What is the correct way to restart inetd The correct way to restart inetd is to use the service access command sacadm. # sacadm -k -p inetd <--- kill inetd port monitor # sacadm -s -p inetd <--- start inetd port monitor If you try to kill inetd the CX/UX way by killing the pid, you will notice that you cannot restart inetd. This is because PowerMAX OS (based on SVR4) uses the service access controller (sac) for the inetd service. For more information see sacadm(1), sac(1), or inetd(1).
