I was going through some old mail archives and I found this:
Date: Tue, 29 Apr 1997 01:02:01 -0500 Subject: Auto Reset of ipfwadm stats Tue Apr 29 01:02:01 CDT 1997 Stats for yesterday: IP accounting rules pkts bytes dir prot source destination ports 144 28693 i/o all ppp01.hoopeston.k12.il.us anywhere n/a 7336 2332K i/o all ppp02.hoopeston.k12.il.us anywhere n/a 0 0 i/o all ppp03.hoopeston.k12.il.us anywhere n/a 0 0 i/o all ppp04.hoopeston.k12.il.us anywhere n/a
That’s just the earliest mail I can find, it was running before April. Hard to believe we’ve had dialup running in Hoopeston for more than 10 years.
