Apparently sysctl syscall doesn't give any indication of error when trying to change lowfirst to anything greater than 1023, but actually this operation is not completed (see 'how to repeat the problem'). I didn't come to any fix to sysctl syscall or utility yet. >How-To-Repeat: uitm# /sbin/sysctl -a | grep port vfs.nfs.nfs_privport: 0 net.inet.ip.portrange.lowfirst: 1020 net.inet.ip.portrange.lowlast: 600 net.inet.ip.portrange.first: 3072 net.inet.ip.portrange.last: 5000 net.inet.ip.portrange.hifirst: 49152 net.inet.ip.portrange.hilast: 65535 uitm# /sbin/sysctl -w net.inet.ip.portrange.lowfirst=3071 net.inet.ip.portrange.lowfirst: 1020 -> 1023 uitm# /sbin/sysctl -a | grep port vfs.nfs.nfs_privport: 0 net.inet.ip.portrange.lowfirst: 1023 net.inet.ip.portrange.lowlast: 600 net.inet.ip.portrange.first: 3072 net.inet.ip.portrange.last: 5000 net.inet.ip.portrange.hifirst: 49152 net.inet.ip.portrange.hilast: 65535 >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
