initially i thought my hdd was having problem. so, i changed my hdd. but it still hang 
during boot time and sometimes it also hanged during some execution of program. 
the good news is that it does not hang that frequent after i changed my hdd. 

my netbsd box is running with dhcp, ipf, ipnat and squid. 
my dhcpd is also having problem. it stopped itself with core dumped. and it always is 
showing non-null pointer error while doing dynamic dns update. 

I have 4 network interface cards, 2 public, 2 private. i have configured my netbsd box 
to do ip forwarding. but the ip masquerading does not work. : (
