My 7i76e arrived today and I am exploring how it works. I have two NICs in my linuxcnc machine. I changed the IP on the 7i76e to 10.10.10.121 because I have 192.168.1.x in my home network. I can ping the 7i76e. but it seems to not respond when I actually run linuxcnc.
Once linuxcnc loads the config, pinging stops responding. When I exit linuxcnc, successful pings resume.
Code:
[code]64 bytes from 10.10.10.121: icmp_seq=17 ttl=64 time=0.111 ms
64 bytes from 10.10.10.121: icmp_seq=18 ttl=64 time=0.087 ms
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
Also, I'm running tcpdump, and I can see packets between my linuxcnc machine and the 7i76e.
So, I am thinking this is normal behavior?
