Yup, diald is in full force here.  

Let me try some somewhat off-topic questions here: I really think the ISP
is clueless and not communicating the presence of our network to its
upstream provider.  Could a bunch of you developers please try the
following three traceroute commands and tell me what you get?

% traceroute 204.186.27.145
% traceroute 204.186.230.1
% traceroute 204.186.230.2

.27.145 is the modem and the connection to the Internet via the ISP.
.230.1 is the ethernet card in the Linux box, on the local area network.
.230.2 is the NT server which will be our second DNS server, etc.

I seem to get caught in a routing loop at fngw-T3-prolog.NEREP.NET when I
try the second and third command, and it looks to me like that router is
misconfigured.  The ISP claims that traceroute (and ping) won't work until
DNS is ready. 

I also can't seem to get out of the intranet via the Linux diald machine.
I'm testing stuff using tracert under WinNT, and getting *'s.  Here's the
output of route (I've tried cleaning it up manually, but it still doesn't
route):

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
cs10.mil.ptd.ne *               255.255.255.255 UH    0      0        1 ppp0
cs10.mil.ptd.ne *               255.255.255.255 UH    1      0        0 sl0
204.186.230.0   *               255.255.255.0   U     0      0       24 eth0
127.0.0.0       *               255.0.0.0       U     0      0       70 lo
default         cs10.mil.ptd.ne 0.0.0.0         UG    1      0        3 ppp0

I have created some accounts for generic testing.  If any of are brave
enough to take a snoop on the actual machine, let me know and I'll "let
you in."

Thanks so much for your help.  I think I'm going to be bald at a young
age...
