Re: 19990823: LDM Down?

Bob et al,

Apparently, there was a change so that udp protocol doesn't show up
anymore for the LDM.  I was unaware of this change. ie

% rpcinfo -p

    300029    5   tcp    388  ldmd
    300029    4   tcp    388  ldmd

If you want to continue with your test, change udp to tcp.

Robb...
