OS X like Stealth Mode - iptables ??
I am using RHEL4. Is there a way to setup iptables in similar fashion with "stealth mode" and block port scans etc.?

Wow, "Stealth Mode". Nice marketing buzzword.
If you do not want a port reachable, you should close the application that opens it.
And just not responding to ping requests doesn't make you invisible by any means.
That said, you can of course block all ICMP requests.
Linux Iptables allow or block ICMP ping request

Would be great if there was a simple BASH script (to be run as root via sudo perhaps) to turn this off and on, on-the-fly.A man learns from his experience. A smart man learns from the experience of others, while a smarter man experiences life after knowing other's experiences.
