Mac OS 10.4 Tiger Stealth Mode

May 2, 2005 amida168 Mac OS 2

The new stealth mode in Tiger is just this ipfw command

ipfw -q add 20000 deny icmp from any to me in icmptypes 8

  • Does this essentially make your Mac invisible by not responding to ANYTHING you didn’t originate?

    From the System Preferences, Apple states “Ensure that any uninvited traffic received no response – not even an acknowledgement that your computer exists.”. However, it seems to me that the stealth mode only denies type 8 of ICMP traffic(ping).
