[OpenIndiana-discuss] Holding port numbers for servers

[Jim Klimov]

Uh-huh, thanks Mike, "just what the doctor ordered" ;)
No RFE then :)

I take it, the tunable should be set early in OS startup, i.e.
with some SMF service depending directly on "network" or in an
rc*.d initscript?

The ports thus reserved are subject to usual privileged-port
routines and checks (be root or have the permissions via the
RBAC net_privaddr, SMF and/or zone limit_priv props), right?

Thanks again,
//Jim
