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.

We have an application that allows users to login and submit/receive files
through a custom FTP proxy server. We support most FTP clients. We now
need to be able to support an SCP client (such as WinSCP). I thought it
might be possible to use OpenSSH's sshd as an SSH wrapper for my FTP proxy
server. What I want to do is perform an ftp connect at session start, an
ftp login for password authentication, and then an ftp put or get for
sending or receiving files.
Is this a bad idea? Is there a more straightforward way to accomplish
I'm working my way through the code, but could you provide some guidance
the locations where I would need to add in my FTP logic as describedabove?
Thanks in advance for any help.
