I copied the example from http://www.freedesktop.org/software/systemd/man/systemd.link.html.
Here is the full example: [Match] MACAddress=12:34:56:78:9a:bc Driver=brcmsmac Path=pci-0000:02:00.0-* Type=wlan Virtualization=no Host=my-laptop Architecture=x86-64 [Link] Name=wireless0 MTUBytes=1450 BitsPerSecond=10M WakeOnLan=magic MACAddress=cb:a9:87:65:43:21 > ...still appears to be matching by MAC? Or am I misunderstanding, and > the [Link] section doesn't control which name is assigned to which > interface In this example we have two "MACAdress" lines. The first line (in the [Match] section) is for matching the interface by MAC. The second line (in the [Link] section) is for altering the MAC of the interface (MAC spoofing). > That's not exactly the question I was asking, but maybe I'm missing something. Sorry, my fault. I think the easiest solution would be to have no "Name=" line in the config file. Did I get it right now? > With the config file you have above, and a > static IP set, does systemd issue a SIOCSIFNAME ioctl against a socket FD? If > so, what string is in the ifr_newname char array? Actually I don't know how systemd is accomplishing this task (I would have to read the sources first). But I guess that if_newname = "wireless0" (if systemd uses SIOCSIFNAME ioctl). > And either way, what "ip addr add v.w.x.y/z dev XXXXXX" would systemd run to > add the fixed IP to the interface? (Or if it adds the address itself via > netlink, then (a) why doesn't it use standard tools to do configuration, (b) > does it actually support multiple addresses per interface like ip does, and > (c) what name does it dereference to an ifindex for the ifa_index arg to the > netlink message that it sends to add the address?) I can't give an answer for (a) and (c). But I can say that systemd supports multiple adresses per interface. The description of the "Address=" line says: "This option may be specified more than once." -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
