SFTP Smart Services

I 'believe' I had a similar issue and had to reformat the key using this command: ssh-keygen -f <your_key> -m pem

Would the authors of this plug-in consider making this change in SFTPConfig.java?
We were being prompted in the TomCat log to enter a password even though key exchange was being utilized.  Research into the jsch.jar  file showed that we needed to add the below line to SFTPConfig.java.  Would you consider adding that to your base code?

session.setConfig("PreferredAuthentications", "publickey,keyboard-interactive,password");

Hi Santhosh,

I have Checked path is correct and input file is available is was working in the past but now it stopped working with the error i mention. currently the plugin is in 1.8.1 Version can this be the reason?

Thanks,

Hi team!

Using 'Get Remote Directory Contents Over SFTP' smart service we´re seeing the following error:

Could you help us to identify the error?

This communication has been in working until last week, so we know that its not a problem with hostname/username/pw.

Thanks in advance.

Hello andrese378,

Have you upgraded the plugin in recent days? Check for the connection in WinSCP tool with the same credentials provided to smart service.

Thanks

• Added a parameter "Remote file name” in the Send file over SFTP Smart service.
