Subject:   why not use mDNSResponder instead of mdNSProxyResponder?

mDNSResponder has a -d flag to autodaemonize, and can also read in a configuration file of hosts/services to advertise as opposed to the one host/service per instance problem mDNSProxyResponder has.


or is there something funky with your setup that requires it? (ie nocat being a captive portal)

    mDNSResponder won't let you advertise arbitrary IP addresses. It will only advertise local services, and in my case, I'm running the advertiser on a separate box from my web server.

    But if you are advertising services on the same machine that they are served from, mDNSResponderPosix would do the trick nicely.

      I'm trying to write a redhat init script to turn the responder on and off. The daemonized version, how can I look up the PID to kill it (and therefore allow the script to respond to a "service rendezvous stop" command)?

        The quickest way is to just run killall mDNSProxyResponder to kill the job by name. You could also do something like kill `ps ax|grep mDNSProxyResponder|grep -v grep|awk '{print $1}'` (although the first one is much simpler...)

          The proper way to write an init script is to use the init.d functions in /etc/rc.d/init.d/functions by calling them at the start of the script. See other init scripts for an example.

          These functions handle all pid details for you, and more. Find more info on them at:
