yes. my ancient configure script does that (it only sets up realservers and not failover directors, so no-one uses it anymore). AFAIconcerned, this is the only way to do it, since you don't have to get your service to listen on the RIP as well. You ssh from the director to the RIP and run a test on the realserver for the service of interest. I use multiscan (see sourceforge for this general purpose service tester - it's a bit old now, but services haven't changed). director:# ssh $realserver_name '/usr/local/bin/multiscan -t $vip' multiscan returns the ports open and you can grep for your service. This isn't as stringent a test as requiring the service to return a valid string from a query, but it was good enough for me. You could substitute mon or your own test for the service. > 2.
