Using a standard recieve string NTttcp.exe -r -v -p 1025 -m 1,3, It fails and this is the resulting output :

4/13/2022 11:33:22 StartSenderReceiver start thread 0 port 1025 4/13/2022 11:33:22 SetupNet port 1025 4/13/2022 11:33:22 bound to port 1025 4/13/2022 11:33:22 ERROR: SetupNet failed: error in connect/bind function, GetLastError: 10049 - The requested address is not valid in its context. 4/13/2022 11:33:22 ERROR: StartSenderReceiver in thread: 0 failed: error in SetupNet function 4/13/2022 11:33:22 ERROR: StartSenderReceiver in thread: 0 failed: closesocket, GetLastError: 10038 - An operation was attempted on something that is not a socket.

It's windows server 2018 running powershell in administrator mode. There is no other error information, just the above. Please advise.

In this paste, it looks like you didn't specify the IP address of the interface receiving the traffic. Should be -m 1,3,192.168.1.1 or whatever the IP of your target interface is.

In my case I have same error but IP is specified: 11/11/2023 10:27:16 proc_speed: 3600 MHz 11/11/2023 10:27:16 SetupThreads 11/11/2023 10:27:16 Threads: 1 Processor: 3 Host: 192.168.1.130 11/11/2023 10:27:16 created thread 0 port 5001 11/11/2023 10:27:16 StartSenderReceiver start thread 0 port 5001 11/11/2023 10:27:16 SetupNet port 5001 11/11/2023 10:27:16 bound to port 5001 11/11/2023 10:27:16 ERROR: SetupNet failed: error in connect/bind function, GetLastError: 10049 - The requested address is not valid in its context. 11/11/2023 10:27:16 ERROR: StartSenderReceiver in thread: 0 failed: error in SetupNet function 11/11/2023 10:27:16 ERROR: StartSenderReceiver in thread: 0 failed: closesocket, GetLastError: 10038 - An operation was attempted on something that is not a socket. 11/11/2023 10:27:16 StartSenderReceiver done thread 0 port 5001

Command was: .\NTttcp.exe -r -v -m 1,*,192.168.1.130 -rb 100kb What might be the problem? In packet capture I can see packets coming in from sender machine but this receiver does not send SYN ACK.
