sshd problem: recursive scp seems to fail acting as server OpenSSH_4.3p1, OpenSSL 0.9.8a


I'm seeing an odd behavior with the latest openssh package.

When I scp -r files from a cygwin host running sshd, the directory will copy
over, but none of the files within.

The cygwin ssh client doesn't seem to have that problem that I've seen.

Here's the illustration with some verbosity:

1) cygwin server with files bar and foo in var:
pwohlers@cygwinhost ~/var
$ ll
total 8
-rw-r--r-- 1 Domain Users 1221 Feb 10 01:57 bar
-rw-r--r-- 1 Domain Users 1221 Feb 10 01:57 foo

2)Nothing on linuxhost:
pwohlers@linuxhost:~
$ ll | grep var
<returns nothing>

3) recursively scp var from remote cygwin server to local linux client:
pwohlers@linuxhost:~
$ scp -r cygwinhost:var .
pwohlers@cygwinhost's password:

4) looks like it made it:
pwohlers@linuxhost:~
$ ll | grep var
dr-xr-x---    2 pwohlers pwohlers     4096 Feb 10 01:58 var

5) But where are the files?:
pwohlers@linuxhost:~
$ ll var
total 12
dr-xr-x---    2 pwohlers pwohlers     4096 Feb 10 01:58 .
drwxr-xr-x   55 pwohlers pwohlers     8192 Feb 10 01:58 ..


6) deleted linuxhost:var and try again with -vv:

pwohlers@linuxhost:~
$ scp -rvv cygwinhost:var .
Executing: program /usr/bin/ssh host cygwinhost, user (unspecified), command
scp -v -r -f var

7) And again, directory gets transferred, but not files:
pwohlers@linuxhost:~
$ ll var
total 12
dr-xr-x---    2 pwohlers pwohlers     4096 Feb 10 01:58 .
drwxr-xr-x   55 pwohlers pwohlers     8192 Feb 10 01:58 ..

Has anyone else seen this or is pilot error to blame?

Any input appreciated.

(btw, Cygwin is fabulous! Thanks!)
