Technical Details

what runs on :9618

The collector uses HTCondor's CEDAR protocol over TCP and UDP, with TCP commonly handling queries and longer exchanges while daemons can send advertisements over UDP. Messages contain serialized ClassAd data and collector commands; authentication, integrity, and encryption are controlled by HTCondor security-policy settings rather than being inherent to the port. Port 9618 is the standard collector port, while other HTCondor daemons may use configured or dynamically assigned ports.

security overview

A collector exposed to the public Internet can disclose pool membership, host details, resource availability, and job metadata. If HTCondor authorization and authentication are weak or disabled, an attacker may inject or manipulate advertisements, interfere with matchmaking, or probe collector operations; collectors should normally be restricted to trusted pool networks and protected with the site's HTCondor security policy.
