Hi All,
I am getting "Auth Fail" exception, trying to connect to a linux server which
has SSH-1.99-OpenSSH_4.1 version. My client is SSH-2.0-JSCH-0.1.37
When I connect to a Windows Server, I can transfer files WITHOUT ANY ERRORS
using my application. The windows server has SSH-2.0-OpenSSH_3.8.1p1
Can someone assist ?
Here's the log when the error occurs , to the linux box.
