CentOS 安装并开启Telnet服务
1查看有没有安装telnet服务
rpm –qa|grep telnet 没有则找安装包进行安装。如果有安装光盘，在安装光盘中找到相应的安装包进行安装。这里直接通过网络安装 2、通过yum install安装Telnet程序 [root@bogon xinetd.d]# yum list telnet-server Loading "installonlyn" plugin Setting up repositories Reading repository metadata in from local files Available Packages telnet-server.i386 1:0.17-39.el5 base [root@bogon xinetd.d]# yum install telnet-server Loading "installonlyn" plugin Setting up Install Process Setting up repositories Reading repository metadata in from local files Parsing package install arguments Resolving Dependencies --> Populating transaction set with selected packages.

3、修改配置文件more /etc/xinetd.d/telnet
[root@bogon xinetd.d]# more 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 } 将disable项由yes改成no。 4、重启服务生效 /etc/init.d/xinetd restart
或者 service xinetd restart
