Hi,

I would like to have some sort of logging that shows me the IP address / login data of a user in order to fight abuse. Has anyone modified the default configuration of RC and made this possible?

Any help is really appreciated!

Stef

Hi Chatdev, you could do this quite easily as an external node app, using the SDK to setup a callback on system messages, spawning your script when message objects have `uj` or `ul` type properties (user join / leave).

Might also be a case for a Rocket.Chat App. Hopefully you’ll see some examples of those soon. I think there’s a feature request thread for apps on the forum. You could suggest it there.

Ok thanks Tim. I am not a specialist but I will look into it. Love the Rocket Chat software!
