    Grr, rebooted the box before I've checked. Anyway, after a reboot
    I pinged it so that the entry appears, and after 6 hours it's still
    there:

    $ uptime
    23:08 up 6:35, 6 users, load averages: 0,00 0,01 0,00
    $ arp -n 10.71.1.80
    ? (10.71.1.80) at 00:50:fc:79:da:85 on rl0 permanent [ethernet]

    And no, I don't normally have this entry. (All 6 users is me.)

    Cheers,
