I want to send files to our SFTP server in DMZ within our LAN. I want to use the server IP address rather than public IP or host name so that the transfers do not require the client to have internet access. I keep getting "Negotiation failed. Server signature is not valid." Is it ok to use server IP address? What is the proper syntax for host names?

btw... tested using FileZilla and that works from the Client PC.

It's OK to use the IP address. However, the "Negotiation failed. Server signature is not valid." error suggests that this is not a host name or IP issue. The connection was successful - the failure occurred while negotiating a secure SSH session with the server. A possible reason is an incompatibility between the client and the server - we can most likely fix this with a bit of your help.

Would it be possible to create a communication log (as described at https://www.rebex.net/kb/logging/) and post it here or mail it to support@rebex.net for analysis?
