I have a Google Compute Engine CentOS 7/Plesk Onyx server instance. Suddenly this morning I see via MXtoolbox.xom notification that my IP is listed in the "SECTOOR-EXITNODES" blacklist.

I looked up what a "tor exit node" is and can't even find this software running on my server, nor any config files.

How can I remedy this?

    Have you had it for very long? The previous user of the IP address may have been running an exit node.

  • I’ve had it since January, and have had this static IP from the beginning. I’ve had a daily blacklist check from mxtoolbox since the beginning too, and today it notified me.

Seems to be a temporary lapse in the sectoor.de DNSBL service.
