When logging on to a server using the SFTP protocol and downloading a file, the following exception is thrown and the download is aborted.

I tried several different servers with the same result. Uploading works fine, and downloading from ordinary FTP servers works without problem.

As a workaround use SCP transfers (Change in Preferences > SFTP). Do you know what SSH software is running on the server?

On of the servers is a debian machine. Running sshd -v gives the following result, if it helps.

OpenSSH_3.8.1p1 Debian-8.sarge.6, OpenSSL 0.9.7e 25 Oct 2004

Would it be possible to get a temporary account on this server?

Hi, I'm also having this issue on all the servers I typically connect to (Redhat and CentOS). Some of them are using this:

OpenSSH_4.2p1, OpenSSL 0.9.7f 22 Mar 2005

And others are using this:

sshd version OpenSSH_3.6.1p2

And one is using this:

OpenSSH_4.3p2, OpenSSL 0.9.8b 04 May 2006

The problem happens when trying to download any file.

Couldn't try out the SCP workaround because when I try to open the preferences, the app crashes. :(

(BTW, I know some web hosts who allow SFTP and SSH but specifically disallow SCP connections)

=#### Tuesday, August 14, 2007 13:26:10 US/Eastern=
214917 [Background] ERROR ch.cyberduck.core.sftp.SFTPPath - SSH channel is closed. (Closing all channels)

I was just trying the new beta. Now that I can set the SCP preference, that works. When I set it back to SFTP, I get the invalid len argument on download and the above is what I see in the console.

So, I removed my preferences and things were working again with SFTP. I tried to compare the good and bad prefs but there's a lot of differences. I did verify that the problem isn't the enterkey.rename pref which I had changed.

If you would like a copy of the good and bad preference files, please email me at pburney@concord.org

So, this issue is no longer valid for me, but I'm not the original poster.

Sincerely,

Paul Burney
