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.
