>Release: FreeBSD 3.2-STABLE i386
>Organization:
>Environment:
A box wich connects a lan to the internet via some point to point link.
>Description:
rwho broadcasts its uptime on all interfaces which match either
IFF_BROADCAST or IFF_POINTOPOINT.
On a box with i4b and dial on demand, the packets sent via the isp0
interface trigger dialouts.
>How-To-Repeat:
configure point to point interface up and for dial on demand, then start
rwhod.
>Fix:
Attached is a patch which adds the '-p' option to disable sending packets
on pointopoint links.
While creating the patch, I found out that the variables 'insecure_mode'
and 'quiet_mode' are both not initialized to 0. Shouldn't this be added ?
