>Release:        4.5, 4.7
>Organization:
Msen, Inc.
>Environment:
4.5-RELEASE-p20, 4.7-RC      
>Description:
Using a virtual web server, with lines like:
ifconfig_lo0_alias19="inet 148.59.66.19   netmask 255.255.255.255 "
in /etc/rc, ntpd will bind to each of the virtual interfaces.  

There is an (undocumented) option, -L, which purports to enable this behaviour, but on our systems we found no way to disable it.  

Further, there is a but in code prior to that which is testing a value that has never been set.  Does not seem to be a problem under FreeBSD but is a bug nontheless.
>How-To-Repeat:
Enable virtual interfaces, start ntpd.
>Fix:
I have a 25 line patch which corrects the problem, including printing debug information where appropriate and documenting the other issue.  I'm not about to post it into a web form though.
