While setting up rsa key based authentication i'm getting public key exception.

Question

Hi Team,

I have downloaded RebexTinySftpServer-Binaries-Latest and trying to setting up my console application to test the sftp client using rsa key based authentication but i'm receiving the below error:

Rebex.Net.SftpException: 'A public key corresponding to the supplied private key was not accepted by the server or the user name is incorrect.'

I have seen most of the Q/A asked in forum but it couldn't help me. so, I need you guidance to solve it asap.

Regards,
Mayank

Hi Mayank,

Could you provide us with relevant part of the source code (client) you are using, as well as Tiny SFTP Server configuration? Use support@rebex.net if you prefer. Also make sure to remove any sensitive information, e.g. private key (unless not used anywhere else and you plan to replace them).

Hi Lukas,
I have shared the required details yesterday to support@rebex.net, have you got a chance to look into it.

Hi Mayank,

We haven't received any email from you yesterday. Can you please double check the address you used and try again?

Hi Lukas,
I'm sending a copy of it, again to support@rebex.net.

Hi Mayank,

On the server side, make sure you set the following values in RebexTinySftpServer.exe.config correctly:

• userName matches the value used in the client
• userPassword is set to "" (empty string)
• userPublicKeyDir is set to a directory where user's public key is saved (check there are no warnings when you start the server)

Setting Log level to Verbose might also help to diagnose the issues.

Hope this helps

Hi Lukas,

Can you please confirm me, have you looked into the source code and config file which i have shared with you.

Hi Mayank,

As already answered in the email, we haven't received any email with attachments. We can provide an alternative, e.g. SFTP drop, if you are interested. Please contact us via email.
