Restart != HUP
Sheldon said that inetd had to be killed and restarted for the changed to take
effect (ie a HUP wouldn't work). He later explained that it was because the
inetd in 3.2-RELEASE scrambles its conf file when it is HUP'd.
Maybe this commit message is it..
----------------------------
revision 1.9
date: 1999/06/17 09:16:06; author: sheldonh; state: Exp; lines: +2 -2
Various fixes for inetd's TCP Wrappers support:
1) Handle forking and non-forking internal services correctly.
Turn on wrapping for internal services because it works now.
2) Preserve server names for each service on HUP.
3) Honour hosts_options(5) severity option.
4) Add IMPLEMENTATION NOTES section to clarify TCP Wrappers
usage and limitations.
This change may cause previously allowed builtin services (e.g. daytime)
to be denied in existing configurations.
