Linux 环境下未安装telnet,会出现以下错误:

[[email protected] ~]# telnet 129.223.248.159
bash: telnet: command not found...


解决方案需要安装telnet服务,此处采用yum install,可以参考 RedHat 7 使用Centos7 的yum源


yum list telnet* 列出安装包

yum install telnet-server 安装server

yum install telnet.* 安装客户端

bash: telnet: command not found...
