Is there a way to change the delay?

Hello,
No, getTcpKeepAlive will only tell you if SO_KEEPALIVE is enabled. It's
setTcpKeepAlive you want. If it's enabled, once the keepalive times out on a
half-open scenario, the connectionLost method will be triggered. You can
read the API docs here:
http://twistedmatrix.com/documents/8.2.0/api
I have to poll at the twisted server "getTcpKeepAlive" for the state of the
keep alive.
Thanks,
Garyc

Hello Garyc,
This is not twisted's fault. Pulling a network plug doesn't tell the server
that the client went away immediately since the connection wasn't closed
properly. Pulling the plug produces TCP half-open scenario when one thinks
that the connection is still up. This can be remedied by
poll
