Sniff the network #11

Closed LanderU closed 7 years ago

LanderU commented 7 years ago

Hi!

I have some troubles to capture the packages between CX9020 Linux master with etherlab and ccat configured.

My configuration:

CX9020 --> EK 1110 --> LAN9252

I'm able to sniff the EtherCAT packages using, "man on the middle" technique, but the intermediate computer is not real time machine and I have some delays.

Is it possible sniff directly on mater? How?

Thanks in advance!

Also, is this device CU2508, compatible with the Linux master?

I would use an ET2000 for sniffing

CX9020<->EK1110<->ET2000<->LAN9252
                     |
                 PC (Wireshark)

Sniffing on the master might be a little tricky, as EtherLab doesn't announce it's devices to the Linux network stack.

In general, you would have much more luck with your questions on the EtherLab mailing list. They are much more experienced with EtherLab and EtherCAT on Linux. And they have an answer to the CU2508 compatibility: http://lists.etherlab.org/pipermail/etherlab-users/2015/002727.html

If you have further questions, feel free to ask. If it is related to EtherLab, try to post on their mailing list. I read that, too, and will respond, if I have an answer: http://lists.etherlab.org/mailman/listinfo/etherlab-users
