I have an Rasberry Pi B. I have copied Raspbian to SD card. I plugged RPI into TV and set it up. I enabled SSH at boot.
I rebooted, and took it to my laptop. I connected the laptop and Pi via Ethernet. I am using Ubuntu on laptop. I connect it, and I get a little spinning orb in the top right corner showing that it's connecting.
It never connects though. I always get a Disconnected popup telling me that it failed to connect via wire.
What am I doing wrong?
I had this problem too. The pi is looking for a DHCP server, but when you plug it straight into your laptop it won't be able to find one by default. What I did is (on Windows only) I went to network settings > change adapter settings > my WIFI adapter > properties > sharing and check the box marked "Allow other network users to connect through this computer's internet connect" and finally select your ETHERNET adapter from the drop down. Then reboot the pi or reconnect it and if all goes well it should connect. Then you can use ifconfig (on the pi) or a tool like nmap (on your laptop) to find it's address and SSH into it.
The Raspberry pi and your laptop need to be on the same subnet. Therefore go to your internet settings on your mac and set a DHCP with manual address, e.g. 192.168.1.10. Then on your RPi, connect it to a screen and keyboard and give it a manual address such as 192.168.1.20. When the RPi has booted, type in
sudo nano /etc/network/interfaces
Now look for the eth0 line which corresponds to the Raspberry pi ethernet port and edit the file to look similar to this:
iface eth0 inet static
address 192.168.1.20
netmask 255.255.255.0
gateway 192.168.1.1
Once the file has been updated, use ctrl x to save and exit. Now reboot the pi and test if the connection works by pinging the laptop: ping 192.168.10.
Hope this helps!
