And it should be available as early as possible during boot, so I think
its place is in init(8).

what we need is an e
When things arrive out of sequence, that usually is of special interest to
network operator people. Not sure the sequence field can easily be
overloaded to increase “validity”.
I’m not great at math, with a 16 bit random value, wouldn’t we start
running into ID collisions around 256 concurrent pi

A whole bunch of protocols got holed because of that attitude.
We never claimed that OpenBSD ping conforms to the
'High Availability ICMP ECHO' RFC.

Hi all!
While working on home job for students, I've come across two
questionable thingies in ping.c:
1. It sends process PID (well, last 16 bits) to the network.
Maybe I'm a bit paranoid, but this looks like bad idea for me.
I understand that this worked good when PIDs were 16-bit limited,
