Oping doesn't work 3.1.2

Hi there, I just started my own tekkit server with a couple of friends and even when I go into the ops folder and type our Usernames in we still can't op or use op commands. Can anyone help? I have already tried it on multiple servers as well.

shut the server down, edit ops.txt, add your names, start the server. You can't edit the file when the server is running or it will overwrite it when it shuts down.

conversely, from the server console use the op command

Thank you very much. I have to say I didn't think it would be so simple, I feel kind of stupid now lol.
