How to close connect via net.createConnection?

Question

Node.js

I open a connection via net.createConnection,
how can I force it to close?
var client = net.createConnection({ port: 9801, host:'10.31.200.161' });
client end(); - Does not help

Answer 1

the end method only sends a FIN packet, the connection will be closed when the other side also sends a FIN packet.
to break the connection unilaterally (without sending anything to the other side), there is a destroy method
