greetings, when using xen, the network interface of the machines usually have the mac ff:ff:ff:ff:ff. untill now i didn''t care but our hoster today locked down 15 machines claiming this is spoofing. Is there any reason xen doesn''t use the native mac? can i set it manually somehow? thanks. -- best regards Arvid Ephraim Picciani _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I choose another nic and there was no problem. Now i setup xen 3.2, gentoo kernel 2.6.20, etch dom0 and realtek 8169 and until now i never seen the issue again. The only thing that works for me was to make a init script like (excuse my dirty workaround): ifconfig eth0 down ifconfig eth0 hw ether "my real mac" netmask 255.255.255.224 broadcast 78.xx.xx.xx up route add default gw 78.xx.xx.xx greets Holm _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

It appears the software is doing it without your consent, I see.
