Access violation during sftp connect

[Szpak]

Hi,

When I'm executing sftp connect (SecureFTP plugin) (after enter login & password) I see Access violation at address 00FE83D6. Read of address 00000000. And other info about report to Author.
I saw this error first time after upgrage OpenSSH to 3.7.1 and OpenSSL to 0.9.6k (because of security issues) on my server. I don't have this problem with connect to another server without upgrades.
Is it problem with Total Commander (5.51) or SecureFTP plugin (1.05)? I have Windows XP.

My configuration:
title=Koles
host=192.168.0.1
username=szpak
port=22
home_dir=/
compression=0
use_key_auth=0
dont_ask4_username=0

Best regards,
Szpak

This happens if you have a login script on the server which displays text to the user. Putty has the same problem with SFTP. Solution: Either don't show any text in your login script, or disable the login script for ssh connections.

I didn't know that it's problem with psftp. After Your post I checked it on Putty website and I found that the other way is to disable "ChallengeResponseAuthentication" in sshd_config. This problem shouldn't exist in 2002-08-04 snapshot.

Thanks for help

This happens if you have a login script on the server which displays text to the user. Putty has the same problem with SFTP. Solution: Either don't show any text in your login script, or disable the login script for ssh connections.

For the record, while SFTP has worked flawlessly for months, we just upgraded to:

OpenSSH_3.7.1p2, SSH protocols 1.5/2.0, OpenSSL 0.9.7c 30

And the plugin now fails. There's no login script text.

Putty SFTP (not PuTTY), works fine.
FileZilla SFTP works fine.
Total Commander with the SFTP plug-in fails.

The SFTP plugin needs to be upgraded and I've written
Hans-Juergen Petrich (the author of SFTP) about this.

Here's the error message:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Access violation at address 01E07966. Read of address FFFFFFFF.
Please report this error to the Author,
with a description of what you were doing when this error occured!
Continue execution?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Continuing just locks and thus crashes Total Commander.

Even if the plug-in fails, it would be better if the program didn't crash.

The plugin was last updated November 2002. It's 2004 in a week or so.

Please let me know if the author of the plugin doesn't reply.

Please let me know if the author of the plugin doesn't reply.

It's been a month. No word from the author.

Thanks...

OK, I will try to contact him myself.

I have the same problem.
Is there already a solution for this problem?

[ghisler(Author)]

He promised to have a look at it, but didn't report back yet. Did you make sure that the login script doesn't display any text?

[jwchess]

Yes, I'm sure that the login script doesn't display any text.

It's really frustrating, because on my new server I can't user TC now, but I have to use WinSCP now.
When you're used to TC, it's a great step backwards....
