SFTP Public Key Authentication throwing exception.

[Pravin Latti]

Hi,

I am trying to do a SFTP (Public Key authentication) under the UNIX
environment. Using the mindterm.jar for SFTP and am getting the following
exception.

com.line.ifr.exceptions.KException: cannot connect to the remote host

I have provided the private key file for the connection. Also this works
sometimes and throws an exception at times.

Any help will be appreciated.

Thanks in advance.
Pravin.
