We have a set of backend servers  running  xinetd based proprietary TCP
services. We use ZXTM to round robin requests to the backend servers.
Currently ZXTM provides TCP based monitors that connect to a port and checks
if the service is alive. Since it completes the 3 way handshake, the xinetd
service launches the process when the connect happens.

Is there a way in ZXTM to send a SYN and when SYN-ACK is received, send a
RST?

I believe F5 supports tcp half open monitors that provide the same
functionality. Is there a ZXTM equivalent?

thanks
Ramesh
