They are picked up from a special range. It's been this way forever, AFAIK. One "solution" is to request a fixed port for each RPC-based service if a service provides such option. Another solution is to play with lowlast / lowfirst sysctl-s under net.inet.ip.portrange. Another potential solution is to exclude all well-known ports (/etc/service= s) from RPC's use. That would automatically work for all but there can be some challenges. If you are curious, please see IP_PORTRANGE_LOW in the source code. --=20 You are receiving this mail because: You are the assignee for the bug.=
