Kernel panic with kldload
I've been trying to make a little BSD sockets kernel loadable module thing.
(Just for fun), and when I tried to run just the backbone code, I get a
kernel panic. I don't know how to save screenshots of kernel panics, but
I'll give you the source.

when compiled and ran, makes my 4.7-release box quit EVERY SINGLE PROGRAM
(including boot-time daemons), and go into a fix-it shell.
My question is this: why does this happen? I can't seem to figure it out.
I've worked with many other people about this, and they don't seem to know.
(When you exit the fix-it shell, the computer finishes booting, it's like
going into single-user mode upon boot)
Run this code and see what happens (nothing bad, just wierd).

Samba and Win2k
I just got a samba server running on a FreeBSD box. Whenever trying to change the perm bits on a file from Win2k (Read-Only, Hidden, Archive), then click on the desktop, "Explorer.exe" crashes.

DNS and DHCPD
I would like to configure my dhcpd server (isc-dhcpd3 from ports). I would also like to have the "options domainnameservers" (or somewhat similar) to be dynamic, as my fBSD box is my own router. (I run a local network). The WAN side is DHCP'd, so my IP and DNS servers are set differently each time. I was wondering how to set the domainname servers option in my dhcpd.conf dynamically. Like, it would get edited each time upon bootup, and before dhcpd even loads. I don't know how to even start approaching this problem, except for asking you guys.
