Hi all,

Two days before RELEASE, I have a nice announcement ...

Newest CURRENT ... Easy to reproduce:

Get http://people.freebsd.org/~mbr/ports/drac.tgz

Install the port.

Add

"drac            33333/tcp"

to /etc/services

Add

"drac    stream  tcp     nowait  root    /usr/local/sbin/rpc.dracd rpc.dracd"

to /etc/inetd.conf

Restart inetd.

telnet localhost 33333

BooooooooooooooooM
