It's the only one on which the problem is evident.  The others are
not exercised thoroughly, and I might have overlooked the problem
on them anyway.

I haven't heard of wireshark until now, but will look into it.

It looks roughly like this: Cisco 678, with an old Webramp
something running Sonicwall SOHO firmware, both in a nest of power
cables, then CAT5 cable from there running over doors, across
floors, and down a handrail, around the corner, over some doors
and through a couple closets to a desk where there's some no-name
switch buried in a pile of network cables, power cables, and
various other gear.  Not pretty.

But these are TCP connections.  Isn't any junk on the wire
supposed to be cleaned up at the transport layer?

Not if it involves a trip to the storage room to dig through "the
archives" to find a NIC, it isn't.  I haven't used a standalone
one since motherboards started coming with inbuilt NICs.
