It's been years since I used Solaris, so I cannot give you the
most modern of answers. The traditional answer would be to use
Weitse's "tcp wrappers" if the idea is to be selective about who
you will accept. If you want to turn off the service to clients
entirely during those time ranges, you could have a cron tab entry
stopped the service or which commented it in/out of inetd.conf
