I'm puzzled that your linux server doesn't have ssh and yet you connect on port 22... But, I only know of SecureFX what I've just read on its website.

I think the first thing you should do is set up a key so you can connect without entering a username and password. SecureFX's website describes a Public Key Assistant for uploading a public key to the server.

If you can get that going, and if SecureFX has a commandline interface, you could just call it from your script, with the appropriate arguments.

For similar tasks, I've used PuTTY's pscp.exe and pagent.exe. From perl, call the latter to load your key locally; and then call pscp.exe with the local file path and the remote destination.
