Guaranteed Transmission Protocols For Windows?
Michael writes "Part of our business at my work involves transferring mission critical files across a 2 mbit microwave connection, into a government-run telecommunications center with a very dodgy internal network and then finally to our own server inside the center. The computers at both ends run Windows. What sort of protocols or tools are available to me that will guarantee to get the data transferred across better than a straight Windows file system copy? Since before I started working here, they've been using FTP to upload the files, but many times the copied files are a few kilobytes smaller than the originals."
I don't know SSH (which SFTP uses) well enough to say that you're wrong, but I think you are. Encrypting software, in itself, does not guarantee that there are no errors. It's a simple case of garbage-in-garbage-out.
On the other hand, use of SFTP in place of FTP is mandatory in this day and age. FTP sends passwords in clear; anybody using it is wearing a big red sign that says HACK ME!!!!
As for data integrity, this is not exactly new, or rocket science. Here's the magic word: checksum.
Nothing wrong with the protocol
Sorry, but any protocol that corrupts data because a notepad.exe compatibility switch was set the wrong way is just completely fucked up.
