Bug ID: 255294
Summary: augment if_tuntap man page on source of autogenerated
MAC (/etc/hostid)
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: conf
Assignee: b...@freebsd.org
Reporter: p...@freebsd.org
ifconfig tap0 creates a tap0 device with a seemingly random MAC. The MAC comes
from /etc/hostid -- if somehow the /etc/hostid was cloned during multiple
instances, the MAC will be the same, which will cause trouble in VPNs.
