I am trying to build following simple scheme:
Signal source --> TCP Sink (server mode) <---- TCP Source (client mode)
–> GUI Scope Sink
It’s strange but this simple scheme isn’t working.
sockstat shows me:
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN
igor python2.7 56206 11 tcp4 10.21.32.6:21950 10.21.32.6:12000
Looks like communication between tcp sink and tcp source blocks has been
established, but tcpdump doesn’t show any packets
I decided to check first part of my scheme (Signal source + TCP Sink),
and connected using netcat utility to the tcp sink port. All looks OK,
the values come as expected.
Can anybody explain, why this simple scheme doesn’t work?
