OK, I got curious since it involves icmp, so it's not done in 
/etc/inetd.conf, and I didn't know how to do it. 
All I can say is RTFM, it's right there in the icpm man page that 
I tried first.

Just put this in /etc/sysctl.conf to turn ping replies off:


Then run

# sysctl -p

But after that you should really go back to /etc/sysctl.conf and get rid of 
it again (hint: it involves running sysctrl again :-).

What the hell,
