I've got a Jaguar box on my LAN configured with a static IP address. It seems as though it is broadcasting a different address across the network. Here is the ping response I get:

Reply from 239.255.255.253: bytes=32 time<10ms TTL=64

The 239 number above is indeed coming from my Jag box (another network admin sourced it to my Jag box, and if I restart it, it goes away until it boots fully, then it returns), which is NOT configured with that IP address. It has a static IP from a different IP block entirely.

I've turned off all services (ftp, smb, afp, etc.) and it is still doing it.

Anyone know what it is?

Well, I've pretty much narrowed it down to Rendezvous, which uses IP multicasting. So now that I know what it is, can Rendezvous be turned off? There is no apparent option for this in the GUI, but I would imagine it would be able to be disabled via the command line.

Anyone know how to turn off Rendezvous?

Shut off Rendezvous? Well,

sudo /System/Library/StartupItems/mDNSResponder/mDNSResponder stop

might do the trick.

Good luck.

Ah, thank you very much. However, will killing the mDNSResponder process persist beyond a restart? Can this be configured via inetd.conf to NOT initialize at startup at all?

TIA,

Just comment out the line
/usr/sbin/mDNSResponder

in the file
/System/Library/StartupItems/mDNSResponder/mDNSResponder

Or you could just move the whole directory somewhere else. But that's kinda kludgy...hmm...I looked in /etc/hostconfig, there is no config for Rendezvous and no sign of it in the actual startup script. I wonder if you could add one? {drag this to a clipping, 10 minutes and several restarts go by, drag this back} Sure can. Modify the mDNSResponder startup script like so:

<snip>
StartService ()
{
if [ "${RENDEZVOUS:=-NO-}" = "-YES-" ]; then

##
# Startup the Multi-cast DNS Responder if it is available on the system
##
if [ -f /usr/sbin/mDNSResponder ]; then
if pid=$(GetPID mDNSResponder); then
return 0
else
ConsoleMessage "Starting Apple Multicast DNS Responder"
/usr/sbin/mDNSResponder
fi
fi
fi
}
<snip>

Just add the lines in red. Then add the line

RENDEZVOUS=-NO- in /etc/hostconfig

Now you can just change /etc/hostconfig to turn the service off and on. Impress your friends!
