UDP 32766
Synopsis
- rpc.statd (Network Status Monitor) from the nfs-utils package, used by NFSv3 for lock/status notifications, commonly uses UDP port 32766 as its “outgoing” port when fixed ports are configured.
- Real-world examples: on Red Hat Enterprise Linux/CentOS, admins often set STATD_OUTGOING_PORT=32766 in /etc/sysconfig/nfs; on Debian/Ubuntu (nfs-common), rpc.statd can be started with --outgoing-port 32766, and firewall guides frequently open UDP 32765–32766 for NFS locking traffic.
- Security note: rpc.statd has had serious remote vulnerabilities (e.g., CVE-2000-0666), and worms such as Ramen historically probed high ports like 32765/32766 to exploit statd after discovering it via portmapper.
