Yes yes ! Normally the connect(2) should be followed by a send(2). It is impossible to strace and use survfutex at the same time on your process because both of them use the ptrace(2) and a process cannot be ptraced twice at the same time (the ATTACH will not work). But, you can use the tcpdump command to trace the packets and see if the three-phase connect (SYN sent, SYN-ACK received, ACK sent) are seen on the network. If so and your connect does not success (or waits), yes your connect is in strange state.
