You can also do as follows on board
1) By default, the SSH server denies password-based login for root. In /etc/ssh/sshd_config, change:
2) restart SSH:
sudo service ssh restart
3) Disabled TCP checksum offload:
ethtool -K eth0 tx off rx off
4) connect to board from host via "ssh -Y root@ipaddress"
The above steps worked for me
