Well it does.
So please let me know if you find anything new.

Hello,

thank you for your reply.

When I add the /privatekey=... option to the commandline the connection is established.

It looks as if the .com in this special cace does not recognize the PublicKeyFile setting in the WinSCP.ini

I will let you know when I find anything

In the log file showing unsuccessful connection, there were no key:

So that may be an answer.

Hello Martin

thanks for the replay.

When I start winscp.exe from the desctop I am able to connect and send and receive files. (just using the key stored in the .ini file)

When I start winscp.com from the desctop in a commandshell just using the same settings and key as winscp.exe I get the message "No supported authentication methods available" as mentioned before after entering the username.

When I start Pagent, enter the key into it and start winscp.com from the desktop in a commandshell it is able to connect and send / receive files.

The target is that the winscp is called by a windows service in the background. Unfortunatly it is not able to connect to the Pagent.exe. Currently all other connections work and are using the keys stored in the ini file of winscp.

I hope my problem is a bit more clearer now.

Thank you

Dirk

I'm still bit confused by the description of the problem. Thought, to me it looks like the server has only private key authentication allowed. And as you have not specified any key, nor running pagent, the authentication fails. Would it explain your issue?

OK,

I updateted to 4.1.8 with the same result.

Re: Scripting: Login problem when not using Puttyagent

Thank you for your quick response.

This is the log of winscp.exe succeeding the conection. Pagent ist still running from the tests before. It has no keys inserted.

My problem for testing winsft with diffrent versions is that that computer is the only one in our network with full access to the required ports.

If there is no idea what to do the next step will be to update to the newes version of winscp.

Re: Scripting: Login problem when not using Puttyagent

Please post a WinSCP log file. Ideally with the latest version.
DGorthat

Scripting: Login problem when not using Puttyagent

Hello

We are using winsftp.com for several automated sftp filetransfers. This works stable and reliable since months.
These are running in a windows service in the backround process on a windows 2000 machine.
That service creates a .cmd file and the winscp script file in a temporary directory and executes them.
WinSCP.exe ist setup to store the configuration in its .ini file so that even the keys are reachable
for the winscp.com executable.
This configuration works for 9 diferent hosts since months with no problems.

Running sftp scripting in a windows service runs into a login problem on one server.
The service is logged in with the same account as the windosw user I am testing the connection with WinSCP.exe.
Login with WinSCP.exe works and I can send and receive files.
But even when I try to use WinSCP.com manually I get the following log directly after entering the username: 
batch        on        

confirm      off       

Suche nach entferntem Rechner...

Verbinde mit entferntem Rechner...

Authentifiziere...

Verwende Benutzername "xxx".

No supported authentication methods left to try!

Die Verbindung wurde unerwartet geschlossen. Der Server sendete den Befehlsbeendigungsstatus 0.

Anmeldungsprotokoll (Siehe Sitzungsprotokoll für Details):

Verwende Benutzername "tcc".

No supported authentication methods left to try!





Anmeldung fehlgeschlagen.

Keine Sitzung

That is the same result I get in the log, when I run the service.
But:

When I use Puttyagent to enter the key into it, I am able to log on to that host with winscp.com manualy.
The service is running under the same windows account is still not able to connect and leads to the same error (see above).
I assume winsftp.com is not able to connect to the pageant.exe because it is another session.

We are running 4.07 Build 370

Thanks in advance for any comment

Dirk
