SFTP and hash comparison

Question

Hi

We use syncback to deploy our software through SFTP. (We recently migrate from FTP to SFTP and we use a old version (12) of Serv U.)
We realised afterwards that Serv U does not support hash comparison combined with SFTP, does your software ?

Thank you !

Answer 1

CompleteFTP does have an extended SFTP command that allows you to calculate the CRC of a remote file (or, from 8.1, the CRC of a segment of a remote file).

You would need to code your client to be able to send this extended command (it is an SSH_FXP_EXTENDED message).

Answer 2

This command can also be called via an SSH session.

Additionally you can add your own commands via either a JavaScript script or a custom-written .NET extension.
