Yep, that was me.

interfaces on the same physical network, but the question remains:  "Why is
my Linux box sending ARP replies from both interfaces?" <<

Interesting thought. None of my Linux machines are dual-homed at the moment,

ARP bug in it? <<

Interesting again, but it seems unlikely (to me) that SSH is affecting ARP.

AFAIK, ARP is handled completely in the kernel, and I don't think SSH has
any interaction with that code.

Anyone else here have better knowledge in this area?
