I never said that disabling PMTUD will get rid of the ping of death,
what I said was that if your system is susceptible to a ping of death
you may be tempted to filter ICMP but if you do that then you need to
disable PMTUD because PMTUD + ICMP filtering = breakage.

After making the jump to academia I often feel a bit long in the tooth
between all these students. But considering that (apparently) some
people have been posting flames on NANOG for 30 years makes me feel
young in comparison. :-)
