ifconfig lo0 question, ultrix32 1.2

[ramey at ti-csl]

We have 2 780's running Ultrix.  One runs version 1.1, the other we
just installed with 1.2.  On the 1.2 host, syslog doesn't work.  The
only difference I could tell between the two systems is that when I do
`/etc/ifconfig lo0', the 1.1 system gives the flags UP,RUNNING but the
1.2 system only says UP.  I recompiled syslog using 1.1 sources and the
perror message was `Network is unreachable'.

Any ideas what is wrong?  The fact that the RUNNING flag is not present
apparently makes lo0 unusable; telnets to localhost apparently go over
the ethernet rather than through the loopback, for example.
