Otherewise, you may need to rebuild your own version of putty from source, with the pasting feature removed.

Of course, if you cannot stop them from using some other client, that's no good. You cannot control it from the server end. It doesn't know when data's being pasted. Letters are just letters to it.

Many teachers these days use software to compare assignments for similarity. That'd be another way to catch cheating.
Sincerely thank you for your reply.

It seems that copy/paste is available in Putty.

From the server end , I can do nothing for it. So, I should rebuild my own version of putty. For simplicity, my own version putty should not include copy/paste, moreover, it should be uncrypted , because I use it just for studetns' daily programming task, not for crucial data.
Most importantly, I must have a strategy to ensure that I know the students is using my own version putty to connect the server or not.

It's not a easy job, but I want to have a try.

I wish you luck with that project.

Take a look at this:

Configuring PuTTY

See section 4.11.3 which mentions mouse driven cut/paste being completely disabled. I've never tried it myself.

Unless you have a telnet server going, an unencrypted putty would be pretty useless.
