Hi all,
So I have an SSH problem where pushing data over an SSH connation gets
me less than 9600 baud and numerous halts and timeouts. Pulling from the
same host just rips along as you'd expect.

Nothing obvious seen using "ssh -v". Nothing relevant leaps out at me in
To me this suggests the issue is deeper down in the transport, network,
data link of physical layer. Viz, I can't think of anything in OpenSSH
that could be mis-configured to give asymmetric symptoms.
Does this seem like a reasonable hypothesis?
