Finger Print error in SFTP receiver adapter

[Former Member]

Hi Experts ,

     I am getting following error in SFTP receiver channel, here I have nominated the password based authentication rather than certificate authentication method in channel. And I have created finger print in NWA and shared with SSH server admin to import , then I maintained the same in my receiver channel also. And I have done the vice-versa created the finger print in SSH server side and given the same in channel . Still error is persist in channel, experts please suggest .

Error :

Message could not be forwarded to the JCA adapter. Reason: com.jcraft.jsch.JSchException: Fingerprint invalid. Fingerprint is: 6b:f4:38:e7:13:31:59:c8:76:4f:e1:93:10:ac:73:ca

Hi Raja,

Get the valid fingerprint from SFTP owner.

Also try to login from FileZila or Some other FTP client.

Hi Raja,

They might shared wrong fingerprint, If you configured first time in Filezilla it will show the finger print. Check with SFTP owner to share correct fingerprint.

Please use the xpi inspector to trace the root cause. It should give you additional information..

then I export with PKCS#12 Key Pair format and shared to SSH admin, respectively he shared his server fingerprint , that i have maintained in ID. then it works

>>>> Though i'm not sure how it works, you can validate the fingerprint of the FTP server with one which is configured in the channels.

If you have file zilla/coreFTP try to connect with the credentials and then you'll get a pop-up which should have the finger print information.

As i said, just try to connect to your FTP server from filezilla using the credentials. (FTP client - search and download)

You'll get a popup which will display the fingerprint. Copy and paste the same in your channel.

Are you sure the port number is 2222?

Normally port for SFTP server should be 22

[former_member184720]

Did you copy the finger print from filezilla and configured the channel?

Make sure there are no typo's.

If you feel that the configuration looks good, please trace the channel using XPI inspector.
