The reason these things run from inetd accept new configs ASAP is because each connection runs the program for that server again, causing it to reread all the config files.

Any ideas? The only way I can think of of doing what you're talking about is to rewrite the listen loop to use kevents so you can watch for the configuration file(s) to change as well as for connection attempts. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
