This is probably a simple one for all you Unix whiz' out there, but I can't figure it out, so I am trying to sftp into a windows server from the command line, and the remote refuses connection. When I run it in verbose mode, I can see that the system is trying to use one of my public keys (set up in my ssh config and used for another server that I ssh into) for authentication, when all I want is for it to ask me for a password, here is a sanitized version of the trace:

sftp -v<username>@<remote_ip_address>

When I try this on a windows machine with WinScp or Putty, things work just fine. But I need to get this working on my production server (Centos) where I can't install these or another utilities. PS: Im able to reproduce this problem on my mac as well, with the same result, but can't resolve it on either. Any help would be appreciated. Thanks in advance!!

Try:

sftp -o PubkeyAuthentication=no <user>@<server>

That should disable the will of using your public key for this session.
