How is rsync authenticating?

[morty]

I have two FreeNAS boxes setup, one as my main NAS and the second is for rsync backups.

FreeNAS #1 has two users (me and an rsync user)
FreeNAS #2 has one user (me)

I setup an rsync task on FreeNAS #1 and setup an rsync daemon on FreeNAS #2.

FreeNAS #1 is using the rsync user in the task.

FreeNAS #1 shouldn't be able to authenticate to #2 because #2 doesn't have the rsync user or a rsyncd.secrets file setup, but somehow #1 is successfully rsyncing to #2.

Can someone please explain?

I setup an rsync task on FreeNAS #1 and setup an rsync daemon on FreeNAS #2.

Hi Morty,

Just so we're on the same page, can you clarify what you mean for task and daemon?

FreeNAS has the Rsync Service Modules, is that what you mean for daemon?

And the task, is that a cron job on your other FreeNAS?

Correct.

FreeNAS #1 is using this:

This is how the task is setup:

And FreeNAS #2 is using a module setup like this:

FreeNAS #2 doesn't have the rsync user but somehow FreeNAS #1 is successfully rsyncing to FreeNAS #2.

Any ideas?

After additional troubleshooting, I've nailed it down further. I can create a brand new user on my FreeNAS #1 box, let's call him John. If I make "wheel" the primary group ID for John (even if John isn't actually a member of "wheel", then he can rsync to FreeNAS #2 even if FreeNAS #2 does not have the "John" user added (I'm using local users, not LDAP/Radius/AD).

As soon as I take the primary group ID of "wheel" off of the "John" user, he can't rsync to FreeNAS #2 anymore. It this intended behaviour? It seems like it shouldn't be.

Yes :-(
Freenas support security auth to service rsync ???
