Since there are neither examples nor a manpage for icmp,
I thought I'd share how I set it up here.

In /sys/src/9/magnum/[magnum magnumcpu], I added an entry for icmp to
the device list as follows:
       icmp    Q

In that same directory, I used "mk", and then "mk 'CONF=magnumcpu'" to
build the 9magnum and 9magnumcpu kernels, which I copied to my tftp area.

In /rc/bin/cpurc, I added (in the case statement for my cpuserver):
       bind -a '#Q' /dev               # icmp device
       aux/icmp                        # icmp listener

and changed the last line to read:
echo -n 'add tcp il udp icmp' > /net/cs

and I added this to /lib/namespace:
bind -a #Q /net
