Now where is the problem if ssh & ping to target works from desktop but not from laptop ?
I have been able to ssh to my target from my DESKTOP using following command :--- Target IP is fixed in /etc/network/interfaces
1> target ip - 192.168.0.202
target gateway - 192.168.0.200
target netmask - 255.255.255.0
2> Desktop ip - 192.168.0.204
Desktop gateway - 192.168.0.200
Desktop netmask - 255.255.255.0
3> ssh pi@192.168.0.202
----- ping 192.168.0.202
----->> works fine from desktop
4> Now i am trying the same with my laptop. My laptop also have wi-fi. I have disabled wi-fi function on my laptop. And connected my target to the laptop directly. I set IP address of laptop using.
sudo ifconfig eth0 192.168.0.240 netmask 255.255.255.0
5> Ping to target from my laptop gives following error :--

No gateway needed to access the local LAN, and the interface does appear to be up. – Matthew Lundberg – 2013-01-23T14:27:09.557
i have tried both adding a gateway & up onto the eth0. But both are not working. Could be firewall problem ? .... Any suggestion on this ? – Allan – 2013-01-24T05:43:53.023
