OVH Dedicated servers (don't know if this is valid for VPS) have a backdoor for OVH personnel so they can get access to your server. If you want to prevent them from being able to login with root rights follow the following easy steps:
edit /root/.ssh/authorized_keys2 and remove the two lines beginning as follows:
from="213.186.50.100"
from="::ffff:213.186.50.100"
next edit /etc/crontab and remove */1 * * * * root /usr/local/rtm/bin/rtm 10 > /dev/null 2> /dev/null
then rm -rf /usr/local/rtm
BEWARE: do this at your own risk since it violates the TOS from OVH so you might lose your support.
