NB-nokeep

This attribute enables or disables TCP keepalives. It defaults to off. If you set the option it to on, the system does not enable TCP keepalives. If the underlying TCP implementation provides keepalives, NetBIOS TCP sessions normally enable TCP keepalives. TCP keepalives differ from NetBIOS keepalives, which have separate controls.

Usage:

tntransport -M -n tcpip -a NB-nokeep={on|off}
