On one machine, develop a UDP port 10000 monitoring, TCP listening port 10001 small programs,

Each process is started for the first time, click to start listening to, and will wait for a long time, but the closing process, quick start the second time, to monitor success directly, if the second start time is long, will card,

Under Linux is good, have the situation under Windows, but not every machine are suspected to be connected and firewall or other environment, met someone didn't?

CodePudding user response:

Please to find a problem in the program itself, the firewall will not tube you program in which port to monitor, it just stop or release the request of the access port,

CodePudding user response:

Found in network debugging assistants as well

Netstat ano | find "1000"
Netstat ano | find "1001"
Look at the port before have already in use;
In a Windows computer see if the same situation, if any, is the program problem, if not, is the system problem,

Why to find! Uninstall winpcap, this version of the pcap has a problem
