The HTCondor collector daemon — the directory every machine and job scheduler in a batch-computing pool reports to.
HTCondor is the distributed high-throughput computing system from UW-Madison, used to run batch workloads across university and lab clusters. Port 9618 is registered to condor and is the default port for condor_collector, the daemon that every startd, schedd, and negotiator in the pool contacts to advertise and look up ClassAds. Optionally an installation enables condor_shared_port, in which case daemons share a different single listener and the collector moves with it. An open 9618 means a machine is acting as a pool central manager.
Do not expose
The collector is the control plane for job placement across a whole cluster. Reachable only from pool members, with HTCondor's own authentication and authorization configured — the defaults are permissive.
