DoS attack against TCP services


it was launched a DoS attack against my server. The attacker opened ssh connections from different servers until all sockets are use.

I have stopped the ssh service and terminates all processes. Unfortunately, all TCP connections are now in the TIME_WAIT state.

bash-4.3 # netstat -a -n | grep TIME_WAIT | wc -l

Is there a way to remove it without rebooting the server?

system: netbsd-7.0_BETA

Thank you very much for your efforts
