IRC, unknown channel, unknown date.
<grey_gandalf> I did a sudo date...
<grey_gandalf> and the machine hangs
This was very likely as misdiagnosis:
IRC, freenode, #hurd, 2011-03-25
<tschwinge> antrik: I suspect it'S some timing stuff in pfinet that perhaps
uses absolute time, and somehow wildely gets confused?
<antrik> tschwinge: BTW, pfinet doesn't actually die I think -- it just
drops open connections...
<antrik> perhaps it thinks they timed out
<tschwinge> antrik: Isn't the translator restarted instead?
<antrik> don't think so
<antrik> when pfinet actually dies, I also loose the NFS mounts, which
doesn't happen in this case
<antrik> hehe "... and the machine hangs"
<antrik> he didn't bother to check that the machine is perfectly fine, only
the SSH connection got dropped
<tschwinge> Ah, I see. So it'S perhaps indeed simply closes TCP
connections that have been without data for ``too long''?
<antrik> yeah, that's my guess
<antrik> my clock is speeding, so ntpdate sets it in the past
<antrik> perhaps there is some math that concludes the connection have been
inactive for -200 seconds, which (unsigned) is more than any timeout :-)
<tschwinge> (The other way round, you might likely get some integer
wrap-around, and thus the same result.)
<tschwinge> Yes.
