RE: OpenSSH and FTP
I understand what scp does, but the issue here is that our ftp proxy is
completely custom. It authenticates the user against an oracle database,
and performs TCP/IP communications with another process to determine the
location of a virtual directory to place and retrieve files for the user
logging in. So, I can't just use SCP without our ftp proxy. That is why I
was looking for a way to have the sshd process interact with our ftp proxy.
As for sftp, I agree that it would be a better fit, but we are locked into
using an scp client because of a customer requirement.
Thanks to all of those who have responded to my question. It looks like the
consensus so far is that it is not a good idea to attempt this.

If you need to download/upload files,I think you can do that just with
scp, you can remove ftp and use just scp, rhe problem is that no much
people is familiarized with scp ( I don't know why!! Is a very common
tool), Otherwise, why don't you chech the new feature in Openssh sftp,
it is included in the new version.
