https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229957 --- Comment #4 from O. Hartmann <ohartmann@walstatt.org> --- (In reply to Eugene Grosbein from comment #1) epair(4) interfaces are created in /etc/jail.conf within the "common" porti= on of the config file via [...] exec.prestart=3D ""; exec.prestart+=3D "ifconfig ${if_vnet} create"; exec.prestart+=3D "ifconfig ${if_vnet}a ether ${epair_ether_base}:0= a"; exec.prestart+=3D "ifconfig ${if_vnet}b ether ${epair_ether_base}:0= b"; exec.prestart+=3D "ifconfig ${if_vnet}b up"; exec.prestart+=3D "ifconfig ${if_home_bridge} addm ${if_vnet}b up"; [...] Each jail definition has a set of variables comprising ${if_vnet} from lite= rals "epairXXX" and then in the prestart section a and b.=20 ${epair_ether_base} is set to something "hand-randomised", means I try to g= ive each epair a distinguished MAC after I ran into these problems. So accordin= g to your question, epairs are created as walking through a for-loop, creating e= ach epair and put the a-part into the vnet jail and going on with the next. I f= ind this way much more convenient than creating all necessary epairs at once and putting them afterwards into vnet. --=20 You are receiving this mail because: You are the assignee for the bug.=
