First, the Tools / materials
- Telnet server and Telnet client
- Two PC machine, the virtual machine can also be, (here with a virtual machine and virtual machine system win7 XP system)
- Network mode two virtual machines are "bridge mode"
- Closed two virtual machines behind a firewall into the system, or it may not ping each other
Second, the method / step
1, configure the telnet service on the PC
1.1 disposed on win7 system
win7 system IP address (192.168.1.6/24) information, and the communication system of XP
1.1.1, open the telnet program
Open the "Control Panel" - "Programs" (see the top right corner of the way to 'category') - "Programs and Features" - "Turn Windows features", the "Telnet Server" and "Telnet Client "hook

1.2.3、检验telnet服务是否安装成功
打开命令窗口cmd，输入“telnet -help”，没有提示“telnet不是内部或外部命令”则表示已安装成功
2、使用telnet远程访问主机（此处用XP系统访问win7系统）
若使用Telnet协议远程访问主机，其访问主机和被访问主机都必须安装相应Telnet服务，被访问主机需将用户组中某个用户添加为隶属于TelnetClinets组，其访问主机输入用户名和密码才可访问被访问主机。
2.1、在被访问主机上添加某个用户隶属于TelnetClients组
右键“计算机”——“管理”——“系统工具”——“本地用户和组”——“用户”——“属性”——“隶属于”——“添加”
在“输入对象名称来选择”输入“TelnetClients”——“确定”
2.2、用telnet [被访问主机ip地址] [端口号]命令访问远程主机
打开命令窗口cmd，输入命令 telnet 192.168.1.6
输入y，回车
输入被访问主机用户名和密码
已进入win7系统的命令窗口，telnet远程访问成功
