To verify connectivity to the mainframe, run this command: telnet <mainframe's IP address>.
要检验到主机的连接，请运行以下命令：telnet <mainframe'sIPaddress>。
If you use Telnet to connect to the server by name rather than IP address, pay special attention to the IP address returned.
如果您使用telnet连接到服务器名称，而非ip地址，要特别注意返回的IP地址。
The example sends a message to the client IP 192.168.9.14, if the client tries to connect using Telnet or SSH.
如果IP为192.168.9.14的客户端试图用telnet或ssh连接，那么该示例会发送消息给它。
Now, further assume that we wish to allow access for SSH and Telnet using the following IP addresses: 192.168.4.10 and all IP address that start with 192.168.6.
现在进一步假设我们允许使用以下IP地址远程登录ssh和telnet：192.168.4.10和所有以192.168.6开头的IP地址。
In the following example, all SSH and Telnet connections coming from the client that has the IP address 192.168.9.24 are allowed access.
在以下示例中，所有来自IP地址为192.168.9.24的ssh和telnet连接都会被允许访问。
In the following example, all SSH and Telnet connections coming from the client that has the IP address 192.168.9.24 are allowed access.
在以下示例中，所有来自IP地址为192.168.9.24的ssh和telnet连接都会被允许访问。
