Seeing same/similar issue. While doing SSH or SCP to a Hardy x64 install
(Linux hardy 2.6.24-21-server #1 SMP Mon Aug 25 17:28:54 UTC 2008 x86_64
GNU/Linux)
What I am seeing via a TCP dump on the server is that it is sending
packets up to 2954 bytes. The MTU on the interface is standard and set
at 1500 bytes.
