Description uitm 2001-02-07 16:10:01 UTC

Setting net.inet.ip.portrange.lowfirst above the value of 1023 fails.
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
