I'm a beginner un networking. I'm trying to connect an embedded linux to my Ubuntu 12.04.3 LTS by Ethernet.
I have configured the embedded system to work with a static IP adress (192.168.9.119).
I've add an eth1 interface on my Ubuntu, and set static IP to 192.168.9.118.
The embedded linux is directly connected to my eth1 via ethernet, but it doesn't works.
My ifconfig :
eth0 Link encap:Ethernet HWaddr 00:25:64:f8:7a:7a
inet addr:192.168.200.58 Bcast:192.168.200.255 Mask:255.255.255.0

SSH error message (I think it's useless to you but I put it anyway) :
ssh: connect to host 192.168.9.119 port 22: No route to host
Have you any idea on whats wrong ? Thanks
EDIT: Is this normal ?
user@linux:~$ ethtool eth1
Settings for eth1:
Cannot get wake-on-lan settings: Operation not permitted
No data available
route -n (on embedded device) :
Kernel IP routing table

192.168.6.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

And now, arp -n and route -n on Ubuntu :

what is the output of "ifconfig" on the embedded device ? – aseaudi – 2014-01-10T11:53:19.257
I've edited my post with it. – MokaT – 2014-01-10T12:31:36.677
there are packets counted in RX and TX. can you ping from .118 to .119 and vice versa ? if not, what is the output of "arp -n" and "route -n" ? – aseaudi – 2014-01-10T12:35:14.827
I've add route -n. arp -n doesn't exist on this linux. – MokaT – 2014-01-10T12:40:15.713
the ping does not work ? what is "arp -n" and "route -n" on ubuntu ? join chatroom "embedded" if you like to chat – aseaudi – 2014-01-10T12:55:48.693
No, the ping doens't work : host unreachable. I've edited my post again. – MokaT – 2014-01-10T13:05:59.933
