Hi folks,

I think I have found a bug in WinSCP. This is my situation:

Ubuntu Server 8.04
OpenSSH 4.7
RSSH 2.3.2

I have configured a specific account for sftp, scp and rsync only. SFTP through WinSCP works but really slow compared to rsync. SCP fails compelety with: http://winscp.net/eng/docs/message_startup_message
I did a log and it seems like WinSCP fails with rssh installed.

I tried scp for the same account from another ubuntu box, it worked flawlessly.
The error is probably in WinSCP.

What can I do about it?

Thanks,

Mike

Please post a full log file showing the problem.

Though you should probably read WinSCP requirements first.

Hi Martin,

I read http://winscp.net/eng/docs/requirements#scp and http://winscp.net/eng/docs/requirements#using_winscp_with_restricted_shell_environments. I guess I suffer from the latter.

This is the log output:
