这里把yes修改成no

}

##5. 启动telnet和依赖的xinetd服务

[root@ywb rpm]# systemctl start xinetd

##6. 查看启动状态

[root@ywb rpm]# systemctl status xinetd

[root@ywb rpm]# which telnet

/usr/bin/telnet

#备注：个人感觉仅仅安装一个telnet-0.17-47.el6.x86_64.rpm包即可

[root@ywb rpm]# rpm -ivh telnet-0.17-47.el6.x86_64.rpm

[root@ywb rpm]# which telnet

/usr/bin/telnet
