cron emailed me about rdate where it wouldnt have done so before. My crontab
looks like this:

# keep the clock in sync
*/30    *       *       *       *       /usr/sbin/rdate -sna blanc

The mail I got looked like this.

ntpdc -np (running ntpd-4.1.74 from ports, not sure what else you would like
to see) from blanc looks like this:

loki@blanc etc$ ntpdc -np
     remote           local      st poll reach  delay   offset    disp

This is rdate on gris talking to blanc again:

loki@gris rdate$ rdate -np blanc

I've been downloading rather heavily for the past few hours. This is the
only change in my environment since I spoke to you on irc (im tomcarrol or
tomcarro1 or whoever I am today).

If you want to get in contact with me, try irc, otherwise you can email me.
If you want I can arrange an account on gris for you so you can look at the
issue in more depth.

Regards,
David Gwynne
