Raspbian Stretch: Setting a static IP for an USB to Ethernet adapter

[gounthar]

Hi,

I have read quite a few tutorials regarding setting up a static IP for the Pi.
Unfortunately, I haven't been successful in implementing it yet.
My use case is:

• a device is flooding my local network with a video broadcast (my ISP box can't handle it and I lose my wifi network)
• I'd like to use the Pi to catch the broadcast, and reroute it maybe thanks to netcat
• I thought of linking directly the flooding device to the Ethernet to USB adapter... but I don't know if this could work with a straight cable

Anyway... If the straight cable doesn't work, I can still use a small RJ45 switch.

My Raspbian version is:

Code: Select all

lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 9.4 (stretch)
Release:        9.4
Codename:       stretch

The USB to Ethernet device is a ASIX Electronics Corp. AX88772A Fast Ethernet.
I can see it in ifconfig:

Code: Select all

enx00010a0abc98: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 00:01:0a:0a:bc:98  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

The last tutorial I followed is https://raspberrypi.stackexchange.com/q ... 4428#74428.
So my /etc/dhcpcd.conf looks like:

Code: Select all

interface enx00010a0abc98
static ip_address 192.168.0.16/24
static routers=192.168.0.254
static domain_name_servers=212.27.40.241

I must have missed something, as ifconfig keeps telling me that there is no IP address for enx00010a0abc98.
Could anyone help?
Thanks.

Hi,

static routers=192.168.0.254
static domain_name_servers=212.27.40.241

If that is a true representation, you have omitted the equals sign in the IP address assignment line.

Thanks. I corrected, so that I now have

Code: Select all

interface enx00010a0abc98
static ip_address=192.168.0.16/24
static routers=192.168.0.254
static domain_name_servers=212.27.40.241

Unfortunately, I still have

Code: Select all

 ifconfig
enx00010a0abc98: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 00:01:0a:0a:bc:98  txqueuelen 1000  (Ethernet)

        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Does the Ethernet to USB have to be connected to anything to get a fixed IP address?

Mine does. 10.4 on pi4b
