问题描述
问题陈述:
终端上的TCP over IP/PPP/Dialup连接失败以太网电缆已分离
Test1:终端用户应用程序配置为在PPP over上使用TCP/IP拨号.以太网电缆已拔出.终端成功建立调制解调器
和PPP连接，但在TCP连接之前会立即断开连接
尝试.
Test2:以太网电缆连接到集线器.终端成功建立
调制解调器，到远程主机的PPP连接和TCP连接(通过
PPP/拨号).
C ++代码
我们如何区分PPP的DNS请求和以太网的DNS请求.现在，此刻，使用DNS的PPP尝试通过以太网工作，这当然是不正确的行为.
Problem statement:
TCP over IP/PPP/Dialup connection failed on terminal, when
Ethernet cable detached
Test1: terminal user application configured to use TCP/IP over PPP over
Dialup. Ethernet cable is detached. Terminal successfully establish modem
and PPP connections, but immediately disconnects before TCP connection
attempt.
Test2: Ethernet cable attached to Hub. Terminal successfully establishes
modem, PPP connections and TCP connection to remote host (over
PPP/dialup).
C++ Code
how we can separate DNS requests for PPP and DNS requests for Ethernet. Now, at this moment, PPP using DNS, which tries to work through Ethernet and this, of course, is incorrect behavior.
any body pls help on this.
