scp problems?

[Geoffrey Alan Washburn]

	Hi.  So I have been having problems using scp to copy
  files between two of my machines, both of which are running OpenSSH
  2.30p1 (though I've had the same problem with previous versions).
  It is basically as simple as the file not being transferred after
  authentication occurs.  I can however use scp to copy files back and
  forth from another machine using a SSH Communications version 1.2.27
  daemon and client.  Additionally, ssh between the two hosts itself works
  perfectly.  Here is a log of what happens on the sender:

$ scp -v -v -v foo.bar xxxxxxxx:
Executing: program /usr/local/openssh/bin/ssh host xxxxxxxx, user
(unspecified), command scp -v -t .
gw2 at xxxxxxxx's password:
stty: standard input: Invalid argument
$

  And here is the receiver:

  Both the sender and receiver were compiled with the following
  configuration:

    --with-kerberos4
    --with-afs=/usr/local/lib/afs
    --with-default-path=/bin:/usr/bin:/usr/local/bin

  If you have any other questions let me know.  This has been bugging me
  for a long time now...
