I tried the exact same steps as listed in init_inet(), but still
network is not connected.
Please see the steps below:
sudo modprobe rtnet
sudo modprobe rtipv4
sudo modprobe rt_e1000
sudo modprobe rt_loopback
sudo /usr/xenomai/sbin/rtifconfig rtlo up 127.0.0.1
sudo /usr/xenomai/sbin/rtifconfig rteth0 up 192.168.56.102 netmask 255.255.255.0
sudo modprobe rtcfg
#sudo modprobe rtmac
#sudo modprobe tdma
After this, rtifconfig shows:
$ sudo /usr/xenomai/sbin/rtifconfig
rteth0 Medium: Ethernet Hardware address: 08:00:27:52:BA:F1
IP address: 192.168.56.102 Broadcast address: 192.168.56.255
UP BROADCAST RUNNING MTU: 1500
rtlo Medium: Local Loopback
IP address: 127.0.0.1
UP LOOPBACK RUNNING MTU: 1500
And rtroute table shows:
$ sudo /usr/xenomai/sbin/rtroute
Host Routing Table
Hash Destination HW Address Device
00 0.0.0.0 00:00:00:00:00:00 rtlo
01 127.0.0.1 00:00:00:00:00:00 rtlo
26 192.168.56.102 00:00:00:00:00:00 rtlo
3F 192.168.56.255 FF:FF:FF:FF:FF:FF rteth0
Moreover, if I ping 192.168.56.101 IP address, it shows loopback address.
$ sudo /usr/xenomai/sbin/rtping 192.168.56.102
Real-time PING 192.168.56.102 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 time=5.6 us
64 bytes from 127.0.0.1: icmp_seq=2 time=7.5 us
In Ubuntu network, it still shows disconnected.
And it displays:
Ethernet Network()
device not managed
Do you think this problem is related to Virtual Box?
If I try on actual Ubuntu PC, will it work ?
Thanks,
Pintu
