Can not connect and receive "Incoming packet was garbled on decryption" msg.

I've tried to use WinSCP2 ver. 2.2.3 to connect to remote host. My problem is I can not connect to remote server and recive message: "Incoming packet was garbled on decryption".
When I use "scp" command form linux system to connect to that remote host all files are copied correctly.

Below is debug log from my "scp" linux connection:

Hi all,

i just expected the same problem when connecting
to a sshd2 on a debian woody machine.
"Incoming packet was garbled on decryption"
If i use sftp2 on that debian machine to connect to itself everything works fine.

If i try psftp i get the following error:
Fatal: unable to initialise SFTP: could not connect
Verbose output is:
======

I have no problems to connect to debian machines which are running sshd (not sshd2).
So i would suggest its a problem with sshd2.

If you need further information just tell me.


Thanx in advance,

Please read Putty FAQ on "A.6.18 Since my SSH server was upgraded to OpenSSH 3.1p1/3.4p1, I can no longer connect with PuTTY" (<invalid hyperlink removed by admin>). According to this document, problem is on the server side. Workaround is to use SSH2 with Blowfish encryption. Please, let me know, if it helps.
