My SFTP server is running on the Windows.

I was suffering the same problem...
but I solved this problem,
with the restarting of SFTP service.

FYI, my SFTP service is freeFTPd.

i even tried to set the password on the server again and changing protocol and encryption did not make a difference. winscp keeps asking me for a session password while putty works.

Please download the recent version of WinSCP. (For short time, very ancient version was linked from download page by mistake).

I set the ssh daemon on the server on its highest debug level "DEBUG3" and this is what i got when connecting. this is the server log:
debug3: fd 4 is not O_NONBLOCK

this is where winscp permanently asks for a password but no password attempts are shown in the log file. when i press cancel the log just gives me one single line:

debug1: do_cleanup

that's all, no error, nothing. i already tried an other username. also checked the config:
Subsystem       sftp    /usr/lib64/misc/sftp-server

this looks like winscp doesn't even send any password and thinks it was wrong or something like that.

I had a similar problem when I upgraded SUSE. I could login with PuTTY but not SCP. Changing SSH protocol from 1 to 2 fixed my problem also. Thanks.

Re: password trouble

Check the SSH server log file.

password trouble

I have a somewhat different version of this problem. I just changed several Unix server passwords yesterday. I can now telnet into these servers, but both WinSCP and Putty give me authentication errors on these same servers. Do they have trouble with special characters in passwords? I was using "!" in my passwords and I just changed it.
richdog

Has your password changed recently? It sounds as if you have a stored password somewhere in WinSCP that is no longer valid, or your password on your SSH server is no longer valid.

Re: Session password issues

How and where will I get to see the logs that you are talking? I can connect using SSH (Putty) to my Fedora4 Linux server.

Thanks a lot.

Re: Session password issues

First, check the server's log to see why it denies you to login.

Hello,
If I use putty or psftp I can sucessfully login to the server, if I use winscp it keeps asking for session password. I have already entered the user amd pw in the session dialog, what am I missing?

Thanks
