Is there a way to see the IP from which a specific post was made?
I don’t think Discourse tracks IP at that level. As far as I know it only tracks it by Registration and Last Login/Visit on the User, not on a post/topic.
Huh. I’m surprised. Per post/topic IP logging would help to see if an account was compromised.
Again this is needed for security or even legal reasons, as if some entity requests the IP from where the msg was posted from
It would be a good idea if we recorded the IP with each post. Do we have the data structures in place to do this, @zogstrip? Maybe as a post actions or post history table column?
Yeah, each post revision should store the ip that created it.
Perhaps also consider storing if an API key was used in combination with the IP to create the post, this might aid in any clean up as a result of an API key abuse - either a users or the master API key.
I revive this old topic. Is it still so that it’s not possible to determine from which IP address a post was sent from?
Seeing that nobody answered, I suppose it is not possible.
I am asking because this week a regular user contacted us admins at our forum. (This is something any admin could run into so sharing the experience is smart.) He told that he hadn’t written a post which had been posted from his account. Obviously I killed all his active sessions and forced him to reconfirm his email. The email hadn’t been changed btw. That could be deduced by looking where the system had previously sent email digests (a nice tip!). The user told that he also changed his password so he should be safe from future attacks.
It is weird that the post was nothing offensive or “funny” or anything that you might be tempted to post on someone else’s behalf. It was a proper post on a proper topic! It would make no sense that someone would work to hack his account just to publish that post.
So probably someone had access to a device where the user had a live session going or the user had saved his password to a browser. But the user denies that: he claims that he uses the forum only with his phone and his PC. He says that there is no chance someone had access to those.
We have no clue of how we could gain more clues of what happened. Seeing the IP address from which the post was sent from would be a nice hint.
Assuming it was recent you can just grep for his username in the nginx logs.
zgrep username /var/discourse/shared/standalone/log/var-log/nginx/access.log.*.gz
