Perhaps a better idea would be to add loghost as an alternate name to your
host name in /etc/hosts -- and therefore in the yellow pages. Having it in
the name server means everyone knows about it, and they don't need to. You
should also probably have a mailhost entry, depending on your setup.

Our /etc/hosts:

localhost	127.0.0.1
uop		138.9.200.1	loghost mailhost
zeus		138.9.200.2

So the yellow pages can tell you who is the mailhost and loghost, but
nobody else really needs to know.

Also, there is a bug in older syslogs that keep them from working in this
regard. The fix is to simply define LOGHOST near the begining of the file
on your loghost machine. Kinda defeats the purpose. SunOS 4.1 does not
have this bug. SunOS 4.0 does. I don't know where in between it got fixed.
