Subject: About RTNet setup
Date: Fri, 15 May 2020 13:15:32 +0000 [thread overview]
Message-ID: <97020454f0464394b9128a7620d8d631@axelsw.it> (raw)
Good morning,
I'm working in a project where I need send and receive RAW ethernet packet in realtime.
I'm using a Xenomai 3.1 porting on an Ubuntu machine.
RTNet is enabled in the kernel as modules.
The problem is that I don't really know how to setup the network in userspace.
If this mailing list is not appropriate for the issue please tell me where I can write.
The results of rtifconfig is:
rteth0 Medium: Ethernet Hardware address: 6C:B3:11:52:4C:E9
IP address: 192.168.178.142 Broadcast address: 192.168.178.255
UP BROADCAST RUNNING MTU: 1500
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
rtlo Medium: Local Loopback
IP address: 127.0.0.1
UP LOOPBACK RUNNING MTU: 1500
So I tried rtping to ping another machine, in my network: that machine is not a realtime one, and rtping response is that there's no route to host.
The first question is: does the other machine need to run rtnet as well to respond to the rtping protocol, or it's simply a realtime implementation of the standard ping?
The second question is: to send and receive custom ethernet frames from a userspace process,
What is the best configuration of rtnet.conf ? I don't really need rt-tcpip and I don't know how TDMA works.
Third question is about the API to use: I'm trying to see the examples, but I'have some troubles to actually implement this.
I'll appreciate any help
Kind Regards
Marco Tessore
