Transfers larger than 2**31 (2147483648) bytes fail

2565d84 created the issue

When attempting to download more than 2147483648 bytes (Around 2 GB) Cyberduck gives the following error:

SSH Error:
A badly formatted packet or other SFTP protocol incompatibility was detected.

I believe that using an integer type that has a significantly larger capacity (such as a long) for the counter would solve this problem.

Can you see the same issue with 2.8b1? The SSH library used is different in this version.

Issue occurs with both 2.7.3 and 2.8b1.

This looks like a server issue. The error message is given by the server.

Oddly enough the upload worked with CrossFTP, another Java FTP client, as well as sftp. For this reason, I don't think it was the server.

Can confirm this behavior with 2.8 (3256).

As a workaround, I have resumed the transfer using 'rsync --partial --progress'.

I doubt that this is because of the server: the file has been uploaded there from another Mac, by SFTP, using Transmit. Anyhow, for your information, the server's version string is 'OpenSSH_4.6p1 Debian-5build1, OpenSSL 0.9.8e 23 Feb 2007'.

This is definitely a client bug. I was able to upload via the command line sftp client with no problem.

As a workaround you might want to try SCP. Change the setting Cyberduck > Preferences > SFTP > File Transfers to SCP (SSH Secure File Transfer).

Fixed in 7f71989. Sorry this one took so long.

Looking at the descriptions, it seems likely that these two tickets describe the same bug:

Ticket #12457 (closed defect: worksforme)
"incomplete files during SFTP transfer of large directory"
opened: Jun 30, 2006
closed: May 18, 2007

Ticket #1235 (closed defect: fixed)
"Transfers larger than 2**31 (2147483648) bytes fail"
opened: Aug 30, 2007
closed: May 5, 2008

If the bug still existed in August 2007, why was the first ticket closed in May 2007 with "works for me"?
