I don't understand. You said your user "oub" has id 1000 on the
source laptop, and id 1002 on the destination laptop.
The idea therefore was to have a second user with id 1002 on the
source laptop - I named it u1002, and use rsync via ssh to the
localhost to get the files on the USB drive/stick with id 1002.

of course, that was the idea behind ;-)

You shoulnd't have to modify anything in /etc/hosts.{allow|deny}.
Und unless your sshd is setup correctly, you shouldn't need to
make any changes for that either.

Have a nice day,
