--Apple-Mail=_7E006F21-DE41-4510-B130-8D42DEE5F776 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 Hi everyone, I have been using jails with VNET since about 10.1 or 10 and have so far = not encountered any huge problems except for accidentally giving two = jails the same epair which broke my stack. But today I did encounter a = problem. The problem i encountered was where one of my jails would lose all = connectivity when starting another jail, after some investigation it = turned out that both jails had the same MAC address. I=E2=80=99m not = aware of how these MAC addresses are generated but this seems to be a = bug, as I=E2=80=99m not manually assigning MAC address. In the attachments you will find my jail.conf and the ifconfig output of = both jails. I hope someone can help me with this and/or give me some insight as to = how the addresses are generated.
