linux如何开启telnet服务？很多朋友对于这个问题不知道该如何解决；今天小编将为大家带来linux开启telnet服务的方法，有需要的朋友一起去看看吧!

方法：

1. 切换至root用户；

linux,telnet

2. 如果Linux没有安装telnet服务需要先安装，安装过开通即可

3. 检测telnet的rpm包是否安装

[root@localhost ~]# rpm -qa telnet

telnet-0.17-48.el6.x86_64

[root@localhost ~]# 

linux,telnet

4. 安装telnet安装包：

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

warning: xinetd-2.3.14-34.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

Preparing...                ########################################### [100%]       

package xinetd-2:2.3.14-39.el6_4.x86_64 (which is newer than xinetd-2:2.3.14-34.el6.x86_64) is already installed

file /usr/sbin/xinetd from install of xinetd-2:2.3.14-34.el6.x86_64 conflicts with file from package xinetd-2:2.3.14-39.el6_4.x86_64

[root@localhost ~]#

5. 修改telnet服务配置文件

vi /etc/xinetd.d/telnet 

service telnet

{

disable = yes

flags = REUSE

socket_type = stream

wait = no

user = root

server = /usr/sbin/in.telnetd

log_on_failure += USERID

}

将disable=yes改为disable=no

注意：安装telnet-server服务后，系统才会有/usr/sbin/in.telnetd文件

linux,telnet

6.重启telnet服务

[root@localhost root]#service xinetd restart

linux,telnet

7. 测试是否可以，若果不行，检查防火墙是否关闭

[root@localhost ~]# telnet 127.0.0.1

Trying 127.0.0.1...

Connected to 127.0.0.1.
