sftp broken by recent updates to debian testing?

Hi,

I am using latest winscp (5.7). I use it to copy files up to my debian server. This is running debian testing (jessie), and after I upgraded with apt-get at the weekend I started getting transfer errors.

I am guessing that this update to libssl2 is the culprit:
http://metadata.ftp-master.debian.org/changelogs/main/libs/libssh2/libssh2_1.4.3-4.1_changelog

I get 'Host is not communicating for more than 15 seconds. Still waiting...'.

I assume your Debian uses OpenSSH server for SSH/SFTP, right? I do not think libssh2 is used by OpenSSH.

Oh well. It was the only recent update in /var/log/dpkg.log with 'ssh' in it:

Please attach a full log file on Debug 2 logging level showing the problem (using the latest version of WinSCP).

upgraded to 5.7.1 - log attached

Thanks for the log. But I haven't found any clue there. It looks like the server stops communicating.
Btw, didn't you upgrade WinSCP about the same time the problem was introduced?

You know, I think I did. I will try reverting when I have a moment (and am at home).

[of course, I am sure the excellent winscp software would not be at fault!]

It could be the same problem as here:

Please test 5.6.2 and 5.6.3, as per:
https://winscp.net/forum/viewtopic.php?p=55603#55603

Thanks, yes you were right. 5.6.1 is okay, 5.6.3 fails.

Thanks.
I have sent you an email with a debug version of WinSCP to address you have used to register on this forum.

Nice Mr Prikryl has fixed my problem, and I have donated some money to him to show my appreciation. I am bragging about it on this forum to encourage others :-D

Support Open Source Software!

Thanks!
