Security Incidents: Re: possible DNS problem ??

Re: possible DNS problem ??

I'm unsure of how you relate the 'clear' program to a DNS bug. The clear
program "clears" the terminal. Perhaps the problem resides elsewhere? Note
that the core was dropped due to a Signal 11. Try upgrading (or compiling
from source) the clear program and see if it keeps happening.

If you get Signal 11's often you may want to check your hardware for problems.

>From the man page:
-- Snip --
clear(1) clear(1)

NAME
       clear - clear the terminal screen
