As I learned recently (investigating another issue and reading the rc.subr(8) man page), if you start these with rc scripts, you can set daemon_rtable there, as well as likely setting up the config file or port/ip address options in daemon_flags. Also be sure pexp variable is set to somthing that can differentiate the proceses or the rcctl stop/check stuff will not work. Allan
