A Cautionary Tale for Silly People ----------------------------------
For the past year now, I've had "ping" problems.
It pauses when it runs, and always returns warnings like so:
"Warning: time of day goes back, taking countermeasures"
I looked _everywhere_ on the net trying to find the problem.
I upgraded the kernel many times. I upgraded glibc a few times. I upgraded iputils a few times as well.
Nothing helped.
The clock was sync'd with an atomic clock every night.
Still, I kept getting the problem.
Then while moving log files around today, I noticed that the clock 'second' didn't move. Weird.
So I ran this: while : do date "+%H:%M:%S" done
I got interesting results:
17:05:24 17:05:24 17:05:24 17:05:33 17:05:33 17:05:25 17:05:25 17:05:33 17:05:25 17:05:25
Nice huh!
Why?
I looked inside the box and found a Pentium II 400, and a Pentium II 450.
Oddly enough they run together as a 266.
