assigning eth1 to usb network adapter

[dolphs]

Hi,

 

I added an USB3.0 adapter to my rockpi4a , which results in: " enx000ec667f0a2 " ( eth1 )

 

Since NetworkManager is being used I tried to update this name using : " nmcli c modify armbian connection.interface-name "eth1" "

But alas that does not seem to be picked up while nmconnection config file has been updated:

 

cat /etc/NetworkManager/system-connections/armbian.nmconnection

[connection]
id=armbian
uuid=8f61a97c-d0f1-4cb2-be4a-3fe2b4c08e7c
type=ethernet
interface-name=eth1

<snip snip>

 

Ideally this could be changed in armbian-config, but I realise this is a low-low 

 

 

rockpi-4a:system-connections:# ll
total 1.0K
-rw------- 1 root root 331 Feb  2 12:12  armbian.nmconnection
-rw------- 1 root root 384 Feb  2 11:54 'Wired connection 2.nmconnection'

 

 

That ideally gets changed to 'Wired connection 1.nmconnection'

which I updated manually using " nmcli c modify armbian connection.id 'Wired connection 1' "

 

Idea is eth0 will be used solely for outgoing traffic, while "eth1" will be used for incoming

fantastic, thanks for your answer Igor

I was already about to mess with " 73-usb-net-by-mac.rules ", but this flag works so much better!

 

Out of the box, flashing image it shows:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 86:67:c3:ba:43:ca brd ff:ff:ff:ff:ff:ff
    inet 192.168.10.188/24 brd 192.168.10.255 scope global dynamic noprefixroute eth0
       valid_lft 14213sec preferred_lft 14213sec
    inet6 fe80::f791:3c34:96fb:aec3/64 scope link noprefixroute
       valid_lft forever preferred_lft forever
3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether 00:0e:c6:67:f0:a2 brd ff:ff:ff:ff:ff:ff

Now remaining to configure static address , routing etc etc.

This is my test "system" , so I can configure/ test settings before applying them instantly to my R4S

thanks again!

Shortcut perhaps... but this does override systemd assigning things there...

 

Add the following line to /boot/armbianEnv.txt

 

extraargs=net.ifnames=0

 

and then reboot...
