https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D223151 --- Comment #2 from Yuri Pankov <yuripv@gmx.com> --- Originally, it was a request on IRC asking how to *programmatically* find t= he original name of renamed interface as some tunneling software wanted the tun device, not the newly named interface. I understand that it's not a usual use case, but in any case seemed helpful enough to implement (I didn't find any other way) -- if it isn't or there a= re smarter/easier ways to find the original name, feel free to reject this. The output now looks like the following (with devname listed only for renam= ed interface): # ifconfig tun0 create name foo foo # ifconfig vmx0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 =20=20=20=20=20=20=20 options=3D60039b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,TSO= 6,RXCSUM_IPV6,TXCSUM_IPV6> ether 00:50:56:00:00:34 inet6 fe80::250:56ff:fe00:34%vmx0 prefixlen 64 scopeid 0x1 inet 192.168.1.34 netmask 0xffffff00 broadcast 192.168.1.255 nd6 options=3D23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL> media: Ethernet autoselect status: active lo0: flags=3D8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 options=3D600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6> inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2 inet 127.0.0.1 netmask 0xff000000 nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL> groups: lo foo: flags=3D8010<POINTOPOINT,MULTICAST> metric 0 mtu 1500 devname: tun0 options=3D80000<LINKSTATE> nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL> groups: tun --=20 You are receiving this mail because: You are the assignee for the bug.=
