More weirdness. At home, the -broadcast option works, with
ACL, as long as I have localhost in the ACL. At school, the
-broadcast option doesn't work, even with no ACL.
From tcpdump, the YP server (orac) sees the request to
18.104.22.168.sunrpc. But ypserv never logs it. However, ypserv
is logging all sorts of requests for other domains than the one
it serves, from other valid domains on our subnet, so I know the
ypserv is noticing other broadcasts.
Does anyone know what in the world could be causing such
weirdness? The client is running 1.3G from Mon Aug 10, the
server is running 1.3F from Jun 29. The subnet has around 200
hosts on it, but that shouldn't affect anything, since the server
is able to see the broadcasts????
