I wanted to establish a RDC from my Windows 7 machine to a remote server (Server version: SSH-2.0-OpenSSH\_7.2p2 Ubuntu-4ubuntu2.4).

I followed and adapted the instructions from:
<http://laptops.eng.uci.edu/software-installation/using-linux/how-to-configure-xming-putty>

Now my RDC works perfectly, but I get the following error log when I try connecting with Putty:

>

I cannot connect for sftp transfers with FileZilla, which is actually my main problem since I can connect to my server using RDC

Any idea how to debug this weird situation ?

Thank you !
