"Ctrl + C" will cancel the ping operation. And yes, of course, replace the example 10.x.x.x with your card IP address.
$ ping 192.168.1.121
"Ctrl + C" after 2~3min, post packet loss and stats
$ sudo ping -f 192.168.1.121
"Ctrl + C" after 2~3min, post packet loss and stats
$ ping 192.168.1.121
"Ctrl + C" after 2~3min, post packet loss and stats
$ sudo ping -f 192.168.1.121
"Ctrl + C" after 2~3min, post packet loss and stats

The forum software is driving me crazy.
I don't understand in the manual how I have to set this so that the card speaks to 10.10.10.10.
Quote from the manual:
HARDWARE CONFIGURATION
IP ADDRESS SELECTION
The 7I95 has three options for selecting its IP address. These options are selected
by Jumpers W16 and W17.
cnc@debian:~$ ping 192.168.1.121
~3min
$ sudo ping -f 192.168.1.121
~3min

The forum software is driving me crazy.

That looks beyond perfection. Can't see what else could prevent you from running Lcnc.
Side note. In my case, and to resolve the start-up and occasional random "Unexpected realtime delay on task 0 with period 1000000", and other follow errors (!), I had to upgrade my decade old ghetto 10/100 hub to a fast switch and also upgraded old cat5 to double-shielded Cat6 grade ethernet cabling.
That, along with the GRUB_CMDLINE_LINUX_DEFAULT="quiet, isolcpus=2,3" tweak solved the random low latency and packet losses. Never had a realtime delay after that.

That's a good tip about the cable. I'll have to see what I use there. I think it's all shielded.
I didn't understand that, do I need to raise or lower it?

I have LinuxCNC open right now and I don't get any errors for several minutes, I'm happy.
Hope it stays that way.

I hope I'll remember all this if, for whatever reason, I have to set up the machine again.

Another useful one to keep track of thread(s) performance and/or debug. Run cmd below while Linuxcnc is running to peek into various delays.
$ halcmd show param *.tmax
All the best to you and Have Fun!
