No, that message is coming out of the ipod code directly. Looking at
the defs file, the IP/Mask that the kernel prints out look okay, which
means the shared "secret" might not be set right. This is "ipodhash"
in the nodes table.

There are a bunch of sysctl variables in the kernel. They all have the
string ipod in them so try this:

{3} nodeg$ sudo sysctl  -a | grep -i ipod
net.ipv4.icmp_ipod_key = 511cd06aa336d20ab9a79c7bb54a38cc
net.ipv4.icmp_ipod_mask = -1
net.ipv4.icmp_ipod_host = -1688068026
net.ipv4.icmp_ipod_enabled = 1
net.ipv4.icmp_ipod_version = 2

And then check the nodes table for the node to see if the ipod hash
matches.
