Hi;
I am using FreeBSD-5.3 as a terminal server for a few thin client

mediaopt full-duplex

and the outside interface is from DHCP.
The clients are configured similarly 172.16.0.2, 172.16.0.3, etc.
In the /etc/hosts files, I have:
172.16.0.1  tserv
172.16.0.2  gu2
172.16.0.3  gu3
/etc/nsswitch.conf is the default:
group: compat
group_compat: nis
hosts: files dns
networks: files
passwd: compat
passwd_compat: nis
shells: files
I am using kdm and xdmcp to connect. When the client connects I get
a message that says:
DNS spoof attempt or misconfigured resolver.
The main symptom though is that programs are extremely slow to start
up, and menus react very slowly.
I am connected through a hub (not a switch) but I have had this system
set up like this before (using FreeBSD 4.8) and it was much more
responsive.
What am I missing?
I don't know.  You may have already discovered that this error message
comes from kdebase/kdm/backend/xdmcp.c, apparently from a routine
that, not unexpectedly, is attempting to resolve hostnames from a
network address.
I don't read C well enough to even know what might be happening here.
It might be interesting to know if any machines were attempting to use
IPv6.  It appears that ossi removed support for IPv6 from xdm last April,
because, according to the commit log, it was not perfect, particularly on
anything but Solaris.  I don't know if that's out of date now, or not.
Now, FreeBSD 5 generally has IPv6 out of the box, so I wonder ...
but as I said, I'm in way over my head on this one.
Have you tried a kde users list?  Or maybe the freebsd-x11 one?
