#52 Problem with SSH-2 RSA

[Anonymous]

Hi,
I am having a problem when trying to connect to a
server with SSH connection. I can login the server
firewall without any problem by using the putty with
the private key generated by puttygen. But when I copy
over the private key into BVRDE folder and rename it
to different kind of filenames (private.key,
private.key.ppk, private.ppk), leave the password
field empty, click the Test Connection and enter the
password, it cant let me to login. The error message
display user is not authenticated. Any idea on this?

Thank you.

The problem semms to be in openssh server, not in BVRDE.

Since openssh was updated to version 4, the openssh server starts to refuse connections from crypto lib, which is used by BVRDE.

I do now know if bug is on Crypto Lib or in openssh.

To fix that problem, just downgrade your openssh version to 3.9_p1-r3.

it seems that the problem is in current realization of OpenSSH (6.7)

Please look at this link:

Matthieu Wipliez did the trick.

this is the end of sshd_config which works for current version of bvrde 1.3a (cryptlib 3.3.0)
