I do not see any similarity of your problem to the one above. Can you explain this? All I can see is that you are unable to login. That's what I can hardly help you with. You should beter ask your server administrator. Or check the server log file if you are one.

I also am receiving this error, it appears to re-occur with any new user I have added after initial installation. Any help would be greatly appreciated.

Here is a copy of the last user I attempted. Help...Thanks Dave

Unfortunately, I'm working with a shared host. I do have SSH access - I can log in with our master account. But, while I'm allowed to create additional FTP accounts, they don't work with SSH. I thought it might be a problem with WinSCP because the 'xxx@xxx@host' confused me - now I understand it. Sorry to bother you, and thanks for taking your tim to try to figure it out. It most likely is a problem of my host not allowing my additional FTP accounts access via SSH.

While I do not have any server with @ in usernames, it would guess that it should work. If I enter xxx@xxx as username I can see in the log message
! Using username "xxx@xxx".
And I'm prompted for session password for 'xxx@xxx@host'. This is all correct.

I may not understand your problem. Is you username really your email address or it is just your guess?
Are you sure you have access to the SSH server on ftp.seattletech.com?

I'll try to reproduce the problem. If I do not succeed, I'll contact you.

I noticed there is a thread regarding this exact issue from mid 2003 form an old version of WinSCP, but the apparent fix back then was an update to the PuTTY libs - you are now using newer libs than then, so maybe their problem is back?

I am entering a domain (ftp.seattletech.com) and a user (mike) and the appropriate password (this login/pw works when using regular FTP in IE and DOS, for example). WinSCP gets to the authenticating stage, then asks for the session password for "mike@ftp.seattletech.com". Any password I try here fails with the following error:
------------
Using username "mike".
Access denied
Access denied

Server sent disconnect message
type 2 (SSH_DISCONNECT_PROTOCOL_ERROR):
"Too many authentication failures for mike"
------------

I don't have an email account for mike@ftp.seattletech.com, but I *do* have one for mike@seattletech.com. If I enter "mike@seattletech.com" for the login, WinSCP asks for the session password for "mike@seattletech.com@ftp.seattletech.com"

How can I enter an email address as a login (an email address with a different domain that the one I'm logging into)? And why is this session password problem happening (again?)?

I am running Win2K SP4, WinSCP3.68 and 3.7, trying to log into my shared host's FTP (Redhat linux 2.4.25, Apache 1.3.31.

What else do you need to know? I can provide you with the password for the "mike" account I've mentioned in this message.

Thanks!
