Sorry if I misunderstood what you were saying. I thought you said that they couldn't have their cake and eat it too, as in protect against Ping of death, AND do PMTUD. As for those flames, well, that was a long time ago, in a valley not too far from here ;-). Can we have the 'net before the endless September back?

I was responding to his post that blocking or disabling PMTUD was the way to avoid the ping of death, which is False, nothing more, nothing less.
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.
As far as who Iljitsch is, everyone misspeaks from time to time. Even those of us who have been at this for nearly 3 decades.
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. :-)
