Mesa 7i76e: no board found

Hi everyone,

I need some help getting my 7i76e up and running after a fresh install of the LinuxCNC live CD.
I tried reading through the different posts and sticky, but I'm stuck now.....

Any help would be highly appreciated.

My setup is as follows:
Debian 10 (Buster) with LinuxCNC 2.8.1
ASUSTeK P8H61 Motherboard
Intel Celeron CPU G1620 @ 2.70GHz
2x2Gb DDR RAM @ 1333MHz
Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller

I did manage to disable IP v6 via the terminal:
sudo nano /etc/sysctl.conf
I added a line: net.ipv6.conf.all.disable_ipv6 = 1
I read about the IINTEL adapter issues, but didn't read anything about the Realtek adapters so I didn't do anything to that.

I have the 2 steady amber power leds illuminated on the 7i76e, as well as the green and amber ethernet leds.
The W3 jumper is set to UP.
Wicd Network Manager also shows me as "connected to wired network (IP:10.10.10.10)
I'm cabled straight to the Mesa, and don't have any other network adapter or wireless adapter installed.

I used PNCConf wizard to write 10.10.10.10 as IP address and set the same as fixed IP in the Wicd Network Manager.
Ping and Ifconfig give me the following:

When I try to launch LinuxCNC, I'm getting the following error message:
Debug file information:
Note: Using POSIX realtime
hm2_eth: rtapi_app_main: Connection refused (-111)

Many thanks,
I'm sure I missed something during setup, but don't know what.

Best regards from Brussels,

You have set your PC's IP address to the 7I76Es IP address, they must be different.

I would set the PC IP address to 10.10.10.100

OK,

so it really was that simple (or stupid from me....)

I forced 10.10.10.100 in the network manager as PCW suggested.

This time I can read a good connection via masaflash and ping:

I didn't spend time setting up all the axis, homing and limits yet, but at least I can now start LinuxCNC and move the axis.
That's already a great starting point.

Many thanks to both of you
Really appreciate your help.
