ASP, need to use SFTP

Question

This is ASP classic, not .Net. We have to get a way to SFTP into a server to upload and download a couple of files, kicked off by a user.

What have other people used to do SFTP in ASP classic? Not necessarily opposed to purchasing a control.

Answer 1

If you have the ability to use WScript.Shell then you can just execute pscp.exe from the Putty package. Obviously this is less then ideal but it will get the job done and let you use SCP/SFTP in classic ASP.

Answer 2

The way I have done this is to create a command script file and pass this on the command line via the /b command to psftp.exe. I have also tried this in Perl and have yet to find a neater way of doing it.

There is an issue with this method, in that you already have to have accepted the RSA finger-print. If not, then the script will either wait for user input to accept it or will skip over it if you are running in full batch mode, with a failure. Also, if the server changes so that it's RSA finger-print changes (e.g. a cluster) then you need to re-accept the finger-print again.

Not an ideal method, but the only one I know.

I shall be watching this question incase anyone knows another way.

Answer 3

I used to do that with FTP on windows (create a file of commands and shell out FTP.exe)

Xetius I tried to upvote yours and accept your answer too and I received an warning that I needed 25 rep to do that. Sorry.

Answer 4

I've previously used a component from here: www.weonlydo.com. I didn't find it the easiest piece of kit to develop against but it got the job done in a hurry.
