Hi, I am running rtnet-0.6.1 on an embedded PC with kernel 2.4.18, rtai 24.1.11 and an intel 82559ER ethernet controller (use eepro100-rt). I'm looking for a better realtime behaviour of a periodic 2.4kHz UDP data output over a cross cable to my host PC (peer-to peer). On the other hand I need a TCP (telnet) connection for control issues to the embedded system. In this case I can live with some influence to the UDP output.
This should work with plain rtnet (UDP, ARP, ICMP) and rtnetproxy (TCP)? I set up rtnet using: rtifconfig rteth0 up 192.168.169.135 netmask 255.255.255.0 rtifconfig rteth0 route solicit 192.168.169.60 #my host after that I can ping the rtnet box from the host, but with some lost packets. With each lost packet I get this message on the rtnet box: RTnet: Host 102.168.169.0 unreachable (from 192.168.169.135) RTnet: error in route daddr a9a8c0 saddr 87a9a8c0 ok, nevertheless I loaded rtnetproxy and set it up: ifconfig rtproxy up 192.168.169.135 netmask 255.255.255.0 Now I can ping the host from the rtnet box, but without reply. This is OK because received icmp is not passed to rtproxy, I think!? Can see the replies with tcpdump on the host. Trying telnet becomes strange: Telnet from rtnet box to host does not work but with tcpdump you can see the connection requests and replies from the host. Telnet from host to rtnet box also does not work, you can see only the connection requests with tcpdump. It seems that it's not possible to receive TCP data on the rtnet box, but ifconfig rtproxy shows as much RX packets as you see with tcpdump. any idea what I'm doing wrong?
