Can't get Mesa 7i92 to connect without a hub.

Away from the screen now so can't get MAC. .120 ending IP

The little host unit is XCY 1900 with 4 Intel gigabit ports. These are used world wide with pfSence on them for professional high speed routers. So have trouble believing it is the problem. Only using one port at a time and tried them all.

I don't actually like that the only network change you make on Mesa is the IP number.

Never drops a packet.

I didn't mean the Hosts MAC address but rather the type

SInce these are Intel MACS, did you turn IRQ coalescing off?
(it plays havoc with real time)

What OS are you using? (uname -a)

Is it unusual for this to happen prior to loading the hm2 modules ?

Shutting down and cleaning up LinuxCNC...
Running HAL shutdown script
Killing task linuxcncsvr, PID=2050

Also can you post your hal/ini files? there's something odd about the messages as ozzyrob noticed

I didn't know about that IRQ issue.
Ran the following Didn't help anything. (did change ethN to enp2s0)

sudo ethtool -C ethN rx-usecs 0

I saw there were commits on May 10 to correct and add some things with the 7i92 in pncconf including the correct driver. But, can't seem to get that compiled in or running with the changes. Wanted to start with a fresh HAL and INI with the right boards rather than edit things. Anyways, here are my very basic files that I'm trying to make sure the may hardware works before going to crazy adding things.

So the basic hal structure looks OK

Maybe some network setup issue?
what does

print?

Also can you start linuxcnc from a terminal and copy/paste the exact terminal log here? you log looks very strange relative to what I get

You can start linuxcnc in a terminal without launching the chooser by typing
linuxcnc yourinifilename
from the config directory
