Greetings,

I've got a DECstation 3100 running Ultrix (sematech) connected
to tamu.edu (hence sematech.tamu.edu).  Recently Computing Services
went and changed the network to allow subnetting.  I followed 
instructions on how to change sematech's IP address, and how
to update the /etc/hosts and /etc/rc.local files.  Everything
went fine w.r.t. our campus network.  Sematech knows about 
all the machines on our network, and vice versa, but it (sematech)
doesn't know anything about the outside world.  For example,
I used to be able to ping uunet.uu.net, and now I can't because
"network is unreachable".  The entry in my rc.local file
looks like this:

/etc/ifconfig ln0 `/bin/hostname` broadcast 128.194.3.255 \
				  netmask 255.255.255.0

My /etc/hosts file is up to date.  What am I doing wrong?
Is it something to do with BIND/Hesiod (I'm pretty sure I'm sup-
posed to be a client machine - not a server, not a gateway).
I think that when I ping uunet.uu.net, this should get translated
somehow by my domain server, but it doesn't.  Note that I can
rlogin to a machine elsewhere on tamu.edu, and *it* knows about
uunet.uu.net.

Any suggestions/comments/help is greatly appreciated.

Thanks in advance.  Please email at andrewd@cs.tamu.edu.
