Problem with network usb interfaces

[rollomista]

Hi all, i'm newbie on freebsd system.

I need to configure multiple usb network interfaces but any configuration failed. In other words, i would configure name for any interface usb using mac address to match.

I tried to configure /etc/devd.conf, adding these lines but didnt work:

attach 10 {
    device-name "ue0";
    match "mac" "a0:ce:c8:72:d2:fa";
    action "ifconfig_up";
};

Any suggestions? My problem is on multiple network usb interfaces because for each reboot freebsd probe usb and change name

You don't know the device name, that's the one that keeps changing.

Not sure if this would work:

attach 10 {
  match "system"       "USB";
  match "subsystem" "INTERFACE";
  match "type"           "ATTACH";
  device-name "ue[0-9]+";
  action '/etc/myscript'; 
}

But then I don't know how you could match on the MAC address, "mac" doesn't seem like a variable you can use in a match. But you can action a script and do some further parsing there.

Really thanks for answer.

Yeah, I dont know the device name, but i would like setting it by MAC address. My idea is: when freebsd probe usb device and match with mac address, in that moment i would configure device name on usb interface. Is it possible?

Nice idea. I'll try it and reply you.

Sorry for my stupid questions, but this problem hard trigger me

Not a stupid question, it's fairly complex. You're rather limited in what you can use to match, the card's MAC address just isn't there. See devd.conf(5).

I've used a custom devd.conf(5) to report the changing of the CARP state to Zabbix. And it took a bit of fiddling to get it working the way I wanted.

eheh i could only imagine

Anyway i found a solution. I wrote a python's script that parse interfaces and set name and ip by mac address. It's not best solution (imho) but it works!

Thank you!
