network configuration.

In that case, I would suggest ignoring the GUI options and doing what the LinuxCNC docs suggest:

linuxcnc.org/docs/2.8/html/man/man9/hm2_...FACE%20CONFIGURATION

ie, edit the interfaces file to force what you want.

(but be sure that you use the correct name for the interface, the example uses "eth1" but yours might well be something else.

To find out open a terminal and issue the command "ip link"

In my case I get And can guess that my hardwired ethernet is eno2 (because I know that wlx40a5ef05a291 is my USB wifi dongle)

I've been researching this today cos I don't seem to have a gui network tool on Debian Bullseye
Try this after you use Andy's trick to find the interface name add this to the file
Then restart the network

I have a question, after I have edited my interfaces file is it normal for the eth adapter status to be down if there is no other device on the network? If I run ifup -a it gives message "file exists ifup failed to bring up enp0s25"  I have not bought the mesa card yet I am just preparing for it.

I think you would be able to ping it but because its not connected to anything it will show as down  (just my guess)

Hi,

I have just received my Mesa 7i96s today from Mr. Andrew Beck of BECK CNC.

I left W4 and W5 at their default setting ( I can't see jumpers ) And I have followed the instructions given in this thread, and I am able to ping it.

This is what I have done:

With the Ethernet cable connected between Mesa 7i96s and Raspberry Pi4

[
behai@picnc:~ $ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether d8:3a:dd:25:8c:37 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DORMANT group default qlen 1000
    link/ether d8:3a:dd:25:8c:38 brd ff:ff:ff:ff:ff:ff
]

I notice that eth0 shows <BROADCAST,MULTICAST,UP,LOWER_UP>

With the Ethernet cable disconnected:

[
behai@picnc:~ $ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether d8:3a:dd:25:8c:37 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DORMANT group default qlen 1000
    link/ether d8:3a:dd:25:8c:38 brd ff:ff:ff:ff:ff:ff
]

I notice that eth0 shows <NO-CARRIER,BROADCAST,MULTICAST,UP>

So I guess my hardwired ethernet is eth0.

Then I log into my home router to verify that 192.168.1/24 is not in used as per the official manual instruction.

I then added the following lines into /etc/network/interfaces:

[
auto eth0
iface eth0 inet static
address 192.168.1.121
hardware-irq-coalesce-rx-usecs 0
]

Then I ran sudo ifdown -a followed by sudo ifup -a, both ran successfully. I.e. they produced no output.

Then finally: ping 192.168.1.121

The response is continuous until I pressed Control + C to interrupt.

I HAVE A QUESTION, PLEASE:

While the pinging was running, I disconnected the Ethernet cable, I expect the response to stop or at least to halt, but it did not. It continues to produce pinging notifications. Is this normal, please?

Thank you and best regards,

...behai.
