Hi,

I am doing a FTP from a Unix host to a windows host. I have generated the key in my unix server and added them in the destination host. In the Destination they changed the ip address now i am not able to connect. I can see it is reaching till that server but i am not receiving that server certificate. Below is the error message.

firenze$ /Application/PSOFT/.ssh:/opt/boksm/bin/sftp -o port=9900 ext-amat@158.156.156.86
Connecting to 158.156.156.86...
