Hello,
I restaged my machine with OS X 10.2.6 and plugged my computer into the university network. The next day I get complaints that my computer is "aggressively" scanning it neighbors. I am not doing this, and I doubt that my computer has been broken into in a matter of hours. Is there some scanning on by default, like for rendezvous? How can I turn it off???

Please help

Jeff

Maybe its appletalk? Try turning it off in network system prefs... although that may only be for hosting, not sure.

Assuming your machine has not been broken into or otherwise owned, yes, it's probably Rendezvous. And there's nothing "aggressive" about it, though network admins on power trips tend to be a little melodramatic.

If they would like more information about Rendezvous, an implementation of the IETF Zeroconf standard, they can visit:

http://www.zeroconf.org/
http://www.multicastdns.org/

To verify that it really is Rendezvous that they're complaining about, you can try:

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

You should see:

Stopping Apple Multicast DNS Responder

If this stops the so-called "aggressive" scans, then it was Rendezvous.

To restart Rendevous, you can issue the command:

sudo /System/Library/StartupItems/mDNSResponder/mDNSResponder start

or reboot.

If that doesn't stop it, it's something else. You may also inform them that Rendezvous (Zeroconf) is going to be becoming a lot more popular on a lot of network devices. HP printers, Lexmark printers, network appliances, drivers for Zeroconf-enabled peripherals, etc., and much more, so they'd better get used to it.

To turn off Rendezvous you can also just open up the application "Directory Access" [/Applications/Utilities/"] and simply uncheck Rendezvous or AppleTalk or whatever network service you want to turn off.

They're probably upset there's a Mac on the network.

Argh, arrogant, computer-illerate sysadmins are the most annoying people in the universe.

I remember the one that ran the network back when I was in high school - she wouldn't let certain science teachers onto the school network because they had Macs, and she didn't like them. She kept claiming that the Mac was not compatible with the network because Macs can't connect to a DHCP server.

One of my friends had roughly the same experience. She was told she couldn't use a Mac because there wasn't a "Mac network port" near her desk.

I hate retarded PC fanboys.

This is a whole other subject, but I think these are the people (that have a lot of influence with their families, neighborhood, etc.) that stunt Apple's growth more than anything else.

It's almost ridiculous how much I hate them.

One of my coworkers had a problem like this - the sysadmin complained that his machine was putting out packets once a second. We ran ethereal on his machine, and it was true. He had both the ethernet and Airport interfaces turned on with no Airport base station in range, and the Mac was putting out requests to the 10.0.x.x network over the ethernet port on port 192. Port 192 is used by Airport to determine the status of a PPoE connection on the base station.

The workaround was to turn off the Airport network in the network system preference when hooked up to the ethernet.

They will be the first up against the wall when the revolution comes.

Our network admin wouldn't know if I hosted a porn and worz FTP server on my work computer!

Some of our work printers aren't secure (no password required and Rendezvous turned on)... and have been showing up in Print Center... I told the network admins and I'm now treated like a terrorist.

I'll never forget when I was told in a school one-time that if I attempted to use the wireless access points they had installed (non-Apple)...that I would fry my Airport card and cause the whole entire network to go down....

Rrrrrriiiiggghhhttt....

That happens all the time... but it has nothing to do with your Airport card :-)

My campus has an M$ only VPN piece of software for wireless access and is pissing me off...
