@robert_mil: May I have a test account on your server?
robert_mil

On user interface it stops on something this prompt
robert_mil

I thought that I have similar problem to that descripted in:
Issue 388 – Ignore empty SSH keyboard interactive prompts

I use newest version 4.2.9. It seems that it goes through empty prompt, but stopped on information from server about last login.

THANK YOU THANK YOU THANK YOU THANK YOU FOR FIXING THIS
gublgabl

:D Thanks a lot for fixing it in 4.2.3b!
david strutz

Hmpf, today, yeha – an update, but this (crazy making) bug is not fixed. :(
David Strutz

@martin: Sure, that's right.

I declare that that if people find a bug in a software which they love, try it daily update. :D
martin

Just to reiterate what is already mentioned in the tracker:
WinSCP behaves correctly, it display an empty authentication prompt, just as requested by your SSH servers. Obviously it is bug in your servers. Until 4.1.9 WinSCP was resistant to the bug and just ignored the empty prompts. Until the this behaviour is introduced back to WinSCP (in 4.1.3), either have your server fixed or downgrade to stable 4.1.9.

If it is that big issue for you, I just do not understand why all of you use beta release if it does not do what you want, when the latest stable release does...
David.Strutz

Exactly, but there is more "trouble" because if you use background-transfers, you have to "apply" each "thread".
David Strutz

Hmpf, today, an update to 4.2.2 (480) but this Bug is not fixed. :cry:

I "hate" this "press OK" Dialog since months.

Please fix this.
chli24

workaround for me = installed version 4.05

works fine for me
chli24

I have the same problem in 4.2.2, any workaround?

Got it when upgrading from previous version. I'm using a WinSCP script that has worked for a long time (using .ini file stored pass).

I'm attaching new error – and old working log below.

Any workaround?
Can I install an old version of winscp (and use the new migrated winscp.ini file)?

Thanks in advance
/Christian

Re: Continual "Using Keyboard authentication"

@martin: Well, I downloaded v4.2.2 (Build 480), and still asks for pressing OK :(

How can I disable it???
JanisB

I am using 4.2.2 (Build 480) version with still same problem during connect -
Prompt (5, SSH server authentication, , <no prompt>)

Here I need to click OK for empty "request". Same occurs on file uploading (for the first time messagebox with no content popped up - need to click OK)...

Right.

Re: Continual "Using Keyboard authentication"

Dialog "Using keyboard-interactive authentication" is displayed again, after the password was entered manually, and pressed OK button. It is very annoying.
Is it possible to turn off this behaviour with an option?

This is kind of annoying. Please switch back to the former behaviour.

I'm not asked for a password – I saved that in the Stored Session.

But when the signon reaches "Authenticating with pre-entered password" the bottom 2cm of the window changes to:
Using keyboard-interactive authentication
[OK] [Cancel] [Help]

Where would I find the log?
martin

Re: Continual "Using Keyboard authentication"

So you are prompted to enter a password by keyboard authentication, you do not fill anything and pres OK, right? Before you clicked OK once, now you have to do that twice? Can you post a log file?
Swifty

Continual "Using Keyboard authentication"

Since migrating from 4.1.8 to 4.2.1 (just minutes ago) I've been prompted to click "OK" twice when using Keyboard Authentication.

Is there any way to say that I'll always click "OK", so don't ask?
