[solved kinda] New NIC names not being used

jrussell · 2013-03-26 10:01:59

Hi, I have 3 arch computers and 2 of them have the new NIC names from systemd-197. Im struggling to get this to work on the last one.

Ive read this https://bbs.archlinux.org/viewtopic.php?id=156283&p=1 but cant find any help.

I have deleted the file /etc/udev/rules.d/80-net-name-slot.rules which I think overrode a rule somewhere else to prevent the change? So I should have the new names after removing that file?

yet

jason@jason-laptop ~ % ip addr                                    
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN

    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
    link/ether 00:1d:09:a8:ae:1d brd ff:ff:ff:ff:ff:ff

    inet6 fe80::21c:26ff:feca:be4b/64 scope link 
       valid_lft forever preferred_lft forever

Any ideas?

Just to make sure, you did actually reboot or trigger udev after this, yeah?

tomegun · 2013-03-26 23:53:28

What is the output of:

$ udevadm info /sys/class/net/eth0

and

$ udevadm info /sys/class/net/wlan0

?

I have rebooted many times Actually deleted the file a while back, only noticed there was no change the other day, Im using NetworkManager.

Ah, so it appears we don't yet support the ssb bus (only the bcma one). Are you able to patch and compile systemd? If so could you test this patch: https://dev.archlinux.org/~tomegun/0001 … uses.patch ?

jrussell · 2013-03-29 09:44:42

I've never done anything like that before, but I'll give it a go.

tomegun · 2013-03-29 12:12:05

@jrussell: i had a look at this, and it appears that he ssb subsystem in the kernel does not support predictable network interface names. So even if my patch might appear to work, I don't think it will end up being a good idea (as the names might actually end up changing randomly after all).

What you could do instead, would be to use the macadress. Make a copy of /usr/lib/udev/rules.d/80-net-name-slot.rules in /etc/udev/rules.d and add the line:

NAME=="", ENV{ID_NET_NAME_MAC}!="", NAME="$env{ID_NET_NAME_MAC}"

Alright thanks, its not a problem with me, I dont actually need any renaming, I was just curios as to why it was not working
